Install driver on safe mode


###Method 3: Roll Back Drivers
If your driver is corrupted due to a new update, roll back will set your driver on the backdate when it was working fine. 
To roll back your driver open **Device Manager> Display adapter> Properties> Driver** tab.

![SYSTEM_THREAD_EXCEPTION_NOT_HANDLED ](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/dbvqp1id941gxrteeo7l.png)
 
Select roll back to the previous date.

**Note: If the roll back option is greyed out, it means there is no previous driver recovery, and you cannot Roll Back your Driver.**
###Method 4: Repair corrupted files by using Deployment Image Servicing and Management (DISM) commands
Run power shell as an administrator and execute the following commands. These commands will take more time so be patient and run the next command when the previous is completed successfully.
This command scans the system and replaces corrupted files if they are present.

```
sfc /scannow 
```
 
 This command checks out whether the system can repair the damaged files or not.

```
DISM /Online /Cleanup-Image /CheckHealth
```

It scans the system for any damage.

```
DISM /Online /Cleanup-Image /ScanHealth
```

It repairs the Operating System that is running currently.

```
DISM /Online /Cleanup-Image /RestoreHealth  
```
