Hello, I am new to the forums, and would love to get some help from you all. So recently, my computer has been restarting itself, and I have no idea why. I have recently downloaded a game, Borderlands, from Steam, and have been playing it. The restarts started when I started playing. I've run multiple virus scans, preformed system restores, and nothing has seemed to work. I've even given my game access to my antivirus, and I've taken the computer apart and cleaned it. Any help on why it is doing this and what I can do to fix it would be much appreciated.
