We’ve all been there, sat at the computer when all of a sudden, it crashes. Receiving an error message in the middle of a task is frustrating, especially if you don’t know why.
Or, your computer has become very slow, taking ages to boot up a program. A lot of people assume their computer has broken, and don’t want to invest in a whole new device.
It can be tricky to figure out what the problem is or how to solve it. Is it a software issue or a hardware problem? Once you find out, it makes the issue much easier to solve.
In this article, we will be looking at the most common computer issues. We will also find out how to determine the difference between software or a hardware problem.
Software or Hardware Problem: How to Tell the Difference
In this article, we will dive into the specific problems you may encounter and how to identify the cause. But first, let’s get an overview of how to determine which is a software or a hardware problem.
The differences between software and hardware are pretty simple to figure out.
When it comes to software issues, they are usually easy enough to fix. They very rarely result in a complete system shut down. You can often fix these by clearing the cache or uninstalling malicious apps.
When it’s a hardware problem, it’s usually more severe. You can tell it’s a hardware issue if the computer will not boot up or if it boots up with lots of issues.
You may have to open up the machine and looking at what could be wrong. Getting a professional could be the best course of action.
Now, let’s take a look at some of the most common computer problems you may face. We’ll help identify which are software and which are hardware problems.
One of the most common computer problems people report is a slow computer. There are a couple of ways this can happen.
One is when it takes way too long to complete a task, such as opening a document or program. Another is when a computer has become outdated, so the software can no longer keep up with newer programs.
One of the most common causes of a slow computer is from too many applications attempting to boot up at once. Another is from downloading and installing software with malware attached to it.
Not to worry, you can fix these. A slow computer is always a result of software, not hardware problems, so it’s much easier to solve.
Clean your cache, install and run antivirus software, and defragmenting should fix it.
Not Booting Up
One of the most frustrating computer issues is when the device will not boot up. If this is an issue you’re having, it’s a hardware issue.
There are a few causes for this. One could be a loose connection in the computer, where you only need to plug it back in. But it could also be a much more severe problem.
It could mean that too much power is getting to the components in the computer. It can cause some serious damage and cause it to stop working completely. It’s important to get this fixed as it can cause the power supply to shut down and kill your computer.
But, if your computer does start up but then fails midway through, it could also be a software issue. Try re-installing the operating system completely. If it’s a software issue, this should solve it.
The Dreaded Blue Screen
The dreaded blue screen of death is something every computer owner will encounter. There are a few causes for this, so let’s get into it.
When your computer shows the blue screen, you might have a software issue. It is a sign of drivers which have malfunctioned. Try uninstalling them, resetting the computer, and reinstalling them.
But if you are getting the blue screen on a regular basis, it is often a sign that the hardware is malfunctioning. If you’ve fixed the drivers and the problem persists, it’s a hardware problem.
There could be a few causes. It may be a problem with the motherboard, internal RAM, or graphics card. With these issues, you’re best off finding a professional who could fix them. Or, you can buy new components to replace the broken ones.
What To Do Next?
After you’ve got these problems fixed, don’t continue to ignore your computer. Even if it seems to be running fine, there could be problems on the horizon, so you need to keep your computer healthy.
One way to do this is by installing cleaner programs which will clear your cache and useless files. They stop your computer running slow and keep it in top form.
You should be more wary of the programs you install; they may contain spyware or malware. Also, keep aware of any issues such as overheating or graphical errors. These are hardware problems which are fixable if caught early
Software or Hardware Problem: Now You Know
Now you know the differences between a software or hardware problem. Now you know how to identify and solve them, you can fix it by yourself.
It sucks when your computer stops working like it should. But when you know what to do, it makes it easier to deal with.

You’re right in the middle of something and your computer starts acting up. Is it the app you’re working in or your device that’s the problem? How can you tell the difference between hardware and hacking?
Most problems are software problems. Some are definitely hardware problems. And some can be caused by one or the other. This chart lists 16 of the most common problems. Knowing where to start troubleshooting can save you lots of time. And if you need to call in the cavalry, you’ll know which customer service department to call.
