    AN OPERATING SYSTEM WASNOT FOUND ON MY DELL OTPTIPLEX 755


    I was rebooting my computer and it crashed during the reboot. It now says that it cannot find an operating system, wasn't found. Try disconnecting any drive that don't contain an operating system. Press any key to restart. Any key to restart does not work either, can only start or turn off from the power button.

    :)

    Realtek on a dell optiplex 755

    Is there any way to get realtek or something similar on a dell optiplex 755? The model number is: DCSM. I'm mostly looking to add the enhancements tab in the microphone properties window.
