System clock changes randomly and often, causes applications to crash

I've been having a problem lately where I would be using a moderately resource-intensive application and it would crash completely, and the system clock in the lower right-hand corner would change. This happens especially when playing games, but it also happens whenever a BSOD occurs. I've tried a few things, like restricting application access to the system clock, but nothing worked. This has only happened once before, but now it's a lot more frequent. I'm not sure what else to post here, as this is all the information that I have.

Any help would be greatly appreciated.

Try changing the NNTP server to a location near you:
Configure Internet Time (NTP) options in Windows 10

NIST Internet Time Service

See important note 3 in the second link:
3. The generic name time.nist.gov will continue to point to all of our servers on a round-robin basis, and users are encouraged to access the service using this name.

Also might want to look at replacing the button style CMOS battery on the motherboard - one function of that battery is to keep the system clock running.
