i have a dell dimension xps m233s w/windows 98 and a couple of days ago i unpugged it and moved it to another room, when i plugged it back in and started it up the light on the monitor would turn green and after a couple seconds it would turn to yellow but nothing would come up on the screen. i tried another monitor but the same thing happens, and i also reseated the video card and still nothing. i'm very concerned because i have important data on the computer that i need soon and i refuse to wait on hold with dell tech support EVER again!!! Please Help!!!
