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.

In initial post you said, you just replaced thermal paste.
To do that, there was no need for disconnecting any front panel cables or removing cpu from socket.
BTW - cpu socket pins are extremely tiny and fragile. Very easy to damage them.

Did you also replace some parts in your pc?

 

[ISShadowI]

Only thing replaced was the case and psu and thermal paste. Could sweat damage my motherboard?

 

[COLGeek]

Case. That is new.

When you installed the motherboard, were there any extra/unused mounting points/standoffs under the motherboard?

 

[ISShadowI]

Would it be the cpu aio cooler backplate be an issue? I don't remember any extra or unused mounting points or standoff. I left most of the compenets like ram and cpu on the motherboard. Took off the gpu and that is about all I remember. Would taking the board out and examining the back be worth it?

Yes. You'll have to do to replace the motherboard anyway.

Were you dripping sweat onto your motherboard?
If drops of sweat have fell into exposed cpu socket, that certainly could cause problems.

 

[ISShadowI]

Not into the cpu socket no. I live in FL so it's hot here all the time. I'm in the process of removing the board and examining it.

PSU replacement is a pretty big deal.
Where both PSUs modular? From what model to what model?
Did you replace all modular PSU cables to new PSU cables?

Modular PSU cables are not compatible between different model PSUs.
Using wrong cables can kill / damage hardware connected.

I used a corsair rm1000x psu. Fully modular psu. Used all the cables that came with it.

Big update. Took the board out and did some investigating. Took my m.2 drives out and one stick memory left in. Plugged in the connectors to the psu and it powered on when I pressed the power button. Making progress here.
