No go :-( Have you connected a self-powered USB hub to the system? I also noticed (on some other computers) major problems during cold boot when the USB hub provides power not only to its downstream ports but also to the upstream host port. This way the mainboard will get some power even when it should be completely turned off. It took me quite a long time to find out that nowadays cheap USB hubs do not have proper power supplies (e.g. a Schottky diode on the upstream port) which prevent such behaviour. Also some self-powered USB devices behave strange during enumeration done by the BIOS which also caused a hanging system during early boot stages. One of my computers (Asus P5Q Pro mainboard) didn't boot in all cases when the mouse was connected to a USB hub integrated into one of the TFT monitors. Connecting it directly to the PC (resp. it root hub) solved the problem. After a BIOS update the problem vanished. So you should try to disconnect all(!) USB devices from the computer in order to find out if they cause the problems. Regards Andreas Schweigstill -- Dipl.-Phys.
