Yesterday, I found some problem with my MacBook Air. I was doing some office work on that and then suddenly the whole screen becomes black and I was not able to see anything on that. The only visible thing on the screen was the mouse pointer and was movable. After that I closed the computer and pressed few keys and I found that the pointer turn out to be the revolving multicolor circle and from then it stayed in that state only. Please guys help me to solve this. If you have any idea or any suggestion for this then please post it over here. This will be very helpful for me. Thank you very much in advance.
