Why are there horizontal lines randomly showing up on my screen?

I bought my MBP back in 2012 and I haven't had any problems since. However, this past week has been really trouble some as it didn't want to turn on at all at the beginning of the week (this was fixed by unplugging and plugging back the battery connector).

This is a GPU issue. Apple are now repairing all MBPs that have this problem. Book an appointment in the Genius Bar. I had the same issue with a MBP2011 and they fully replaced the entire thing for free!
