Windows Audio highcpu

[TheDSSlayer]

Recently all of a sudden i been getting high cpu usage from "Service Host: Windows Audio Endpoint Builder and when i check my sound on the system there is headphones constantly flickering on and off, i own a headset but its running off as a usb audio device. when i try and eventually click on the flickering headphones and disable it i get a message saying "Windows Shell Common Dll has stopped working. I have never had this problem before and it's frustrating as it's completely taking up my CPU. I tried a factory reset on my pc in a desperate attempt to get rid of the problem but it still persists. Screenshot Links below showing problems.
I hope someone out there can really help me as i really can't afford to get this serviced by a technician atm. Thanks

It seems i disabled it from task manager and it came back almost instantly but after a few times it stayed off, but when i restarted my pc the problem still occurred!!
