I've done everything I can think of to troubleshoot this issue, but I'm still getting a "No Signal" message when I connect via DisplayPort. I've powered down and unplugged my system, reseated my RAM (even tried using just one stick), and checked that my GPU and its connections are secure. I verified that I'm plugged into the GPU instead of the motherboard. My BIOS starts up and shows the boot drive correctly, but as soon as I try to boot from it, the monitor goes blank. Unfortunately, I can't test with another GPU or a different monitor. Any ideas on what could be causing this issue?

You might want to try clearing your CMOS or removing the battery for a few minutes, then powering it back on. It sounds like you've done a lot of good troubleshooting already. Also, double-check your cooler; sometimes the mounting can shift, especially with newer CPUs. If it's been a while since you applied thermal paste, that could also be worth looking into.
Did you install an OS yet? Make sure that’s done because it could be an issue if your BIOS sees the boot drive but isn't booting from it properly.
Yeah, I've got an OS installed. The BIOS shows it, but the monitor says 'No Signal' as soon as I try to boot.

I wish it was an old system. Everything’s brand new! I’ll be bummed if the battery is already dead.
