i am building a computer. i have a ecs kt600-a mother board, 512mb ram, xp 2700 cpu, 80gb sata hard drive, 64mb video card. i assembled everything and the board powers up but the monitor doesnt turn on. the motherboard doesnt appear to have vga port and it wont turn the monitor on by the agp add on card. i have been messing with this thing for a week. i swapped all the components to my other computer and they all work. the video card, ram, cpu, and power supply all work on my other computer. i thought it was the mother board so i had it replaced and it still does it. the mother board manual says there is a onbaord video card but there is no vga port on the motherboard. now what do i do?
