I have a GeForce 550TI with 2 monitors on it.
Some weeks ago, I unplugged one monitor, while windows was running, and I restarted the computer.
Since then, when the computer restarts, I can't see anything, such as the "POST", until the Windows 7 login screen show up.
Actually, at first, I did not see anything at all, I had to remote desktop from another computer to have something show up on my computer screen.
When I go to the screen resolution screen in Windows, I have a "ghost" VGA display plugged as monitor #2 even if nothing is plugged in the VGA port.
(I tried using VGA, DVI and HDMI separately but it does the same thing.)
Anyone have a clue? Is there an on board memory similar to CMOS that can be clear on the video card?
Thank you for your help
