Welcome to JustAnswer, a paid global support site. Sounds like you have either a corporate computer or you are running a domain in your environment. You will need to attach the machine to the domain that it is a part of and log in from there. Alternative, if you want to remove this computer from the domain and make it a non-domain machine, you will need to go to (on bottom right) button select Workgroups and type in a name for the workgroup (i.e. WORKGROUP) and then click OK. Ignore the login (or attempt to use your log in information for the domain). You should get a prompt Welcome to WORKGROUP and then you will be prompted to restart. Restart your computer and update me on the results.
