[SOLVED] PC fans start spinning at full speed, screens black out.

So, for a bit of backstory, this computer never did this after first building it. It wasn't until recently, maybe 1-2 weeks ago, that it started doing all this. At complete random, my computer will black out and have the fans run at full speed. Almost every time after restarting, I check the event viewer, but no errors are displayed.

I've done the following:
Updated GPU drivers
Updated OS
Updated chipset drivers
Uninstalled suspected software (which ended up having no effect on my PC in the first place)
Installed antivirus, scanned PC (found nothing)

I have yet to check the actual hardware of my PC. And, speaking of, my specs:

CPU - AMD Ryzen 5 5600X 6-Core Processor 3.70 GHz
RAM - Ripjaws 128 GB [4 sticks]
MB - Aorus B550 Elite AX V2
GPU - Gigabyte RTX 3060
PSU - Cooler Master MWE Gold 1050 V2 1050W
OS - Windows 10

EDIT: I don't know what fixed it, but I've updated a few other things, and replaced the thermal paste on the GPU. It works fine now.
