I am sorry for your trouble but let me help you.
The information you have provided is very helpful for me but I would like to check some more settings.
Can you please provide the following?
- BIOS version running on the computer?
- What other troubleshooting steps have you tried?
- Can you attach here your dxdiag report?
How to get it?
Dxdiag Report: Type dxdiag in Start Menu> open> Save> Attach Here using the Advanced Editor Option.
- Was this working fine before or it never worked?
