Bad PSU or Mobo

[goonx]

Hey guys,

First off, i have an amd athlon 64 4400+, A8N-SLI premium and lastly an antec truepower 550W PSU.

Here are my symptoms:
Computer runs fine, boots into vista. Works great. However, periodically it would just "die". It won't turn on after pressing the power button multiple times and even when i d/c the computer from the wall outlet. The mobo LED light is on whenever this happens but nothing else responds, no fans, no HDD. After a while, the computer powers on after I press the power switch. Works perfectly normal for a while and then dies again. It's like a cycle.


I have tested the ram, and CPU. I've even got a voltmeter to measure the power rails of the supply by shorting-out the green wire (power wire). Cleared the CMOS.

Anyone know if it's the power or the mobo that's going faulty?

Sounds like a PSU problem to me. When I had PSU issues, the computer would just die without warning, and having to wait for the computer to want to turn on also seems like a PSU issue. If there's a problem with the board the fans should still keep going if they're connected directly to the PSU.

Do you have another PC to test it in?

Yes it is a PSU problem. Get a new PSU.
