I don't ever recall having this problem on my computer before. There is a black screen with a square box moving around the screen like a screensaver saying the following: Dell 2: Digital Input Self Test Feature Check (grey background) Red (red background) Green (green back) Blue (blue back) White (white back) I tried shutting off power and restarting but the same screen comes up. There is no mouse on the screen either. I have a Dell, I believe its a Radeon, several years old but its always been reliable. I've been having to expand the virtual memory many times recently. Does anyone have a solution? Thanks! I also still have connection to my internet modem by my laptop. I have Windows XP.

Try hooking it up to another monitor. I got the same thing on an old Dell monitor that somebody was throwing away, and I just used another monitor in the meantime (it cleared itself up after a few weeks, and I never figured out why).

That sounds like a problem with the monitor.

Well you guys were right, yet again. My cleaning lady must have pushed a button when cleaning the monitor. I clicked some little button and the screen said Analog Input and went back to normal. Thanks a lot guys for the inspiration! Problem solved.
