PC Guru Diagnostics

PC Guru Diagnostics is a free-to-use program designed to spot a number of common faults with your computer.

Think you may have a problem? Not sure? PC Guru Diagnostics may identify a fault that your anti-virus or other standard diagnostics have failed to detect, such as a hardware failure or internet connectivity problems.

It's free to use and takes no more than one minute to install and a few seconds to run the test.

Compatible with Windows 2000, XP or Vista only.
