Thanks for the tip

But, to be honest, I'd rather not have to install the whole of windows just to get it to work...is there any other way I can reset to the default windows agpminiport driver without installing the whole of windows 98?
The agpminiport driver I'm using at the moment is one I've downloaded from the net, that supposedly was supposed to help any possible conflicts between geforce cards and the athlon. I've enclosed the text file that came with the driver I'm using at the mo if it helps.
But, as I said, if anyone knows a way to reinstall that default windows agpminiport driver, or knows where I could download one from the net that'd work with sacrifice, I'd be incredibly greatful. Thanks again.
