Try zapping your PRAM
1. Restart your computer while holding down the keys Command+Option+P+R.
2. Wait for your computer to chime twice before releasing the keys.
The screen will flash when the PRAM resets.
OR,
try safe mode (for some reason it's worked for me before):
hold shift down while booting
