artifacts on screen RRS feed

  • Question

  • I just bought a new TA790GXE biostar motherboard and a XFX radeon HD 4980. For some reason there are horizonal graphics before windows even loads. Also in the motherboard starup screen which shows all the temps there are 2 big vertical pillar artifacts. Both the card and motherboard are brand new so is the hardrive psu and cpu. I also tested each stick of RAM and all work fine. Also all temps are fine

    psu 550watt
    cpu amd phenom II 955 black edition
    RAM 3gig
    card xfx ATI radeon HD 4890
    mobo biostar TA790GXE
