System hangs on boot, if it boots it hangs soon. What to check?
Has been running reliably since @dan helped me last year with thermal paste issues. Suddenly the system will hang partially through a status bar or if it goes to user menu, it will let you log in but it will either hang within a few minutes or begin a restart cycle.
Tried to go into safe mode and it hangs there also. Tried recovery mode, started disk utility to check ssd and on pass 3 of 7, it froze!
A few times, a crackling quick pop was heard briefly…what should I focus on power supply? logic board? Thanks!
