    I have 2 70 GB WD Raptor drives. XP does not boot up upon when I have both
    disks connected to the SATA connections. I'm using the grey non-raid ATA
    connections not the red raid ATA connections. The BIOS recognizes both
    drives, but usually the screen just goes blank. When I remove the ATA
    connection on the mobo for the secondary drive, I have better success, but
    at least half the time the same issue occurrs. I have tried moving the
    secondary drive to the 3rd connection as opposed to the second, but still
    the screen just goes blank after enumerating the IRQs.

    I first started noticing problems when the OS clock was off. It's set to
    update through the Internet, but it's like the whole timing was off on the
    machine. For example, looking at perfmon, nothing would display until I
    manually clicked refresh but then it would just remain frozen after updating
    the values. Leaving the computer on and returning after work, the clock
    would be off again....still set to the time I automatically updated it to.
    Additionally, trying to run the ASUS update from the secondary drive would
    also fail as well as trying to install the downloaded chipset drivers.

    Additionally, I seem to have better success with the computer laying down
    sideways than when it is standing up. I have no idea what is going on at
    this point, but I would really love to get my machine running as it was. Is
    it the motherboard? Is it the hard drives...power to the hard drives?
    Problems began around installation of 1004 bios, but I'm not sure it's
    related to that because I was noticing errors with the Sound application
    that comes with the audio drivers just before that as well.

    Any insights would greatly be appreciated. Thanks so much.

    Try a lighter heatsink/fan ? The copper one is kinda heavy.

    High tech circuit boards don't like to be flexed. Maybe
    a connection in the board is broken, due to the board
    getting bent in transit ? When pushing components into
    the board, the board should always be supported underneath,
    to prevent excessive flexure.

    An RMA under warranty should take care of this problem.

    You could also check underneath the motherboard, for any
    brass standoffs that don't line up with plated holes in
    the motherboard. You don't want a standoff touching any
    copper tracks, such as happens if a standoff is not
    installed underneath a mounting hole. Your problem sounds
    a lot like the symptoms of an extra standoff (symptoms
    change when computer is sitting on its side, than when

    Well, that analysis seems pretty spot on. I intentionally did not screw in
    several holes on the mobo as doing so would have caused it to bend. The
    metal plate that attaches to the mobo has 1 cm high ridge along the side
    where the peripherals attach that gets in the way and prevents the screw
    holes from lining up properly. Time to get a new case.

    Thank you again for your always excellent advice.
