Probably movies.
I bet they just wanted a way to convey to the audience that something was happening.
Could be wrong though.

modems

I don't know, hence why I am asking. The closest thing I can remember is my dad's company owning an IBM ATX clone which HDD actually sounded like a faint drum. I loved the sound of it. But no bleeps or bloops.

No, modems sounded way different, and most people in the 80s hadn't even seen one to relate their sounds with a computer.

>>60979208
motherboard post sounds still do this

>>60979339
Yeah, but that (regularly) is just a single beep, not the cacophony of sounds TV and Movies relate to "computers doing stuff".

The short answer is that reality makes for bad cinema. That's why "computing" in cinema is always so dramatic and inaccurate. You only notice because you spend too much time around computers. Unrealistic sound effects are added to all sorts of mundane scenes and you don't even notice (because that's the point).

There probably is something more behind it though
