random BSOD and sometimes freeze on shut down

Windows 7 Home Premium 64 bit (original OS when i bought the notebook, so its OEM)
age of hardware and OS about 1-2 months
dell inspiron 14R (inspiron N4010)

just got BSOD 2 days ago once, and today (twice)
at the first bsod, suddenly my keyboard unable to use, so i restart, and then the bsod happened.

BSOD occurs when start up the windows (after login screen)
the BSOD is not always happened

also sometimes, when i safely remove my removeable devices (hardisk or USB flash disk), they weren't removed from the system, but i cant acces the drive
after that, when i shut down or restart the notebook, it hangs up in the 'shutting down' screen, so i have to hold the power button to stop it
this 'unable to remove from system' problem happened about 1 weeks ago.

please help me guys. thanks for your answer/ help.

so i upload the dump manually and the event that i found as critical in my event viewer

Can you please search for it, as I have never seen a case where it was not created in the documents folder before. If you can't find it then run the application again, this time double-checking that you are running it as an administrator.

usbvideo.sys is a Microsoft Driver, and therefore unlikely to be the true cause here.

Please update your webcam drivers from your laptop manufacturer: Welcome to Home User Support

If you have an external webcam update the drivers from it's manufacturer too.

A few other items to take care of:

Uninstall Avira

While I do not think it was the cause in this case, stranger things have happened.

Avira Uninstallation instructions (follow these exactly): Avira Solutions - Knowledge Base Problem Details

Install MS Security Essentials --> http://www.microsoft.com/Security_Essentials/

Uninstall McAfee

For the same reason as above

Remove McAfee using the McAfee Removal Tool (MRT) -

MRT --> http://download.mcafee.com/products/...tches/MCPR.exe

Download the MRT & save to desktop. Boot into SAFEMODE (NO Networking) - tap F8 key during boot-up. Then go to desktop, RIGHT-click on the MRT icon and select Run as Administrator.

When complete - re-boot.

Then reset the Windows Firewall to its default settings -
START -> type cmd.exe -> right-click -> run as administrator -> type netsh advfirewall reset press enter
