So I tried to turn on my computer

AND IT'S DEAD!!! So I am on a laptop for now and am hoping when I go downstairs that miraculously my computer will start...I think it is way under warranty and can only think it is a hardrive failure cause I am too anal to let anyone else use it so know there has been nothing downloaded or installed...nada, nil, nothing and I have really good antivirus protection....booo hooo... I just hate this. So here is to keeping my fingers crossed and I am hoping... even praying that it works, it's pretty new...damn Vista!
