OP
Quoted from mattster:

I'm running RFM via Nucore and the computer appears dead: no fans, leds, nothing.
I replaced the power supply but nothing.
Jumped the power switch pins, nope.
Did the paperclip test and the PS fan runs and one led comes on on the computer.
Prior to this problem the game would often boot to a login prompt and would occasionally reset if it did boot correctly.
I have no idea where to go from here. Any suggestions? The longer this game is down the more desperate I am to play it!

Do you have a different PSU to try? bad ram may lead to random reboots but this sounds like some kind of PSU issue. Now a bad PSU can nuke you MB as well.

Quoted from mattster:

Yes, I bought a new power supply but no luck. Is replacing the MB a practical thing to do?

You can get one that will work with the cpu / and ram in there but try to boot with just the MB and psu plugged in and then start adding stuff like video / keyboard / mouse / drives.

a dead CMOS battery should not stop the system for booting but a weak one may mess up the nvram / bios settings to a point where you need to pull it / set reset cmos jumper.

I have fixed a few boards by pulling the battery to get them to boot now a bad hard drive with a power short can stop a system from booting.

Quoted from YeOldPinPlayer:

You need to eliminate your power switch as the problem too. Find the connector where it plugs into the motherboard and short those two pins together momentarily. It's nine pins on the motherboard, 4 pins & 5 pins side by side. Your switch is probably labeled PWR on pins 6&8.

That is an usb header not the front panel

Quoted from mattster:

Will do.

It's prompting me to enter F1 to skip warning or press DEL key to enter BIOS.

what warning is coming up? it's the no keyboard one that is easy to turn off.
