Crashing while playing games, Kernel Event ID 41 Task Category 63

I need a little help with a problem that I've had occur for the past few days. So I would try to load up a game and play, but in doing so, my computer will go into a black screen and restart itself once I start actually getting into the game. No BSOD is shown. I checked my event viewer and found out that I'm getting this critical error of "Kernel Power Event ID 41 Task Category (63)" and have been working for hours trying to find a solution. Drivers have been reinstalled, tested my RAM, checked the hard drives, and voltages have looked fine on my PSU. The only things I haven't checked are testing my GPU and CPU, so does that mean either of those components could be the source of these errors? or is there something else that I'm missing here?

Here are the critical error properties:
