First time arcade owner, so I'm still learning how these operate. Does anyone have some insight for how to correct this error on Big Buck Hunter Pro?

I replaced the CR2032 battery on the mobo and updated the BIOS per the manual. (With the exception of "advanced chip set features > PMU > CPU frequency" as I could not locate it.

All fans run, and the dongle lights up on the computer. I/O board has 6 red lights on, two of which toggle back and forth.

I was reading it could be due to a bad/weak power supply, and that the watchdog adapter harness might be the culprit?

Thanks in advance!
