Drivers that have not been removed from the system after uninstalling the device and software can have a serious impact on system stability. You could for instance be in a world of trouble if you have been using a Ati card and Ati drivers and switched to a Nvidia card and drivers. Driver leftovers could affect system performance and be the reason for crashes and bluescreens.
Driver Sweeper can be used to get rid of leftovers after the normal software uninstallation has been executed on the system. It is basically a software that makes sure that no old or incompatible drivers are still installed on the system. It currently supports Nvidia and Ati drivers, Creative (sound), Realtek (sound), Microsoft (mouse) and Ageia drivers.
The process looks like the following. The normal uninstallation routine is started, the computer is rebooted into safe mode and Driver Sweeper is scanning the system for leftovers and getting rid of them in the process. A log file lists all deleted files afterwards.
It is necessary to select the drivers that you want to scan the system for. This is however a pretty straightforward move and should not lead to complications. Just make sure you do not scan and remove the wrong ones.
