Blue Screen on Win 7 64 Bit

Every few days I get a blue screen of death on my Windows 7 Enterprise computer
Here are the details

A problem has been detected and Windows has been shut down to prevent damage to your computer.

Modification of system code or a critical data structure was detected.

If this is the first time you've seen this stop error screen, restart your computer.   If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed.  If this is a new installation, ask your hardware or software manufacturer for any windows updates you might need.

If problems continue, disable or remove any newly installed hardware or software. Disable the bios memory to remove or disable components, restart your computer, press F8 to select Advanced Startup options, and then select Safe Mode.

Tuff one to crack but these are the files that is creating bsod

usbehci.sys
usbscan.sys

Its not necessarly these files are creating the crash but the devices attatched to usb might be crashing the computer. So check all your usb devices. Make sure you have installed all the updates drivers for your devices like printer , scanner, usb devices, etc.

Would recommend disconnect all usb devices and check whether you get the bsod. But first update printer and scanner drivers.

I just recently installed a web cam which seems to have started this and the web cam does act of sometimes. I will try that one first by unplugging it and see what happens

What do you use to analyze the memdump files?

So its seems like the problem is with the web cam. Dumps are pointing to some kind of usb device or  usb spyware.

1. Remove webcam and uninstall its drivers
2. Update chipset drivers for your motherboard - eg Intel
3. Find newer webcam drivers (and verify it's formally supported on Windows 7 64bit!)
