I have Dell Dimension 9100, running Windows XP. I replaced the OEM Video card with a ATI Radeon B2 3650 1GB PCIE card. I also just added a Microsoft LifeCam VX5000, while the cam will work for Live Messenger, when trying to use the "MicroSoft Live Cam" program it indicates there is no Camera installed on this computer. It appears that the Display Approx. Total Memory is not enough, the LifeCam info says it requires at least 2M Video memory, it shows 1024 using "dxdiag" from "setup" - "run" in the "Display" tab. Is there a way to increase the display Approx. Total memory in the system/system BIOS? Or what do I have wrong here?
