OK, here is what happened: 1. I was reading the news at Yahoo. 2. I went to take a shower. 3. About 30 minutes later, I returned to my computer and found that the colors of the screen had been strangely altered. For example, the bars at the very top and very bottom of my screen are normally blue, just as they are on virtually everyone's computer. Right now, though, those bars on my computer are green, blue, purple, yellow, red, and so on. The text and objects within every window I open, the icons on my desktop, my background -- everything that appears on my screen -- are likewise altered. Since this occurred, I haven't encountered any problems with the operation of my computer. Does anyone know what might have caused this? Could this be due to an automatic Windows update (my computer indicated an update)? I'd like to change my screen back to its original appearance as all of these colors make it more difficult for me to read what's on my screen and prevent me from knowing the true colors of any pictures that I look at.
