Okay this is quite a complicated BSOD.

Firstly:

*** WARNING: Unable to verify timestamp for [COLOR="Red"]CMUACWO.sys[/COLOR]
*** ERROR: Module load completed but symbols could not be loaded for [COLOR="red"]CMUACWO.sys[/COLOR]

I personally have never heard of this driver. After a Quick Search online i was able to find this.

Installation Path	ID:0421939 C:\Windows\system32\DRIVERS\CMUACWO.sys
Description	 C-Media USB Audio Class Driver
Version	 7.0.0013.219 built by: WDK_6001.18001
Company Name	 C-Media Inc.

I would like you to run Driver Verifier.

As i said there are multiple things flagging up in the DMP's. We will take one at a time.

Thanks for your help. I've enabled driver verifier, will check it once I come back home.

CMUACWO is the driver for Schiit Audio Bifrost D/A USB converter. It makes sense now as I started getting blue screens roughly at the same time as I installed it.

Okay brilliant, because we now know what is causing the BSOD we don't need to run driver verifier.

Please uninstall and reinstall the problematic driver.

Keep m posted, I'm off to work now but i will be able to check on my lunch break.

Hi,

Sorry I didn't have a chance to re-install the driver. Will do it sometime this week and report back.
Thanks.

 

[h8dk97]

Ok
I've reinstalled the driver, will give it a few days and report back

Re-installing the driver didn't help, my computer still reboots occasionally. Is there anything I need to do to further investigate?
Thank you.
