As in the title, I have quite an old MacBook Pro. I bought it in 2013, and recently on some apps or webpages, at random times, my screen is glitching on the top side. I tried checking to see whether it's a screen issue or not, but when I tried to connect it to an external display, the glitch still appeared.
So I made an assumption its a graphics issue meaning a logic board issue.
My questions are:
- What will happen when I change to a new logic board? I mean I am a custom PC user before, but I never tried to change a motherboard / logicboard on a laptop before. Will it have an issue with the software?
- Can I replace my logic board with higher version of my current logic board?
- My processor right now: 2.5 GHz Intel Core i5
- I want to get: 3.1GHz dual-core Intel Core i7 processor (I'm not sure this type is compatible with mine since it's the latest core for "old" MacBook Pro in the site, but I hope you get what I mean)
