I've been having a strange problem for the past few days. In the morning when I try to turn on the computer by pressing the power button nothing happens. I've found that if I unplug the cord from the computer then plug it back in the power button will then work. Once the computer is on everything appears to be fine but I have the same issue the next morning. Anybody know what it might be?

Prelude to M/B or P/S failure possibly.

Diagnosing is a process of elimination, eliminate whats known working as a possible problem, and whats left is the problem.

If the case power switch was bad pulling the power and reconnecting it wouldn't do a thing it still wouldn't power up.

In some situations the M/B defaults to default settings if the power is pulled this is basically a built in OCing plus, have you gotten a CMOS Checksum error on bootup at all?

You could try replacing the CMOS battery with a new one, and eliminating that as a possibility.
