BSOD when computer is idle

Received a BSOD while away from the computer.
Dell Bluescreen Troubleshooter resulted in the following:
The "Unknown" driver (C:\Windows\system32\drivers\teedriverx64.sys) appears to have caused the system crash.

I looked up the teedriverx64.sys and it is the Intel Management Engine Interface driver but the driver is up to date.

I ran BlueScreenView and the results are that the Wdf01000.sys is part to blame.

I ran Malwarebytes but the system came up clean.
Installed all windows updates
Installed all driver updates - with the exception of the Intel 6235 update which doesn't actually update. I'll call Dell on that one.

Full system diagnostics came back clean.

I'm not confident that the Windows updates will resolve the issue. Attached is the SF Debug Tool and BlueScreenView results. Can someone please review it and let me know if there is anything else I should be looking at?

Dell E6540, Win7 Pro, i7vPro, 8gb RAM...

Thank you in advance!

Hi danhinze.

Code:

fffff880`0bcf9150  fffff880`05371500Unable to load image \??\C:\ProgramData\Symantec\Symantec Endpoint Protection\12.1.3001.165.105\Data\Definitions\BASHDefs\20140121.011\BHDrvx64.sys, Win32 error 0n2

So, uninstall Norton and all Symentec products using Norton Removal tool. At least as a test. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Download, install and update those, and then run full system scans with both of them, one by one; for a safety reason, as the installed antivirus is failing.

Also, some issues are causing by Intel Management Engine.

Code:

Probably caused by : TeeDriverx64.sys ( TeeDriverx64+e4fa )

Intel Management Engine is not anything must to have. Better you uninstall it.

Also, test your RAM modules for possible errors; keeping the versatility of the issue in mind.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.
If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

Let us know the results.
