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!
