CMOS Settings Wrong

Everythings been running fine for ages then suddenly over the last two days I get the following message on boot up:

CMOS settings wrong
CMOS Date/Time not set
Press F1 to run set up
Press F2 to load default values and continue

When I go into my BIOS I find it has forgotton the time and my boot order. Any ideas what is causing this?? PC is as per sig.

I'm about to back up all my photos/documents and run my AVG antivirus programme just in case!

Yep. It runs fine until the next time I turn it on!

Ok I'll try a new CMOS battery. I've read my ASUS Mobo manual and there is no information on replacing the battery! Is it a straightforward job? Will I lose all my BIOS settings? The battery is a lithium CR2032 3V. Can I get these from a camera shop or do I need to go to a PC store?

Thanx. No problem to fit then?
