Re: Unexpected BSOD results in Crush Dump
Start by updating a couple drivers
gdrv.sys 3/12/2009 Gigabyte Tools, possibly EasyTune, update, or uninstall
PxHlpa64.sys 6/23/2009 Px Engine Device Driver Sonic Solutions Software, update or uninstall
GEARAspiWDM.sys 5/18/2009 update from here Driver updates - GEAR Software
RTKVHD64.sys 8/18/2009 unpdate from here Realtek
Rt64win7.sys 7/30/2009 update likely from here Realtek make sure your card is in the list, if not use the navigation menu in left column of site to locate your specific card.
All four of your dump files are virtually identical

CRITICAL_OBJECT_TERMINATION (f4)

My concern is a potential infection, because your two most recent dump files are showing an apparent random Temp file loading as a driver
005ECED.tmp
and
0053294.tmp
So I would suggest employing most if not all of the following resources to make sure there is no malicious software present on your machine.
