Windows 7: BSOD from drivers - netgearudsmbus.sys and/or clwvd.sys

BSOD from drivers - netgearudsmbus.sys and/or clwvd.sys

Good day I am looking for assistance on how I can clear a persistent BSOD problem where my HP Elite has been experiencing intermittent BSODs over the last month.

The PC was too unreliable so I restored from a month earlier image I had cloned with Norton Ghost.

That image was more stable so I activated MS Driver verifier which then BSOD'd on clwvd.sys, which as far as I can tell is the driver for YouCam.

I removed the YouCam software and driver verifier then BSODed on netgearudsmbus.sys. This I believe is the driver for netgears USB control software which allows connection to a USB printer connected to my netgear router.

I rebooted the PC several times with driver verifier running and neither of the two "faulted" drivers present and received no BSODs.

So I updated the netgear software to its latest version (driver 1.74.27) and reinstalled YouCam v 3.

The next reboot had a BSOD with APC_INDEX_MISMATCH.

The roboot after that loaded fine. The PC is currently running, but will BSOD if I turn driver verifier on again and may of course do so if the underlying problem persists.

I have attached as advised in the BSOD instructions the dumps from the diagnostic tool. There may be 2-3 some older crash dumps from earlier years which are not relevant to this in the zip file but I dont have the tools to read and sort these out.

thank you
Mark P

Security App
Crashes indicate Norton being a possible cause. Remove Norton and replace with Microsoft Security Essentials to see if it provides more stability. Uninstallers (removal tools) for common antivirus software

Microsoft Security Essentials and Malwarebytes are recommended from a strict BSOD perspective. They do not cause blue screens on the system as other AV products do.

Microsoft Security Essentials, Free antivirus for windows

Malwarebytes Anti-Malware Free

warning   Warning
DO NOT start the free trial of MalwareBytes, unselect that option when prompted.


Tip   Tip
Update and make full scans with both separately.

Virus check
Scan your system with the following:

Kaspersky TDSSKiller - How to remove malware belonging to the family Rootkit.Win32.TDSS (aka Tidserv, TDSServ, Alureon)

ESET online scanner - One-time virus scanner free with ESET online scanner

Check for a BIOS update:
Code:
BIOS Version/Date	American Megatrends Inc. 5.15, 25/06/2010
Start up
Keep less stuff at the start-up. Only anti-virus, this helps avoid driver conflicts and improves time to log in to windows.
