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.

This custom built machine is approx 1.5 years old, problems began 1 month ago.
EDIT: Crashes just started during "normal" operation instead of simply on startup.

Please run driver verifier (DV) per the instructions in the link below.
Note: Make sure to read and remember the steps to reset DV in the event of a crash, and post a link to the newly generated crash dump here.
Driver Verifier-- tracking down a mis-behaving driver. Created by ZigZag3143, Co.authored by by JMH3143
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.

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?
Yes, wait. I would think that, it would be the next logical step.
Just experienced a Memory Management BSOD after startup with PxHlpa64.sys disabled.
Dump File:
Sidenote, is there any software available to me that would allow me to analyze dump files myself?
In Autoruns right click on PxHlpa64.sys and select Search Online. Does that offer any further clues?
I saw a couple forum posts where people used Autoruns to disable the driver, but that's about it.
Crashes are continuing, I just got a Memory Management one.
Here's the dump:
Select Start, All Programs, Accessories, right click Command Prompt, and click Run as administrator from the drop down menu.. Type *cd* and press ENTER. Type "chkdsk c: /r" without the quotes and hit ENTER. Make sure you include the spaces indicated. Enter Y when asked whether you wish to run chkdsk on restarting the computer. Type exit, press the ENTER key and restart the computer.
Please run System File Checker and say if it cannot fix corrupted files: http://support.microsoft.com/kb/929833
Please run Driver Verifier and provide further dump files as they arise.
Please restart your computer, allow 30 minutes for the system to run before uploading further information so that the impact of making changes can become apparent.
Please provide an updated copy of your System Information file. Type System Information in the Search Box above the start Button and press the ENTER key (alternative is Select Start, All Programs, Accessories, System Tools, System Information). Select File, Export and give the file a name noting where it is located. Do not place the cursor within the body of the report before exporting the file. The system creates a new System Information file each time system information is accessed. You need to allow a minute or two for the file to be fully populated before exporting a copy. Please upload the file to your OneDrive, share with everyone and post a link here. Reports in normal mode preferred. Please say if the report has been obtained in safe mode.
Please upload and share with everyone fresh copies of your System and Application logs from your Event Viewer to your One Drive (formerly Sky Drive) and post a link here. You can remove the earlier copies of the logs from your OneDrive.
To access the System log select Start, Control Panel, Administrative Tools, Event Viewer, from the list in the left side of the window expand Windows Logs and select System. Place the cursor on System, select Action from the Menu and Save All Events as (the default evtx file type) and give the file a name. Do the same for the Applications log. Do not provide filtered files. Do not place the cursor in the list of reports before selecting Action from the menu. Do not clear logs whilst you have a continuing problem.
