Assetto Corsa (and ACC for that matter) randomly makes my computer shut off

When I boot an AC race, I get to drive for like 2 minutes and then my computer just shuts off. My GPU drivers are all up to date and I'm pretty sure I don't have any windows updates to do. This started happening after I added an old drive to my computer a couple months back. I have since removed that drive since I was getting a lot of problems from it. ACC has always had these problems since I downloaded it, and I also get "The UE4-AC2 game has crashed" notifications. Does anyone have a fix? Thank you!

... PSU too weak? Voltage spiking that causes the main board to shut down?

Thats the first thing I would consider, PSU problems.

Ive had this happen.

Thanks! I think I might have dislodged a cable or two when I was putting in those drives. I'll give it a shot, thank you!
