[AC Question]

Continuous pop up until phone goes into black screen.

[B. Diddy]

Welcome to Android Central! Which phone?

t's hard to find anything about it, but from what I can gather, it has to do with wi-fi. I found this little nugget in a firmware FAQ from Actiontec, which makes Screenbeam, a wireless display:

(Q) What is DCM?
(A) DCM stands for Different Channel Mode. DCM is a function of the wireless network adapter and its driver. It enables the system's wireless adapter to simultaneously operate multiple connections on different wireless channels, and supports applications such as Wi-Fi infrastructure and Wi-Fi Direct.

However, this doesn't mean that I know for sure why DCM Provider is stopping. I'd suggest a cache partition wipe to start with, which won't erase any personal data.
