My MacBook Pro 2.66GHz has been running at 40% of the CPU ever since this afternoon. It usually idles around 10% or so. Funny thing is... when I go into Activity Monitor, and show all processes, it only adds up to about 10%, but there is an extra 30% being generated somewhere and it's heating up the computer from the normal 59C to 71C and the fans from the usual 2000rpm to almost 4000rpm now. I have tried resetting the SMC three times, resetting the PRAM three times, and I have repaired permissions and rebooted a few times. It starts off fine when I log in, but then it goes up to about 40% CPU usage after a few minutes of doing nothing. I even tried making a new account.. it's the same when I login to the new account. The fans spin up and CPU usage is around 40% There's a picture. The processes do not add up to 40%. Anyone know what's wrong with this?? Btw, this is the second time it happened.. the first time it happened, I did an archive and install and it was still there. Then I rebooted, and it was gone. It reappeared again today.
