NO signal on monitor after installing new graphic card

[djm130]

Hello,

I currently have a GeForce6100PM-M2 motherboard with an onboard graphic card. I bought a new XFX Radeon 6670 graphic card in order to play Diablo 3. However, I tried to disabled the onboard graphic card and place the graphic card in the mobo with the monitor plugged into the new graphic card and there was no signal. I took the new graphic card out and plugged the monitor back into the onboard graphic card and the computer booted fine. I then enabled the onboard graphic card and turned off the computer. I installed the new graphic card in the mobo again and plugged the monitor into the new graphic card and again no signal on the monitor. I plugged the monitor into the onboard graphic card while the new graphic card was in place and I could hear the computer booting up but there was no picture. Do I need to install the drivers for the new graphic card before I actually turn the computer off and place the card in the mobo.

with nvidia based mb with there built in video chipset they dont like ati cards. you have to use a nvidia card with that mb. so that the mb think your going to sli the cards.
