Having problems with your Dell Latitude C640 Notebook ?
Red vertical lines appear, can only run computer in Safe Mode
\015 Model: Dell Latitude C840\015\012\015\012When I turn on the computer, white underscore lines appear across a page that indicates to select to enter in Safe Mode. I didn't click anything, so it automatically goes to start in regular mode.\015\012\015\012Windows XP attempts to open (has green vertical bars that appear as it is trying to load). Then a blue page flashes briefly saying something like "sorry for the inconvenience..." and then the screen goes black.\015\012\015\012Then, after about 5 minutes, the computer does this all over again. \015\012\015\012When I select to run in Safe Mode, Windows XP loads, and I can access my files, but the screen has lines across it (it is also made worse when I press on certain parts of the laptop).\015\012\015\012Any ideas? I'm thinking it could be the video card. Any suggestions? Thanks\015
