the bugcheck indicates that the system could not read the hard drive for some reason.
(check SATA connections, update chipset drivers, enable hotswap for the port the drive is on, maybe delete the pagefile and recreate it (if there is a bad sector where your page file is located)
-other issues from debugger:
you have window 7 RTM, you will need to apply service pack and updates (your graphics drivers will hit bugs that were fixed years ago in the updates)
- you have 2 copies of this driver installed (I would remove both)

also, just not a good sign to see drivers loaded from a temp directory:

I would remove this software.
