ok so this is my first time using DVI-cable anything, I just got a new graphics card and installed it and i got no signal i thought it was the graphics card but now im thinking its the dvi. I just bought a dvi cable and plugged it in to my monitor and my motherboard without the graphics card installed. and i get no signal. so i switch back to my vga and everyhting works fine. I change the monitor settings to dvi and it says no signal. My monitor is an AOC e2243fwk. i have an amd a8 5600k apu. and an ASUS f2 a55-m lk plus mobo. i need help with this please i have been searching all day for solutions. the dvi cable is the one with all the pins and then a wide single pin at the end.
