Question How to stop computer "crashes"

Apr 30, 2020
ok so, my computer will crash at random times with random games. There are certain games that set it off everytime I play them, but every other game is fine. I don't think it has anything to do with my computer being to taxed becasue I can run demading games on High settings (The Outer Worlds for example) and play for hours fine. But the original Mass Effect game crashes on low graphics in like 2 minutes of gameplay. The weird this is it doesn't fully crash. The monitors turns off, and the backlighting on my mouse and keyboard shuts off. I also have two lights on the front of my PC, one of them that shows that the computer is on and one that shows hard drive activity. The hard Drive light will shut off with everything else, however the power light will stay on and I can hear the fans running. I have tried replacing the power supply. I have checked all my drivers, I have moved all my games onto a different hard drive and Have no idea what to do. Specs Listed Below
