Sounds to me like you need a new battery.

It is a new battery, tested it with a volt meter and everything.

I've moved the motherboard from the case. Running it on an antistatic
mat with just the video card (7800GTX PCI-E) and a SATA hard drive it
only gives the 0251 error about one time in ten. However if I hook up a
SATA DVD-R/W it goes back to erroring out every time the system is
powered on.

I'm stumped. I can live without the SATA DVD-R/W, but I once I setup my
SCSI RAID I cant be needing to reset my CMOS configuration even once in
ten boots.

Tyan has not yet responded with anything other then a canned auto
response. Going on week three now. Is Tyan no longer a good company?
