Hi,


All 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

athuw8.sys is the Qualcomm Atheros UB91/UB93/UB94 Network Adapter, (USB wireless adapter) driver.

This driver may not be compatible with Windows 8, so please see if there's an update ASAP. If not, uninstall the software + remove the adapter for troubleshooting purposes.
