I had just turned on the PC about twenty minutes ago and was surfing the internet when sudenly it became very loud. I hit control-Alt-delete and went to the processes tab. For some reason the CPU usage just shot up when I was on the net to approximately 58%. I let it sit at the desktop for awhile but no change. I ran a few maintenance tools but no real effect. Finally, I restarted the computer. It still seemed to run high through the reboot process but went down when I got to the desktop. I have a AMD Dual-Core CPU. 1) Is this a problem or am I freaking out over nothing? 2) If this is a problem of some sort, what can I do to fix it? Thank you.
