It's a HP Pavillion s5510p Slimline-only 2 years old. Was working on a spreadsheet when the colors disappeared. I see whites, blacks, light purple, pale greens.
Try another monitor as that is the probable cause of the problem.
I hooked up my monitor to a laptop and it worked fine. It must be the computer. What else could it be?
