MB won't boot; fans just 'twitch' -- AOpen AK79 G Max

Hi -- I switched this MB into another case; in the old case, it and all
periphs worked fine. while I was doing the change-over, I added RAM. Now,
it won't work.

When I turn on the power supply switch, the red -protect-your-CPU LED comes
on, but, when I push my front-panel ON-switch, the fans don't start and
there is no boot -- the fans just 'twitch' once, and then stop. To re-try a
boot, I must unplug the power supply at the cord.

I've tried everything I can think of; even talked to AOpen tech supp, and
they replaced my board -- ; I still have the same symptoms.

I'm using an AMD 64. Thx for your help. -- Bob

Weak/bad PSU, CPU fan not plugged into proper header (MB doesn't see cpu
fan). But if you have to unplug the PSU to try and boot again, my guess
would be it's going into imediate overload and shutting down.

I didn't have a proper/complete/snug connection between my CPU and it's
heatsink/fan combo.
