How do you fix the blue screen problem on a PC?

To fix the blue screen error on a PC, boot in safe mode, note any driver failures and attempt to reinstall. If there are none, check for hardware conflicts in Device Manager to reinstall and if there are still none, perform a system scan in safe mode for spyware, adware and viruses. If none of these options resolve the blue screen error, try to boot the PC in the "Last Known Good Configuration," then with "Enable Boot Logging" to identify the problem application to uninstall, or else perform a system restore.

To fix the blue screen error on a PC, follow these steps.

1. Boot in Safe Mode to determine driver errors

Boot up the PC and press F8 before the Windows screen. Select Safe Mode and as the PC boots up, take note of the last .sys file that appears before the boot up fails. On another computer, search for the .sys file and attempt to reinstall the associated driver. If the PC boots up in Safe Mode without problems, go into Control Panel, then System and click on Device Manager. Check each device for driver errors and attempt to reinstall the relevant driver.

2. Scan the system

If there are no driver errors, run spyware, adware and virus scans in Safe Mode, using software, such as Malwarebytes. Also scan for Registry problems with an app like Little Registry Cleaner.

3. Boot Last Known Good Configuration

If the blue screen error persists, reboot and press F8 before the Windows screen. Select the Last Known Good Configuration option.

4. Restore system

If the blue screen error persists, perform a system restore by going to Control Panel, System and Security, then Backup and Restore. Select "Recover System Settings for your Computer" and choose a date before the blue screen error first occurred. Click through the system restore wizard.

5. Buy a new hard disk

If the blue screen error still persist, replace the hard disk.
