[SOLVED] PC randomly shuts off and can't turn back on unless I replug the power supply back in.

[MyDude321]

I don't understand why does my computer randomly shuts off (a lot more recently) and won't turn back on unless I replug the power supply from the computer? It's not overheating, my GPU stays around 70 degrees celsius.

Specs:
AMD Ryzen 7 3700x
Nvidia RTX 2070 super
MSI x570 gaming plus motherboard
Inwin PB-750w power supply
Fractal Design Meshify C

I need help !!!!

Sounds like a power supply issue. Is anything overclocked? If it is set it to stock speeds. Also can try a motherboard BIOS reset, unplug system, remove the CMOS battery and hold in the power button for about 15 seconds. Plug things back in see if it works better. If it still does the shut off, try another power supply. Corsair CX is probably the cheapest good quality one.

My GPU is overclocked, is that an issue?

Yes, never trouble-shoot overclocked systems, need to run everything at stock speeds or you are just adding more variables in.
