Hi,
from a few days I am happy owner of GT780, maybe not quite as it turns out that the machine out of the box causes problems.
Specifically:
If the BIOS is set to USB LEGACY SUPPORT ENABLED booting any OS (Windows 7, Ubuntu, XP,...) freeze on boot screen, but ONLY if any USB device (even a mouse!) is connected to any port or there is disc in DVD. After disabling this option, everything is working fine, but the point here is that the equipment of this price range should support the keyboard in DOS, right?

Has anyone met with this problem? Let me add that the BIOS is the latest version (release from October).

I tried different devices: mouse, pendrive, external disc. Interesting is that the disc (CD/DVD) in the drive gives this same result.
When i try boot Ubuntu from pendrive (btw. usb devices are correctly reconized in BIOS and boot menu) its freeze on USB initializing. Boot Windows XP live cd is imposible too (bluescreen).

BIOS detecting 2 internal USB hubs but there is no way to switch off them.

Btw. thank for response :)
