I do like to disconnect from internet ( disable the network card or wireless till you get it done ) when I use his guide to remove the Nvidia drivers. If you are connected to the internet Windows 8 ( my OS, dunno about Windows 7 ) keep installing Nvidia drivers after you removed it.
Driver sweeper has been known to remove important chipset files which will result in errors such as instability. Some users have reported that the sweeper software removes “False positives” and may cause the user issues when trying to install software such as drivers. The error usually reports that an .ini file is damaged. Over long term use of driver sweeper, it could cause several underlying issues which will do more harm than good.
This guide is an alternative, which removes all the files and registry entries that need to be removed for a successful uninstall. This is useful for upgrading/downgrading drivers or switching to another brand of card.
1. Go to Add/Remove Programs
2. Uninstall all Nvidia associated software (May require several reboots)
3. Reboot the computer and log back into windows as normal
4. Go to folder options and select “show hidden files and folders”
The next part of the guide will remove all Nvidia files and folders from the computer.
5. Go to your C drive and remove any “Nvidia” folders if there is any
6. Double click the “Program Data” folder (Normally hidden) and remove all Nvidia folders

(Remember, if you look in some of the folders mentioned in this guide but don’t have any Nvidia folders, just move to the next appropriate step. This means the uninstall option has removed such files for you. But as we know, the uninstaller still leaves a lot of things behind)
