Hello everyone, I installed Windows 8 RTM a few weeks ago. It's not my first time installing it, but it's the first time having two annoying problems:

1) Randomly, the system clock changes time all by itself - to fix it I have to open the time window and sync it with the internet.
2) Randomly, internet connection stops working - to fix I have to run troubleshooting. Windows will find a problem with IP on the "Ethernet" connection and fix it.

How can I permanently solve these problems?

This is what I've already tried:
> Reset
> Virus scan
> Stop/reset the Windows Time service
> Disable/re-enable Windows Time automatic internet sync
> Change time from BIOS
> Change mobo battery

Anyone?

First one I have no idea.

Second one however, try setting yourself a static IP.

Could it have something to do with the timezone configuration?
