I've had my MBP retina 13 inch since mid 2014 and it was perfectly fine up until this Febuary. It started to crash while playing mildly intensive games and would extremely distort the video. It had red and black horizontal lines and if a sound was playing through the speakers when it crashed it would make really off sounds. Me and one of my other tech savvy friends believed it to be overheating, and for the most part that is still true. He told me to download smcFancontrok and that helped a bit. Computer would crash when it got around 125-130 F. Recently it's been getting more and more frequent, and crashing around 110 F. I use it for school and it crashes in the middle of class at least twice a day. I searched up the symptoms online and it seems to only happen to 15in and 17 in models, not 13 inch ones. It's also not covered by Apple. Could anyone help diagnose what the exact problem is with mine as well as give me an estimate of how much it will be to fix? I can't get it fixed till after next Friday because I have finals all next week.
