Dashboard Login

I cannot get in to my dashboard. I have a wordpress blog on my own website and it is fairly new. I failed to write down my user name and password for my WP Dashboard but my Windows always remembered my login for me. Recently, my computer crashed. It had to be completely uninstalled and then everything reinstalled again. I lost my info to get in to WP.

My main problem is that when I go to log in and ask for a new password to be sent to me, it won’t take any of my three email addresses that I would’ve used. It says there is no account. I emailed support and since my blog isn’t hosted at wordpress.com they told me to post here.

Can anyone help me please? I have no clue what I’m going to do. I can’t get in to my dashboard at all. Thanks in advance!
