Start up began last week with a gray slow screen - past two days 13" mac is slow loading and loading in sections of white blocks on my screen - is it JAVA? What to do? It happens if I walk away for a short time, if it goes into screen saver and or if I put lid down -  Got 13 " alumn case with Mtn Lion September 2012.