Note: Of course, there are exceptions to the rule.
|Computer is slow||Could be malware, too many start-up items (Windows) or build up of temporary files||Could be hard drive is fragmented or starting to fail, not enough RAM or an old CPU|
|Computer keeps restarting||Could be automatic OS update problem, adware, virus or other malware||Could be graphics card, motherboard or network card drivers|
|Keyboard, mouse, printer or other peripherals aren’t working properly||Could be driver issues||Could be computer port issues or peripheral component issues|
|Peripheral commands interpreted incorrectly||✓|
|App command not working||Software if it’s happening in only one app||Hardware if it’s happening in more than one app|
|Internet is slow||Could be an app in background is consuming the bandwidth||Could be hard disk failing|
|Downloads take forever||✓|
|Attachments won’t open||✓|
|PC blue screen of death||✓ (although it could be your drivers)|
|Corrupt files or long delays accessing files||✓|
|Google performing oddly||✓|
|Sudden shut off…or sudden anything weird||✓|
|Graphical errors like your computer screen is jumbled||✓|
If you’re lucky, your problem is a software problem that can be easily resolved by running a repair utility or uninstalling and reinstalling if it’s a desktop app or logging off and on again if it’s a cloud app. To keep problems away, keep your software updated. To keep your computer clean and in good shape, pay attention when things seem weird so you can start troubleshooting before it ruins your day.

Some computer users are having tough time to distinguish between a hardware or software problem. To help you on this, here are some of the points you need to know.
Signs of Hardware Related Problem:
- Dead signs. You’ll notice there is no signs of activity such as lights, screen info and sounds, when the power is on.
- Unusual machine noise is a sign there is a problem with your hardware.
- When you can see physical signs like visibly cracked, broken or may have a loose-fitting part.
- The problem occurs when a liquid is spilled on the machine.
- Randomly, restarting itself and somehow the machine is getting very hot.
Signs of Software Related Problem:
- The machine stops working through the start-up.
- The programs are not working properly or giving error messages more often.
- The PC is processing very slow.
If you think you have a hardware/software issue, you need to check these points and understand:
- Is your PC under warranty? If your answer is yes, contact the supplier or manufacturer for advice for the repairs.
- If you can access your files and documents, make sure you save everything for back-up copies. Often when there is a hardware problem, especially with the hard disk, the data may be affected when it is repaired.
- Usually, if this is a software issue, troubleshooting requires removing the new program (or the programs installed/updated when the problem starts to manifest). Some of the possible ways to know if it is a hardware problem – the need to update drivers, reinstalling the OS (operating system) and installing older drivers.
Hardware Basic Troubleshooting
Before anything else, it is a rule of thumb to ground yourself (metal chassis of the PC). This will keep you safe before touching the internal components.
Note: You need to disconnect almost everything inside the CPU, so you need to remember the connection of every parts so you can put it back again.
- First, shut down the computer and unplug it. You can also set up the grounding the equipment safely.
- Start disconnecting all the storage drives, as well as the optical from the motherboard.
- Take out all of your add-in cards, the same as the video card.
- You also need to remove the RAM but don’t touch the primary slot (the DDR or the silkscreened, located on the board).
- Include to unplug all of the external and internal connected from your computer such as power, keyboard, monitor cable, internal speakers, reset switches, mouse, and everything else.
- Next, clean everything. Pick with your hand, those with larger dust piles and you can use compressed air on those Heatsinks. Fans need to be cleaned with cotton buds/swabs or a toothpick, don’t use metal for this part.
- Put everything back together, double check the connection and power it on.
- If you still encounter the same error, take your PC to a reliable technician.
Software Basic Troubleshooting
Checking your OS for some troubleshooting is also related to your software issue. So, you need to go to the Operating Systems’ basic troubleshooting section and then click the Basic Troubleshooting section.
After you had gone with that, and you are having errors, contact your reliable technician for software support.
So, you are in the middle of an important task, and suddenly your computer starts acting funny. You tried to reinstall a software, pulled out and plugged in the cable, but still, it doesn’t work the way it is expected to do. Sounds familiar? Well, a computer problem can happen to any computer at any time. And it won’t give you a notice before its arrival, most of the time!
Before you can do anything about it, you need to figure out if it is a hardware or software issue. The below pointers will help you identify if your computer is having a hardware issue or a software issue or both.
