Last night I installed a new SSD and 8 GB of RAM into my Late 2011 MBP. Everything was going smoothly until I installed the OS onto the drive. I now have a complete mess of a UI and it's darn near impossible to do anything on the computer. However, when booting into Safe Mode, the problem is nonexistent. The problem also did not present itself when I put the old drive back in and booted from it. It seems to either be user error and I totally screwed up on something when either making a USB Installer, lack of comparability with drivers, or a faulty SSD. To be honest, I'm more leaning toward software problems with Safe Mode working. Everything functioned while running OS X, but it was VERY difficult to do anything trying to see through the snowy random pixels and constantly warping windows. I have attached some photos to show what's going on. Any help would be GREATLY appreciated. PS. The logic board is brand new and I could do anything graphical I wanted with the old drive. Odds of it being a video card failure are slim to none. Also, I've tried installing Mavericks and Mountain Lion to no avail. PSS. For some weird reason, whenever I open the install usb from my desktop, the window is free of distortion and can be used to "scrub away" any distortion it touches. It's just weird... Picture 1 is Safe Boot Picture 2 is as the system boots up. There is no screen distortion. Picture 3 is the problem at Login.
