Um ok, heres the thing I've had my system a little while now and well a few months ago I canged the motherboard and the graphics card the old mobo was nvidia based as was the old graphics card, the new stuff I put in is ATi based and because I found I had a conflict if drivers I look up away on the internet of how to get rid of all the old traces of nvidia drivers, so I did and I got rid of all the old nvidia stuff, but um now when I try booting up my computer it just says "Windows could not start because the following file is missing or corrupt: System32\DRIVERS\nvatabus.sys" so I deleted that one as well by the look of things.
So my question is how do I fix it?
Many thanks to all
