Windows – What explains the garbled message “Start Wandows Ngrmadly” in text mode?

When booting up Windows, why would it say “Start Wandows Ngrmadly”, instead of “Start Windows Normally”?

I tried googling for an explanation, but came across too many hits of people merely ROFLing at it.

Solution:

This looks a lot like a memory issue (or at least a glitch, since it doesn’t repeat everywhere), a bad video card (I remember having this problem once, turned out to be dying capacitors in the video card) or a corrupted file. What happens is that one of the bits in the character is getting toggled.

From an ASCII character table, we can see that i is character code 105 (1101001 in binary) while  a is character code 97 (1100001 in binary). A difference of 8 (i.e. the 4rd least significant bit).

You can notice the same happens for other characters: d in ASCII is character code 100 and l in ASCII is character code 108.
