Hi,

Can you try these steps?

1. Open the registry (run regedit.exe) and delete the this key:
HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDriv ers\Configuration
2. Delete the this key
HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDriv ers\Connectivity
3. Exit regedit tool and reboot.

Let me know how you get on.

Thanks,
James
