I'm ready to to on record with this. The Serious Errors I get are caused by either corrupt preferences or corrupt media cache files.
It happens several times a day. Way too often.
Pr also can corrupt the nVidia driver.
The evidence: I will get repeated Serious Errors, and either deleting/replacing the prefs or deleting the Media Cache files and letting them rebuild will let me resume working... for a while.
I've even had to reinstall the my Quadro 4000 driver in order to get back to work.
