I have encountered a strange problem with my PC. (Spec:Intel DG 31 PR Mobo, Core2 duo proc )When I power on and press the power on switch in front of the case the computer won't boot up by itself.The only indication of the power from the PSU is a green LED on the MOBO.No fans of the CPU or PSU. Suspecting of the moisture i heated up boeard with an electric bulb for some time and all of a sudden the machine started up. But this heating is customary now.So this is not due to moisture.Now I have found out the exact place where it should be heated to start. The back left corner of the Mobo with a small ic and some capacitors. And once started this way it will work fine for hours .Help for a machine that starts by itself is anticipated.

Could be a bad solder joint. I suggest that you re-seat all RAM, cards, and cables. Unplug the computer first. The power supply could also be suspect. Take static precautions.

And if it is a bad solder joint (as OTH suggests), and re-seating cards/RAM/etc doesn't work, don't attempt repairing solder joints unless you're well-versed in such. You could make a doorstop out of the machine. Have a qualified tech look at it...
