Hi, my brothers computer from Time is not working anymore has a result of the hard drive failing (so I though). Initially the BIOS does not recognise the hard drive at all so I tried a brand new Seagate barracuda 160GB which is the exact same has the one before and it still don’t recognise it could it be a virus that inflicted the actual BIOS? Is it possible to re-install the BIOS? Thanks in advance
