Internet Explorer Message: The security certificate has expired or is not yet valid

by Mitch

in Internet Explorer

If you are getting a message popping up on certain web sites when using IE that says The security certificate has expired or is not yet valid, you will want to check the date and time your computer is set to.

Just double-click on the time in the lower right corner on the Taskbar and set the time correctly. Be sure to check the time, month, date and the year. As soon as it is corrected, this will usually fix this issue.

When you correct the date/time setting and that resolves your problem, you may ask “how did the date/time suddenly change?” The most likely answer is that you CMOS battery on the motherboard is failing. You probably need a new battery, otherwise everytime you lose power to your computer, your date/time will be corrupted again.
