BLUE SCREEN(VideoCrash) Related

I have recently been experiencing a blue screen.So i removed my Nvidia GeForce 6800 card from the motherboard and booted back up. Got the same screen.So then i restarted the system and went into bios setting's thinking maybe the bios was confused where the card had been there before and the Nvida drivers were still on my hard drive. So i set it to on-board video as my video setting''s.Well it worked for a day maybe not even a full day and the same screen popped back up.So i reinstalled my on-board video driver's. Still the same thing. But whats weird is sometimes it boots up fine and the majority of the time it does not. Just blue screen.I ran the GeForce 6800 in my system since i built it back in late 09.I don't understand why all of a sudden this problem has arisen.I called windows of course they were no help at all. In fact i knew more about the problem than they did and they couldn't give me any explanation.If anyone find's a fix or anymore information about this.Please let me know because I'm afraid if the problem persists ill have no choice but to reformat.I cant believe that it has not hit me with the blue screen yet.

There is another poster with same problem,but never any more info. Link Below.
