Also, is the equipment:

	1. Verified to be getting a *good* ground? (Most commercial and
	residential convenience-outlets provide poor grounds, and sometimes
	aren't even connected. In one building [brand new, by the way] we
	had to install a seperate ground-cable for the computer equipment
	because the code-approved grounding was obtained by attachment to 
	the conduit: ok for running typewriters, etc., but won't hack it for
	electronics eqt. Have it checked by someone competent.)

	2. Getting power that is "conditioned" to kill transient spikes and
	other variences? Better, is the equipment on an uninterruptable
	power supply? When power returns after failure, the spikes can be
	really awesome in the first few cycles.

The long-term effects of poor power *can* generate exactly the kinds of
symptoms you have described, and standard commercial power is rarely very
stable.

Hope this helps.
