Windows 7: BSOD when removing USB 2.0 cable or shutting down, ntoskrnl.exe+7cc40

ivanheneghan · 21 Sep 2011

Hi there,

I recently received my new rig (Alienware M14X), and have had persistent problems with it.

The main issue is that I get a BSOD every time I plug out the USB 2.0 cable running from my laptop to my Dell monitor, or sometimes when shutting the machine down.

I've tracked the error back to an issue with ntoskrnl.exe (+7cc40), but I also know this is quite a general issue.

I have tried multiple solutions (driver updating, etc), and System Restore seemed to solve this for a while, but it's happening again.

I've attached my .dmp files, and would love if someone could help on this.

It's a hardware problem concerning the drivers for a camera connected to the computer made by Creative maybe a webcam or something of that nature. If you have a webcam please update the drivers or software for it from here: Creative Worldwide Support

Please fill in the rest of your system specs using the tool attached to this thread it will help us get better help for you.

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 0000000000000000, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, bitfield :
    bit 0 : value 0 = read operation, 1 = write operation
    bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: fffff8000309ad75, address which referenced memory

Thanks for the reply, Seth!

Based on your information, I've done some digging. There are two webcams in the rig - the webcam integrated into the laptop itself, and the webcam integrated into the monitor.

The latter seems to be the culprit - the monitor is a Dell SP2309W, with an integrated Creative Technologies WebCam. However, I've hit a wall with this.

I've updated the monitor driver to the most up-to-date Dell SP2309W driver. Looking at my Device Manager, there are two Imaging Devices: an Integrated Webcam with a driver from 2006 and a Monitor Webcam with a driver from the same time. Originally, the Monitor Webcam driver was a Creative Technologies one, but I tried updating, then uninstalling and updating, and I got the BSOD each time. Now, it seems that driver has reverted to a standard driver (the 2006 one is now the same for both devices, leading me to think they both are referring to the same device, perhaps?)

Any advice on next steps - how to remove the devices completely while avoiding a BSOD? Where to find the most up-to-date driver for the monitor webcam (nothing on the Dell or Creative websites that has helped so far)?

Regarding the specs, here you go:

Intel(R) Core(TM) i7-2720QM CPU @ 2.20GHz
Alienware M14xR1
InsydeH2O Version 1.0 A04
8.00 GB
WDC WD7500BPKT-75PK4T0
(1) Realtek High Definition Audio (2) Intel(R) Display Audio (3) Monitor Webcam (4) NVIDIA High Definition Audio (5) NVIDIA High Definition Audio (6) NVIDIA High Definition Audio (7) NVIDIA High Definition Audio (all under Sound Card)
(1) Intel(R) HD Graphics Family (2) NVIDIA GeForce GT 555M
Microsoft Windows 7 Home Premium 64-bit 7601 Multiprocessor Free Service Pack 1

Further help would be really appreciated!

Thank you so much!

Ivan

PS As a quick update, I just updated the Monitor Webcam driver to a Creative Technology driver from 2008, version 1.1.2.804 (which what it was before I started trying to uninstall it). This seems to be the most up-to-date driver available... Drivers Informer: Monitor Webcam overview .

Go into device manager and disable the one in the monitor (type device manager in start>search bar) and look under cameras and such in device manager and disable one of the two I guess and see if the problem goes away if it doesn't then disable the other and enable the disabled one and see if that helps. If that doesn't do it then disable them both. If you plan on using the webcam make sure which one it is you want to use then stick with that one. I'm sure that if both are enabled it is causing a hardware conflict.

Also try here for your driver updates: Drivers & Downloads

Thanks Seth. After more investigation, the "Integrated Webcam" is the one in the laptop (which is also a Creative webcam), while the "Monitor Webcam" is the one in...well...

I've tried disabling both in turn in the Device Manager - the webcam in the laptop disables just fine. However, trying to disable the monitor webcam (or uninstall the drivers) just results in the BSOD again.

Is there anything to be done? I'd hate to think that whenever I use my monitor, I'll just have to deal with a BSOD when I plug out, or remove the cable and not use it, meaning I can't use the monitor as a USB hub anymore...

Do you have a safely remove hardware icon down by the clock? If so are you safely removing the monitor? What I mean is are you clicking down there on the usb cable icon with a green check mark and then safely turning it off before unplugging it?

ivanheneghan · 23 Sep 2011

No, no "safely remove" icon appears when the monitor is plugged in - only for USB keys and my external hard drive.