Common Hardware Computer Issues
One of the most common of the hardware issues side is a slow device. This happens especially when there is not enough RAM, the hard drive is fragmented, or you are using an old CPU. If your computer gets auto restarted frequently, then you can assume that the problem is with the graphic card, card drivers, or motherboard. There could be issues with the network too.
Other symptoms of common hardware issues include:
- PC shutting down suddenly,
- The blank Blue Screen of Death,
- A jumbled computer screen, which can be due to graphical errors,
- Unusual noises from the PC, etc., and
- Corrupt files or long delays in assessing files.
You can also experience slow internet at times, which may be related to hard disk failing, which is a hardware issue. If the app command is not working, then it could be a hardware issue if you’re experiencing it for multiple apps.
Common Software Computer Issues
Like hardware issues, a computer can experience different software issues as well. For example:
- Too many apps that run at start-up can make a computer slow,
- A computer that is often freezing,
- Malware infection with pop-up ads,
- Attachments not opening
- An operating system update that fails to update or causes issues when it does.
- When an update fails to install, you will see an error message on your screen. If you read the error message, you will know the exact reason. For example, if an application is causing a problem, you can uninstall the program, or check if you have the latest version updated.
Common Computer Issues that Could be Both
Sometimes the distinction isn’t so simple and the problem could be a result of either the software or the hardware.
For example, a computer can become slow either for hardware or a software problem. Too many apps running during start-up, a malware attack, or a build-up of cache files in temporary memory can make the computer slow (software problem) while an insufficient RAM (hardware problem) can also turn a computer slow.
Similarly, the blue screen problem can happen due to issues with the graphics card (hardware problem) or due to a malware attack (software problem).
Then there could be problems related to the peripherals like mouse not working, printers not responding, or keyboard not working properly. All these could be due to driver issues, which are a software problem or port issues, peripheral issues—all being hardware issues.
Computer restarting is another common issue that can be due to both software and hardware issues. If you are experiencing your computer restarting, then it can be either due to motherboard or network drivers’ issue (hardware) or problem with adware, virus, malware, OS update problem, etc. which are all hardware problems.
Another common problem is app command not working properly, which could be due to hardware—you know it when you experience it for more than one app. But if you see the problem happening for only one app, it could be a software issue.
How to Solve the Issue
A computer is a machine, and just like any other machine, they may show different issues. If you know how to identify a hardware or software problem, you can usually fix them yourself. But, if you are not sure or if they become more of a headache than you’re willing to deal with, then you can always take the help of local services. For that, you can look up for local services by using the keyword “computer repair near me” online. A local repair service can help you pinpoint the exact cause of the problem and offer solutions accordingly.
Computer problems are common if you use it regularly for your work. Knowing how to diagnose the issues and getting help to fix it will save you from last-minute panics!
Then, there are DNS servers you should hook up with, which might additionally encounter points. Finally, there’s your native hardware, which includes your router, computer and network software. The more you employ your PC, the extra warmth is generated by the processor and exhausting drive.
To stop this from occurring, you must ensure to make use of just one antivirus program, avoid downloading internet browser helpers, and in addition keep away from software that declare to hurry up your computer’s performance or Internet connection. Uninstalling packages you do not use anymore may also help improve your computer’s processing velocity, and closing these you aren’t actively utilizing will most undoubtedly enhance its efficiency as nicely (i.e. uTorrent).
It lacks all that stuff that computer systems include today making it out of date. The other hardware went obsolete long before the two Pentium 4’s that are still working over 10 years later.
Accuracy and precision are inherent in measurement designs. They are no matter they are, and might only be improved by bettering the device. Multiple measurements can enhance the accuracy of the statistics of a measurement, however they can not enhance the inherent measurement error. The percent error is calculated because the deviation vary of a measurement from the final, greatest fastened metric level.
- That means reinstalling Windows or utilizing the Refresh or reset feature on Windows 8.
- Computers can encounter both software program errors or hardware errors.
- The finest method to determine whether or not the problem you could have is a software program or hardware one is to chew the bullet and restore your computer’s software back to its default state.
- See whether or not the issue nonetheless persists after you restore its operating system to its default state.
