Hello Redwine
I have the same card as you and never experienced this kind of problem.
I dont think this is a matter of wrong drivers.
Im not so sure that 70 degrees is to hot either. This is a powerful card and it easily get warm. I'll check out my temperature during gameplay and will come back with the temperature I have.
The other thing is if you have
attached the card properly in the socket on your mother board? Even the slightest misconnection can cause strange glitches. Try to make sure it's proper mounted in the socket of your motherboard. Is this an PCI express card?
Then if heat is the problem, make sure there is a empty room next to your grafic card. Will be better for cooloing your card.
I'll return with temperaturetest
