After I shut down my computer it automatically starts up again. I've tried re-installing Windows 7 64-bit, resetting my BIOS, installing the newest drivers and also changing the boot and recovery settings.
The motherboard I have is a MSI P67A-GD65 (B3), and the processor is a Intel Core i7-2600K.
How can I shut down my computer and have it stay off? Also, what is causing it to immediately boot back up?
