what gives? i've tried uninstalling the Drivers and reinstalling. Took out both Cards and made SURE that the Switch Card for my Mobo was inserted correctly and that a 4Pin Molex was connected to the 4Pin Connector on my Mobo. Switched the two Cards around and still the same results. It couldn't be my PSU It should be powerful enough. The only thing i haven't tried is trying out another 4Pin Molex Connector. O... and i also made sure both the CF Cables were inserted correctly. they aren't loose. Edit: also, now that i switched the Cards around they blink about 4 times and i don't know what that means. the first card in the primary slot seems to run fine. the second card's Fan doesn't seem to be running 100% Update: ok, now with these two cards in my BIOS upon POST states it felt to Boot or start-up? WTH!? Update: ok, i have taken the Card out and put it back in it's proper box. It's not the card. It may just be my PSU not giving enough power. that's same really.
