New Replacement MoBo problem

Last response: in Systems

A friend brought me his computer because it wouldn't boot.
After inspection, I found a ruptured capacitor on the motherboard.
He purchased a new Foxconn, M61PMV to replace his old ABit.

After clearing out the case I installed the new motherboard, CPU and HSF,
Outside of the case, and all I got was the HSF spins for about 7 seconds and
then the system shuts down. To get it to start again I have to unplug the PSU
and wait about 5 minutes, then when I plug it back in I get the same results.

I have tried it in the case with the same results.

Nothing but the HSF and PSU is connected.
I have gone over all the tips at
to no avail.
I have swapped out the PSU for a different one, with the same results,
and I have tested the PSU for correct voltages.

I am assuming at this point it is likely the motherboard, however I do not
have another CPU to test with.

Any help would be appreciated.

You could try unplugging the power switch header and starting the PC manually... I once had a faulty power switch cause me a lot of trouble lol.

Other than that, it sounds like a mobo to me.

Honestly I did not think of trying that.

I will try it now and post back results.

TY for your quick reply

You are a gentleman and a scholar!

It was the power switch. I shorted the jumper and
it booted right up. So I added a old switch and
voila boot success.

I thank you!!
