Security App
Crashes indicate AVG and McAfee being a possible cause. Remove them and replace with Microsoft Security Essentials to see if it provides more stability. Uninstallers (removal tools) for common antivirus software. Plus you shouldn't be using two antivirus software on your system. They sure can cause things like BSOD's. Q: Is it bad to run multiple antivirus programs?

Microsoft Security Essentials and Malwarebytes, both recommended from a strict BSOD perspective.

Microsoft Security Essentials, Free antivirus for windows

Malwarebytes Anti-Malware Free

   Information

DO NOT start the free trial of MalwareBytes. Deselect the option when prompted.

   Tip

Make full scans with both separately.

Start up
Keep less stuff at the start-up. Only anti-virus, this helps avoid driver conflicts and improves time to log in to windows.

Hope this helps for now, good luck.

Any update?

Are you sure you have followed all the steps and made all the changes mentioned on my other post?

I can still see McAfee on your system.

Is the laptop still under warranty?

I get that but why not McAfee? If it wasn't creating a problem you could install it back later on. :)
