Cryis warhead. Double Grr!

Having had my previous thread closed, I am posting the same one again, as I am still looking for an answr. by way of explanation, I should have said that the game is LEGALLY downloaded through my Steam acount.. I prepaid before it came out, and waited for the release date.


Crysis warhead is having a few probs with me. I have all settings on high, res is 1920 x 1080. Works beautifully, but I get lock ups randomly- if I close and restart, I can get past the point, but chances are it will ock up a while later. Crysis(original) runs fine, so I am inclined to think its not a hardware issue re heat etc. I had to re download the game after I rebuilt my rig, along with windows, so I am on a nice fresh install. Any ideas?
