Your pc ran into a problem loop

I was on YouTube and then my PC froze and restarted. Then the blue screen showed up saying "your PC ran into a problem and needs to restart. We're just collecting some error info, and then we will restart for you. " then it goes to the Acer logo and then back to the blue screen. It keeps repeating this.
My PC didn't come with a disc or anything I have an aspire b. It is windows 8 it was so when I got it in last December. Help me.
