ATI DRIVER PROBLEM

For one reason or another I had to reformat my computer... this led to re-intalling winXP... that's all well and good, then it tells me there is a problem with my ATI driver and I should re-install my display adapter; I find my disks and give it a shot... it's now telling me I should set up my display adapter with a "Standard VGA Driver" and then re-run the setup for my ATI Adapter...
So basically I need to find a "Standard VGA Driver." Anyone know where I can find one of these???
