How new is it? If it's still under the original 1-year warranty, you might be best off getting it looked at at an Apple store.

Try pressing and holing the power button until you hear a beeping sound. Doing that causes a reset, it should help your problem. You might just need a fresh mount of the software.. Mark

Hey guys, thanks for the help, but i tried everything and i could not get it, and i did not have anything backed up :foot: so i had to make a very hard decision, plus my warranty is up. so i had to erase everything and start over,That SUCK but at least now my mac is running like it should and yes i bought an external hard drive
