Recently I bought some computer parts
Gigabyte GA-M55SLI-S4 MotherBoard
e-GeForce 7900 GS Graphic Cards (2)
Anyway, the motherboard doesn't have a video output. So I connect my DVI cable into my monitor and I boot up the machine. The machine starts up and gives me 1 short beep. When I check my monitor, it just shows no signal. What should I do, I know the parts are old and what not but they work. Also I'm using a hard drive I have from another computer, it's running windows 7 64-bit.
Thanks for any help.
