You are aware that these dump files are ~2 to 3 months old, correct? Anyway, we have various different bug checks from the attached DMP files:


This bug check indicates that the Intel CPU generated a trap and the kernel failed to catch this trap.

If we take a look at the call stack (warning, it's quite large):

We can see many tcpip.sys and a few NETIO,.sys calls. These are Microsoft network related calls and routines. We then reach a DirectX Kernel call into a few igdkmd32.sys calls which is the Intel Graphics driver.

With this said, we likely have a 3rd party source (antivirus, firewall, some 3rd party network app) causing NETBIOS conflicts, and a need to update the video card drivers.


On one of the many *7F's we have, there are a ton of cfosspeed6.sys calls which is the
cFosSpeed - The Internet Accelerator driver.

We also have a REFERENCE_BY_POINTER (18) bug check.

This indicates that the reference count of an object is illegal for the current state of the object.

If we take a look at the call stack:

1. Uninstall cFosSpeed - The Internet Accelerator.

2. Remove and replace BitDefender with Windows 8's built-in Windows Defender:

BitDefender removal -

3. Ensure you have the latest video card drivers. If you are already on the latest video card drivers, uninstall and install a version or a few versions behind the latest to ensure it's not a latest driver only issue. If you have already experimented with the latest video card driver and many previous versions, please give the beta driver for your card a try.

4. Just a side question, I see you have TuneUpUtilities installed. What are you using it for?
