Save everything to a hard drive or sommit then get win 7

I already have Windows 7. I built my computer and I'd rather not redo it. I don't keep personal things on this computer other than World of warcraft or sims 3... which could always be re-installed? Right?
I have tried everything from cmd, to safe mode. Nothing works. So my best option i have left is figuring out if i can use a floppy disk or usb.. My father told me i would've needed that when creating the password. ..Hope not.. I don't have any of those freely around the desk so I will most likely have to just think hard of the password.. Because I hate being limited on a guest account.
