Actually with weak motherboard batteries, I've seen a power spike/brownout do what you are describing.
3-4 year old battery, I'd think about replacement.

Since upgrading to RMS 1.3 we have encountered some really strange errors.
<BR>> The last one is the best. Right in the middle of the day,
yesterday, ONE of <BR>> our computers changed its own date from
12/30/06 to 12/15/06. Both dates <BR>> showed up in the
journal and the incorrect dates printed on several receipts.<BR>>
<BR>> Today, one of our computers changed its own date to
12/31/2007. I KNOW no <BR>> one changed it. <BR>>
<BR>> Please, no jokes about the Y2K06 bug. Unless they're
really funny.<BR>> <BR>> Anyone else seeing anything like
this happen since the 1.3 upgrade?<BR>> <BR>> All our
machines are running XP Pro with automatic update turned on. We run
<BR>> hardware and software firewalls, use AVG anti-virus
protection, and Windows <BR>> Defender (latest
version).<BR>> <BR>> Just crious.<BR>>
