My system currently has a (Cheap Brand xTreme Gear PSU) 500W PSU With 550ti Graphics and a AMD Athlon ii X2 at 3.2GHZ. Whenever I play any PC games, even something as simple as Minecraft, will freeze. Whenever I play a Steam game and after awhile something in my PC makes somewhat of a dying noise, like a fan turning off or something, and 30 sec after that happens the game freezes and I need to do a hard reboot. Is the CPU the issue? Does anyone know what the noise might be? Thanks.
