Trying to access another PC that has a bad graphics card

Need to get data from an old desktop - it's video card went bad.

Plugged in the network cable and I can see it connect to the network. Try logging on but it seems that I have forgotten my username. Any work-arounds to accessing the list of users on this so I can get to my data without replacing the video card right away? I know my password, just forgot the user name.

Thanks.
