I have an Acer laptop with Windows 7. I have no idea what I might have done. I really don't do much on my laptop except go on Facebook and Gmail.

I have never tried to change the color of my web pages and home page. Everything just changed colors on me and I have absolutely no clue as to how or why. Everything used to be white, same as when I first turned on my laptop 3 years ago. Now all my backgrounds are aqua or a pale lavender, with pink borders. It is affecting other things on my laptop, like viewing photos. They have red streaks through them, and are difficult to make out. I have tried everything, but nowhere can I find where these colors can be changed. I have found where to change colors, but nothing works. I figured somewhere it would show current colors being used so you could change, but no luck.

I am very technically challenged, so a lot of these help sites have been no help for me. I would really appreciate it if anyone can tell me what happened and possibly give me a fairly simple way to rectify it.
