I have had some problems regarding my Sapphire X1950 pro. The problem is that the computer works good without the Ati Drivers. (and i already tested others like; Omega And Ogn.) After i install a Videocard driver and restart my computer it gets a black screen after the Windows XP logo. (the image flashes a bit, and then the screen gets black).. I tried adjusting the Aperture size, the Resolution (in safe mode) ect... Nothing seems to work.. Yesterday i went to a friend of mine, and we tested the Vid in his computer. And again the same problem. He has a very good PSU, so that's not the problem either. The funny thing about this, is that it gets the black screen after I install a Ati Driver. Without the Drivers the computer works very good. (but no games ect).. I already did an Bios Reset, and installed Windows Xp again. I buyed this computer 3 days ago from somebody else, at his house it worked well.. But when i got at my place (other monitor) it didn't function well.. So i don't have a recieve.. Does anybody know how to solve this??... Thnx..
