[trying2makeitwork]

I installed a Raedon HD 4350 LP graphic card in my slimline 3120 but the drive never loads. Anyone have any sugguestions?

What do you mean by the drive never loads?

I suppose you could get a low profile card in there if your power supply could handle it. If you know the rest of your specs and the wattage on your power supply that might help.

I look at system info and don't see the driver loaded.

The card was detected by the setup software and loaded Catalyst install/info manager. But when I rebooted the system as I was told my system still doesn't see the adapter. The $64k question I have is do I have to unistall the NVIdia intergrated video controller first for my system to see the new graphic card? And If i do so will the system still have some sort of default display controlibility?
