This seems to always be involved. When I try to play an MP3 using WMP all the tracks get a red apostraphy. It then says that their may be a problem with my sound card or something else may be using it. But there is nothing wrong with my sound card.
When I go to shut down the pc it plays the shut down jungle, just to further annoy me.
Please can you help, I have also had a history of viruses and spyware destroyed by your help.
