I just finished putting together my new computer and installed WinXP Pro cleanly, but ran into a few problems. I am running a single WD800JB hard drive, and set up a 10GB partition on which to install Windows, but the rest of the hard drive does not show up anywhere. I know that only the 10GB partition was formatted, but I can't figure out how to format the rest of the drive. I heard no startup sound from Windows when it opened, but I did hear the ASUS POST reporter voice (mobo is A7N8X Deluxe rev 2), so I know the speakers are hooked up correctly. Control Panel says no audio device is installed. I have no idea why the hell the onboard 5.1 audio would not work. Finally, the processor is supposed to be an Athlon XP 2500+ running at 1.83 GHz, but under the My Computer -> Properties screen, it is shown as a 1900+ running at 1.46 GHz. I know I didn't format the hard drive properly, but what would cause the audio issue, and how does one get back into the BIOS if one has possibly gotten a little crazy trying to overclock the machine?
