my desktop computer shuts off by itself. everytime i turn it on, an unusual sound from the fan at the power supply can be heard then goes normal. after working on the pc for a few minutes (15-30 max) then everything turns off. i've noticed the keyboard still lights up but the mouse isnt. i tried researching online about this issue and most of the conclusions are overheating, so i cleaned the fans on the power supply and heat sink to no avail. i also tested it while the cover of the unit is removed but it seems the fans are working fine. tried connecting the power to a direct wall still having the same issue.
can you help guys? this just started few weeks ago.
