The first test you should perform is the check of your CPU which stands for central processing unit. There are a few websites that offer free CPU benchmark test programs. Most require you to download a small program that you will need to extract and run. After testing your computer hardware you should see your results in just a few seconds.
You can then use the results of this test to compare the speed of your computer's central processing unit to that of other people by visiting a PC benchmark website. A simple search on the major search engines will provide you with suitable websites.
This method may be long-winded but at least you will then know whenever the most important part of your PC is up to the job of running your games and resource hungry applications. You can arrange all sorts of benchmark tests on such websites but be careful when downloading any program off the internet. Always virus scan any free program first as they could be infected with malicious viruses or malware.
If you are unsure about performing your own tests or are worried about the security aspect of downloading programs that you are not sure are safe to use then one of the best methods PC experts use for themselves is to download a specialist program that will scan your hard drive for errors and other diagnostics such as disk defrag and registry file problems.
Modern software is now capable of detecting the most deep-rooted problems with computers, including CPU issues and even those that might not seem problematic or are hard to detect. For instance many computer users may blow a hardware problem when in fact a simple scan may expose a software file problem such as a corrupted download or fragmented files that slow down even the speediest computer.