- If you continue to see the identical problem – for example, if your computer is blue-screening and continues to blue-screen after reinstalling Windows — you realize you’ve a hardware problem and must have your computer mounted or replaced.
Accuracy, Precision, and Percent Error all need to be taken collectively to make sense of a measurement. As a scientist and statistician I would have to say that there isn’t any higher restrict on a “% error”. There is only the mandatory (human) judgment on whether or not the information is refers to can be helpful or not.
Computer sluggishness is a typical cause of frustration for many expertise customers who’re increasingly reporting their machines to perform slowly. The underlying explanation for sluggishness is dependent upon every individual computer and the way it is maintained, although most customers think little or no about this particular side. The OS can also crash when it fails in its job of managing system resources appropriately.
This means the fan should work twice as onerous to chill the machine down and will make more noise in doing so. Your fan is designed to deal with this level of warmth and to function quietly, but this kind of intensive use will finally cause a failure. So if you can audibly hear your fan, enable your computer time to cool down earlier than using it once more.
It is feasible for the OS to achieve a state of impasse, in which multiple applications every have control of some resource one other program needs, and each is waiting for the other to relinquish management of the useful resource. Alternatively, the system could be switching back and forth between a couple of applications, each of which wants a significant proportion of memory resources.
Impact Of Turing Machines On Computer Science
An overheating computer is the most typical explanation for random crashes. If your PC or laptop isn’t experiencing adequate airflow, the hardware will become too hot and can fail to operate correctly, leading to a crash. Every computer is offered with a fitted fan designed to counter the warmth the machine generates.
How to Tell a Software Problem from a Hardware Problem

Determine If Your Computer Needs Hardware Repair:
There are two main types of PC problems: those that generate from software issues and those that are caused by a hardware malfunction. So, before you can fix a malfunctioning computer, you must first identify the source of the problem. Most software-related issues can be fixed by owners themselves. Hardware problems, however, may require professional hardware repair services. Here are some of the hardware components that fail more often.
Hard-drive problems usually come in the form of slow booting, files becoming corrupted, or operating systems refusing to load. If you experience long delays when accessing files from your hard-drive, then you may have to start looking for a new storage device. Once a hard-drive develops physical problems, there is nothing you can do to fix it.
The CPU (Central Processing Unit) is the brain of your computer. Although it rarely happens to malfunction, CPUs can sometimes overheat and create serious problems. Your computer may become slower than normal, programs may freeze up, and you may not be able to access some demanding games or encoding videos. However, a thorough cleaning and new cooler may fix most problems with your CPU. Just make sure you let a professional hardware repair service provider do the work for you.
Applications write data into RAM (Random Access Memory) and then read it back when they need it. If your RAM is malfunctioning, then you may experience blue screens, crashes, and file corruption.
Most graphic card problems occur when rendering 3D content. In other words, if your computer crashes when you play a demanding video game, then your graphic card may be the culprit. There are plenty of free applications that you can use to test your graphic card.
A malfunctioning power supply is very difficult to diagnose. Sometimes, the source may deliver too much or not enough power to a component, causing your entire computer to go haywire.
It is known to us that apple iPhone is one of the most successful mobile devices, no complsints and are selling like hotcakes in store, online – simply sellular. Apple iPhones are known for its quality and for its premium touch and appearance, but that does not mean that Apple’s latest iPhone devices are flawless. With the recent launch of Apples newest flagship device some problem and user complains also arises. I’ve been using an iPhone for about 4 years and did encountered different issues on my iPhone on both hardware and software Aspects.
This article will help you troubleshoot or address your Apple’s iPhone hardware and software issue on no simply sellular complaints.
Facetime Camera ‘Crescent Gate’
‘Crescentgate’ which sees the front camera (Face-time Camera) slipping inside the case.
Bring your iPhone to the nearest service center or Apple Authorized Dealer. Apple is handing out new iPhone 6 handsets to customers affected by the latest hardware issue, rather lamely dubbed ‘crescentgate’, which sees the FaceTime camera slipping inside the housing.
iPhone 6 Plus ‘BendGate’
I’m sure that you already heard or read about the issue even on the simply sellular. Users are complaining that iPhone 6 plus get bended under strain especially if you’re putting your iPhone 6 plus on your tight jeans. There’s a specific weak spot within the particular framework right beneath the volume control keys which allows that to fold without difficulty along with pressure added inside right spot.
