Lenovo G500 fails at Lenovo logo?

My laptop suddenly freezes at the Lenovo logo, without bios start, no time to hit any key; minutes and never start; then I turn it off and shake it softly and then turn it on and it works normaly. What can be loose ?

Don't continue to shake your computer it's going to ruin it open the back and check one of the two things either your fan is not spinning or your hard drive is getting stuck that's the only two things that move in your computer so those are the only two things that you have to check
