Laptop turns on, but not really...

Just recently I've started having this issue with my laptop where I turn it on and it lights up and everything like it is going to turn on, but then it just keeps rebooting. The screen never turns on either. It just stays black. I'm not sure what the problem is, if I try again later it works fine. Is it overheating or am I missing something?

I'm using an HP Pavilion if that helps any.
