Well, it did it again when I started up. It just kept going for about 10 minutes, but it eventually quieted down. I just played Far Cry for about an hour or so, and the temperatures were great. I didn't check the video card, but my CPU never went above 46 Celsius, motherboard never went above 33 Celsius (with the fan on it), and HDD never went above 29 Celsius. I can tell, though, that the video card isn't slowing down as much as it used to. I'm going to reinstall the newest drivers, though, and see if that helps. It just might!
