i've setup a desktop for my friend with an asus p5q-e mobo & hd5770 grafix card all being powered by corsair tx750 psu but when i turn the computer on nothing come's up on the lcd (dvi to vga connection) but the desktop post's and boots right into windows. when ever i try other cards they all work and the lcd will come up but its just this hd5770 card. the strange thing is that when i try this card in another comouter it worked just fine. any suggestions?
