I'm trying to put in a vid card in a pc that has a vid card attached to the mobo, do I have to disable the built in vid card before installing a new pci vid card?

I would think you should pop in the new one, turn on the computer, disable the integrated one, set it to the new one and work away!!!!

I'll look to see if I can disable it then

okay, let me try this again. I just popped it in and it didn't take so I wasn't sure if I had to disable it. It just hung for a while and even when I took it out it hung, but it's an ooollllldddddd pc so eh, I'll find out
