BSOD on startup - PAGE_FAULT_IN_NONPAGE_AREA

Hello All,
I am experienceing the BSOD PAGE_FAULT_IN_NONPAGE_AREA. This occurred suddenly while browsing the web on a known SAFE site (browsed from other machines with no issues).

Once it came up, I have been unsuccessful in getting back into Windows at all. I have tried the following:

Safe Mode (all varieties): Failed
Point in time restore (not image backup): Failed
System recovery repair: Failed
Removed memory one by one to eliminate defective memory: Failed

No matter what I try - the BSOD happens on every boot.

This machine is a
Lenovo W520 - 8GB RAM
Windows 7 Pro x64 - OEM
OS is in original condition except for repair attempts noted above (no reinstall).

There *should* be nothing that was done to cause this that I can recall (no driver installs, no new hardware, etc).

Ideally, I would like to be able to run a repair install over the old OS - like we used to do with XP - but I cannot find that option - It looks like Windows will install in a new dir and rename the old - not the outcome I was hoping for.

I'm hoping someone can lead me in the right direction here - I'm out of my element with Windows 7. Please let me know what other info you might need from me if you have any suggestions.

TIA
Mike

Windows does have a repair install (in place upgrade installation) feature, but you have to get Windows running first. http://www.sevenforums.com/tutorials/105541-startup-repair-run-3-separate-times.html is good information if you have not tried the startup repair three times in a row yet with a restart in between each attempt. Also, you can try manually doing a startup repair with the methods outlined in http://www.sevenforums.com/tutorials/139576-startup-repair-infinite-loop-recovery.html.

Thank you for the suggestions. I tried each of these methods with no joy. I cannot seem to get beyond the boot process despite my best efforts.

Is my only other option to do a reinstall? I would really like to avoid this at all costs. If there are any other suggestions, please let me know.

Thanks,
Mike

Since this is a laptop, the following steps may resolve the boot crisis.

If the above steps do not allow you to boot still, proceed to the next steps.

You may have hard disk errors. Use http://www.sevenforums.com/tutorials/666-advanced-boot-options.html to select Repair Your Computer and get to the http://www.sevenforums.com/tutorials/668-system-recovery-options.html. Then select the command prompt. Do the following:
.etc until you get the message that the volume could not be opened for direct access. For any drives that do not give the message:
"Windows has checked the file system and found no problems"
run chkdsk again as above.

I realize you may only have one disk show up in Windows explorer, but you may have more than one disk through recovery options. This is because the system creates a hidden boot partition (which will be C: in recovery), you may have a recovery partition for your PC that is hidden (which will be D: in recovery), and you will have your primary Windows partition (which may be E: in recovery). A custom PC will likely have at least C: and D: to scan.

It is a laptop.
Battery/BIOS/Power procedure did not help. BSOD.
Ran CHKDSK on C, D, E, as indicated above - No errors, no bad sectors.
Same BSOD.

The only other thing we have not tried (or if you already tried it, you did not mention) was start http://www.sevenforums.com/tutorials/666-advanced-boot-options.html and choose Last Known Good Configuration (advanced).

Yup - I actually did try that - no help.

Sadly, the only option left is a clean install or side by side install. If you want to backup any data, I can walk you through the steps in the recovery environment.

That's what I figured. I pulled off a few folders to an external USB from the command prompt - and I think I got most of the Users folder. If there are any other "best practices" for backing up other data, like my Outlook contacts and email (I had lots saved in folders), I'd appreciate it. Oh, and if you have any idea how I can save my iTunes playlists as well as my Picasa "faces" library, that'd be just swell!
Thanks!
Mike

iTunes playlists are saved in users, correct? What about Picasa? I would backup your whole users folder. Use the following method.

To backup via the Windows 7 installation disc, start the Windows installation with your external drive plugged in and do the following steps.

1. Press Shift + F10 when the installer loads.
2. Search for the drive with the Windows directory on it. Type the following commands into the prompt:
   • C:
   • dir
   • D:
   • dir
   • e:
   • dir
3. etc. until you see Windows toward the bottom of what is listed by dir.
4. Mark down the drive letter that has Windows on it.
5. Find the external drive using the same drive letter, dir procedure (you may get the message The device is not ready for drives that do not exist)
6. Once you find the external drive layout you are familiar with, you can back up your files using the following commands (in my commands, I assume the Windows drive is C: and the backup external drive is F:, so use the appropriate drive letters for your case).
   • robocopy /s /r:5 /w:0 /xo /xj C:\folderNameToBackup F:\backupFolderName
   If you only want to back up a subdirectory, use
   • robocopy /s /r:5 /w:0 /xo /xj C:\topFolder\folderNameToBackup F:\backupFolderName
7. In the above, folderNameToBackup is the name of the folder you want to make a backup of. backupFolderName is the name you want to use for the backup. For example, if I want to backup the whole users folder, I would use:
   • robocopy /s /r:5 /w:0 /xo /xj C:\Users F:\backupUsers
   or to backup just my user
   • robocopy /s /r:5 /w:0 /xo /xj C:\Users\Mike F:\backupUsers\Mike
