Hello. I have an IMac late 2009 on which I installed windows 7 using boot camp. I installed Garry’s mod on windows, then launched it. I stay in the menu for a few seconds, however another app forces me to return to desktop (Garry’s mod still running on the background) and the screen starts glitching (black and purple dots appeared instead of some windows) so I restarted the computer. I receive a BSOD (STOP: 0x00000116). I restarted again and the same thing happened. I restarted it into macOS and it started glitching the same way. I restarted again and now Mac freezes on the loading screen. They both are able to start into safe mode without any problems. What should I do?
