I've tried everything, but nothing works. I've reinstalled the original drivers that came on the Gpu's disk, but it doesn't open it just says not responding. I have two HD 6770 gpu's installed, but how am i suppossed to enable crossfire with no control centre? I have looked online and found a lot of people with this problem, the majority have said its a clash between the catalyst and Microsoft.net, but i have removed .Net and still nothing, I need help please, the image below shows the only error
