PC Stress Test free software for Windows 10/8/7

If you have built a new computer and wanted to test it, or if you need to identify hardware faults on your existing system, you will want to consider subjecting your computer to a PC Stress Test. A PC Stress test software for Windows will perform various tests on your computers parts like processors, graphics, memory, physical disk, optical drive as well as networks. But it is something that you should subject your PC to, very often, as such test will subject your hardware to excessive stress to find out how well they perform under such stress.

If you are on a new system, you may carry out these tests with some ease of mind, but if you are on an old system or suspect that some part of your hardware may be failing and you want to identify which one, then you may want to first back up your data before carrying out such a PC Stress Test, since your components may be placed under severe stress.

Do note that you should never run these tests on unstable, old or overclocked systems, as it can lead to a crash or system failure, and make sure you know where the Stop button is, just in case you feel you need to stop the test.

Here are some free PC Stress Tools that will help you check most of your components like CPU, GPU, RAM, Disk, Optical drives, etc.
