I need to clear things up a bit for me, You have ONE monitor attached now, but the computer thinks there is a second "ghost" monitor and thinks that second monitor is the primary one with all the icons and background correct? So you can see the background but no icons? And you can't change any settings because all the screens and dialog boxes go to that ghost second monitor right?
If that's the case, try booting in Safe Mode, then go into the screen resolution option, see if there is only one monitor there. Click Detect, reboot, and see what happens.
I'm so glad someone understood what I meant! Yup, you hit the nail on the head. As for Safe Mode, I think I either tried it & it didn't work or I couldn't get in to Safe Mode. (I was standing on my head installing a video card into another PC today, and my brains are fried.) But I'll try again, thanks.
