My Macbook started having problems lately with horizontal glitches flashing on both its display and an external monitor when I have one connected. I took a quicktime screen capture video when it was happening once and replayed it once it went away only to see that there was nothing there, so I believe it's a hardware problem and likely the HD4000. I have an 850 EVO 500gb ssd and 16GB of RAM from crucial in it. I've never had a problem. I've done all the resets and the problem persists. I have Applecare that expires this February 7th. Every time that I've had an issue I've just put in the original hard drive and memory and they've serviced my computer. What do you all think my issue is and do you think that if I show them a video I took with my phone (screenshot of that paused is attached below) they will replace my logic board? I need my computer for midterms and engineering projects coming up.
