Does anyone else have Mac problems?

The Safari on my Mac book is not functioning. It opens sometimes and doesn't the other. Everytime it opens its like I won the lottery or something. Serious, it is that much of a 50/50 chance. Its so annoying. Is it just my mac or does this happen on anyone else's Mac? I got this laptop back in Oct, so it shouldn't be acting up just yet. How funny is this, it just opened up while I was typing this on my home computer.
