I have tried repairing permissions, rebooting, verify disk and onyx. I do not have many apps installed, no login items, 5 items on desktop, 107gb left on my hd, no antivirus, and nothing processor or memory intensive running. Also, when i try to delete custom prefpanes sysyem prefernces freezes with the spinning wheel. Some apps (mainly keynote) often freeze unexpectedly causing me to lose all my work. Sorry if this is the wrong forum this is my second thread.
