Thanks for that info. I thought that it would be fairly accurate, being part of the Windows set up and didn't give any thought to the cmos battery. I switch off every night but do not pull the plug, and am probably paying for it in my electricity bill. Mobo is 9 years old and I'm surprised everything is still working. I think until I get further warnings I'll operate " if it's not broken don't mend it", but with your warning I'll watch carefully. I will be buying a new PC in a few months time. Thanks again, have a great new year.
Mobo nine years old. You've done very well lol. If your'e buying a new machine in a few months then I wouldn't worry just re-set the time. I know you'll get a cracking, up to date PC and will be interested what you'll get and how it goes. Happy New Year to you and yours.
