Hi flyingseth!


Welcome to the Community Forums. 


If your laptop is not booting with the 16 GB RAM, it's possible that the RAM is defective. Check with the store for return option.

Are you allowing several minutes @ the black screen.  Memory updates - big ones - can cause this while BIOS does whatever it does to assimilate new memory.  Once past that it's fine - if that is what is going on.
