I build a Sandy Bridge hackintosh some month ago with components listed at tonymacx86 and everything worked nicely like a real mac.
I used the onChip Intel HD3000 Graphics so far.
Now I upgraded to a PowerColor Radeon HD 6870 1GB.
System boots well, playing games works also without any problems.
But when I surf the web, I get a black screen after about 10 minutes and I have to reset the Hackintosh to reboot.
I tried several AtiConfig Framebuffers, but nothing solves the problem.
As I saw that some users got this card working OOB, I dunno what I'm doing wrong.
I also installed Windows, no issues there.
Does anybody have an idea what causes this problem?
Thanks in advance!
