It looks like your system hasn't been updated since 2010.
You're way behind on Windows updates. The dumps indicate a video driver
fault (nvlddmkm.sys) and a desktop window fault (dwm.exe). Both most likely due to old drivers
and lack of updates.
Turn on the Windows update service and check your PC's mfg website for driver updates.
Hmmmmm. That's interesting. Just noticed your specs say ATI Radeon but you're running Nvidia drivers.
Whut up wit dat?
