Hi,

Both of the attached DMP files are of the DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1) bug check.

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.

By default, the fault is NETIO.sys which is the Network I/O Subsystem (not the true cause). I've seen tons and tons of these *D1 network related crashes lately, and almost all of them are after upgrades to Windows 8 and or 8.1. We generally have two main causes:

1. Network drivers themselves need to be updated.

2. 3rd party antivirus or firewall software that carried over from the upgrade and or install is no longer compatible and is in general causing NETBIOS conflicts and corruption.

I see McAfee after taking a look at your loaded modules list, so let's go ahead and remove and replace McAfee with Windows 8's built-in Windows Defender for temporary troubleshooting purposes:
