A1370 screen glitches/pixelates and freezes.

[RickW86]

Good day everyone.
I have a macbook air A1370 which has started to present a weird issue. It turns on and works fine until randomly the screen becomes glitched/pixelated and the macbook freezes. I've attached a video of the issue so you can see what I am talking about.
(sorry for it not being focused properly, sometimes my lg g5 also glitches and won't focus properly, but that's a whole other issue.)

Has anyone seen this issue before and knows what causes this problem? and maybe knows a possible solution?

That's either the GPU or logic board that is dying.

Any chance its related to the ram? This unit did have the 3 beep error before and had its logic board heated in a oven to fix that error. I did run the extended diagnostics test booting up while holding "d" which didn't find anything wrong.

I can't say. I don't recall the beep codes.
