hello i have recently purchased a Geforce 8400 gs pci 512mb ddr2 graphics card and i have a emchines computer with windows vista and ive done everything that it says i disabled the internal one in device manager under display drivers but after i install the new one into the pci spot and install everything on the computer and retart everything and go back to device manager it doesnt read it like it doesnt display my new one it still says the old graphics card and i have it hooked up to the new graphics card and everything but i was just wondering if i missed something? would appreciate it if had a fast reply because its been 2 days trying to figure it out and its very very frustrating.
