These 4 were related to your atheros driver. I would re-install newest driver available.

How To Find Drivers:
- search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program
The most common drivers are listed on this page: Driver Reference
