So I have been having a lot of problems with my 15" unibody core i7 MBP where it just hangs for a long time (5-10 minutes) or indefinitely. I thought it was a software issue so I did a fresh install from the system disks and I am still having problems. One problem that reoccurs randomly is the login screen appears when the laptop boots up but doesn't completely fade in, not allowing me to type in my password. http://alan-torres.com/post/images/login_freeze.png Out of frustration I started mashing random keys and voila! it finished fading in. The other night Aperture didn't want to open when I was trying to show someone some photos (this happens randomly as well). I explained my laptop problems to the person and jokingly smacked the bottom right corner of the laptop a couple times. The screen distorted for a second but then all of a sudden everything unfroze and Aperture loaded up. Next time I need to get it on video, it was quite humorous. Another strange thing is that now Photoshop will tell me that there is a problem with the display driver whenever I open it. http://alan-torres.com/post/images/driver_issue.png This has to be a hardware issue right? I am thinking that the violent mashing of keys and smacking is moving something inside of the laptop to make it work. It's just kind of frustrating because I know that if I go to the apple store that my laptop will magically be issue free. What do you friendly forum-readers think?
