    My computer will completely shut down, no warning, and completely randomly. It does this extremely frequently and I don't know why. I don't know where else to ask this but I'm getting tired of it.

    A couple of possibilities: it could be a failing power supply unit, or the PC is too hot and turning itself off to prevent damage.

    Well it's definitely not too hot bc my room is really cold so I guess it's the power supply. Weird thing is tho is that the monitor shuts off first and the computer itself follows like a couple minutes after

    When you say the monitor shuts off first, does the screen say lost signal or does it power off with no led lights?

    a overheating computer would be more likely to do with... lack of fans intake and exhaust/old thermal paste/poor heatsink contact on cpu ....etc

    So if the monitor says lost signal, then it didn't really power off. That is the graphics card giving up. Replay is right. Check the things he said.
