I use windows 7. Maybe the hard drive is bad and causing the problem. Remove it from the laptop and install back in. Is it a guarantee that taking it out and replacing will reset the BIOS password? If one of the USB ports still works but 2 other ports do not work, probably this is hard ware related issue. One of the memory modules could be bad.
