hello, i am running adobe cs5 on my early '12 macbook pro, 8 gigs of ram and plenty of hd space. recently my computer has been crashing white using programs in adobe, photoshop in particular. when the crash occurs, a screen with a grey and black vertical bar appears and i am forced to manually reboot the computer. often times upon reboot the screen appears to be pixelated in a strange horizontal pattern and at times has failed to reboot completely. this obviously worries me as my computer is brand new. the hard drive is partitioned with windows 7 installed, if that is of any relevance. any advice would be most appreciated.
