Likely mysql_upgrade

IMHO, much easier.  I, also, am far from being a MySQL admin--and plan 
to keep it that way.

Playback profile problems?  Or video driver installation problems.  
Almost definitely unrelated to database.  (Though, if your hostname 
changed, it may just be that you're not using the settings you 
previously configured for that host and stored in the database, so 
you're getting all defaults--including the 
poor-choice-of-playback-profile-group, CPU+.)
