iMac freezes + WiFi card issue
Hi all and thanks for stopping by.
My old buddy iMac is having some issues:
1) it freezes. most of the time when you try to run a game or Geekbench GPU test. it's just 100% that it will freeze within 20-90 seconds after you start a game / Geekbench test. Rarely it can freeze during ordinary web surfing or even while loading the MacOS (the Apple logo and progress bar at ±50%).
No glitches or other GPU artefacts. Just a frozen image and cursor is not moving (sometimes you still can move it, but nothing works).
2) it shows "WiFi hardware is not installed", though i have my bluetooth working. Heard that there was an issue with late 2013 A1419 model when malfunctioning WiFI card can lead to freezes so i tried to replace the WiFI card but had the same problem - "no wifi hardware installed" + freezes.
I even tried to run the iMac without WiFi card, but freezes are still there.
I also did MacOS reinstallation, SSD check (all good), Geekbench CPU tests (all good).
I'm thinking of GPU issues since i can force these freezes by just running a game / Geekbench GPU test, but the problem with WiFi card ruins all the theory of malfunctioning GPU.
any ideas?
Spec:
iMac late 2013
CPU: Core i5 3,4GHz
Ram: 8GB DDR3
1TB SSD
GTX 780M 4gb
MacOS Mojave 10.14.6

checked the console and everytime i get freezes, the "com.apple.DumpGPURestart" appears, so i guess the GPU / vRAM / GPU power supply is dead.
