[QUOTE="pigoo3, post: 1435638, member: 56379"] The kernel task was the file that I had a problem with as well (when my computer was diagnosed by Apple with a bad fan). The thread you linked is from someone with a Core 2 Duo cpu...this computer is only capable of a max. cpu % of 200%. You probably have a quad-core cpu...which is capable of a max. of 400%...that's why you can get a cpu use of 330% (and the other person 176%). These problems can be very difficult to diagnose...since it can be hardware or software. You best bet may be to have Apple look at it. Even though it is out of warranty...maybe they will still diagnose it for free. Then they will hopefully be able to tell you what the issue is...give you a repair quote...and you can decide if you want them to do the repair...or do it yourself. - Nick p.s. By the way. Try booting the computer from an OS install disk (hold down C key after inserting the disk, and rebooting the computer). If it is a software issue...then booting from an OS disk will isolate any software issue on your HD. If the high cpu use remains after booting from a OS disk (or maybe with a bootable USB stick)...then it's probably a hardware issue. [/QUOTE]
