you said when it shows just one processor the system performance does go down
to a large extent. therefore you might want to check for bios updates at your
board manufacturer's website or better still just give them a call and ask
them as to what's going on. though it may not help much but well worth a try.
anyways is your system still under warranty??

hope this helps
