new computer failings

[Wick3d]

I have assembled a new computer and everthing seems fine, and at first it ran for 5-10 minutes perfectly. Then it suddenly shut off, and since then it won't turn back on. if i disconnect the PSU cable or shut off the PSU then turn it back on, the lights/fans come on for about 5 seconds then die. The same happens if I disconnect my mobo from the PSU then reconect it, leading e to beleive something might be wrong with my motherboard.

any thoughts?

It sounds like your CPU may be overheating. When you attached the heatsink/fan did you use a VERY THIN coat of a good thermal compound?

Thermal compound is only supposed to fill any pits in the mating surfaces between the CPU and the heatsink. A thicker coating actually impares thermal transfer.

You didn't tell us much about your setup. If you have a newer CPU and some other things, such as a high performance video card, your power supply may be inadequate to power your system. Info, pls.

Good luck.

Umm, are those fans you're talking, are they powered via the PSU, or do they draw power from the mobo? (are the 3 pin connectors that ahve black and red wires connected to the mother board?)

powered by the mobo


edit - I have a AMD 3200+ processor, a 400 watt rosewill PSU, a 6600gt video card, and a chaintech motherboard.

Ok, try hooking up the fans into the psu and see if they run for more than 5 seconds, if they do than your mobo is fried.

Ok, so I fixed that previous prolbem (added standoffs) and now I have another one >_<.

I was fiddling around with some stuff trying to plug in a new audio thingy and i might have touched a pin with my plyers or something, and now when I turn on my PSU, all my fans and LED's and other stuff attached to the mobo won't power on, but i can't use my power switch to turn on/off power, and I can't boot. Suggestions? the mobo didn't smoke or even smell and since it's conducting electricity i don't think it's fried...

Its kinda hard to tell here if its the mobo or if its the psu.

well i'm going to return the motherboard. If it still doesn't work, i'll know it's the PSU (dont think it is).
