I've taken a look at the crash dumps, and it appears that the crash is coming from drivers for an ATI based graphics card.. however, you appear to have a Nvidia GPU as your primary adapter. Do you happen to have an ATI card installed alongside your Nvidia card?
If you don't it would be best to remove the faulty amd / ati drivers from the system. Alternatively, if you do have a card from that manufacturer in there, please update the drivers to the latest version and test again.
