Welcome to SF

There are no dump files in the attachment. Please configure for small memory dumps as explained here:

• Dump Files - Configure Windows to Create on BSOD

Netio.sys is a network error which is often caused by stubborn antivirus apps like Norton.

As a test, I would recommend uninstalling Norton and using Microsoft security essentials.

Norton tends to cause BSOD-s and several other issues. I would recommend 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.
    • How to Scan Your Computer With Multiple Antivirus Programs - How-To Geek
    
    
  
  

   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.

System Optimisers

Please remove the following software:

Code:

Advanced SystemCare 6	"c:\program files (x86)\iobit\advanced systemcare 6\asctray.exe" /autostart	NT AUTHORITY\SYSTEM	HKU\S-1-5-18\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Advanced SystemCare 6	"c:\program files (x86)\iobit\advanced systemcare 6\asctray.exe" /autostart	SamuelSung\Champster	HKU\S-1-5-21-3697776081-4079981704-496958710-1001\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Advanced SystemCare 6	"c:\program files (x86)\iobit\advanced systemcare 6\asctray.exe" /autostart	.DEFAULT	HKU\.DEFAULT\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

This software is a known cause of BSOD's. The windows 7 operating system does not require these registry cleaning software. They often tune-down rather than tune-up and can wreck the OS beyond repair. Microsoft have improved Windows 7 significantly and it is much better at organising and optimising itself than its predecessors. Check this, this and this thread for evidence.

If you feel the need to use a registry cleaning or optimisation software, most of us recommend the use of CCleaner - PC Optimization and Cleaning - Free Download but make sure you back up the registry before making letting ccleaner delete anything.

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

• SFC /SCANNOW Command - System File Checker

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

• Disk Check

Reduce items at start-up. Nothing except anti-virus is required plus improves the time for logging in windows.

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

Let us know the results.
