Issue #1: My Hackintosh keeps rebooting randomly without any other information, all I get is a message when I get back to my mac saying that the PC has shutdown unexpectedly, also the American Megatrends error shows up when booting...

Issue #2: When I shutdown my mac it does not shut down, it reboots, and also showes the American Megatrends error.
