    Im using a USB powered MIDI controller and when I try to use it my PC
    freezes. I only have a 340 watt power supply and am powering the midi
    device through USB.

    Can my power supply be causing the freezes? Im thinking when the
    power is being sucked through USB my power supply might not be
    handling that very well.... my C: drive died last night from freezes,
    would the power supply getting spike be able to kill a hard drive?


    thanks

    The USB port only supplies 5 volts and around 100-500ma for each
    device.

    look in your device manager and at your USB devices, it will tell you
    what it's supplying your device (in ma).
