Anyone with a PC can attest to the fact that as great as they are, things go wrong. Whether it's a problem with the programming or a hardware error, when there's an issue with a computer, it can seem like the end of the world. Fortunately, there are a number of free PC scans that can help even a beginner diagnose problems.

Free PC scans are available for all kinds of issues related to hardware and software. They can help diagnose and even fix everything from Windows registry issues to problems with viruses or spy bots. Let's consider some of the major forms of free PC scans that are available and the issues they can help in spotting and sometimes even fixing.

Virus scan
Many reputable software companies offer free PC scans for viruses. These are generally watered down versions of their paid software, but they can be real lifesavers (or PC savers) for those who are running without virus scanning software. The only problem with these is that they might identify a virus, but they won't always provide what's needed to remove it. Even still, it's better knowing what the problem is rather than not. If you go on the Internet and accept e-mails, you do run a risk of contracting a computer virus. These scans can really help ferret them out and assist you in fixing problems they might be causing with your system.

Ad ware scans
Sometimes e-mails and other downloads include adds ons that are called "ad ware." These add ons track your actions online in one way or another and send information to the company or entity about your habits online. To remove these, many software companies offer free PC scans that not only find, but eliminate ad ware on a hard drive. Ad ware won't necessarily harm your computer, but it can slow it down.

Registry scans
The Windows operating system is a complex one that relies on tons of files being exactly where they're supposed to be. When a single file gets out of place or becomes corrupt, it can wreak havoc on a computer. A free PC scan to check the registry can actually help you troubleshoot all kinds of issues.

Hardware scans
You might need to go to the manufacturer's site for your motherboard, hard drive, video card or so on, but oftentimes companies that make computer parts also offer free PC scans to troubleshoot their products. These can be very beneficial if you suspect any trouble you are having with your PC is coming from a hardware issue.

Free PC scans can be found all over the Internet to find and fix troubles ranging from hardware to viruses. Before you run a scan, it's a good idea, however, to know where it's coming from and that the creator is reputable. Software companies, parts manufacturers and other such reliable sources are generally good bets. When used properly, free PC scans can assist in fixing some of the biggest problems a computer owner might run into. Remember though, they aren't fool proof and sometimes problems just can't be fixed without replacement parts.
