This is my situation. I was using the Radeon 9550 until it overheated and suffered from Graphical Artifacting. I then came into possession of a new variant of the exact same card, the Radeon 9550, except with a fan instead of a heatsink. Now my problem is that my computer crashes at a very bizarre pattern (can crash once in 5 hours, after that, 5 times in 30 minutes) with this card installed. After the crashes, alot of the time I had to reinstall the drivers, and after the crashes it would state that the drivers were the root of the problem. I've reinstalled many of my drivers, including the Omega drivers for the card at www.omegadrivers.net, and with that driver the card lasted for a very long time before freezing and crashing (granted, the installation did seem to hang for a bit, so I had to cancel it, however it said that the installation was complete when I did this). I don't know the make or the specs of my mobo, but the GFX card is AGP 8x. Thank you so much if you can help me, I really want to get back to my normal gaming life. Thanks in advance, John.
