Yeah...it's showing ~60% CPU usage at any given time. No process is using it, system idle process is showing it's usual 99. I've tried a system restore, no luck. my CPU is the Athlon 3200+ socket 939. oh, and this problem happened randomly, it was working fine one night, and i leave myc omputer on and wake up to see this. no idea what to do, i'd prefer to not have to format/reinstall windows.
