Macbook Pro Hangs/ Shuts down
Hi,
My MacBook Pro suddenly stops working. There is a horizontal line that moves across the screen vertically and then a message is displayed
" You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again."
This has happend multiple times.
Any suggestions on the issue and solution?
MacBook Pro, Mac OS X (10.7.3)
