Invalid Security Certificate. BIOS Date Changed
Posted on February 8, 2012
A friend called me a few days ago with an issue with logging in to his yahoo mail account on his new Windows 7 computer. He really could not explain what was happening other than he can go online and surf the web, but he just could not log in to get his mail. He also noticed that AVG atni-virus was not updating and giving an error about the clock. Seemed like a simple fix, just update windows time. He tried that and it that failed no matter which time server he selected.
When I arrived the computer was working fine. I did not see anything out of the norm. Until he tried to log in to his yahoo mail. Internet Explore started an infinite redirect loop at the yahoo log in page. The page just flash as the page redirected onto itself. Final I hit the stop button in the browser and the page displayed your browser did not redirect you to the proper page please click here. When I clicked the redirect link I got an invalid security certificate. I thought how or why would Yahoo have let their certificate expire.
The next step was to check things out in Google chrome or Firefox. Neither where installed, so I went to Google to down load the Chrome, everything worked until the download was suppose to start. I got nothing. Tried to download Firefox with the same results.
The next thing I checked was for a blown capacitor, so I opened up the box and all the capacitors looked fine. Once I put the computer back together I went in to the BIOS. Check the time and the time was dead on. Then I saw the problem, the time was correct but the BIOS time was set to 2080. I thought that was really strange, since I have received an email a few days earlier and the date sent was 2080. The date and time is a very important component to your computer.
I change the BIOS date to 2012 and booted Windows 7. At that point everyone was happy. No more invalid certificate errors and Google chrome and Firefox both downloaded as expected. AVG updated and we ran a full scan and it came up clean. On a side note you should always have more than one web browser installed. Even if you only use Internet Explorer, having an additional browser will allow you test the other browser.
If you have seen this issue please let leave me a comment. I would be interested in knowing if there might be some issues with newer BIOS jumping to year 2080.
