The original chime comes from Microsoft Windows XP, the operating system released in 2001, where a short melodic startup sound welcomed users when the computer booted. Online, creators began distorting familiar sounds into extremely loud, clipped versions, a style known as earrape, and the Windows XP version became a popular example because almost everyone recognised the melody instantly. It spread through meme videos, soundboards and short-form edits, where its sudden volume works as a joke in itself, and it remains in use as nostalgic shorthand for old computers and chaotic humour.
