ASUS WS motherboard woes

[DDebbil]

I'm trying to test an ASUS P9X79-E WS motherboard, but it is throwing out intermittent faults when I change the SATA port used to boot and the PCI-E slot used for the graphics card. Occasionally, the board is refusing to start the graphics card or starts it but seems to crash upon loading Windows, and will then display an 'overclocking failed' message on next boot. Just now, it seemed to do the same, but on the next boot, there was no display and the Q-Code LED readout was not showing anything at all, and the board could only be brought back to working by clearing the BIOS.

This thing is doing my head in because it seems to work fine for 10 boots with different SATA and PCI-E slots and I think "Oh it's working after all", but then it will do this faulty behaviour again.

Can anyone suggest anything that I can do here?

Undo the overclock ( or reset the Bios ) first and see if it is stable after that.

it could be a voltage regulation problem.

There was never any overclock. It's a bizarre message it throws out when it's misbehaving.
