Hi guys You may remember that I got myself a pretty 9800 Pro a couple of weeks ago. I then decided to replace the GF2 MX in the PC of my girlfriend by the one I had before in my PC, a Radeon 8500. In my PC it worked absolutely without any trouble. The GF2 MX worked fine in her PC also. Now that I have pu the 8500 in her PC, it won't work any more. She has a *cough*Packard Bell*cough* computer which is not that bad ( Athlon XP 1600+ ). If I use the 4.7 or 4.6 catalyst drivers, I can't even go past the XP loading screen. After it switches to the resolution I have set (1280x1024 on a 19" monitor), it goes black with some color pixels scattered there and everywhere. What I don't understand is that I also have the same monitor and was using the same resolution on my PC without any trouble, but I had 2000, not XP. I tried to install the 4.5 cats also. With those I can boot up, but eventually after like 20 minutes the VPU recover thing says the GPU has crashed and the display is switching to software and 16 bits. I also tried to do a clean XP install (new HDD) and it's absolutely the same. I have no clue of what I can do with that stuff .... Try alternate drivers ? (DNA, others ?) Some other ideas ?
