Strange Noises
Overheating

The Computer Won’t Turn On
This can be a computer user’s worst nightmare. You hit the power button and nothing happens. Any number of things can cause this computer problem — it may be something as simple as a loose cord, or as serious as a dead power supply.

Another common PC problem is when the computer turns on and the fan and lights come on, but the machine doesn’t boot, or shows a blank screen. This could be anything from a dead (or unplugged) monitor to a dead hard drive or corrupted boot sector.

Blue Screen of Death (BSoD)
The infamous “blue screen of death” has frustrated many a user, as it brings the computer to a halt and displays an error message that’s utterly indecipherable to most computer users. Lockups can be caused by any number of issues — sometimes it’s buggy software, or a system running out of memory.

Many people think of blue as a calming color; however, when it comes up on your computer screen with a bunch of white text, it probably has the opposite effect. The blue screen of death (BSoD or STOP Error) may appear to be one of the scariest computer problems you’ll come across. However, all your computer may need is for you to reboot it. This STOP error appears on your screen for a variety of reasons: failing hardware, damaged software, corrupt DLL files, problems with drivers and more. The remedy for a blue screen of death depends on the original problem. The screen provides you with codes that can help you identify and fix your computer problems.

Sometimes it’s a bad hardware driver causing the issue. More seriously, it can be a sign of overheating, RAM going bad, or the hard drive failing. Components get loose inside the machine and can also cause computer errors, sudden lockups, or even spontaneous shutdowns.

Missing DLL File
Error messages about “missing files” – especially those that end in the DLL (Dynamic-Link Library)extension – are unfortunately very common. There are a lot of possible causes for these types of problems, meaning there are several troubleshooting steps you’ll need to follow to cover all your bases.

Dynamic-Link Library (DLL) files house information for your operating system on how to perform certain functions. Occasionally, your computer loses DLL files or something damages them. When your PC can’t read the particular DLL file, it doesn’t know how to respond in certain situations. You may have a missing or corrupt DLL file if you receive an error message every time you perform a certain function, such as saving. If your computer problems are stemming from missing and damaged DLL files, you can restore them by downloading them back onto your PC.

Applications That Won’t Install
You’ll occasionally run into an error when installing software on Windows. The installer may refuse to run, report an error code, say it’s unable to write to a folder, or even silently fail. You’ll need to troubleshoot the problem so you can install software normally.

If you’re having trouble with an application not installing, it may be because your computer doesn’t have enough hard drive space. If this is the case, you need to free up some space. This is one of the computer problems that’s, well, least problematic. You can free up some hard drive space by getting rid of files and folders you don’t need. These may be temporary files, duplicate files or data for software you’ve uninstalled.

Please follow these steps if applications that Won’t install

Run as Administrator
Consider x86 vs. x64
Uninstall the Previous Version of the Software
Check for Malware
Abnormal Applications Behavior
Computer problems that involve applications acting strangely oftentimes leave you wondering what has happened. Your application has been working just fine, but now, seemingly without reason, it is doing something strange.

For instance, your Word document will no longer show the top margin of your document. It still says it’s there, and when you print it, there’s not a problem. You just can’t see it on your monitor. If this is happening, you may want to restart your computer. Conducting an internet search for the type of problem you’re experiencing or consulting your user manual may help you as well.

Slow Performance
When you delete files and applications from the computer, all kinds of junk can get left behind. Useless files and data can accumulate and degrade system performance. Ironically, antivirus and anti-malware software, while vital to the health of a computer, can slow down a PC’s performance. Low hard drive space or not enough RAM in the machine can also cause computer errors and slow down the machine.

There are several reasons software might be running at turtle speed. You may have computer problems that involve your operating system or an application, your operating system might be missing updates or your computer doesn’t have enough hard drive space. If you don’t have enough hard drive space, you can scan, clean and optimize your hard drive.
