Question Computer not turning on after few months of sitting.

[couchpotato]

I tested the psu and it does turn on but the computer itself won't turn on. I checked the wiring, the psu on/off switch, and even I tried jumping the power switch pin and get nothing, it's completely silent. This is one of my older set up that I've had for a while so I was wondering, if the motherboard was indeed dead would there be physical signs? I've used it a few months back with no problems.

Update your post to include full system hardware specs and OS.

Did you try replacing the CMOS battery?

As for the PSU you can do some testing beyond just turning on:

If necessary get help from a knowledgeable family member or friend to help with the multimeter.
