Boot with bootflags -s -f -v (clover bootscreen use your spacebar) log in with guest and make a New user with admin right, log out guest. Log in New user, use kext utility and don't use auto log in.

I think something to do with sleep mode. I had this problem 1 time. For now no more.

For all those lost souls out there, chk out the link given below. It worked like a charm for me. Guess what, its an OSX bug!!

I've tried a lot of solutions with no luck. But only this one work like a charm!

I'll put it here just in case.

1. Shut the computer down by holding the power button for 10 seconds

2. Restart the computer and press shift at the same time until you see the progress bar start moving

3. Once you reach the point where your screen goes dark and you see the cursor, type the first letter of the username for your computer, then hit Enter, then type your password, then hit Enter.

4. After a moment, you should see the spinning beach ball

5. Your screen should then move on to something along the lines of "Completing OSX Installation" (I can't remember the exact wording). Let it finish. After that it should go to your normal desktop and the issue should be fixed. (If your screen goes pitch black during this process, hit the space bar. I thought it wasn't working, but the screen was just sleeping).
