3 Beeps after High Sierra update

MacBook Pro - MacRumors Forums - forums.macrumors.com
Hi guys, I have a late 2011 17inch MBP, everything was fine until I updated to High Sierra, now I am getting three beeps on startup and it isnt loading the OS. Seems the 3 beeps is usually associated with ram, but why immediately after the update? It will boot into safe mode and recognizes all of the Ram installed.
