Need to install new graphic card. How do i turn off my internal grapics card?

You should remove the CMOS battery from motherboard for 10-15 second and than put it again. When you change the graphic card, you shouldn't go to BIOS, just install the Driver for your new grapic card.

you'll probably need to update your graphic card drivers. To do so, just google your graphic card model, eg. "nvidia 9600 PCI grapic card driver download Windows XP". Also, you may check for forums that discuss games, eg. "forum YOUR GAME problem with YOUR GRAPHIC CARD" as games tend to be sketchy when it comes to graphics.

An outdated computer system would malfuntion after installing a new graphic card because is incompartible. As matter of fact, a new graphic card would card picture blank out with older model capacity computers. It is not possible to increase grapics to certain computer systems. Dos operating systems would hardly display any pixles than digits. Check on the computer compartibility operating systems, maximum graphics capacities before introducing the most updated version packs on the retails.

Hello.

The ASRock 775I45GV motherboard supports the ATI Radeon 9550 Graphic Card.

Please visit this site to download the drivers.

Please select Operating System, and model of Graphic Card.

After downloading the drivers, just run the setup program, and you will have installed the drivers (note it requires .net framework and a reboot after installation is complete)

Hope that Helps.

your power supply may be inadequate for your new card, or you forgot to uninstall the old graphix drivers before installing the new ones.

NO NO NO!
The 7900 is vastly superior to the 8500gt!
the 8500gt is a low end budget card not suitable for demanding games- return it get rid of it, that is a massive step down form the 7900. Its likegoing from a 7900 to a 7600 or worse!

Onboard graphic will be disabled automatically if there is a graphic card in AGP slot.

Try re-installing your drivers.You can re-insatll your graphics driver only if you have that option.

your grapics card is 128mb. and the most new game wont a 256mb grapics card and an avaible 1gb ram or more and your card is an onbord on you can't replace it.
