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.

The OP's computer doesn't match the repair extension program. OP has 13" non-Retina 2012 model, repair extension is for 15" Retina 2012 model.

Some questions for the OP:

1) When do the glitches happen - all the time or some of the time. If some of the time, is there something that consistently triggers it?

2) What OS (including update level) are you running? When did the glitch start happening relative to any OS changes you have done?

3) What's the chronology and details of the service repairs and when the glitch started happening. So, when and what repairs have been done on the computer and when did the glitch start happening relative to these repairs?
 
I second the memory suggestion. Integrated graphics uses some of the system's RAM for its video memory. Since you're running aftermarket RAM, I would look to that as the first possible cause.
 
go as soon as possible for the extended repair program (which will be expired soon! as of mid february !) and take your pictures/videos with you!

Unfortunately, the extended repair program only applies to units with the dGPU, which would not include the 13" model referred to in this thread.
 
Knock on the keyboard around the WERT keys and see if it makes the display freeze up with distortion. If that doesn't do it pick up the machine and flex the top case. If either of those make it happen its the logic board.

Except the OP has a 13", which doesn't have a dedicated graphics card and thus does not qualify for any repair...

As I stated already on Thursday (look at the second quote) this is right and I was wrong.

But it doesn´t hurt me to repeat that a second or third time - if you want me too…. ;)
