I installed a Radeon 4650 AGP but it hangs when playing Call of Duty, even if I set the game to run in 640x480!!! My onboard graphics is an Intel 82865G which stopped working normally. I uninstalled the driver for this but don't know if this card could be interrupting the Radeon? Don't know what to do as I don't know how to disable the on board card completely. Please help!
