I have a really old Windows 2003 SBS Server that on boot up displays the Windows Server logo but it's mostly blacked out. When the login screen comes up the space to enter the username, password and domain and also blacked out but I can type in them and login. As soon as it clears the login screen it brings up the desktop just fine. It's not a performance issue, it's just irritating. I have switched video cards with no positive results. Last fact - it does the same thing when remoting in.
