installing new video card

Hi,
I need to install a new video card. The one I now have is onboard with only 64 megs of ram. With this the kids can't even play The Sims with all the expansion pks. I bought one today that has 128 megs of ddr. I need to know how do I uninstall the one that is onboard to use this one?
I have a K7SEM MoBo
1.5Gig AMD Processor
512 Megs of Ram
Running winxp
onboard video
Changing to:
Agp Gforce titanium Chaintech.
128ddr
It has it's own processor.

Could someone please tell me how to do this?
Thanks, Jac

 

There may be an option in the bios setup to disable it.....or you can go into device manager and check the box to disable in this hardware profile for the onboard card.......or there may be a jumper on the motherboard that you will cover to disable it.......

 

One important question I forgot to ask. Do I disable the old card before I put the new one in? I have been reading the other questions on installing video cards and it seems like people are having a problem with a black screen if the new one does not work for some reason. If something goes wrong and you have a black screen how can you see to enable the old one again? lol. I know, I'm just a tad nervous.
Thanks Jac

 

after you uninstall the on-board in your bios or in device manager.
shut down and install the new card,its not a difficult job but make sure you earth yourself to the case metal while your inside.
then windows should load and find new hardware.just walk through the steps to install the drivers.

if anything goes wrong just go back into bios and enable the old card and re-boot.
