Pytanie Raymarch test hard reboots my PC..

New issue, Seems you have fixed the black screens with latest nvidia drivers. Now the final test (Raymarch test) Hard Resets my PC, makes it reboot half way through the test... Please sort it out!

i7 4770k, EVGA 780 ti classified, 16 gb hyper x 1866mhz. win 7 x64.

Please check the temperature of your GPU. I believe that it may be overwarming.

There isn't a chance the GPU is overheating. Its a new EVGA 780 ti and the temps never go above 72c as seen in GPU-z and HWmonitor. I can run all other tests just fine. 3dmark, firestrike extreme, unigine, valley.
