How to Remove all Trace of Old Hardware and Its Driver?

[farquea]

I need to completely remove all trace of a pci device as i suspect its lingering remenants are causing a conflict with another card which causes it to blue screen.

Ive tried searching for the individual driver files and deleting them but when i plug the old card in, in device manager it still knows what type of card it is and its name but it just comes up with the yellow ! as it cant install it properly, probably because i delted some of the river files.

So can someone tell me how i can completely remove all referance to the old device so its is completely clear of it?

You need to find the OemXX.inf file that relates to the card in C:\Windows\INF, delete that and the relevant PNF file and it will no longer be recognised. You may have to open a few with notepad to find the right one.

Edit: Then delete the device in device manager
