Only icons are visible after logging in to Windows Server 2003

At first, this is the problem. The logon screen turns black after you press CTRL+ALT+DELETE to log on to a Microsoft Windows Server 2003-based computer.
I visit the Microsoft site to search which luckily i found the answer and the solution is the link below.

But there's another problem. After logging in, all I can see are only icons in black screen with no labels/text in it. Even if I open Start Menu or My Computer, or any window, only icons are visible. It's weird, man and it is only the first time I encountered this kind of problem. The system is up and running. This is the application server and still, clients can connect to this server and can use the applications they needed.
Even if you will use RDP, this black screen with only icons you will see.

I think this is REGISTRY problem but what keeping me puzzled and think is that how can I edit the registry if I cannot see the text that I'm typing.

See the screenshots of the problem below:

I tried running the server in Safe Mode to check whether the screen is Normal but it was the same but it is not. It is also black screen with only icons in it.

I need it badly guys. Help me fix this problem. To all Microsoft expert out there help me fix this. What do you think guys is the problem of this and what is the solutions for this.

Any suggestions?

Thank you very much.
