Lately it's been running super slow. Adobe programs lock up left and right, the browsers lock up, music skips, YouTube freezes, flash barely runs. Even keynote has been locking up lately. I've run the Apple Memory test off the boot CD as well as various HD tests, everything passes with no issues. Anyone have any idea what this could be? I'd go to my local Apple store, but I have a week of finals left and being a design student can't be without my machine.
