I have high DPCs when the POWER service is running. If I turn it off, the DPCs go back to normal.
Why? What is this trying to run that is causing this?
OK, U can't tell. How can I troubleshoot this now that I know the culprit???????????

Then again, someone must have found and fixed this already.

Not familiar with this rare occurrence, but maybe this will help??

that in fact is the only program I am aware of to monitor DPCs. Been using it for a while, but when I went there I noticed it had been updated. thx
 
FYI - I figured it out.

If I shut off the POWER service high DPCs are eliminated. However, not having it on is not an option.
I need it otherwise it won't go to sleep - so what causes the high DPCs.

APPARENTLY, when it is active it is constantly checking status - that seems to be THE thing that slows any windows system down.
SO, I went back and set the power option to HIGH PERFORMANCE - from BALANCED -- 20 min later I have had NO high DPCs.

the end.................
