Which board is this?
Can you please post the AA number for the board?
You may get the AA number from the bios sometimes.
However if the board is booting, you can try the Intel Board ID utility.
If you can still go into the bios, what is the bios version, full string would be better to have.
Then go to Additional System Information >> Desktop Board Information
Try the Intel Tool called Intel Desktop Utilities, you may find the board model.
All the best,
Actually, the motherboard isn't from Intel, Asus I guess, I'll check the model tonight if it matters.
Everything is back after a reboot (using shutdown command to restart remotely without RDC/TSE connection).
