First boot AGAIN!!!!

[danman2005]

I want to take this computer and throw it off my roof. Well now that I feel a litte better, here is the problem. The computer will boot and begin to perform it's pre-os system check. Sometimes it makes it all the way through, and some times the computer turns off. If it makes it all the way through, the computer will turn off shortly after. Without a doubt my CPU works and ram. The problem must be in the motherboard or the PSU. I've tested the system outside of the case with the same results, and with another PSU. Now the problem is the PSU's came with cases for free ( I know they aren't good but the person I'm building this computer for has a low budget). One of the PSU is 500W and the motherboard is a 865PE-TAG. Do you guys think it is the cheap PSU or the motherboard?

Thanks,
Danman

Since you tried a different PSU, check to make sure that the CPU heatsink is fully latched on and is in the correct position.

What specific PSUs are they. Do you have a 4 pin cpu auxillary power connector on the motherboard? If so, is it plugged in?

Or rather can you post your full sys specs with the PSU brand/make?

It turns out that the heatsink was not in full contact with the processor. I fixed that and now the computer is up and running. You guys are the best. Thanks
