Windows 7: Nvidia Driver currupted, cannot uninstall or install over

Hi people.
As the title suggests I have some driver problems..
Today I tried to install over my Nvidia Drivers because Minecraft was running into problems.

I went to start the installer it went to check my system for compatibility it did that for about a millisecond then went past the options screen and gave me "Nvidia Driver Installer Failed" with no explanation. I just assumed that the drivers had to be uninstalled before re-installing.

I uninstalled the drivers in safe mode through (control panel > add or remove programs)
and hence why I am asking this question the same screen came up "Nvidia Driver Installer Failed" without going to the option screen.

When I check the device status Windows gives me "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)"
Clicking un-install on device manager does nothing.
I've tried using driver sweeper and multiple techniques has anyone got any suggestions?



I also tried system restore but I accidentally cleared my restores the other day (silly me) and windows update gives me an install error 800f001D8 or something along those lines, I googled all of these and found nothing useful.
System Specs:
Win 7 64-bit
2 GTX 570's in SLI (re-seated them twice to see if that would solve the problem but, no.)
Gigabyte GA-X79-UD3
Intel i7 3890
12GB of RAM

Try device manager, right click your gfx driver, properties, try roll back driver. Once its fixed it then install the new driver on top choosing custom install and tick clean install.

Let us now how you go on.

The "Roll back" button is greyed out
