rt86win7.sys is blamed, and it's your RealTek networking driver.
It's most likely the driver that's at fault, but it could also be an issue with the card itself.
I would first try downloading the most current Windows 7 driver from the Realtek website: Realtek
Then uninstall the currently installed network drivers,
Then install the one you downloaded
Code:
BugCheck A, {13, 2, 1, 8404d0ac}

Probably caused by : Rt86win7.sys ( Rt86win7+c209 )
