BSOD driver_irql_not_less_or_equal

Welcome

Your crashes seem to be network related.

Norton often contributes in such crashes, I'd consider uninstalling it with the Norton Removal Tool and replace with Microsoft Security Essentials TO TEST.

• Norton Removal Tool

Microsoft Security Essentials.

Recommended from a strict BSOD perspective, compatibility & stability compared to other antiviruses/internet security software. It is free and lightweight:-

• Microsoft Security Essentials - Free Antivirus for Windows
  
  • Malwarebytes : Malwarebytes Anti-Malware removes malware including viruses, spyware, worms and trojans, plus it protects your computer
    
    • Good and Free system security combination.

   Warning

Do not start the free trial of Malware Bytes; remember to deselect that option when prompted.

Run a full scan with both (separately) once downloaded, installed and updated.
Make scans with the following:

-Kaspersky TDSSKiller

• Anti-rootkit utility TDSSKiller

-ESET online scanner

• Free Online Virus Scanner | ESET

Perform a System File Check:

1. Click on the start
2. Type CMD on Search
3. Left click and Run as Administrator
4. Type SFC /scannow

Full tutorial here:

• SFC /SCANNOW Command - System File Checker

Disk Check on your hard drive for file system errors and bad sectors on it:

The Assumptions You Make About Your Slow PC (and Why They're Probably Wrong)
Reduce items at start-up. Nothing except anti-virus is required:

• Startup Programs - Change
• Troubleshoot Application Conflicts by Performing a Clean Startup

Update the following drivers:

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If kernel debugger is available get stack backtrace.
Arguments:
Arg1: fffffa800a11ce48, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, value 0 = read operation, 1 = write operation
Arg4: fffff88006013a60, address which referenced memory
