Ok get comfy

Right so back in November i bought a new graphics card (amd radeon 7950) and i installed it into my PC and it didn't work so i switched back to my amd radeon 6670 witch works fine so after a few weeks for Christmas i got an 880w power supply now i thought this was the problem but still it dose not work so i take my PC to my friends so his dad can have a go and for some reason it worked there he was using a dvi cable and an hdmi (i use a vga with a dvi adapter and also an hdmi) but after i got home and plugged my PC in to my monitors it didnt work anymore.

Please help thanks
