2x7970 freeze windows and linux too

[hoze]

Then this might be a heat problem. Try running both cards with an open case and maybe put another fan there.

It's allready a open case . I can touch the card with my hand, and it's not that hot!

It's strange that freeze after 3-5sec. I think the card can't get that high tempeture in 3-5 sec.... These cards with 3 cooler on
each...no way to get overheat in that short time...
