My DELL Laptop keeps going up to 100% CPU usage. I'm not sure what itis. Seems that when I close IE7, it will go down. However, the problem will come back again later. Could it be my temps? I installed coretemp and it's reading 77 and 79 on the cores right now, but now it just dropped back to 62 and 63. 79 was the highest I've seen it read, but I'm not sure how accurate the core temp readings are. I'm running Vista Ultimate by the way.
