Before I start, My pc will boot up fine and run games with no problem. It's not running that's the issue, the issue is when I get up from my chair or if I walk past the machine it reboots on it's own. It doesn't do it when I'm just sitting down and playing games, but as soon as I get up and walk past "boom" restarts. I've tried just about everything to resolve it. Does anyone have and ideas?
