macbook pro 13 inch mid 2012 replacement screen

When I visited the Apple store today, I was told that my model does not have a GPU chip but rather the graphics are run through the CPU. Before I came in today, I did a lot of web searching and found out that many people had GPU problems and some were able to get their logic boards replaced free of charge, but my model MBP doesn't fit the one Apple sent out a recall for. Earlier in the morning I tried to do a Apple Hardware Test at home and the screen freeze happened AGAIN. So today, July 1, 2015, I went to the Apple Store and Genius Bar once again. I have on several occasions taken a picture on my phone of the screen freeze and horizontal lines, however, I couldn't really find anyone else on Apple forums or on Google pictures that had the same type of problem as I do. Since then, I have been doing this method but I feared and still fear that this can only last so long before my MBP completely dies out. However, I discovered that an 'quick fix' to this problem was to simply remove the RAM and put it back in and then it would start up like normal again. So at this point, I am convinced that it cannot be a problem with the RAM. I was convinced my problems were solved until not too long later, I once again got screen freezes and kernel panics. I ordered my RAM off and put it in on my own. Once again, I was told that it was a problem with the RAM, only this time, the Genius recommended that I upgrade my RAM since my old one was deteriorated. This lasted until mid May when the computer would not start again and once again had the 3 beep intervals.I scheduled another appointment at the Genius Bar and went for myself this time. I think there were still some screen freezes here and there but when I force shut my computer off and restarted it, it worked. My friend told it it was 'fixed' and for a little while it operated okay.

The Genius at the Genius Bar told him that indeed it was a problem with the RAM and to my knowledge, all the Genius did was take the RAM out and put it back in.

I looked up a bunch of other forums online and found out that it was most likely a problem with the RAM so I had a friend take it to the Apple Store for me since I was busy with school. After that kernel panic, my computer would not start up and instead would beep 3 times in each interval with about 4 or 5 seconds in between each interval. This became more frequent later until one day I had my first kernel panic. So a couple of months ago, I started getting screen glitches and freezes while watching videos. I have a Mid 2012 Macbook Pro 13 Inch notebook.
