Figured out what the problem was. It was the overclocking of my AMD proc. I just added the 6800 GT into the system a couple days ago so the power supply must not be able to handle both a 200 mhz overclock as well as the 6800 GT. Once I set the AMD 64 3000 back down to 2 GHZ the freezes stopped. I would like to bring it back up to 2.2 GHZ again however, is there some tweaking I can do with the voltages to make this happen?
