BSOD Bugcheck error 0x0000000a event id 1001 help.

Thanks for the dumps!

We have various bug checks:

IRQL_NOT_LESS_OR_EQUAL (a)

This indicates that Microsoft Windows or a kernel-mode driver accessed paged memory at DISPATCH_LEVEL or above.

This bug check is issued if paged memory (or invalid memory) is accessed when the IRQL is too high. The error that generates this bug check usually occurs after the installation of a faulty device driver, system service, or BIOS.

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)

This indicates that a kernel-mode driver attempted to access pageable memory at a process IRQL that was too high.

A driver tried to access an address that is pageable (or that is completely invalid) while the IRQL was too high. This bug check is usually caused by drivers that have used improper addresses.

If we take a look at the call stack:

KMODE_EXCEPTION_NOT_HANDLED (1e)

This indicates that a kernel-mode program generated an exception which the error handler did not catch.

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e)

This indicates that a system thread generated an exception which the error handler did not catch.

^^ The 1st parameter of the bug check is 0xc0000005 which indicates an access violation occurred:

2: kd> .exr 0xfffff8800333f3b8
ExceptionAddress: fffff88004a9fd8d (athrx+0x0000000000250d8d)

^^ The violation occurred in athrx.sys which is the Atheros network adapter driver.

---------------------

1. Remove and replace AVG with Microsoft Security Essentials for temporary troubleshooting purposes as it's likely causing NETBIOS conflicts:

AVG removal - http://www.avg.com/us-en/utilities

MSE -  http://windows.microsoft.com/en-us/windows/security-essentials-download

2. 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.

3. Ensure your network drivers (specifically Atheros) are up to date via Gigabyte's website.
