Black Screen/Hibernation #GPU



I have a Hackingtosch build using the GA-Z77-DS3H Motherboard with onboard Intel Graphics.







the machine boots no problem, and other than having to do a input search from my LG Monitor on first boot the machine runs fine for 1,2 ,maybe more days.







Then all I see is a black screen and no amount of keyboard or mouse clicks will wake it up.







Only a Hard Reset and reboot will return it to normal.







It seems as it the machine goes into hibernation/sleep (I have set it never to hibernate), however I have put the machine into sleep mode from the apple menu, and was then able to wake it up with a keyboard press or mouse click.







Any help would be much appreciated.







Regards
