Please restore your computer to a point before DRIVERfighter by opening DRIVERfighter and click on "History and Restore" in the left menu. Click on the green button named Driver Restore.
Chose the latest date where your computer worked and continue the restore process.
After this you may need to reinstall your DRIVERfighter again if it is not there anymore. Run a new scan and update one driver at the time, if you have issues after installing a specific driver then you should restore again and place that driver on “Ignore”. You are welcome to contact us with the information about what driver you had issues updating.
