Hello, sorry for the issues you experienced so far, and I see why you need to use a CD instead of USB.
According to your number 3 above, that is a little too weird (It's a regular login screen in Windows, right? Nothing stranger looking?) If so, it looks like somebody else had access to the computer, and made that account somehow.
It could possibly be a hacker out there that locked your computer like so, yet if they did something like that, they would most likely have tried to contact you to ask you to pay them so they give you the password. Rule of thumb: Never EVER make a payment to a hacker to get a password to unlock your machine. They will keep asking for more and more money, and, most likely, never unlocking your computer, if they notice they can keep mining money off you.
-> Ask if anyone you know may have accessed the computer and locked it.
As another idea, you can salvage the files off it if you remove the drive, and attach it to another computer as a secondary drive (using an external encasement). Connect it in a Linux based OS (the boot CDs), so no hacks/viruses/etc don't accidentally get transferred to another Windows PC. And before transferring files, virus scan them.
