cmos checksum error

Hi,
I was advised to reinstall my Vista Home Premium from an OEM disc after
various startup problems. (Unfortunately the 2007 PC's OEM is Evesham UK, who
since going bust and changing ownership no longer seem to offer proper
support on pre-takeover models...)
On about the third try the disc seemed to reformat my hard drive, install
OK, and download/install numerous updates with few hitches. I reinstalled my
Bullguard 8 security suite OK, and a day or more later WinUpdate offered SP1
- which I haven't done yet because meanwhile two attempts to reinstall Office
from disc failed, giving a blue screen which went too fast to read it, and
getting me into safe mode.
After a shutdown, the Foxconn startup screen reported a "CMOS checksum error
- defaults loaded - 05/24/2007 - Broadwater - 6A79LFKFC-00". It would not
proceed without choosing a normal start or checking out the BIOS. I looked at
the basic CMOS settings, and found the date had reverted to 01/01/2006 - so I
corrected that, and then did a normal start.
There's clearly something wrong, but my amateurish attempts to diagnose it
by web searching have delivered nothing sufficiently informative. Can some
expert make sense of my issue and suggest solutions?
Thanks.

This could be a bad battery on the motherboard causing the loss of settings
or it could be a faulty motherboard. If you are not skilled at hardware
troubleshooting, enlist the aid of someone who is. Replacing the battery
would be my first try.

On top of what Richard advised, did a CD come with your computer that
contained the Drivers for your Motherboard?
