I have a 98Se build with a Tualatin 1.4GHz/512MB RAM/i815 mobo, etc. Had it running with a 6800 but the card crapped out so I decided to put in a Radeon X850XT which I had lying around. However, since then nothing but problems. Could not install drivers without a crash (Catalyst 6.2), and after installing drivers CCC did not install. After installing the drivers and having the machine boot into Windows, I have weird display corruptions. For example, the mouse pointer will be corrupt when resizing windows, the little PC icon in device manager will be corrupted, etc. 3D is unusable since it's all just a garbled mess (doesn't crash though). I tried Driver Cleaner, manually installing drivers, removing all registry entries referencing ATI or Nvidia, nothing helps. System is fine in safe mode, as soon as drivers for the video card are installed it's just a mess. I put in a Radeon 9800 Pro and the same problem so I'm certain it is not a bad video card. Put in a 6800 Ultra and again no problems with this card, works without problems. At this point I really don't know what the issue is or how to fix it. So any suggestions would be helpful. Some other info about the system: it has 2x Voodoo2 in SLI, SB16, and an MPU-401 ISA card (Roland-compatible MusicQuest clone), and lastly an Adaptec 29160 U160 SCSI controller driving 1 SCSI drive. On board sound and video are disabled.
