Dell 14z would not boot past logo screen. Help plz!

I bought a new inspiron 14z just 3 months ago and now it woudnt even boot past the logo screen. I tried pressing F2 or F12 and nothing happens. It just stays that way then restarts to the same logo screen again. 

2 days before this happened I had trouble putting it to sleep/hibernate/shutdown. the screen would go blank but the power light would still be on. I tried updating all my divers and bios and still the same problem. Then i did a system restore to a few weeks earlier and the next time i tried to shut it down it never booted up again. 

Can anyone tell me what else I can do? I am not in a position to use my warranty (not at home and there is no Dell center nearby)
