Admin account corrupted and cant access files using Admin p/w

[curtfh]

Hi guys when my pc gets to the first screen where you choose your account my admin account has changed from my name to 'Other user' and when I click on it it asks for a username and password. Also trying to access files from the admin account when it prompts me with a password I enter it and the dialogue box goes away as if it has accepted the password but does not let me access the files. Any help appreciated thanks.

You could try http://www.sevenforums.com/tutorials/507-built-administrator-account-enable-disable.html
Then make yourself a new admin account then disable the built in one, it sounds like yours has been corrupted
