Hi all,

I have two computers with A7N8X motherboards and Aopen 350 watt power
supplies.

One of these computers will not power back up with the power on button
after I have done a Windows shutdown. It seems it needs to cool down.
Sometimes even after being turned off over night in air conditioning it
still will not power up unless I turn off the power supply for a while.

I have checked the motherboard connections and they are good.

Any ideas from the group?

Try swapping the PSUs - if the fault moves to the other PC, then
you've found the culprit. If not, unplug the soft-on front panel
switch from the mobo on the 'bad' PC and use a small screwdriver to
short the two pins after you have shut it down - if it powers-up ok,
then the power-on switch is probably faulty (I've seen this a couple
of times on different cases.)
HTH
