so i have a late 2012 slim imac with the 27 inch screen and a nvidia 680mx card in,
when i update the graphics driver on windows 8 it installs ok, but thinks there are two displays when finished, and the screen is extended onto screen 2 but when i restart it will not boot, windows boots but then the screen is black but lit and then the screen changes brightness and then restarts, the mac statup noise is really tinny then and it will fail to boot again, when i restart once more the startup sound is back to its normal boom but then goes into windows 8 recovery options as it failed three times.
any help would be brilliant
