ok i tried a few things and i am still having problems. i found an agp mx400 geforce 2 video card and tried that, and its still freezing. I also tried to reformat using 1 partition for windows and another just for camera recordings. It froze then also. Finally i disabled all the services on startup and it still locked. i am becomming a little discouraged. if noone has anymore advice i will try the cards in a different machine and see what happens. thanks
