Compaq Presario s3200nx can't turn on.

Here's the story how it doesn't turn on...

I was charging my ipod and I accidentally pull the usb plug with my feet and then my Compaq Presario s3200nx turned off... I opened my CPU and tried looking if there's something wrong but it looks like it's fine. Now everytime I turn my Compaq Presario s3200nx on all the fans just rotates a little bit.

So can anyone help me how to fix this?

Please and thanks in advance =D
