*ANOTHER UPDATE*
Tried the latest drivers by themselves and still had the same results. I ran a scan through the driver agent site, and it okayed the video card. I went ahead and updated my monitor drivers while I was at it. still the same results.
I also noticed that a red LED lights up on the card whenever I try to run Crysis. I highly doubt this is a power issue, though, since I was running the same PSU and video card since before I replaced the motherboard.
Again, everything runs fine until i try to start the game.
