Error right after installing

I get this error once i have submitted login/generated pass
after installing to web server:

“Found
The document has moved here.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.”

This error is now found throughout site, but mostly related to wp-login.php

I was running a pretty smooth install of wordpress until yesterday when i had to remove it, as browser suddenly came up blank when you surfed the url.
