Hey computer friends,

My PC won’t turn on anymore. It was running okay, and then I told it to go into standby. Well, it didn’t go into standby — it just shut off.

This had happened once before, and I just needed to fully cycle through the power (unplug, replug) for it to work again. But now nothing works.

After a lot of trial and error, I see that the green LED on the back of the power supply only comes on when I have the supply disconnected from the motherboard. As soon as I connect the 24-pin connector from the PSU to the motherboard, this LED goes off.

Random Google searches talk about issues with standby power … or stored static charge. Pretty sure I’ve gotten rid of any excess static from all the fumbling around I’ve done, removing modems and video cards and detaching/reattaching RAM, etc. But it seems the motherboard won’t accept the PSU anymore?
