Continous PPPP's without me touching anything

[Lisak]

I am using a wireless keyboard (second one as I thought the first one was faulty). Suddenly, and with no warning my screen starts to develop a continuous row of capital P's and the only way to stop it is to unplug the remote keyboard dongle and revert to using my laptop keyboard. Any suggestions?

Try another USB port. If it has software (drivers) reinstall it. Pry the "P" key off and see if there is any dirt under it.
