computer dies after 1/2 second

ShaqDiesel · 08-19-2006, 04:03 PM

When I turn my computer on, the fans and lights turn on for 1/2 a second and then dies out. What's the problem?, MOBO, CPU, PSU, etc? I'd like to narrow the problem down but dont have spare parts; Thanks.

Here are my specs:
DFI nF4 Ultra Infinity MOBO
amd64 3000+ cpu venice core
Antec True Power 2.0 550W PSU
XFX geforce 6600gt video card

I had a computer that would do that once. If I remember correctly it was the motherboard in that one, but I suppose there could be a number of things wrong with it, I'd check the PSU as well.

I'd test the PSU, but I agree with Oxagast in that it sounds like a board problem.

Have you made any changes to the system? Only time Ive seen that is incorrectly installed hardware, like screwing the MB directly to the case with no standoffs(friend of mine did that, shorted the PSU). It sounds to me like a hardware problem. Try striping parts off and look for when it starts working. RAM, video card, hdd, fdd, even cpu, with nothing but the MB it should atleast stay running and just yell at you.
But like i said, something is shorting the PSU most likely.

Almost certainly the power supply, although it could easily be your motherboard, processor, or RAM. Check those by swapping in known good parts.
