I am experiencing a weird problem with my ATI Radeon HD4870 1GB card. I had the original drivers in place (vers 8.12) since I bought my PC, an i7 940 with an Asus motherboard, 4GB RAM, Windows XP SP3 Home 32bits).
I downloaded and installed the latest CCC and drivers (vers. 12.6) after uninstalling the old ones. Everything worked fine except that I lost the 3D acceleration and in DXDiag, it could not be reactivated.
I uninstalled the new drivers and CCC, cleaned up any remaining files in safe mode, rebooted and installed the original drivers from the CD, then CCC would not open, whatever I tried, searching days on Internet, everything failed, but according to DXDiag... my 3D acceleration was back!!!
I uninstalled the original drivers and CCC, cleaned up again in Safe mode, restarted and installed the 12-6 back, no 3D acceleration available in DXDiag again.
Among many other things I followed the recommendations available on one of your thread to no avail. So I now find myself with a no win situation, either CCC does not start and can't be used or I have no 3D acceleration.
Would anyone please share any advice to unlock this? Any feedback would be greatly appreciated.
