BSOD Netio.sys, tcpipreg.sys

What happens if you turn off your network adapters? Can you shut down?

Also, see if you can Troubleshoot Application Conflicts by Performing a Clean Startup and determine if it is an application causing the conflict.

Actually what happens is this. If I try to shut down Windows 7, I get to the shutting down screen and then I get the bsod. Disabling network adapters didn't help, same result.

What antivirus originally came with the system, and how did you remove it?

Mcafee SecurityCenter and I removed it from program and features. Then I ran their uninstaller to clean up any remnants.

Alright, that rules that out. It is possible you have corrupted network adapter drivers. Download all the latest network adapter drivers for your system from Drivers and Downloads | Dell [United States]. Restart the computer using the Advanced Boot Options to get into Safe Mode and uninstall all network adapters as follows.

1. Click Start Menu
2. Right Click My Computer/Computer
3. Click Manage
4. Click Device Manager from the list on the left
5. Expand Network Adapters
6. For all adapters:
   
   • Right click the device
   • Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
   • Put a tick in Delete driver software for this device (if this option is available, otherwise just hit OK) and hit OK
7. Install the latest drivers for each device.

Alternatively:

1. Login as an adminstrative user.
2. Click Start Menu
3. Click Control Panel
4. Click Hardware and Sound
5. Click Device Manager (the last link under Devices and Printers)
6. Expand Network Adapters
7. For all adapters:
   
   • Right click the device
   • Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
   • Put a tick in Delete driver software for this device (if this option is available, otherwise just hit OK) and hit OK
8. Install the latest drivers for each device.

Already I give this a try.

Do the following to check for corrupted files on your system. I realize the system has been reset to the factory image, but it is a good idea to make sure, anyway.

• Run Disk Check with both boxes checked for all HDDs and with Automatically fix file system errors checked for all SSDs. Post back your logs for the checks after finding them using Check Disk (chkdsk) - Read Event Viewer Log
  
  
  
• Run SFC /SCANNOW Command - System File Checker up to three times to fix all errors. Post back if it continues to show errors after a fourth run or if the first run comes back with no integrity violations.

I also still think it is worth trying to Troubleshoot Application Conflicts by Performing a Clean Startup to see if it is an application conflict.

Already tried a clean startup earlier.. Working on the other things currently.

Alright, good to know. When you reverted to the factory image, did you have any trouble shutting down from the get go, or did it develop after installing updates/programs/drivers/etc.?

No problem shutting down when I restored the factory image initially. SFC didn't find any integrity violations.
