Hello, I have a MacBook Pro 15,4" mid 2009 2,66GHZ, 256GB SS Crucial m4, 4GB RAM. If I start the MacBook Pro, its starts normal bur after I work with it and it is warm and I do a reboot, sometimes it starts with black, white and coloured stripes. It can also happens after the hibernation. If reatsart the MacBook Pro more times it works fine. Look at the attachment. Can it be the graphic chip? Thanks for help.
