A failing RTC CMOS > battery? We have had a few of these at work and these symptoms were cured by a new CMOS battery. The voltage on the battery has likely dipped to 2.9-3.0 volts; they get unreliable then (i.e. it's dead.) If you leave it long enough you'll start getting RTC errors on POST. I'd try that first, assuming you can still get the CMOS battery for these. Dan
