Hi Adec

Welcome to the Forum.


If you had looked at the many posts in the Driver Booster section relating to this issue, you would have obtained the solution.

You must start your pc in Safe mode, launch DB and rollback the driver which caused the issue to the previous driver which worked.


If you diid multiple driver updates and are unsure which driver caused the issue, rollback one driver at a time until you find the offending driver. Note the driver and post the info here so that Iobit can investigate the reason.
