oclHashcat problem with overheat probably

[Vidramon]

You show the GPU temp while rendering and everything is fine. Can you start hashcat and monitor the temps again? How much higher are they? If it the screen goes corrupt after 30 sec. just stop hashcat after 29

How I can stop it, when I can't see anything except white-gray lines over all screen, I have no idea what is happening in background ?

I said that lines goes on screen about 30 second from start, not 30 exactly, so I do not know in which time exactly will come.

I will star one more time to see what is happening, and if goes like fist time ( white - gray lines ), I will stut down my computer from electrical energy.
