This can be caused by a bad driver or buggy software.


A kernel-mode process or driver incorrectly attempted to perform memory operations. Typically, a faulty driver or buggy software causes this.

I know it's either faulty driver or software.  How do I narrow it down?  This is a brand new Dell OptiPlex Gx 620.  
10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

Brand new system! return to Dell, though.
When does the BSOD occur? While booting or while running? If while booting, you could start the system and press F8 to get your boot menu. One of the menu options should be to log the boot process. It then lists all the loaded drivers until the system crashes. That should give you an idea.

If it happens while the system is running, try to find out if it crashes when you are doing something specific, this should also give you an idea of the reason. If there is any easily removable hardware, remove that to eliminate any addon hardware from the equation.

It always happens when the user is logging on to the computer.  
That could still belong to the booting process, so check the option with the boot log. Also try not having the NIC connected.
If you haven't installed new hardware or software preceding the BSOD, you may have a bad memory stick. If Dell doesn't provide a memory test app try MemTest86:
Some version of the following software may cause bugcheck code C2. If you can provide the minidump, I can find out the culprit.

klpid (Anti-hacker)
tm_cfw.sys (Trend Macro)
ThinkVantage Resuce & Recovery

Bugcheck may also caused by faulty ram or bad paging space. You had better run chkdsk /r and re-allocate the paging space. Run memtest to stress test the ram.

I spoke with a Dell Tech. and ran the Crash Test Tool.
The faulty program appeared to be NavEx15.sys.  
I reinstalled the NIC driver and reinstalled Symantec Antivirus and haven't crashed yet.  We'll see what happens now.  
Get Avast! Antivirus personal, free for home use, doesn't use as many resources as Norton by a long way, and in my point of view is much more stable and detects more malware. With symantec products you tend to get all kinds of problems.
If you provide the minidump, I will find out the culprit. Re-post if you still have o/s issues.

The last minidump is already posted.  I haven't had another blue screen after the reinstallation of the NIC driver and SAV.  
You posted the output of dumpchk which is insufficient to find out the root cause. The output of windbg has much diagnostic information.
