Toshiba laptop won't start past the leading innovation screen?

My l55t-a5290 toshiba laptop (less than 2 years old) won't start past the first screen. It just replays over again. And no command buttons will work. I was editing a video in Adobe premier when it shut off suddenly and started doing this. My friend thinks it is from overheating. What can I do?

Remove the ram and put it back in then retry if it still won't go further remove the hard drive and see if it will post to bios if it will its a bad hard drive.

If it won't its a toasted mother board!

Now here's why they burn out.

Setting your laptop on the bed the couch the rug or a tablecloth plugs up the little fan port on the bottom and your PC Fry's!

Buy a lenovo they don't have that problem
