Win7 does BSOD upon boot after installation of any Windows Updates

I have a recurring problem with my Win 7 64-bit machine that first occurred a few months ago: any time I allow Windows to install an update, the next reboot produces a BSOD with the error page_fault_in_nonpaged_area.

I have set Windows update to not install any updates automatically -- but nevertheless, it installed a couple of "critical updates" in the last few days without my intervention, so I got another BSOD this evening.

When I get the BSOD, System Repair fails. I have to boot into Safe Mode, run System Restore using a restore point before the update was installed, and then the machine will boot into "regular" Windows.  

Obviously this is not an acceptable situation for the long term.

The most recent STOP codes were:

Problem signature:
  Problem Event Name:      BlueScreen
  OS Version:      6.1.7600.2.0.0.768.3
  Locale ID:      1033

  BCP3:      FFFFF800032C8680

  OS Version:      6_1_7600
  Service Pack:      0_0
  Product:      768_1

I have tried to upload the minidump file but I am unable to do so -- Windows keeps telling me I don't have permission, even though I am logged in as Administrator.  I then tried to get around the problem by zipping the DMP file -- but Windows wouldn't let me do that, either, and then after the zip process failed, the DMP file disappeared.  However, here's the log from the failed System Repair:

Windows Update Service is set to Delayed Start.  The setting for Windows Update in Control Panel is "Check for updates but let me choose whether to download and install them."

Windows is actually installed on my C: drive -- I don't know why it says F:\windows.

ok then so it shouldn't be a services problem then unless the windows update files that perform the updates got corrupted....

if they did then you'd have to repair windows.

My understanding is that with Windows 7, the ability to do a repair install is a lot more limited than with XP -- my computer came with Windows, so I have an OEM Win 7 DVD, and I've read that a repair install cannot be performed with an OEM disk.

BTW, I ran sfc /verifyonly and it found no problems.

have you contacted your manufacturer and asked them for a disk that can?

Do you disconnect your Lacie, IOmega and MyBook external drives when making repair? If not then disconnect all of them except system drive and try repair again.

remixedcat: Thanks for that link.  I do have Kaspersky installed so perhaps there is some connection -- although I have a 64 bit system and it appears the problem referenced in that linked discussion was limited to 32 bit systems.

noxcho: I will definitely try that the next time this happens (although hopefully it won't happen again).

I had a problem like that related to service startup that was causing a BSOD. it was after installing the platform update for server 2008 that is required for IE9.

Here's a minidump file -- it's not from a BSOD that followed a reboot-after-update (that's the one that disappeared, as described in my original post); rather, it's from a BSOD that occurred after trying to repair the system after the BSOD.

One other new symptom: since yesterday, the two USB ports on the front panel of the computer don't work. They don't recognize any devices plugged in (e.g., a USB flash drive, an iPhone), and the iPhone won't even charge from either of those USB ports.  I am getting really tempted to restore my boot drive from a drive image. My fear is that the underlying problem, whatever it is, is present in the drive images on my backup drive, too.

The other action I am contemplating was inspired by the discussion linked above: uninstalling Kaspersky IS, then trying to use Windows Update to bring the system up to date, and then reinstalling Kaspersky.  But I'm just afraid it will be a waste of time, or, even worse, I'll wind up with a totally unusable system. (That shouldn't happen, I know, because I have my drive images -- created with ShadowProtect Desktop -- on an external hard drive, and that external hard drive is copied to a second external hard drive, so I do have a belt-and-suspenders backup that ought to work. Plus I have data backed up in the cloud via CrashPlan. But I just don't want to have to deal with a situation like that if it should happen.)

mabye your OS got corrupted.... if so the best thing is to repair or re-install.

let's hope those backups aren't corrputed!

You have STOP: 0x00000050 BSOD and there are too many suspects. Fact is Windows kernel crashes while trying to access RAM. So I would start with RAM check.
There are several articles by MS but they are not referring to Update installation. So imho, you need to check RAM, then try the suggestion with Antivirus and if that does not help - reinstall Windows from image.

noxcho: I think that makes sense. I will run memtest as a first step and see if it turns up any problems with the RAM.  (I'm almost hoping it's a problem with RAM because replacing that will be easier than reinstalling Windows.) I'll report back.

mitch10021Author Commented:
Some progress:  I ran memtest and it showed no errors. Then I uninstalled Kaspersky Internet Security altogether, and then dared to install a Windows Update.  I decided to try installing SP1 to see if I could successfully get it out of the way, and in fact the installation worked -- I wound up with  a Windows 7 SP1 system that booted successfully. Next I plan to install the remaining updates that are recommended by Windows Update -- but I'm going to install them one at a time, rebooting each time even if not required by the update installation -- to make sure that they don't screw up the system, and if one of them does screw up the system, I'll know exactly which one it was.

Eventually, I have to reinstall my security software, but I'm seriously considering something other than Kaspersky in light of the aggravation it caused.

I recommend Sophos or ESET anti-virus they are both excellent.

I used to use ESET but I switched to Kaspersky about three years ago.  ESET was no longer getting good scores in the various antivirus tests.  But maybe I should reconsider it now.

Have a look on F-Secure antivirus. My personal experience with it is very positive.
