what do you mean by shut off 'power management'? do you mean disable all (hdd, monitor, system standby) from going into effect after a while? if so, yes, i have my power mgmt set to never put anything on standby. everything is always on.
as far as AV is concerned, i did a recent clean reinstall and haven't put AV yet so that is not the problem either.
thanks for the tip though. anyone else have any ideas???
