Computer video card problem ????

I got a custom made computer with windows xp a nvdia n force 2 graphics chip unknown video card. I am not 100% sure of the problem but im thinking maybe its the videocard this is what is doing. On 2 different monors 1 showing that something is going on with the comp according to the self check and the 2nd just goes to the orange light which i believe tells us that its not getting a signal. the computer i can hear is running cpu hard drive etc i can hear it going but i cannot see anything on the screen. any ideas what it might be.|||Did the problem started happening from the nowhere?



You can try plugging your monitor to the integrated video card of the motherboard. 90 percent of computers come with their own video card, give it a try and if it works now you will be sure what is the issue.
