This one appears to have been caused by you Avast antivirus. AV apps are often the source of BSOD's. I would remove it and replace with Microsoft Security Essentials. It doesnt seem to cause nearly as many.


I would also run a system file check to verify and repair your system files

Run a system file check to verify and repair your system files.
To do this type cmd in search, then right click to run as administrator, then
SFC /SCANNOW

read here for more information SFC /SCANNOW Command - System File Checker - Windows 7 Forums

Let us know the results from the report at the end.

There are still remnants (all the drivers) of Avast, so you should use the uninstall utility found here, in safe mode:

AV Uninstallers - Windows 7 Forums

Update your Microsft keyboard driver:

NuidFltr NuidFltr.sys Fri May 08 04:53:31 2009

Update your Microsoft LifeCam drivers:

#6
The LifeCam drivers are still the same. The crashes are either being caused by them or faulty RAM.

To be sure, you could disconnect the camera from the system and reboot. See if any stop errors happen like this. Or double check on updating the drivers again.
 


#7
There's nothing to add, disconnect the cam and if bsod's continue then run memtest overnight:

Cybercore is correct. If memtest doesnt reveal any memory errors you should run a system file check to verify (and repair) your system files
Run a system file check to verify and repair your system files.
To do this type cmd in search, then right click to run as administrator, then
SFC /SCANNOW

read here for more information SFC /SCANNOW Command - System File Checker -


And if that turns out ok run driver verifier.


Beyond that, please run Verifier with these settings:
Using Driver Verifier is an iffy proposition. Most times it'll crash and it'll tell you what the driver is. But sometimes it'll crash and won't tell you the driver. Other times it'll crash before you can log in to Windows. If you can't get to Safe Mode, then you'll have to resort to offline editing of the registry to disable Driver Verifier.

So, I'd suggest that you first backup your stuff and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Win7 Startup Repair feature).

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
NOTE: You can use Low Resource Simulation if you'd like. From my limited experimentation it makes the BSOD's come faster.
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

Reboot into Windows (after the crash) and turn off Driver Verifier by going back in and selecting "Delete existing settings" on the first page, then locate and zip up the memory dump file and upload it with your next post.

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

If that doesn't work, post back and we'll have to see about fixing the registry entry off-line:
Code:
Delete these registry keys (works in XP, Vista, Win7):
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\VerifyDrivers
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\VerifyDriverLevel
