The link you posted is to shortcuts, not the crash dump files themselves. You'll need to upload the crash dump file (it'll be large).
In my experience a watchdog issue is generally the graphics driver. You should look in the Event Log and see what it says. It may tell you which driver is having the issue.
Irrelevant you should follow the standard process and clarify to us that you have:
- Latest update for the driver(s) in question
- If it just started happening then what changed on the machine and have you tried to revert back
- Latest windows updates (win 10?)
