New server Windows clock losing time

same here!

As soon as the problem appeared a week ago I changed the cmos battery, but it persisted. I ran multiple virus scans with different sofwares but found nothing. sfc /scannow said the system files were ok.. and yet the clock kept freezing or jumping backwards.

then I realized the clock in the bios was freezed. I thought of an hardware problem but before calling Asrock I searched the internet and found this: https://stackoverflow.com/questions/18995923/windows-8-8-1-system-clock-changing-randomly-while-powered-on-and-in-use

I tried an hard cmos reset (removing the battery) and the bios clock restarted!! But it stopped again when I loaded the bios settings I previously saved. So I had to reset again an manually change all settings back to how they were, and now it works.

At the technet-windows-forum there is a thread which shows the same problem. Because you've tried just software-solutions, maybe you have more luck with the hardware.

1. Shut the PC down
2. Pull the plug out of the socket
3. Wait a few seconds
4. Boot PC
