I only ran the last 9 memory dumps - there was a large gap in time between them and the earlier dump files, so I suspect that the earlier one's were fixed.

They all blame KeyMagic.sys - a component of the Apple USB wireless keyboard
Please do the following to remedy it:
- Download the latest drivers for this device (and Win7) from the Apple website (if there are no Win7 drivers, please post back)
- Uninstall the drivers/software for this device from your system
- Install the freshly downloaded drivers
- Monitor for further BSOD's

Also, Please update or remove these older drivers that were loaded at the time of the crash. Don't use Windows Update or the Update drivers function of Device Manager. Please use the following instructions to locate the most current drivers:

How To Find Updated 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 for Win7 (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.
