nvlddmkm and crashes

about a month ago, my computer started crashing with a blue screen after 2+ hours of playing 3d games. it has gotten more and more frequent and sometimes it crashes randomly while idle. before it bluescreens my main screen goes black and the image on the second screen gets scrambled. i am fairly sure it is a bad video card because i tried reinstalling all drivers and even reinstalled windows. none of my parts are overclocked.

My Specs:
Windows 7 Home 64-bit
samsung 4gb ddr2-1200
corsair 550w psu
samsung 500gb 5200rpm 32mb buffer hdd
EVGA factory overclocked 1gb GTS250(i have tried underclocking)
EVGA 780i SLI mobo
intel q8200 2.33Ghz quad core
Massive titan fenrir heatsink
hauppage tv tuner
thermaltake m9 case with plenty of fans and ventilation

my minidump files are attached

Well it still is pointing to the directx component of your video driver. I could be heat, or a PSU issue, but I suspect it is the driver.

You need to remove all the remnants of the current driver and then install a fresh copy.

You could also run a system file check just to be sure.
sfc /scannow

let us know if we can help

i am going to reinstall the drivers as u said but i cant see how that is the problem because i reinstalled windows and still had the same problem

i reinstalled the drivers and restarted and used drivercleaner and then restarted and installed the driver, and tried to run a game and it crashed with the same blue screen the second the game loaded, i didnt even get a chance to do anything.
