My Computer Wont Boot Up!!

[mikevs]

So I was browsing the Internet, and my computer froze, I tried to restart and the computer would not go through the normal boot phase, or beeps. My HDD light flashes and that's it. My computer screen goes blank and goes into hibernate mode.

I opened my computer and checked all the cables, which are all fine and connected. I don't know what the problem is. I have no viruses or spyware at all and recently defragged my computer with Smart Defrag 2 which I never had problems in the past. Can Anyone Help? Thanks
