I would seriously consider an Archive and Install for this problem.
Something is seriously screwy
After my Mac froze up. Then I restarted it, all the text on the desktop turned to just "A"s. (All the text on the desktop files and folders are just a lot of "A"s. All the text on the desktop menus are also just "A"s.
For example the top menu bar on the desktop looks like the following:
AAAAAA AAAA AAAA AAAA AAAAAAA AAAAAAAAA AAAAAAA AAAA
All the "A"s have boxes around each letter.
The computer is an old G4 with osx 10.4.11.
Does anyone have an idea how to fix this problem?
