My pc config -
Amd phenom 945 3.0ghz
Asus 790gx M4A8T-E
Corsair 550watts Psu
Transcend 2gb DDR3 Ram
Samsung 20" Lcd monitor
cpu suddenly turns off . To turn on my cpu again i have to reset on/off switch in psu . Again it turns off while loading windows or even while in bios . So i tried corsair 500watts psu with my another intel cpu (which was working fine) . The same problem continued with intel cpu too . Now both Amd and Intel CPUs with same issue . I have checked my ups and main power supply too. I have no idea which one is faulty - Motherboard or processor or psu ?
Help me to resolve this ....
i checked corsair psu output volt with multimeter . It seems to be fine . Moreover Amd cpu is brand new . Anyway Amd cpu motherboard , processor and psu is under warranty .
I have no idea about intel cpu . Which one is fault - motherboard or processor or psu
You do know cpu is the central processing unit, aka your processor right? In any case, I agree with the above, your power supply seems to be bad. The same power supply gives you problems in 2 different computers.
