PC not powering up
 

My stepdad's PC starting acting up, in that it doesn't power up when you push the power button. I figured it was a bad power supply, but the green LED on the motherboard still lights up, and the tiny plugs for the power switch running from the case to the motherboard are still intact.

Anyone have any ideas on this one?

dirty contacts on the switch, maybe?

Try attaching the reset button to the power header. If that doesn't work you're most probably looking at a faulty power supply, as you first suspected.

Though there is something to be said for checking the power cables attached to the motherboard haven't come loose.

I tried all those, but in the end, the problem was the power supply itself. It just threw me off that the MB LED was still going. I was always under the impression that power supplies either worked or didn't work, with nothing in between.
