After checking the cord, I removed the front panel to see if it was correctly pugged to the motherboard, it was. However to do this I had to unscrew quite a few things to get there. I then noticed that the green power led was lit. I tried the switch again and it worked.

Another problem now...

Is there any known issue with copy and paste in firefox, it works about 1/2 the time but I do not notice such a problem anywhere else.
