I've had what seems to be incredibly bad luck with graphics cards in recent years. Card after card would seemingly degrade, beginning with minor artifacts in games which would be fixed temporarily by driver updates or maybe game reinstalls, until symptoms began to show up in the normal desktop environment and even the POST. After the last card went funny I borrowed an old card of a friend (an ATI x1800. All the other cards were nvidia around 7900s) which, until now, and for a long time has been perfectly fine. Now the game artifacts have shown up again and odd lines during POST, too. So now i'm thinking is there another component, maybe the mobo, which is somehow damaging the cards? Could it be a voltage issue? Thanks in advance, if anyone can shed any light!
