[SOLVED] PC not turning at all

Feb 3, 2022
My computer just kept on shutting down randomly. After turning it back on, it can either last for a while or less than a minute. I called one technician that I know of and said it said it was the motherboard that was the cause.

So I just recently changed to motherboard and formatted and reinstalled windows but after 2 hours, it shutdown again. Except this is worse that It cannot turn on at all and if it does, it tries to turn on automatically but then turns off after a few seconds.

I have a HIGH suspicion that it is the power supply because I have not change it ever since 2014 (8 years) and the motherboard i changed was only one of the problems I fixed
