Hello, I'm having a problem with my computer rebooting on its own. This usually happens when I am either playing a game or on the internet. The computer will just randomly reboot and I can't figure out why. I just installed Windows 7 64-bit. I checked my event viewer and I get an error message that classifies it as Event 41, Kernel-Power and says: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. I'm not sure exactly what the problem is. Please help.
