Hrm, I have a athalon cpu, I think they can stay fine to like 90 celcius. Mine rarely goes above 100 farenheit though (thanks to my ingenius window fan blowing on cpu cooling system =. I check for it regularly, to make sure it's cool (bios informs me of system and cpu temps). I'll check for the dust n stuff, don't wanna fry anything heh. I'm thinking that it's some kind of IRQ conflict or something with my graphics card, thanks for the help so far =) edit: could you tell me more about how yor sb live is set up? Drivers, othr stuff installed with it, IRQ, etc?
