I have been getting crashes in the last month after the first program opens following startup. The error is most often PAGE_FAULT_IN_NONPAGED_AREA and sometimes MEMORY_MANAGEMENT. The issue usually does not happen twice in a row. That is, when the computer restarts after crashing, it normally runs smoothly until I shut it down again.
Running memtest for several hours came up clean. chkdsk did not appear to solve anything or reveal any problems. Windows is up to date.

Driver Verifier-- tracking down a mis-behaving driver. Created by ZigZag3143, Co.authored by by JMH3143
In Autoruns right click on PxHlpa64.sys and select Search Online. Does that offer any further clues?
Here is what you should do. Look in control panel (CP) to see if any of the programs listed in the link below, appear as an entry in CP.
http://www.carrona.org/pxhelp20.html
If you can't find any of them, that means that the program related to, or associated with PxHlpa64.sys may have already been uninstalled, leaving behind, just the driver and possibly registry entries.
Download "autoruns" and use it to locate and disable the driver, after making certain that all Microsoft entries have been hidden, to eliminate the possibility of a mistake.(instructions in the youtube video link below.)
Thank you.
The only program that looks remotely familiar on that list is Adobe Photoshop, but I don't have Lightroom installed.
It's far more likely that I uninstalled a program that used the driver.
PxHlpa64.sys has been disabled via Autoruns.
Should I wait to see if I continue to crash or should I rerun driver verifier?
Which software in the list in the link do you have?
I have Adobe CS6 installed, but I didn't think that came with Lightroom. No other programs look familiar or can be found in my Add/Remove programs list.
I am willing to uninstall CS6.

Autoruns for Windows v12.03
This utility, which has the most comprehensive knowledge of auto-starting locations of any startup monitor, shows you what programs are configured to run during system bootup or login, and shows you the entries in the order Windows processes them. These programs include ones in your startup folder, Run, RunOnce, and other Registry keys. You can configure Autoruns to show other locations, including Explorer shell extensions, toolbars, browser helper objects, Winlogon notifications, auto-start services, and much more. Autoruns goes way beyond the MSConfig utility bundled with Windows Me and XP.
Autoruns' Hide Signed Microsoft Entries option helps you to zoom in on third-party auto-starting images that have been added to your system and it has support for looking at the auto-starting images configured for other accounts configured on a system
