psu or mobo?

post #1 of 7
Thread Starter 
hello guys
sorry about my bad english i dont have time to correct it, just need a quick reply.
so the problem goes like this:
when i hit the power button on my case the system powers for about two or three seconds and goes off.
I hear no beep and see no display, nothing.
I tried to disconnect everything except the 24 mobo cable, still the same,
until now i was sure the psu is the problem, but when i tried the green+black cable method with only one fan hooked, the psu did not shut down.
now i dont know what even to think
unfortunately I dont have another system to test the psu there.
so what you think?psu or mother?

You checked to make sure the board isn't touching anything that could short it out?

Also, do you have the 8 pin EPS cable connected to the MB along with the 24 pin?

Have you tried reseating the CPU and the RAM? Maybe try just 1 stick to start? It could still be the PSU failing under load.

Hmm...I'm not sure, but from what I understand, when it goes through POST, it tests each component, so if you're CPU or RAM is "bad", it won't go past that point. I do know that on my board, it has LED's for each, and if it has a problem with a particular part, that LED will remain lit while it tests it.

I connected the 24 cable only, and tested two different CPUs, both fail.
when I run with no cpu at all, the psu keeps run.
so I assume I need a new board?
