actually like i said already it is the hard drive, a bad hard drive can be a reason of bios freezing, because the bios can't read the hard disk properly. like i said you already got your hint that when the bios freeze or hangs your hard disk become noisy, it means that the bios is forcing the hard drive to be read. this already happened to me 3 times on my customer's computer.
