Date Time Resets/Certificate Error (lol.launcher.exe)

Hey,

I bought a gigabyte m/b 2 months ago and for the last 2 weeks date and time randomly resets to 1/1/1900. After a few minutes a certificate error comes up (when I play League Of Legends). Here is the picture with the certificate. (https://www.dropbox.com/s/l4e36h27tbcjzu1/Untitled.png?...)
Whether i install it or not, or fix the date time, once it happens it changes every few minutes.

I even deactivated the automatic date/ time sync with the internet.
The CMOS battery is new. But i even changed it and nothing was solved!

Is there anything else i can do?
Windows updates are all installed.
When I press the issuer statement, the following site comes up : https://www.digicert.com/ssl-cps-repository.htm
Also updated the IE!

I have already contacted the Riot Games and they have no solutions (what a surprise!).
This happens only when the LoL Client is on whether I am in a game or not.

Regards!

I had Gigabyte AppCenter installed and running when I was facing the same random reset clock problem. One solution is to open the application (located in taskbar) and go to Settings (top right item). Then uncheck Auto Time Sync option. Another solution is to completely remove AppCenter from running when Windows start. Hope this helped, lil_gusta
