Hi, So recently i had the screensaver up on my mbp and the next thing i know, the screensaver was frozen with dozens of verticle green lines going across the screen. I restarted it and everything ran fine for a few days. Then, this morning, i go to open it up and those same green lines appeared. I tried to restart it again, but now when i restart it, those green lines appear at startup and a notice pops up saying i need to restart the computer. Obviously, that hasnt worked. Anyone have any ideas? Thank you!
