I recently upgraded my video card and took my old card and put it in my spare computer. My old card is an ATI 9800 Pro. I installed it into an emachines computer with a 2800+ AMD Athlon processor, 160 GB hard drive and 1 GB of RAM. Now I can't run certain games, like Company of Heros, Civilization4 and the like. For some reason I can run FH2 on occasion. A message will pop up that the rendering device couldn't format, that it is an error that occured due to wrong direct x version. Well we installed the newest one for direct X 9 and the same error still occurs. That and FH2 uses the latest version and will run when nothing else will. We have tried adjusting settings in smartgart and the regular settings with no luck. When the video card was in my Dell it had no problems with the same games I have issues with now. That and before I installed the 9800 Pro in my emachines the geforce pci card that we installed at the beginning worked fine with these games other than they were a lag fest. That was the reason for installing the 9800 Pro, hoping the games would run a little smoother. Does anyone have any ideas on what I could do to get things to work? Any help is most appreciated.
