1. Make sure the thermal grease is applied correctly and the heatsink and processor are attached as designed.
2. Swap in a known good power supply.. Although you're current one may be new, it appears like it could be the culprit.
Hope this helps.
onboard graphics card, but if computer didn?t boot I was going to try using [BFG Tech]GEFORCE 7950 GT OC
AMD Athlon II quad core
4 x 1gb DDR2
650W blustar PSU
*Everything is new, the only thing that is used is the graphics card*
I just put together this new computer. I haven't even put an OS in it yet. I turned on the computer and everything was working so smoothly for about 30 minutes, then out of nowhere it turned off. When I tried turning it back on the fans and led lights would turn on for about 1-2 seconds then shuts off (so basically everything turns on then off within seconds) it won?t stay on, however when I have the PSU on the little green LED light on my motherboard stays on and as soon as I turn off the PSU the motherboard's LED light will go out so I don't think it's the motherboard but I could be wrong. Everything is compatible with the motherboard I've checked thoroughly. I also took the motherboard out of the case and looked for any dark marks I also smelled it, and see no signs of the motherboard being burned out. I double checked all wiring and hardware components and tried it, still the same.
UPDATE:I tried turning it back on but the fans and led lights are not turning on at all.but the little green LED on the motherboard is still working fine. HELP PLEASE .
Any help will be greatly appreciated
