P.C disrupting Freeview signal

[Legionaire68]

My P.C is scrambling my Freeview on both my digital t.v's and my recorder. Its only when I start to play a game in desktop its fine. I was on Sky at previous address and that was fine! Does anyone have any ideas about this?

The aerial cable needs to be better quality, I would recommend using some Webro WF100.

Also if you have any outlet plates or joins make sure these are fully screened.
