Video ports on motherboard do not function

[superstevenyc]

I build a custom computer. All the fans are functional, I installed everything and can not get a display on any monitor. I tried with the video card and without. I used several different functional monitors and a HD Television with the same results.

How does one know if the motherboard is fried?
How can I determine the problem?

It would be helpful to detail the components.
In these cases it's good to test the board with a minimum configuration.

Be sure to hook up the internal speaker. It could be giving off beep codes, which would tell you what the problem is.

Make sure the MB speaker is hooked up. There will be various patterns of long and short beeps documented in the motherboard manual for different errors.
