Windows 7: BSOD UNEXPECTED_KERNEL_MODE_TRAP (7f)

BSOD UNEXPECTED_KERNEL_MODE_TRAP (7f)

Early this morning (while I was asleep) my computer (WIn7 Pro 32-bit) experienced a UNEXPECTED_KERNEL_MODE_TRAP (7f) error, reboot, minidump, and full dump. The only applications that are active (without user input) overnight are Firefox (I have a NOAA radar image running and auto-updating), Thunderbird, and BOINC SETI (to use unused cycles). I am not sure for what to search in the minidump or full dump.

Code:
BugCheck 7F, {d, 0, 0, 0}

Probably caused by : netbt.sys ( netbt!NbtQueryFindName+fb )
Code:
Usual causes:  Memory corruption, Hardware (memory in particular), Overclocking failure, Installing a faulty or mismatched hardware (especially memory) or a failure after installing it, 3rd party firewall, Device drivers, SCSI/network/BIOS updates needed, Improperly seated cards, Incompatible storage devices, Overclocking, Virus scanner, Backup tool, Bad motherboard, Missing Service Pack
It seems to have been caused by a General Protection fault.

Your Intel PRO/1000 Adapter NDIS 6 deserialized driver seems to be a possible cause, please update the driver from here - https://downloadcenter.intel.com/Default.aspx

Windows 7 doesn't require any programs which make changes to the operating system and registry, these programs tend to cause problems by modifying and deleting files.
Quote:
Windows is a closed source system. Developers of registry cleaners do not have the core code of Windows 7 and are not working on definitive information, but rather they are going on past knowledge and experience. Automatic cleaners will usually have to do some guesswork.

Modifying registry keys incorrectly can cause Windows instability, or make Windows unbootable. No registry cleaner is completely safe and the potential is ever present to cause more problems than they claim to fix.

Registry cleaners cannot distinguish between good and bad. If you run a registry cleaner, it will delete all those keys which are obsolete and sitting idle; but in reality, those keys may well be needed by some programs or windows at a later time.

Windows 7 is much more efficient at managing the registry than previous Windows versions. If you run any other registry cleaner and do not know precisely what you are doing, you will have problems down the road. There are no gains to be had from using a registry cleaner and the risk is great.

Running multiple real-time protection programs can cause serious conflicts and crashes. Please note this program does cause BSODs.

I am confused. That Intel URL told me:

Product Detected Intel(R) 82566DC Gigabit Network Connection
Current Driver Installed 9.13.4.10
This device is unknown or unsupported. Please contact the manufacturer for possible updates. More information>>

I did many searches on the Intel web site for e1e6032.sys, and I found that the latest version is 9.16.10.0. I tried a Win 7 install, and nothing was installed because nothing fit. The Intel site says that e1e6032.sys is for my controller (82566DC) but for Vista and Server 2008 32-bit. I tried to install a Vista driver set, and it installed. But it did not update e1e6032.sys. When I looked at the properties of e1e6032.sys, it shows 9.13.4.10 and a 7/13/2009 date. When I then go to the Intel auto-search utility, it shows me that e1e6032.sys is now at 9.16.10.0 . This confuses me. Note that I did not reboot after the driver install, and a search of the \Windows directory shows all copies of e1e6032.sys with the 2009 date. A Google search for "e1e6032.sys" showed versions that I could download, but they were LATER than 9.6.10.0, and I am not sure that trust a driver download from "any old" web site. I will reboot now.

That's strange, and don't download any drivers from any other website apart from the manufacturer or your motherboard support page. What's it like after reboot?

After the reboot:

\Windows\system32\Drivers\e1e6032.sys 7/13/2009 5:02PM 207kb

The Intel driver page Intel® Driver Update Utility for wired networking shows (after I run the applet):

Product Detected Intel(R) 82566DC Gigabit Network Connection
Current Driver Installed 9.16.10.0
This device is unknown or unsupported. Please contact the manufacturer for possible updates. More information>>

I am sure that it said 9.13.4.10 before I did any installs this morning.

The driver file:

e1e6232.sys 9.16.10.0 10/30/2012 4:22AM 227KB

I believe that this 6232 file is the one used by Windows 7, and the auto-detect utility finds it.

What I do not understand (and I do not know the internals of Windows 7), is how e1e6032.sys is implicated in the dump, when that driver is supposedly not used in Windows 7. I would like to upgrade that driver file to the latest version mentioned on the Intel web site, but I have found no way to download that file from Intel. I downloaded DriverVIew from Nir Sofer, and that utility's output lists e1e6232.sys but not e1e6032.sys .

I also do not understand why the Intel auto-detect applet claims that the device is unknown or unsupported. I did write a lengthy comment on the Intel web site, and I included my name and e-mail address. I have no idea if Intel will contact me.

Did you upgrade to Windows 7 or install Windows 7?

Have you tried your motherboard support page?

Hopefully Intel will contact you.

This was a fresh install of Windows 7 Profressional 32-bit. I never do an upgrade install because 1) I want to preserve my old system in case something happens, and 2) where I used to work, the Windows support staff said that upgrade installs are risky.

My motherboard is an Intel DP965LT.

Support page for your motherboard - Support for the Intel® Desktop Board DP965LT

According to this, your motherboard doesn't have Windows 7 support.

Some questions and comments. Intel says that my board does not have Win 7 support, but other posts on SevenForums say that there is no problem with that board and Win 7. Intel has not responded to my query about drivers, and when I tried to ask a question on the Intel support page, the box was one line long, and it did not accept more than about 150 characters, so I could not ask a detailed technical question.

When I use a utility such as UpdateMyDrivers to see if there are newer versions of the drivers I have installed, I see reference to Intel drivers 9.3.1.1009 (9/11/2012), and my drivers are 6.1.7601.17514 (6/21/2006). I can do Google searches and find many sites that have the 9.3.1.1009 drivers for download, but I cannot find those drivers on the Intel web site, so I have no idea if those 1009 drivers are genuine. And, as I mentioned in a previous post, the Intel driver identifier tool says that my devices are "unknown or unsupported". 19 of my 24 outdated drivers (according to UpdateMyDrivers) are Intel.
