Window xp old version error: User interface failure. The login user interface DLL MSGINA.dll failed

I used a Spy Sweeper to clear out adware/spyware on my older

Dell Dimension 4100. Coincidently, it seems to have created a problem

of user interface failure at start up. I am getting this message: "The

login user interface DLL msgina.dll failed to load Contact your

system administrator to repiar DLL.OR restore the original DLL"

I am able to get into the BIOS. I don't have the original Dells restore disk. I do have Windows Professional xp

software to restore. What steps can I take to access this computer.

Thanks on any help you can give me,

Harry
