Well, your 3AM guess was right on and set me on the correct path. I have the gigabyte drivers with V-Tune 2 program to adjust the vid cards clock sppeds. The default core speed was 393 and default memory speed was 596. I underclocked both (to 359 and 554, the lowest values I could) and the problems all disappeared. No more artifacts and Civilization IV runs without crashing. Just to check, I overclocked both values by 25 points and the artifacting became much worse and Civ IV crashed just after boot.
So, is this and indication of the impending demise of my vid card, or just signs of old age (the card, not mine)? The cooling unit on the card is a bit anemic, but seems to be functioning. I removed a small amount of dust, but no caking or fan stopping amounts. So, should I trust to good karma, or begin shopping for a new vid card? Thanks for your help.
