power button = nothing

[Homerboy]

Buddy has a PC that when you hit the power button, nothing happens. Nothing at all. No fans. No power to anything.
Swapped out the PSU. Still nothing.

Motherboard toast?
Just a bad "power switch" maybe? Sadly this is an e-machine hunk, and 90% of the case is riveted shut.

Amazingly, I;ve never run into such a problem before.

Any suggestions?

Try shorting the two power pins on the mobo where the switch plugs into. That'll let you know if the button is toast.

If that is not the prob, change the PSU

I have the same problem.

I am bulding a PC. I have a brand new mobo, cpu, and case.
I installed the mobo, cpu, heatsinc, and fan.
I connected the 20pin and 4pin power connections to the mobo.
I connected the cpu fan and a second fan. A third fan connections on the mobo isn't being used.
The PSU is on 115 volts.
I turn on the PSU and a green light comes on the mobo.

When I hit the power switch, nothing happens. I even tried using a power switch from a computer that I know should work and still nothing.

Please help!!! Thanks.

mulder - change psu I think.
Especially if its the psu that came in a cheap case

Any risk in just plugging in a new PSU without actually installing it in the case for testing purposes?

I think it is best to install it in the case for the purpose of earthing it, or at least earthing the case.

Its only 4 screws
