I have an old computer with an Asus P4T-E motherboard. The power switch has been a problem in the past, so I added a new momentary switch to the case and connected it to the motherboard's ATX Power Switch header pins.
The computer has been working fine ever since, yet when I tried to start it a few days ago, it would no longer start after being powered off for a few months.
I've checked the switch with a multimeter, no problem there. I checked the PSU and all voltages checked out fine. The on-board LED of the motherboard is active, so the motherboard has power.
Yes, the computer is old, and yes it has already been replaced, but I still have some uses for it so I'd like to get it up and running again.
Does anybody have any suggestions as to what I should check next?
Thanks in advance!
