If you haven't done much on your system, just refresh/reset Windows. In case you didnt know, refresh preserves your user account, files, and metro apps, so it wont be that difficult to setup afterwards.
The thing is, I had that kind of issue (100% USB xHCI active time), and I couldnt find nothing to solve the problem.
