Clarification Request
Did you bench test this computer ?

Look to be sure that you used the proper amount of motherboard mounting stands and that none are shorting out.
If you didn't bench test it on cardboard , take the MB back out of the case and strip the parts off of the MB and bench test every part to be sure everything's good.
Be sure that i7 is seated properly

I have fixed it and it will turn on now however now the monitor wont connect to the PC.

Re: won't connect

How do you mean "won't connect"?

Indeed, a monitor with only HDMI won't connect to a PC that only has VGA (or the other way around). But maybe you mean something else?

It says no signal

When I try to connect the monitor to the PC through HDMI It receives no signal it is not the monitor because it works with my laptop nor is it the cable because I tried VGA and Display Port aswell.

Re: connect

That means that the HDMI port (either the one on the motherboard or the one on the video card, you didn't tell which one you use) doesn't give a signal. The one on the motherboard should work if you remove the video card.

the 980 is fully seated and connect the 2 - 8 pin power cables as shown in this video ?
