did you figure out a solution?
I am stuck like you. Same set up. everything was working up to 2-4 weeks ago and nothing was touched in bios. Now i am forced to use a nvidia 8600gt for now till i find a solution to this crazy situation. bios option for using only the integrated graphics is disabled/grayed out.
set up atm
i5 3570k 3rd gen
8gb hyper x kingston
240gb ssd intel 330
band aid graphics atm is nvidia 8600gt
I really just wanted to use hd 4000 for 6 months or so then ill be upgrading to a radeon 7900 series.
So other then hazenwood, does any1 else have any solutions that i can try? Thx in advance
