ASUS M2N68-AM Plus - Not booting

[socketa]

Power supply is good
Changed BIOS Battery
Cleared CMOS Jumper
SB Power light is green
Tried two video cards

With no RAM, and Onboard Video (or video card), it cycles:
A) No display, and CPU fan shutting off in 3 seconds
Turn off by holding in power button
Turn on by pushing power button
B) Beeps long-short-short after three seconds (indicating no RAM?)
GOTO A

Same happens when RAM is inserted, except no BIOS beep or beeps.

Does this sequence of events sound familiar to anyone?

long-short-short is the usual AMI RAM bleep code.

Another dead NVidia MCP?

That was my first thought; but i hoped that the green light, and the warm heatsink, meant that it could be OK.

That's what I was thinking as well.

But maybe try system with only one RAM stick and one slot at a time, just to rule out RAM socket / CPU socket issues.

I have two of these M2N68-something boards: one only works with 1 of 2 RAM slots (the second is dead, and there is silksreen on the PCB for 2 more, but they were never installed due to the mobo being a cheaper model); the other M2N68 mobo works fine and passes all tests except when a SATA device is connected - if I connected anything to the SATA board, the mobo POSTs and then hangs. That one for sure has something wrong with its MCP.
