Hummmmm... the only other code I can think of with 3 long beeps is keyboard or keyboard card error, but if that was the case you would see that on screen. Have you tried the simple rule and load optimized default in the bios?

Yeah one of the first things I tried, many times. I'm going to try out a more beefy PSU tomorrow and see if that helps.

1 short: System boots successfully
2 short: CMOS setting error
1 long, 1 short: Memory or motherboard error
1 long, 2 short: Monitor or graphics card error
1 long, 3 short: Keyboard error
1 long, 9 short: BIOS ROM error
Continuous long beeps: Graphics card not inserted properly
Continuous short beeps: Power error

Sounds like keyboard to me, but many of these can mean other things and or be caused by other things, so it's hard to say
