Hello doctor,

Go back through, checking all cables - make sure they are secure, triple check that they are plugged in all the way, and that they are in the correct plugs. Reseat your graphics card, your memory, and everything. Make it snug. retrace and go over everything you replaced to make sure it is fully plugged in. Let me know if you can see anything after this.

Did you apply new thermal paste to your CPU? Is your CPU fan connected to the CPU fan port on the motherboard (specific, won't let the computer start unless it is).

Are you hooking the monitor up through the motherboard or the video card.

Yes. There's a specific white 4 pin port for the CPU. All of the fans are definitely running, and I will try what you said, thanks.
