  • Press Win + Ctrl + Shift + B to reset the graphics drivers.

8. System Restore

• If Safe Mode works, perform a system restore to revert to a previous state where the laptop was functioning properly.

9. Update/Reinstall Drivers

• Update the graphics and other critical drivers from the manufacturer’s website.

10. Hardware Issues

• RAM: Reseat or replace the RAM modules.
• Hard Drive/SSD: Check for loose connections or consider replacing the drive if it’s faulty.
