1 Answer

Answer :

I had a similar problem that was corrected when I reset the PRAM. Another alternative (after that one) is to restart in safe mode, and then restart the computer. But, I think the PRAM reset should work. If you search the web, you’ll see you are not alone, and that a PRAM reset should do the trick.
