I have a Dell Latitude (laptop) C640 with the standard Radeon 7500 video and am running XP Pro SP2. I recently was updating the video driver and after running into some problems while doing so, I managed to remove the Display Adapter (why oh why does Plug and Play not recognize this??) After rebooting, I only get a blank screen after the welcome screen. The computer seems to be operational (wireless pci card is on, hard drive reacts from pressing the keyboard, CD drive reacts to a cd being inserted), but I cannot do anything. I have tried ALL of the modes under the F8 screen, but only get a blank screen with blinking cursor or just a blank screen. I cannot boot from my XP install disc, because nothing shows up on the screen. I have tried to connect to another machine via network cable, but need a password (which I never set up) to log on. I am at a complete loss. Any helpful suggestions are greatly appreciated!!
