I'm pretty sure my video card is dead. I can hear log in sounds, start up sounds etc but the video has now completely gone. I've bought a new car compatible with my computer but don't want to unwrap it and that unless I know it will definitely sort out the problem. I had blue lines and all those wierd artefacts for ages and then I smelt burning a few times and eventually it just went completely. So, the card I have in my computer which has the dvi ports has the name 'Asus 213219'. The computer is a Hp Media Center PC m700 m7520.uk. If I replace this card, that is just the graphics card that uk replacing yes? The one I bought to replace it is perfectly compatible with the computer, but is it likely to fix the problem?

Could is be another problem and not the GPU? Possibly. The motherboard could be the issue but I think with your situation, the graphics card is more likely.
