Do the same with your graphics card, PCI-E cards, and anything else that plugs into your motherboard. Reboot your computer and see if the problem has been fixed. What may seem like a hardware issue could be caused by your operating system, a faulty driver, or some other software-related fault. Ruling it out will edge you closer to the real problem. Try restoring your system to an earlier point, if possible.
Uninstall applications you recently added. Roll back drivers if you made changes to them. You can also try running a different operating system from an optical disc or USB drive. There are many versions of Linux you can run this way. If they boot up successfully, and everything works as it should, your problems likely aren't hardware related. In that case, your best option may be to reinstall or factory reset your operating system. Error messages may give you some vital clues about what's going on.
Write them down, photograph them, or copy and paste them into a documentwhatever works for you. Sometimes, they'll give you a clear idea of what needs fixing. Otherwise, enter the message into a search engine and see what comes up. Often, you'll find forums, articles, and other pages that address the exact problem you're having.
Some of your computer hardware may give you audible signs it's malfunctioning. Traditional hard drives already produce a quiet click sound, for example.
If that significantly changes, it's possible your drive is failing. You should also pay attention to your fans. If they spin up, that's good because it means your board has power. But if they are particularly loud or run at full speed constantly, your PC may be overheating somewhere. If something in your PC is overheating, you need to think about ways to keep it cool.
Windows and Mac operating systems both offer a troubleshooting environment known as Safe Mode. Safe Mode disables non-critical applications and processes, which theoretically makes it easier to isolate problems. Most Windows computers allow you to enter Safe Mode by pressing the F8 key as your computer is booting up.
On a Mac, enter Safe Mode by pressing the Shift key while your computer boots up or immediately after it boots up. Once your computer is in Safe Mode, launch the problematic software and try to replicate the problem you had while your computer was in normal mode.
If you don't have the same problem in safe mode, there's a good chance that the issue was caused by your OS or another program, not by the application you are troubleshooting. As a final troubleshooting step, you might defragment your computer's hard drive. Defragmenting rearranges your hard drive's file structure so that the system runs more efficiently.
Defragmenting will probably be most useful if you're experiencing overall sluggishness on your computer, because defragmenting is meant to make your entire system run faster. Note that defragmenting a hard drive applies primarily to Windows-based computers.
Most recent Windows editions — including XP, Vista, and Windows 7 — include a built-in disk-defragmentation tool. Be aware that defragmenting a hard drive can be time-consuming, so make sure to perform this task when you will be away from your computer for a few hours.
If the tips listed above haven't solved your software problem, it may be time to call tech support. At minimum, you'll be able to help them narrow down the problem by describing the troubleshooting steps you've already taken on your own. You may be trying to access this site from a secured browser on the server. Please enable scripts and reload this page. Turn on more accessible mode. Turn off more accessible mode. Skip Ribbon Commands. Skip to main content. Turn off Animations.
Turn on Animations. Make sure as many of your installed applications are updating themselves automatically in the background, and you should run into fewer computer issues as a result. You might think that leaving older, unused programs on your hard drive is pretty harmless, but as more and more applications mount up, your operating system has to work harder and the files on your computer get broken up more often and spread out further as your computer tries to save them—something known as fragmentation.
As a result, the amount of free storage space can quickly become limited. You can uninstall applications you no longer need from the Apps section of Settings in Windows, or by dragging the app shortcut into the trash on macOS. Some macOS apps can be removed from the Launchpad by clicking and holding on an icon until it shakes, then clicking the X icon.
The same goes for your browser —having too many extensions and add-ons can lead to a serious slowdown or some erratic behavior, so limit your extensions to the ones you actually need and use. In Google Chrome, click the three dots in the top right, and go to More Tools , then Extensions ; in Firefox choose Add-ons from the main app menu; and in Microsoft Edge, choose Extensions from the main app menu.
If your computer is running low on disk space, it can lead to a number of problems, including occasional crashes and slow performance. A loose power cable, unplugged keyboard or monitor, or another connection may be to blame. Check if your operating system is due for an update. The process will vary depending on if you need to complete a Mac or Windows update. If a specific program is causing your computer to crash, check for new versions or uninstall and reinstall the application.
Delete anything that you no longer need, including applications and programs, media, and documents. You may be experiencing other issues caused by computer hardware, such as your motherboard, power cord, battery, or other components. Wi-Fi is another common culprit, so run a speed test or contact your service provider before bringing your device in. If all else fails, turn to the experts.
