Hey guys I really need your help. So I'm building/repairing this computer of my friends because he doesn't need it anymore because he got a brand new one and he said something was wrong with it so we checked and plugged it into my monitor and it seemed to turn on fine, connected to the monitor but it wouldn't stay on. Well I just fixed it where it stays on in fact it's on right now and has been for about 7 minutes now. But the only problem is now it won't connect to any monitor. I plugged it into the only monitor I have and I plugged it into my TV through my HDMI cable but neither work. The monitor works perfectly fine because I was literally just using it to set up dual displays through my laptop. And I know there's nothing wrong with the HDMI through the TV because I use HDMI for my Xbox. I really need your help guys because this laptop is old and dying and my other PC just died a few days ago. If someone could help that would be so great.

I should probably add that right now the motherboard is not currently in the case. I have it out because it's a pain having to put it in the case and take it right back out just to do something or test something.
