BOAC, I would go to your mobo website - they may have something for you.
Meanwhile if it doesn't stop, I would recommend flashing the BIOS to the newest revision (W a R n I n G - potentially harmful - may kill the mobo especially w/o an UPS) or better yet, give the techies at the mobo company a crack at it - and req a new one should there be no resolution.
This is not normal - and may eventually leave you with no pc. The BSOD may be related to the CMOS problem or even a bad ram chip.
