Really no idea what i am doing wrong, so desperate for help atm.... Ok what i did today... Get my replacement card from the shop. Instead of the Sapphire OC edition i got an XFX 5970 Black Edition. As my card was in repair for a few weeks i replaced my cards with an 8800GT. Step 1: Remove NVidia driver Step 2: Replace 8800gt for 5970 Step 3: Going safe mode and use drivercleaner - then registry cleaner. Step 4: Install Catalyst 10.5 - 10.7(hotfix) - 10.8 beta. but neither of them work. It keeps asking for the inf file. What seem to work a bit is going to Properties - Device Manager and manuially install driver. But then Vantage tells me my card is no capable of playing DX10, and in AoC it will not start in DX10. Strange thing is Heaven Benchmark works in Dx9-10 and 11. I so want my card to work correct. but no idea what i done wrong or what to do to set thing right again. thx in advance.
