- Right-click on Start and select Device Manager.
- Expand the categories to find the device you want to update.
- Right-click the device and select Update Driver.
Roll Back Drivers
If youโve recently updated a driver and started experiencing the BSOD, rolling back may solve the issue:
- In Device Manager, right-click the device and choose Properties.
- Navigate to the Driver tab and select Roll Back Driver.
4. Run a System File Checker (SFC) Scan ๐๏ธ
Corrupted system files can be repaired using the System File Checker tool:
-
Open the Command Prompt as an administrator.
