I receive display error while switching on the computer (HP Pavilion dv6670ec).
The screen splits into 6 parts (6 same small displays within my screen)
The error appears just while starting the computer.
I tried to reinstall graphic card drivers (NVidia 8400 GS), but received the error message, that it's not possible to install (current max resolution is just 800x600)
I also tried external display (through VGA) - no response
I tried system repair - no result
BIOS doesn't show any graphic card information. After system repair, I'm not able to see anything when logged in Windows (I see just initial process on the screen)
Any suggestions what could be the issue?
