Computer Freezing With Sleep & Refusing Restart
Last night I shut down my iMac and went to bed, woke up and when it restarted; it froze on a blank gray/white screen. The cursor was present with a phalanx of little black bars along with it. I restarted the computer in safety mode and it works; however no sound and couldn't really do much. So I did a regular restart and the computer has been operating fine, the cursor looked normal too. Until I took a shower, it fell asleep, I came back, and it was frozen again. The cursor could move about with it's little phalanx but I couldn't do anything.
My mac will now only start with safety and won't get out and I'm afraid if I shut it down/sleep it I basically will have to go through a complicated ballet every time for it to function properly. What can I do?
Mac OS X Lion v10.7.5
Early 2008 model
Processor 2.66GHz Intel Core 2 Duo
This is what I'm talking about for the cursor:
iMac, Mac OS X (10.7.4)
