Memory Corruption

This malfunctioning driver is a windows defender driver.
Typically windows drivers are fixed by windows updates.
There are no other 3rd party drivers found that were malfunctioning in the windows debugging.
The event files and the windows error reporting indicated that in the month of September you were having problems with the Nvidia graphics card drivers.

Drivers can malfunction like software.
Sometimes drivers must be updated, reinstalled, or rolled back.
I think the re-installation of the Nvidia driver followed by the major October Windows upgrade should fix the infrequent computer bsod.

The event files had indicated:

Code:

An error was detected on device \Device\Harddisk3\DR7 during a paging operation.

Code:

An error was detected on device \Device\Harddisk3\DR6 during a paging operation.

Code:

The IO operation at logical block address 0x2300 for Disk 2 (PDO name: \Device\00000075) was retried.

Code:

An error was detected on device \Device\Harddisk2\DR3 during a paging operation.

Code:

The IO operation at logical block address 0x1c6c00 for Disk 2 (PDO name: \Device\00000078) was retried.

Code:

{Delayed Write Failed} Windows was unable to save all the data for the file \Device\HarddiskVolume10; the data has been lost. This error may be caused if the device has been removed or the media is write-protected.

Code:

Disk 3 has the same disk identifiers as one or more disks connected to the system. Go to Microsoft's support website (http://support.microsoft.com) and search for KB2983588 to resolve the issue.

So all of the drives are being troubleshooted.
So far you found errors in the bitmap on one drive that was fixed.

If you're looking for things to rule out or rule in. I made some changes to my hard drives recently. Around the middle of September we discovered that the hard drive we have in our hard drive bay was failing. This would have been sometime after the BSOD on September 10th. We removed that drive and ordered 2 WD Blue 4TB drives. Those were added to our drive bay on September 18th or 19th. We had an online backup of the failed drive, and we received and loaded those files back on to the new drives starting on September 28th. All the files finished loading on the 29th.

So, the old drive could have been related to the first 3 crashes, but it wouldn't have been related to the last one. Also, the 2 new drives couldn't have affected the first 3, but might have impacted the last one. I'm not sure if the dumps look to be all the same thing, or if there are indications that it is different problems. But if they are all the same, then it wouldn't have been the old drive, or the two new drives, causing it.

Edit: I just saw your post. Those events are likely related to the failed drive I replaced.

The plan currently is to:
1) evaluate all drives with
a) chkdsk /x /f /r
b) HD Tune with health, error scanning, and benchmark
c) Sea Tools for Windows: SMART, short, and long generic

2) Update/uninstall/re-install the Nvidia graphics driver
3) Wait for the major windows upgrade in the middle of October
4) evaluate any new bsod if there are any
5) with you being comfortable using windows driver verifier it can be restarted at any time to troubleshoot the drivers.

Here are the hdtune results of my other internal drive. Note that this is a 3TB drive, but hdtune only says it is 2199G. I'm going to reinstall nvidia, then I'll run the chkdsk on it.

Here is the chkdsk result for the same hard drive as the hdtune pictures above:

I got the nvidia drivers reinstalled (after completely removing them). I also applied the windows update from last month.

I just finished scanning my first external drive. hdtune doesn't show any health information for it. Also, after running chkdsk I didn't see anything logged in the windows events for it. But I did grab a screen shot.
