What kind of problems do you have on the Phenom?

I have a Phenom running 64bit 8.10, and I have some problems as well.

The USB ports are intermittent (a reboot always fixes them), the sound
quit and none of the fixes I found with Google work (it works fine
from a live CD), Firefox refuses to download files, and Folding at
Home randomly stops working (I've tried it w/o FAH, in case FAH was
causing some of the other problems, as some people have had trouble
with it, but no improvement).
