After installing a device driver, the device or the whole computer doesn’t function properly.
1. Driver rollback.
This cancels the last device driver installation. Use this if you run into small annoyances, or problems, that are related to a specific device functionality that doesn’t prevent computer from working.
For example: after installing a new webcam driver, the picture became blurred or unrecognizable. Or, after installing a graphic card driver you are unable to change screen resolution or frequency.
You can roll back driver for a specific device by opening Device Manager:
Locating Device manager in management console:
Selecting a device, which you suspect to have problems with:
And clicking “Roll back driver” in drivers tab:
2. Last known good configuration/safe mode .
If you are not able to start Windows normally after installing a device driver, you may need to start your computer in Safe Mode to follow instructions described in part 1. Or, you can use Last Known Good Configuration to boot up.
In order to access these functions, you have to push F8 key several times to get a boot menu. It will look like this:
3. System Restore.
While not being the best solution for solving driver problems, it may help if you installed some software package that came with drivers. Usually, printer/scanner manufacturers, as well as graphic card vendors provide additional software together with drivers. If you believe that these managers are causing the problem, system restore is the way to go.
