Hello. I've been having this problem 2 days already. I changed my MotherBoard and CPU only. Installed Asus PK5C MotherBoard with Core 2 Duo E8200... I left everything else intact. The Graphics Card is the same - Pretty Old - Nvidia Geforce 6600 and RAMs too. One is 512 MB and the other stick is 1 GB. I connected everything well, reinstalled windows XP and it worked for 30 mins probably. Then it started automatically restarting... And it does even now. I tried ALMOST ABSOLUTELY EVERYTHING I could do.
I had the Power Supply 350W. But I changed it and installed another 350W supply. Still the Same.
I've tried every combination with RAMs. --------- Still the same
Nothing works... It just restarts randomly. I don't even know what to do. And the previous motherboard and cpu I had, worked fine ( 3.0 ghz intep pentium and 775xfire-VSTA ) .
Had antivirus nothing, removed, still the same...
I'm so confused I don't even know what to do.
My only hope in this thing goes to you goes. You gotta help me out. I've searched everything in the net but nothing helps.
