failure when upgrading Win 10 from Win 7 with message "PAGE_FAULT_IN_NONPAGED_AREA"

The error is generally a memory error caused by memory hardware or memory corruption by software.

The only thing I could think of is to try System File Checker on the Windows 7 machine. Open cmd.exe with Run as Administrator and run SFC /SCANNOW twice. Allow to complete, shut down, restart, and try installing Windows 10 again.

If that does not work, you may have to back up everything, install Windows 10 and accept the option to Keep Nothing.

You must have some software or other damage that is preventing the update.

It's also caused by security software which prevents changes to the Windows Kernel so if you have any form of security suite installed with your AV it's worth considering installing that before the Win10 upgrade.

I tried John's method, although I ran "SFC /SCANNOW" only once (with no error). I also uninstalled my anti-virus software following MASQ's suggestion. However, the same error happened. Maybe I should think of reinstalling my Win 7...

If you are thinking of reinstalling Windows 7, backup, try the Windows 10 upgrade and Keep Nothing. This will be essentially a Windows 10 fresh install.

This error is typically caused by either an errant AV program or a bad device and/or driver...

You might also have a virus or rootkit that causes issues... Try running a good antimalware scan (like MBAM, or Roguekiller or TDDSKiller)...

Suggestions:
1) Uninstall your AV program
2) Unplug ALL devices save for keyboard, mouse... If using multiple monitors, remove all but one... If using a special video card, try using the internal one instead...

You might try giving additional info as to the make/model of your PC, which AV program you run, and list any hardware installed so we can better isolate the issue...

This condition is usually repaired by upgrading to WIN 10 with the basic configuration, and THEN re-adding new versions of the needed hardware and/or software drivers...

Thank you, guys. @n2fc, I assembled parts of different makers to make this PC. For example, the motherboard is from MSI, the video card is from MSI and I have SSD from OCZ and Samsung... So, I gave up on troubleshooting the problem for the upgrade failure of the old system. Instead, I installed Windows 7 from the DVD as well as all the drivers and utilities. Then I did all the necessary Windows updates. Then I see the upgrade to Windows 10 icon at the corner and I am upgrading. If it fails this time, I may take @nobus's advice to check the memory. I have four 8GB memory sticks.

Hi guys, I installed Windows 7 and all the drivers and utilities from scratch. Installed Anti-Virus and then removed it. Tried to upgrade to Windows 10. It turned out that the total progress bar got stuck at 32%, and down below it says something like installing features and drivers 6%. It just stopped there, not moving forward. (This happened before I uninstalled the AV) Do you guys have any idea? Upgrading to Windows 10 really drives me crazy:(

I assembled parts of different makers to make this PC.  <-- It may not be capable of running Windows 10.

why not post the specs of the parts?  then we can assist better

@nobus, I ran memtest86+ and passed with no error. So I detached three of the four RAMs only leaving 8GB RAM and I made it connected to only one system hard disk, and I am trying again.

CPU: i7 4770K
RAM: ADATA 8GB DDR3 2133 * 4
SSD: Samsung 850 EVO 250G
MB: MSI Z87-GD65 Gaming

And it was rolled back to Windows again. I really has no idea...

Although my problem was not solved yet, I still like nobus's comments. And I am merging this with another thread.

ah - an SSD - but i checked - no firmware updates for it
you disconnected all other hardware also ?
otherwise, i'm starting to believe in a mobo problem
