Hello, I have a Powercolor Ati X800XL. It's been rebooting my computer. I finally narrowed it down to the video card. So I have 2 questions, first my card shows no sensors in the ati tool. I've tried .24 and the .25 beta. No luck. 2nd - it's defaulting the core speed to 425Mhz and the mem to 520Mhz. Everytime i boot up and look in atitool or everest it says it's running at those speeds, not the defaul 400/490. Anyone know why I don't have sensors and it's defaulting like that?
