internet browser certificate problem

hey guys, just some time ago, im receiving this message on screen that the certificate is expired or invalid in my web browsers, whenever I browse some log in websites like yahoo mail and facebook, the page display is somewhat incomplete, the pictures etc are missing, only word texts are shown, also in yahoo mail, whenever I log in, its just a plain text of columns like inbox, sent items etc, but whenever I click one (lets say inbox for example, nothing is happening) I saw that the url part of my browser has a red part, saying that there's a problem with the security certificate, I did a uninstall/reinstall of chrome and firefox browsers (I normally use google chrome browser) but still the same problem.

Can you guys please advise? Thanks

 

is your cmos battery dying. and is your clock set to the correct time.
my old clevo beeps every time i turn it on and i have to manually set the clock otherwise i get unsecured certificates on every page.

 

MrDJ is right, make sure the date is correct.

 

just updated the clock and date in my country in real time, still no effect

 

Did you make sure your BIOS and uptodate? And is your CMOS battery ok? Also did you make sure your windows is up to date? There was some time back about updates to the time/region that was update and that could also be the cause??

 

if the time was out then it would not do the normal windows updates.
once i reset my clock a few hours later i get the icon to update.
