Hello,
my hp 530 wont boot up to window,freez up after hp invent
If the problem is windows, take out your hard drive, connect it to another computer through USB (buy connector first), back up your files, then do a fresh install using your Windows CD.
Right now I think your problem is Windows simply because no information has been provided.
Try providing some more information, for example do you hear any beeps? Have you changed any hardware or software recently in your computer? etc..
