PC shutting down when attempting to play games

[AEJ14170]

Basically, normal use is fine, but when loading a map in a game (I can load the actual game fine, its just when I go into a match) the PC's fans spin up pretty drastically and violent, and the display cuts off and the PC turns off.

We need to know the system specs. You might have too weak of a PSU for the card.

That would be a possibility, except for the fact that I *did* mention that the PC worked before, until I made those changes.
