Video Drivers are not keyed to the system. It's the video card that needs the drivers. You should have run the Windows Upgrade Advisor first and you would have been told that the Dim 1100 is not a good candidate for Vista Ultimate, especially if you have integrated video. Integrated video cannot run anything but the Basic version. And does that poorly. Consider returning to XP.

Mary, Instead of shutting the door on the OP you could at least give them their options before chalking-up another post. BTW: video drivers can be found other places besides Dell if you didn't get the card from Dell.

 

hasnain721,

If you have an available PCI slot you could use a PCI video card. Not the greatest, but better than you have. Here's a link to some:

kpo suggestion is really good, but In my opinion you may get a poor Vista experience...

so basically ur advice is to upgrade right as there is no other alternative.

I mean, a new computer, with the Ultimate requirements will be better, than upgrade that system...
