Question : Problem: Installed new pci ATI card for duel monitors and original card no longer works

Trying to install duel monitors on xp pro.  I installed a Diamond s60 32 MB Radeon 7000 pci video card and it works fine but the original ATI Radeon xpress 1100 card no longer starts.  I tried updating the driver of the original card with no luck. What do I need to do in order to get both cards to run for both monitors?

What is the motherboard model?Is the 1100 an onboard video or is it a card in a PCI x slot??
If its onboard then you need to look in the BIOS for settings to see if both can be enabled.
If its a card in a slot then you also need to look in the BIOS to make sure its the primary adapter for video.
