So i put my powerbook to sleep last night. Woke up this morning, put it in my bag and came here to class. Was trying to get onto our schools airport network and it wouldnt go, so i just rebooted. Upon reboot osx loaded only my dock. nothing else. not even the top taskbar, no clock/battery/airport. I just had a spinning beachball of doom. I clicked on the system prefs icon on the dock and was able to open it. So i decided must be a glictch so I rebooted. Same thing happened. Finally about 10 mins later my icons and the top task bar came up and i was able to get online. Anyone have any ideas? time for a format? What should I try?
