My computer is restarting whenver I play games. I took it to a shop and they ran it overnight with a benchmark program and it never overheated or restarted. I have uninstalled my current drivers and reinstalled older ones that worked in the past, and I am still having issues. My first though is heating issues, but as far as I can tell the card hasn't been overheating. I also don't see a pattern in what games are causing the restarts. Fallout New Vegas, Far Cry 3, Pay Day 2, all of them.
