Macbook Pro 13" 2015 Glitching & Freezing

[vince_glitch]

Hi!

Recently my Macbook Pro started freezing and the screen would pop fuzzy red lines over what I am doing, a
few seconds later, it would shut down. At times it would even totally glitch out, scrambling my screen.

I did a diagnostics test and it showed an error code PPN001, saying I have issues with my power management system.

I also did some Googling, indicating this might be a GPU failure, but my model doesn't have a dedicated GPU.

I have no idea whats going on, can anybody shed some light?

I had similar stuff happen on my 2015 13, except diagnostics would show nothing. It _only_ happened when watching Twitch tv streams and when the browser had adblock (I think), especially in Safari. That was at the end of 2017. Never happened anywhere else, even when playing heavy-ish 3D games.
