Hello. I have a Dimension 1100 with the motherboard built in Intel Graphics card. I've bought a Club 3D ATI Radeon card (PCI) with 128 Mb memory to upgrade. I've put it in one of the PCI slots, attached the monitor cable to the new card and started the system up and the monitor goes black. If I switch monitor cable to the original motherboard graphics card everything's OK. Anybody have a clue what the problem might be? I've gone into BIOS and checked the graphics setting to be on Auto. I've also tried with another card (A Rage II 3D) and this works fine. Could it simply be that the new card is not working, or have I missed something out?
