Please Help!!--Right-click crashing Windows 7 explorer, 'Power' service, audio service problems RRS feed

  • Question

  • Hello, 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!

  • Although you sound convinced it’s the Power/Audio services, I wonder if something else is playing a part in the issue.

     

    Similar problems are sometimes caused by a third-party extension. ShellExView can be useful to see which shell extensions have been introduced into Explorer. Read about it then scroll down near to the bottom to download the x86 (32-bit) or x64 (64-bit) version here http://www.nirsoft.net/utils/shexview.html

     

    When you run it, click on the column labelled Company to alphabetically sequence the entries. You have to assume that the Microsoft entries are bona fide, so concentrate on the third-party entries. Is there anything listed that is either unnecessary or unknown? If so, highlight it and click the red spot (top left) to disable it. There shouldn’t be too many of them but you may find it easier to disable them all, then re-enable them (green spot) one at a time and try Explorer until the culprit is found.
