I have acquired a Sony Vaio PCV-RX450 that will not install ANY OS correctly. It will boot via CD, but only get about halfway through the install process before the CD spins down and the progress bar/current file copy status (the bar at the bottom. e.g. "Copying: dvdplay.exe"). I am installing Microsoft Windows XP Home, but I have tried XP Pro and Win2k as well. Does my BIOS need upgrading? I haven't tried switching out CD drives yet, but I am in the process of doing so. I have also tried installing the OS in another PC that will install, but all the Viao will give me is a blank screen. Any extra info you need, I will gladly give you.