I don’t think if we do really have a fix for this since I don’t think if this is really an issue and I don’t have simply sellular complaints. Let’s be honest and get straight about it. For sure Apple’s iPhone6 plus will bend if you put enough pressure to it. Even other phones will be having the same issue if you put on the same situation.
But just in case you’re facing the iPhone 6 plus BenGate issue, Apple’s authorized service center will surely help you fix it.
Cracked or Damaged Screen iPhone – Accidentally dropped or intentionally thrown.
I had my iPhone dropped in the parking and ran over by a car. The phone is working fine when I recovered it but the screen is cracked and the aluminum body is already bended.
You have two choices to address the problem. First is to bring it to the authorized service center and have it replaced by a new unit by paying half price of the brand new device. Your second choice is to have it repair on the electronics repair shop to replace the aluminum case and the screen of your iPhone. You can save a lot of bucks in the second option but you’re not at ease of the quality of your iPhone since it might have loosen some of its parts due to the heavy pressure it went through.
iPhone 6 Screen Easily Get Scratched
There are rumors that the Apple’s iPhone 6 and 6 plus screen get easily scratched even you take extremely care for it.
I’m not a fan of screen protector both film and tempered glass. I have my iPhone 6 with me without having screen guard for almost a year no noticeable scratch on the screen. But, if you’re that ‘OC’ about your phone, there are lots of screen guards available in the market. Go and get one for your loved iPhone 6.

Many computer problems can be caused by hardware or software failures, and figuring out which is to blame can be quite difficult—unless you know the simple way to diagnose hardware problems. If you determine you have a hardware problem, all you need to do is fix or replace the hardware. If you determine you have a software problem, then you can start searching for solutions.
This is why people have such a hard time troubleshooting a black screen on a computer or even a blue screen of death as they can be caused by both hardware or software.
The Simple Way To Find Hardware Problems
If you think you might have a hardware problem, all you need to do is rule out software problems. That sounds difficult—after all, you have so much interrelated software on your computer, it’s almost impossible to try turning off each program separately to find which one might be causing your problem.
But you can turn off all of the programs on your computer at once. You can even temporarily replace every program on your computer with a substitute program. And you can do all of this testing practically for free. (It might cost you as much as one burnable DVD disc—about $0.25 around here.)
How do you do it? You boot your computer using a Linux live CD, DVD, or USB stick. This runs Linux on your computer for one time only. As soon as you remove the disc or stick and reboot your computer, it goes back to your regular version of Windows.
Since Linux is entirely different than Windows, it’s almost impossible to have the same software problem on both Windows and Linux. If your computer malfunctions on Linux the same way it does on Windows, you can be assured that you have a hardware problem.
But if your computer works correctly on Linux and not Windows, then you probably have a software problem.
Hardware Problems Linux Can Help Diagnose
If you have one of the following problems, you can determine whether or not it is caused by bad hardware by booting Linux:
• Computer monitor problems: if your display isn’t working correctly, try booting Linux. If the display also doesn’t work correctly on Linux, you have a hardware problem.[easyazon-image align=”right” asin=”B008MPBWXO” locale=”us” height=”350″ src=”http://ecx.images-amazon.com/images/I/51CtLK%2BNGVL.jpg” width=”350″]
• Connection problems: dial-up, ethernet, wifi, and Internet problems can all be tested using Linux. Just see if Linux can connect when Windows can’t. If it can, then you have a software problem. If it can’t, start looking at hardware problems.
• Random crashes or reboots: many seemingly-random problems on your computer can be caused by overheating, bad memory, or a failing video card. But they can also be caused by malware and regular software bugs. Run Linux on your computer for a day—if you still have problems in Linux, you know it’s a problem with your hardware and not something caused by malware.
How To Use Linux
Running Linux on a modern computer has never been easier. If your computer has a DVD burner, you can burn a DVD and boot off of that. If you don’t have a DVD drive, you can use a USB stick.
To test whether your hardware is broken, you can use practically any Linux distribution, so choose whichever one you want. If you’re undecided, try Ubuntu Desktop, which is one of the most popular distributions.
