Security certificate

[delmac85]

For some reason when I try to go on websites, yahoo, Argos, uswitch and others it keeps coming up that there security certificate has expired or not valid, any ideas why this is happening?

Right-click on the clock on your toolbar and select 'Adjust Date/Time'. You'll almost certainly find out that your computer has the wrong date set. If so, simply correct it.

If the problem keeps occurring it will mean that your computer's CMOS battery (also called a BIOS battery), which provides power to the clock when your computer is turned off, needs replacing. Instructions here:

Thanks buenchico, spot on! We had a problem with our clock a couple of days ago, I changed the time and date but didn't do the year! Thanks again for quick help
