All good ideas, but I'd start with the vid card and then continue. Your not getting any video, so I ASSUME not even the bios info screen. So then there is no video source. So I would assume that the video card is at fault. It's the easiest route. Then continue one at a time on each, you can remove the vid card and see if you at LEAST get a post error. Aside from that, leave IN the vid card or you wont ever post, just get a dbl beep error (on rare occasions different beep code but almost every system I've worked on it's like the 2 beep code is universal or something for no video). If its installed you may not get a post error because the bios sees it, but there is not a proper connection.
If you argue with an idiot he will drag you down to his level and beat you with experience.
