I returned from vacation and my computer screen was black with white letters: 1:Analog output. Cannot display this video mode. I can see a screen in Safe Mode. I have tried to update the device driver, to uninstall, reinstall, download new, to use original driver from Dell Resource Disk. Everything I can think of. Three times I have run an operating system "repair" (using a Windows Home Edition with service pack 2 from Dell) I can get to the desktop but the display isn't right, so something continues to be wrong with the driver. If I try to change the driver at that point, I end up back where I started. This has happened too many times already. I am obviously trying to avoid reinstaling the operating system because I have tons of programs and files on the computer. Thanks, in advance, for your suggestions. I'm at the end of my tether and, of course, working on deadlines.
