I check temprature so idle temprature is about 18-19C and load about 31-32C.
Whenever I try to run performance stability test from ntune, after couple of seconds, my PC suddenly hang up, and after few seconds my monitor screen goes black.
I try the same test before on my old Pentium D 3.0GHZ, Abit SG-95 Motherboard using same PSU and Same GPU and that time also it hang up. I had Win XP Pro that time.
So guyz, what is the main problem? Is this PSU or something else?
Thanks in advance,
