Vista - Rundll32.exe error = No Sound!

**wapwap** · 10-03-2008

Hi there, I've just returned to these forums after a long spell away following a total system failure requiring reformatting. I got so sick of my pc I stopped using it for a few months. Now I've reformatted (AGAIN!) and I'm starting to have problems again...

I have no sound and when I click on the Sound icon in the Control Panel I get a rundll32.exe error message.

Code:

Problem signature:
  Problem Event Name:    APPCRASH
  Application Name:    rundll32.exe
  Application Version:    6.0.6000.16386
  Application Timestamp:    4549bb52
  Fault Module Name:    mmsys.cpl
  Fault Module Version:    6.0.6000.16386
  Fault Module Timestamp:    4549d2a3
  Exception Code:    c0000005
  Exception Offset:    0000000000005371
  OS Version:    6.0.6000.2.0.0.768.3
  Locale ID:    2057
  Additional Information 1:    e094
  Additional Information 2:    07a0e9595b24741d2d20ba6b23d695c9
  Additional Information 3:    6dc9
  Additional Information 4:    b9430fc1bfd395cd40720d6c0f75b33e

I've been to the Asus website and downloaded and installed the latest audio driver (CM6501) for my mobo but all that's done is change the type of device installed to C-Media from PnP in the device manager. The C-Media sound config says there's no device installed.

If it's relevant I also cannot open the User Accounts settings under Control Panel or open Display Settings. I also have an account missing from my logon screen.

Can anyone help please? Many thanks!

Hi Wapwap,

Have you tried uninstalling the audio devices, rebooting and running a System File Check?

Heres a guide on using SFC

System Files - SFC Command

I had previously tried disabling my sound device and rebooting but that didn't work. I just tried to uninstall my sound device but now my device manager won't open!

I get the following message in the device manager window:

MMC Could not create the snap in. The snap in might not have been installed correctly.

CLSID: {74246BFC-4C96-11D0-ABEF-0020AF6B0B7A}

Hello wapwap,

Strange you are getting so many errors soon after a clean reinstall.

If I couldn't run the SFC command , I would try a repair install - unless Steven has a better idea

Repair Install For Vista

Hope it helps

Thanks for the advice, I'll try a repair install and if that doesn't help I'll reformat....again!

**UPDATE**
Help!!! I did a repair install but now for some reason my copy of Vista isn't authenticating as genuine when it is! I waited till my pc booted after the repair install before putting my key in but now I have a message in the bottom right of my screen saying THIS COPY OF WINDOWS IS NOT GENUINE!

The problem I had with sound is fixed, but it seems kind of irrelevant now compared to a genuine copy of Vista losing authenticity for some reason.

**2ND UPDATE**
Did a phone activation then rebooted. The "...not genuine" message has gone from my desktop. Appears to be fine now.

Thank you for all your help!
