Specs: Windows 7, amd athlon 64 x2/4GB crucial
alright, comp died one night, took it to get a diagnostic, the guys at the shop said it was the psu/mobo, both were fried, i said fine, went ahead and bought a new mobo, and psu, put em in,it was fine at first, was prolly 2 hours into messin around on my comp and it died...i figured overheating, i put a huge box fan on it and it continued to die...when i got up in the morning it wouldnt turn on at all, eventually it started,cuting on then instantly off soo i started to remove parts and see what might be the problem.

i took out my disk drive and it started up and came to life, stayed on for a while...till i tried to plug my keyboard in the rear usb drives..instantly it shut down., from there its back to the ol, come on and die stuff.

i was getting one beep, which if im not mistaken means post ran fine.
i took a multimeter to my 24 pin connector and found all had the proper voltage and the grounds where all zero, so im sure its not my psu. now i didnt put any new thermal compound on when i put the CPU on the new Mobo, i'v been told multiple times that may be the problem, but surely that cant be it.

specs:
amd athlong 64 x2
msi Mobo
581W Psu
geforce 9800GT
genericn Hdd
theres 4 fans not counting the PSU/heatsink/V-card.so i really doubt overheating is the problem, i'v tried in many different outlets thinking maybe its a bad recepticle..its not that either...i'v about exahusted all options, and i'd hate to have to go to some overpriced computer store to get this fixed.

ty in advance.

oh ya, the less i have plugged in the longer it seems to stay on(still only 5-6 seconds at best, vs 1-2 seconds with everything plugged in.) seems like theres maybe a short somewhere.

You appear to have forgotten to mention the make of PSU and the voltage/amps. Or in other words is it up to the task

Always when swapping CPU's you should clean of old paste on both CPU & Heatsink and re-apply.

"i didnt put any new thermal compound on when i put the CPU on the new Mobo"

That is absolutely your problem, no question about it. Here's the application instructions:

the PSU is a coolmax CL600B


3.3V**+5V***+12V1**+12v2***+12v3***-12v***+5vsb
24A***24A***18A******18A******15A***0.5*** 2.5A

astrics for spacing purposes, and i put on thermal compound and let it sit, it's still acting up.

You need to follow the instructions exactly. All traces of old compound must be completely removed, then both surfaces (top of CPU, bottom of heatsink) must be cleaned with a solvent (alcohol or acetone). Once cleaned, the surfaces should NOT be touched...fingerprints can adversely affect heat transfer. The bottom of the heatsink should be "tinted" , then a single dab of paste about the size of a BB or grain of rice should be placed in the center of the CPU. At this point, the heatsink should be installed & locked down. The heatsink should then be twisted very slightly clockwise & counterclockwise to seat it. That's it. If you did it any differently, you did it incorrectly.
