I have PC Wizard running on my system to check health of system. But I noticed there's problem associated with Hardware test compatibility in PC Wizard. Whenever I press Hardware Test Compatibility (both hardware or processor) button, system freezes. I can't move mouse or keyboard. Screen just freezes. But it's not happening all the time. Sometimes there's no freezing during this test (I can move mouse or keyboard). I thought it was software. So I reinstall it but nothing happened. No overheating at all.
Why this is happening?
My specs are: C2Q 9400, XFX 750i SLI, PSU 750W, Ram ddr2 800MHz 4GB, Samsung Sata HD 320 GB, OS XP SP2.
