So, while surfing the internet (I was reading an article on CNN and scrolling down to continue reading), the screen color changed to tinges of green and purple. The entire thing froze...no keys, no mouse, not even force quit...nothing. I had no choice but to do a hard shut down by holding down the power button until the laptop just shut off (Macbook Pro). In the middle of rebooting, (at the grey screen with the apple logo on it, I got the familiar circular dial that ticks around as it loads) a screen wipe similar to the effect of some screen savers went from the top of the screen to the bottom turning the screen from grey into green and purple vertical stripes. It also said "you need to restart your computer" and proceeded to tell me how to do so in four different languages. Upon doing so, the same thing happened...several times. I tried booting it into safe mode by holding down the shift key until the grey apple background appeared and it seemed to be working as the loading was taking forever. Alas, the same thing happened. I took the battery out and held down the power button for 10 seconds, put the battery back in only to suffer the same effect. The next genius bar reservation isn't until Friday. Any ideas or advice?
