Before we can even begin to find the underlying cause (and it may be the problem in itself) you need to update your asacpi.sys. Yours is from 2005


The pre 2009 version of this driver is a known BSOD cause.

Scroll down to the utilities category, then scroll down to the "atk0110 driver for windowsxp/vista/windows 7 32&64-bit" (it's about the 12th item down).

Download and install it.

Go to c:\windows\system32\drivers to check and make sure that the asacpi.sys file is date stamped from 2009 or 2010 (not before).
