• The screen status changes from "no signal" to "energy saving mode". BTW, I checked my DVI to VGA adapter, it works in another computer. The VGA cable, I can't replace it, it's stuck in the screen housing.
• I sense vibration and heating in both hard drives.
• The chipset heatsink seems to be heating up but it may be my imagination.

there must be something in the MB start up check list that's stopping it from posting but it remains a mystery.

Yesterday, while checking every connection with the MB's manual, I found that the speaker wire was not connected on the MB leads (orange part of the panel section if I remember right). I guess it's not my problem since I don't think it was ever connected and the computer was working well before. However, I may hear interesting diagnostic bleeps if I connect it ...

If you hook up the speaker and hear nothing when you turn it on your board is dead or shorted.
