PC Won't Immediately Turn On After Normal Shutdown.
i shut down my pc properly, within a minute i try to power on again, but cannot turn on. Fan not moving, no lights no beep sounds at all. i unplug the cables around the PSU, and plug it back, it works.

what is wrong with my computer?

It looks like your power cables are loose. See if it happens again, if so. Your power supply might be failing soon.

yeap power supply might be dying. had it happen before. wouldnt turn on a few times. had to unplug and replug the psu cable a few times. as time went by, had to unplug and replug even more times. eventually, it stopped turning on at all.

i just tried again, i got to replug and plug the cables and the power cable a few times then can turn on. need to try about 5 to10 minutes or so to turn on.

so just now i leave my computer untouched for 2 hours, it can turn on immediately. So confirm is power supply dying?
