No signal to monitor, self built

[fantasypisces]

Hey everyone, I just built my first computer. Everything turns on (system fans, LED lights, POST beep). However, I cannot get a signal to the monitor.

The lights on the motherboard (system LED's) turn on when computer starts, I have four lights 1:Green, 2:Green, 3:Yellow, 4:Red, but then after a bit they turn off, but all other lights stay on and fans stay on. I don't know if that's important information, but was listing it just in case.

For my graphics card, at first four red lights would come on; however, that was before I had the 4-pin ATX power plugged in and was not getting a beep. Now that I am getting a beep the lights do not come on. But the fan on the card runs.

So the main problem is, I do not get a signal to the monitor. I am using a digital plug that plugs into my graphics card, I have tried both outlets neither get signal.

Specs:

MoBO: Gigabyte S-series GA-EP35-DS3L
CPU: Intel Core 2 Duo
RAM: DDRII 1066 (2 sticks) totalling 4Gigs. Dual Channel Kit
Graphics Card: ATI HD 4870x2
Power Supply: Corsair TX750W
HD: Western Digital 1TB 7200 RPM SATA 3.0Gb/s
Monitor: SAMSUNG 2253BW Black 22" 2ms(GTG) DVI Widescreen LCD Monitor


Any help on this matter is greatly appreciated!
Cheers,
~Derek

If you're getting the POST beep then it shouldn't have anything to do with the computer. Have you tried another monitor?

dont forget to plug in the power to the actual video cards and check to see if they are plugged in all the way
