So, all of the sudden, I now have an aqua blue screen instead of white. I didn't change any settings, that I am aware of. I have a laptop, it's about a year and a half old. I have had issues with it overheating and shutting itself off for the past couple of months. (If this is helpful in any way.) Any clue as to why now everything is blue instead of white? it's everything, web pages, word documents, etc. Even when I'm on facebook and someone has white in their picture, it comes up as blue. Any clue what the issue is, and how I can fix it?
