Windows 7: Video Card causing BSOD

I'm running WIndows 7 64, at first I had a Geforce 8800 GTS, which worked fine for 3 years, but after moving I started getting red speckles and blank outs and eventually every time I tried logging in I would get a BSOD causes by nvlddmkm.sys. People said my card was dying, so I replaced it with an Asus ENGTX460. That was working fine for a coouple hours, but then that started causing BSOD. After wiping and reinstalling the drivers some more, I can log into Windows, but now the device manager says "windows has stopped this device because its has reported problems" and many applications can't detect the video card. Also the screen is now covered in yellow lines and i really hope this card isn't meeting the same fate as my last one in less than a day.

As the sticky suggested I have collected those dump files into this zip
