The card worked for a while, when I first installed it. When I powered down the system, and didn't turn it back on until the next day, I would get no video on boot. It simply does not work anymore, no matter what I try. There is no video at all at boot, and there are no beeps from the motherboard either. I'm sure the card is firmly in the AGP slot. I hear that the Prophet II Pro cards don't work with KT7 motherboards, but I have one of the newer cards, its serial number is 5058481. Also, it worked for a short time, long enough for me to bench it and get over 8000 3DMarks. I called tech support, and they said that I could mail the card back, but before I do it I want to know if anybody has been able to find a way around this problem...please help, I'm tired of using my TNT2 Ultra!
