Have you try cleaning RAMs and GPU? I changed my PSU and it wouldn't boot into bios with a led on the boot. End up just cleaning the connector of each RAM stick and it work like a charm.

Would you mind sharing more on what's happening? Does it refuse to power on anymore? Do you get some sort of error message? What kind of power supply do you have?
It powers on fine. The only error is post that I can see because I can't use the mo it or to see anything else. There is no onboard graphics so the monitor isn't usable.
Power supply I put in the post, it's 750W modular.
Agreed, usually for troubleshooting you strip it down to the bare essentials if it isn't booting. 1 stick of ram, no hard drive, some type of graphics. Getting it as simple as possible so you are removing variables.
I've seen mice that prevent a computer from posting, so sometimes it's really weird causes.
Honestly, I'm wondering at this point if I shouldn't just get another motherboard. This one doesn't have onboard graphics, so I have no way to do what you're saying. My mouse is Bluetooth so it's not even in the same room anymore. I only have access to a laptop now, so I can't even put the hardware in a different computer to test it.
I was actually going to ask if you had another one. Sometimes it isn't the card, it is the slot or a controller. If you have access to another board you can rule that out.
I've basically come to the conclusion that a new motherboard is necessary. Should I assume this was a one off and get the same one, or try a different one?
You mentioned beeps. Can you describe them for us? How many, how long? Are there any visible lights anywhere flashing?