To create a live CD or DVD, go to the website for the distribution you want to use and download its ISO images. Insert a blank CD or DVD into your drive and use a burning application to burn the ISO image to the disk.
To create a bootable USB stick, get a USB stick with at least a couple gigabytes capacity and backup any important files on it. (Creating a bootable USB stick will wipe out any existing data on the USB stick.) Then download the Universal USB Installer from http://www.pendrivelinux.com, run it, and use its easy wizard interface to create your bootable USB stick.
Changing Your BIOS Settings
Some computers are configured by default not to boot from CD, DVD, or USB stick. You need to enter bios to change their configuration if you want to use Linux.
1. Reboot your computer.
2. On the first screen, press the key which takes you to the “configuration” or “setup” menu.
3. Go to the screen in the setup menu which lets you change the boot order.
4. Then put USB drives and CD-ROM drives earlier in the boot order than your regular hard drive.
5. Save your changes; your computer should automatically reboot.
6. All you have to do is insert the disc or stick before rebooting to start up Linux.
Common Linux Problems
Linux live CDs, DVDs, and USB sticks are different from Windows—or even permanent Linux installations. If you have the following problems on Linux, it may not be a hardware problem:
• Linux runs slow. CDs, DVDs, and USB 2.0 are not designed to run as fast as modern hard drives, so Linux will boot more slowly than Windows and opening programs for the first time after booting will also go slower than you may expect. This doesn’t mean there’s anything wrong with your basic computer hardware.
• Some hardware doesn’t work at all. Linux doesn’t support some hardware, especially printers and scanners.
• Not all hardware features are supported. This is especially the case with recent graphics cards. Linux will display a regular desktop on almost any graphics card, but it may not support 3-D graphical effects.
It takes only a few minutes on a broadband connection to download a Linux image, burn it to disc or USB stick, and reboot your computer—but it can prove that your problems are hardware related so you can fix or replace the broken part with confidence that you aren’t wasting your money. For that reason alone, a Linux bootable disc or USB stick belongs in your computer repair kit.

I’ve been using Linux (Ubuntu) for nearly a year and it is better than all windows combined together, the problem solving is so fast an easy. Linux isn’t an easy OS to use but if you get it it perfect.
A malfunctioning computer can be extremely troublesome and with a variety of problems, it can get difficult to differentiate between a software and hardware problem. Many hardware and software problems can also lead to similar symptoms.
Here below are few common problems and simple ways to differentiate if it is hardware or a software problem.
- If your computer refuses to start then it has got to do something with the hardware. It could be a simple loose connection within the computer or something complicated like a problematic hardware. However if your computer starts and fails when fully booting up, then it could be either a hardware or software issue. In such cases, it’s advisable to perform a re-installation of the operating system. If this doesn’t solve the problem, then it has to be some issue with the hardware. A problematic CPU may result in the computer not booting at all. If the CPU is overheating, it may lead to blue screen when it’s under load.
- Also a faulty power supply can be tough to identify. When there is too much power being sent to components, it can cause damage to it eventually leading it to malfunction. If the power supply dies completely, the computer won’t turn on and nothing will happen when you press the power button.
2. Blue Screen Problem
Blue screen problem usually is an indicator that there is some fault in the hardware or poorly programmed drivers. When you encounter the blue screen problem, check recently installed hardware or installed drivers. If there is no problem with the drivers, then you can assume that the problem is with the hardware such as motherboard, graphics card or RAM.
3. Corrupted Files
If files on the hard drive start to become corrupt, there the problem lies in that hard drive itself. Long delays when accessing files or not being able to open files can also be due to some viruses or malware. Run a complete scan and if there are no viruses, the hard drive is under fault.
4. Random Computer Crashes
If the RAM is problematic, it can lead to crashes, blue screens or file corruption. The data is written on the RAM for short term storage and a faulty RAM will lead to storage of incorrect value on it.
Fans are essential to keep the CPU from overheating and if the fan fails in the computer, it may lead to overheating and can cause CPU or graphic card problems. This will eventually lead to computer crashing and not booting.
Resolving a software problem isn’t is as hard as hardware but with reliable computer services, fixing both faulty software and hardware won’t be much of an hassle.
