Greetings all, I am helping my step-uncle build a new computer. We got everything put together, turn on the computer, the computer will boot up and then within 2 minutes will just shut off. The most it has stayed on is 5 minutes before it would shut it self off. The computer doesnt even have an OS on it yet. System Specs: AMD Athlon Xp 3200 DFI NFII Ultra B Motherboard Diamond Stealth S100 - Radeon 9600SE 128mb Vid Card 1024gb PC 3200 Ram Creative Blaster V.92 Modem Emprex 8x DVD RW Western Digital 120gb harddrive Raidmax 420w PSU There are no errors or any warning. It just powers down. Any help you guys can offer will be much appreciated. Thanks.
