Hmm sympathy vote from me too Zpos.
My machine has entered a new state of wierdness as well. Managed to get it to reinstall windows fine, downloaded a couple of new drivers for chipset etc from their website as per the advice in the stickied thread for Gigabyte boards then Internet Explorer stopped working and would hang on opening....
tried downloading and reinstalling LAN drivers from the website via another computer... no change... so figured I would just reinstall windows again and start from scratch only NOW it gets to windows setup and says it cannot detect any hard drives installed and so cannot setup windows. I have not changed any bios settings from the working install I had previously - how odd!
[Edit] Seems a bios setting had been changed to put sata mode into AHCI rather than IDE - changed back and is now reloading windows
What I did manage to do however whilst the windows install was up, was run CPU-Z, Orthos and Memtest86
Nothing untoward on either core in CPU-Z, Orthos blend test ran happily with zero errors for over 3 hours and I left memtest running overnight for more than 8 hours with zero errors - so something definitely seems up with the mobo rather than any ram, cpu etc.
The thing appears to have a personality - and an unpleasantly changeable one at that
