Picture Included. Mid 2012 13 inch Macbook Pro green/purple lines on screen. Freezes. Sometimes 3 beeps.
Alright I have a Mid 2012 13 inch Macbook Pro purchased in June 2012. For about the last month, I have this issue where as I am using it random colored lines will show up on the screen (lines usually green, purple, but occasionally the issue occurs while booting and lines are black on white background). As soon as the lines appear, everything freezes. Sometimes the computer automatically reboots. Other times, it will just turn off and start beeping 3 times in a row. AT first, I thought this may be a video card error because it happened a lot when I was watching videos. However, it also happens randomly when I am just using safari/chrome with no other programs runnings. The most annoying part of this issue is that it is completely random. Computer won't act up for maybe 2 days straight during all activities (videos, surfing the web, etc). Then I will have a day where the problem is consistent.
Also, although I think this is just a correlation, all problems started after upgrading to Yosemite.
Picture below:
Does anyone else with a Macbook Pro (especially 2012) have this issue? These two discussions seem to be describing this very situation:
MacBook Pro, OS X Yosemite (10.10.2)
