Bios booting but buggy

[LosNir]

Hey,
When i woke up today, i saw my computer is turned off.
I turned it on and it boots, but it stucks!

the bios stucks, the keyboard is not working and i can't do anything.
The boot block is not enabled becuase the bios thinks everything fines (he boots) so i can't use any floppy.

There is a way to corrupt the data on the bios, and then the boot block will be enabled?

M/B: Asus P4SGX-MX (Socket 478)

Thanks.
