Randomly computer shut down

[Cold123]

Recently my computer has been randomly shutting down. There is no error screens, no messages, it just instantly turns off. Im positive it isnt overheating....im all out of ideas. anyone know what is wrong?

PSU, drivers, conflict of internal resources????

Could be any of those three.

House power wiring issues is one of the first things I would suspect.

Get a tester, their a few bucks at a store. Like a home depot or lowes.

to the 2nd reply, its not a reboot, its just everything turning off, i have to switch the little on switch on the back of the case off for a few seconds and then back on in order for the computer to turn back on. And its only been recently that this has been happening, and i havent installed any new software or hardware.
