Windows 7: Right-click Windows 7 explorer crash, 'Power' & audio service issue

Right-click Windows 7 explorer crash, 'Power' & audio service issue

Hello, I am new here. I have been having problems with Windows 7 explorer constantly crashing and restarting whenever I right-click on or open any files and folders, search in the Start Menu search box, opening My Computer, Control Panel, etc. In essence, it is limiting most of the interface. I was able to pinpoint the problem using Safe Mode and msconfig to the 'Power' service (C:\windows\system32\svchost.exe –k DcomLaunch). And once I disabled the 'Power' service, everything seems to be fixed.

However, disabling the 'Power' service will disable audio service for the system. To fix the audio service, I tried changing the Power management, reverting back to previous restore points, updating the audio device drivers, trying to enable the Windows services in services.msc for 'Remote Procedure Call (RPC)', 'Plug and Play', 'Multimedia Class Scheduler', 'Windows Audio Endpoint Builder' and 'Windows Audio' to activate sound again, but 'Window Audio' depends on 'Windows Audio Endpoint Builder', but 'Windows Audio Endpoint Builder' seems to depends on the 'Power' service. And I can’t activate the ‘Power’ service again without crashing Windows explorer. How do I go about fixing this issue? Can I replace the ‘Power’ service files? Or update them? And help is much appreciated. Thanks in advance!
