Wavy lines

[johny5]

I've got my pc hooked up to my tv, have done for some time, but today when i put it on its got wavy lines all over the screen,

The tv's fine when i'm watching sky or ps3,

So dont know why i'm asking coz it sounds like me graphics card, but could it be anything else before i start ripping it out.

Check the connections at both end a firmly pushed in, and also make sure the cable for the picture isn't routed right next to a power cable.

Found out the problem, dont know why but after a year of having no problems all of a sudden me sky and the aerial off the roof are interfering with me pc.

So i've unplugged me sky and tv aerial and its fine.
