Hi I'll guve this another shot.
You NEED to describe the picture and any other info that is displayed with it.
I have resources but without a description of the offending LOGO splash screen, I cannot get answers.
Now you made reference to the Tongue is stuck picture, is that what it's called ?
From what I understand, your start up and shut down screens have been rel[paced with this new picture is that right, or do you see it AS WELL as the startup and shutdown screens?
If Win98 the normal startup logo is in C:/logo.sys. This may have been replaced.
I don't know what operating system you have, Win98, 2000, XP or?
TuneUp Utilities lest you disable startup and shut down screens, speed up your PC by removing menu animations etc.
You can download at http://www.tuneup.de
If disbling the start menu splash screen fixes the problem, you just need that file replaced.
You can run System File Checker to either extract a single file or auto scan for changed or deleted system files. This MAY replace the original logos.
Just click STAT>RUN and Type sfc.exe then Enter.
If not, a simpler way to do this is to download an editor for yor startup and shutdown logos.
