Power down the mac completely. Then Press the power button and hold down APPLE-S
When the text stops scrolling type fsck -f and then press enter
Wait for the process to finish (it will say something about root#) and then type reboot and hit enter.
Then report back and tell if it helped or not
Oh, and by the way, try posting with a more descriptive title please!
