Hi guys. My problem is that i cant use a keyboard and mouse in the bios at any usb and ps2 port. First time i see something like that. All ports working fine in windows. They are working also fine just before you go in to the bios (you can click "del" to go in to the bios no problem). Bios is not freeze (you can see changing cpu temp.). Only thing you can do in bios is press ctrl+alt+del and then it will restart but you cant do anything else. I tried both new bios versions from Msi website 1.7 and 1.8 nothing changed. Tried ps2 keyboard no changed. I removed ESD protecion component from one of the port - nothing changed. Question is - is it some kind of wierd HUB malfunction or some of You had any ideas where to dig? Thank you for any help in advance.

FASTB1: GO2BIOS Button
If you enable the "MSI Fast Boot" feature in BIOS, the keyboard will be unavaiable and
entering BIOS Setup by pressing DEL will not function. Once you press this button,
the system will enter BIOS setup directly at next boot.

There is no problem go in to the bios, i can do it every time. Problem is that i can not do anything inside the bios (there is no mouse cursor and keyboard doesnt respond). Only what i can do inside a bios is press "ctrl+alt+del" and then it will restart, nothing else works. It looks like is locked from editing somehow but how???? Becouse of that i cant modyfi anything in the bios.
