They just keep coming back!!!!!!

[error41]

I switched video cards from an ATI to an Nvidia. I uninstalled the drivers from ati because I realised they would cause conflict when initiating certain games. However, the conflict was still there. I found some ati .dll files in WINDOWS/system32 that were linked to ati. I deleted them, but when I went back to system32, the little buggars just came back. Does anyone know a way to permantly exterminate these .dll files, cause it is conflicting with Nvidia stuff.

there may be some temporary installation files somewhere, try searching your drive for .tmp files. have a look at what they are from and delete them if associated with Ati

You might have some luck using the ATI Catalyst Driver Uninstaller:

Here's a link to it:

It was made by ATI, so it's also available from ATI's website.

I could not find any .tmp files linking to ATI. I had tried that before, still no luck. The Catalyst uninstaller was already used before, again, still no luck.

have you got the Nvidia card installed? if you have onboard graphics try removing the Nvidia and deleting the drivers then use drivercleaner.
