BSOD Win7 x64 BugCheck 9F

Hi, first time post. I hope to get help with a reoccurring crash. Here are my basic PC stats:

* Windows 7 Professional x64
* Original OS was Windows 7 Home Premium x64, has been upgraded with Windows Anytime Upgrade
* The original OS was OEM
* Hardware is about 1 year old
* OS is about 1 year old
* System is a Dell Studio XPS 8100

The crash symptoms are as such:
* it only occurs when I do a sleep (and perhaps also a hibernate, not sure)
* it is intermittent, but more often than once per month
* the computer enters sleep correctly, but once in sleep it occasionally will reboot itself due to a bugcheck 9F, typically after several hours
* the computer can exit sleep properly if it has not already crashed
* the computer is stable with no other types of crashes; that is, if I avoid the sleep and hibernate features I do not have any crashes or problems.
* the computer has been patched fully on Windows Update
* despite the informational message in the perfmon report to the contrary, I have Microsoft Security Essentials running and up to date
* I have no other symptoms of viruses or malware

I tried loading the dump in WinDbg which implicated usbccgp.sys, but do not know how to proceed from there or whether that driver is in fact the root cause.

I would greatly appreciate any help since I would love to use the sleep feature of my computer!

Your Logitech webcam driver is the cause, please update it

The driver it uses it obsolete

Thanks! I will try that and post back here if I do not experience any problems after a week or two.

Also, I would like to learn how to make these determinations. I know you don't have time to tell me all there is about reading memory dumps, but do you have any quick tips about how you were able to find the culprit so quickly? If you used WinDbg, what command and result pointed you toward the Logitech driver? Thanks!

In WinDBG using the !analyze -v command the faulting driver, lvuvc64.sys belonging to the logitech webcam driver was identified as the cause of BSODs

Just posting back that this was the problem, I uninstalled drivers and haven't had the problem since. Solved! Thanks!!
