I have a Dell Dimension 4100 866 mhz system with 256mb ram, I recently bought a Ati connect 3d radeon 9250se 128mb video card, and have had nothing but problems with it, I have taken it back to the vendor, he performed the stress tests, and ran it in another system with no problems, originally what would happen was I would play a game then it would boot me to windows and give me the vpu reovery error, then I updated...well....everything really, the video drivers, the bios, even the chipset drivers, still didn't help, then I went back to the catalyst 3.9 drivers instead of the up to date drivers, it worked for a while but then it started again, I then lowered my agp speed setting in catalyst from 4x down to 1x, now all that happens is after a while the computer will lock up or reboot during a game, and sometimes even at random times like just surfing the net, is their a compatibility issue between the Dimension 4100 and the radeon 9250se, or is my agp slot fried or something. PLEASE HELP!!!!!!!!!!
