Is flashing question mark folder death of SSD or logic board?
I am getting flashing question mark which means no OS found. But sometimes my system boots normally and works perfectly fine until I shut down and reboot only to find same error.
I ran diagnostic test and found error VDH002 which says an error with storage device.
I installed macOS on an external drive and booting from it seems perfectly fine. Before buying a new SSD for my Mac I thought to confirm if it is really the culprit or is the logic board. When I removed the top cover of my Mac I found some weird marks on the logic board and SSD (see pics). Is it normal or is it some moisture?
