If you keep starting new threads for the same problem you're going to rapidly make yourself unpopular around here. (This is the 3rd seperate one related to your video card problems.) The people most likely to help you read all of the traffic here (generally using the "View posts since last visit" search) and posting the same thing multiple times under different subject areas is just going to annoy them. Unless Cecil tells you you're off topic in a forum (He didn't because Hardware was a good place to post your original) you should follow up to the orginal thread.
