If this happens with ASIO drivers running, try switching the OS "Processor Scheduling" to "Background Services" via Control Panel -> System ->
Advanced -> Advanced (again, from the tab).

Might be slightly different for the various Windoze offerings, a Bing should bring up particulars on how to get to it.

And - If it is already set to Background Services, as regards the net published Tweaks for DAWs - try turning Background Services OFF then.

This would be an interesting experiment to perform regardless of result, would be good to report your findings in this regard. To include make and model of Sound Device and whether or not you are using Native ASIO or one of the converters.
