If you think that’s bad, try repairing an iMac. They glue the SCREEN to the computer itself, to discourage you from opening it.

Hello! I used this guide to change thermal paste on the GPU and CPU. First time I ever did something relative to IT/repair in my life (I am 30 years old). The guide was very well constructed.

It didn’t fix my problem (shutting down when trying to boot up), so I will try to roast the GPU card in the oven for 200 Celsius for 9 minutes. But that’s not this guides’ fault. Last hope, wish me luck!
