Lost password and login.

You don't remember your user name?

What do you MEAN

"I recently lost computer power and my login/password info"

WHERE did you have it stored? If example, you have your login stuff stored in a text file IT IS STILL on the hard drive unless the hard drive suffered a massive failure. Even if the rest of the computer died, the hard drive might work.

You can buy -for very little money, a dongle which works like an external hard drive. It is a "head" with connectors for different types of hard drives, a power supply, and goes to a USB port. You plug your old drive into the dongle, plug the dongle into another computer, and you can access the original hard drive.

Here are some of those devices

Ya know, it might be time to get on Google, and learn how to "back up" some things.
