If I play games for a while mu computer starts to crash. I will either get the BSoD or my computer will lock up. Both times i need to hold down the power button to turn off the computer. If I don't play video games for a long period of time (for a day or 2, maybe) my computer will run video games just fine for a while, then the crashes become progressively worse. This happens only for video games and nothing else. Even small games like Minecraft crash the computer. It usually crashes within 5 minutes of playing, and there's no warning its just a sudden crash.
I have a Dell XPS 8300 (I got it back in 2011)
Intel(R) Core(TM) i7-2600 CPU @ 3.40 GHz 3.40 GHz
12.0 GB RAM
64-bit Operating System
My graphics card is a nvidia geforce gtx 650 ti, but the fan is broken and vibrates. I do know that one time my computer crashed while I was playing COD and my GPU was about 60 degrees Celcius.
