Arbitrary BSOD - Page Fault In Nonpaged Area

I'm running a relatively fresh install of Windows 7 Ultimate x64, and have had three BSOD since the install. It tends to happen while either web browsing or navigating through my file directories in Windows itself - fairly benign behavior.

I have followed the instructions on this site, and am attaching a .zip of my processed dump files, as well as an .html file of my Health Report.

This is a 64-bit machine.
It was custom-built, and I believe the Windows 7 install is purchased from a retailer.
Hardware is about a year old.
Windows was installed about 6 days ago.
I have thoroughly run MemTest, with no errors at all.

(Note that this is not my computer, but a client's. I'm a bit stumped, and any insight is appreciated.)

Problem Devices:

Code:

Universal Serial Bus (USB) Controller	PCI\VEN_1033&DEV_0194&SUBSYS_84131043&REV_03\4&CF85AA7&0&0010	The drivers for this device are not installed.
Not Available	ACPI\ATK0110\1010110	The drivers for this device are not installed.

The above should be installed from the motherboard support site. The first one is under USB, and second is in utilities.


Security Software: ??? Make sure to install security software. I recommend either of these:

• Microsoft Security Essentials - Free Antivirus for Windows coupled with Malwarebytes. Do not start the free trial of Malwarebytes. Just use the standalone version, update it, and scan your computer once a week with Malwarebytes and with Microsoft Security Essentials.
  
  
• Good and Free system security combination.

After installing your security software, update it, and then run full scans today with each program. Report back the results of the scans.


Please remove Daemon Tools, as it uses a driver called dtsoftbus01.sys that is known to cause BSODs with Verifier enabled, and it prevents determining driver problems using Verifier.

I prefer TotalMounter as my CD/DVD virtualization software as it allows me to burn images to a virtual CD/DVD if I just want an ISO file instead of a disc, and it is free.

Many use MagicISO - Convert BIN to ISO, Create, Edit, Burn, Extract ISO file, ISO/BIN converter/extractor/editor as well, which is also free.


Crashes are pointing to memory problems or driver conflicts.

• If you are overclocking any hardware, please stop.
  
  
• Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).
  
     Warning

  Before you proceed with the following, answer these two questions: Are you still under warranty? Does your warranty allow you to open up the machine to check hardware? If you are unsure of the answers to these questions, contact your system manufacturer. WARNING: The steps that follow can void your warranty!!!
  
  For Part 3: If You Have Errors: If you swap any memory components, follow these steps for ESD safety:
  
  1. Shut down and turn off your computer.
  2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
  3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
  4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.
  
  Once these steps have been followed, it is safe to remove and replace components within your computer.
  
  
• An underlying driver may be incompatible\conflicting with your system. Run Driver Verifier to find any issues. To run Driver Verifier, do the following:
  
  a. Backup your system and user files
  b. Create a system restore point
  c. If you do not have a Windows 7 DVD, Create a system repair disc
  d. In Windows 7:

  • Click the Start Menu
  • Type verifier in Search programs and files (do not hit enter)
  • Right click verifier and click Run as administrator
  • Put a tick in Create custom settings (for code developers) and click next
  • Put a tick in Select individual settings from a full list and click next
  • Set up the individual settings as in the image and click next
    Attachment 215832
  • Put a tick in Select driver names from a list
  • Put a tick next to all non-Microsoft drivers.
  • Click Finish.
  • Restart your computer.

  
  
  If Windows cannot start in normal mode with driver verifier running, start in safe mode. If it cannot start in safe mode or normal mode, restore the system restore point using System Restore OPTION TWO.
  
  If you are unable to start Windows with all drivers being verified or if the blue screen crashes fail to create .dmp files, run them in groups of 5 or 10 until you find a group that causes blue screen crashes and stores the blue screen .dmp files.
  The idea with Verifier is to cause the system to crash, so do the things you normally do that cause crashes. After you have a few crashes, upload the crash reports for us to take a look and try to find patterns.
  
  When you are ready to disable Verifier: Start Menu -> All Programs -> Accessories -> Right click Command Prompt -> Run as administrator -> Type the following command and then Enter:
  verifier /reset
  -> Restart your computer.
