GPU H/W failure. This one is an easy one to diagnose:
Bug Check 0x116: VIDEO_TDR_ERROR
This indicates that an attempt to reset the display driver and recover from a timeout failed.
What is happening is the display driver is crashing, Windows is commanding the driver to reset, and the driver crashes when its attempting to reset.
This typically means either a bad driver version, or the GPU is failing. So try a different WHQL driver, and if the problem remains, RMA the GPU.
