It's quite clear that this is a hardware failure. I tested a live CD and PXE booting on it with the same problem before buying the new card. I also tested the system disk fine in another machine. It's got nothing to do with the system, although it happened right after the update/reboot. So, other than replacing the mobo, it *is* the solution. Mobo might be going haywire next as well, but currently it's absolutely stable. And I have a backup now in case it wants to go ... Kai
