Reassemble. Leave out the video card. Then try powering on. Make sure to attach your display to one of the motherboard video ports.

I'm pretty much at the point that the motherboard is dead. I've been in pc gaming for over 10+ years and I'm just not having fun or feeling comfortable fidiling with PC parts. I'm probably gonna see about getting a new motherboard and have it installed by a professional. Other than that. I appreciate all the help but I'm cutting my losses. Thank you all.
