    Hi all,

    I have been trying to troubleshoot for the past few hours but to no avail.
    It's a fairly new machine (less than 1 yr old), and it was working perfectly until last night. Any help is greatly appreciated.

    System:
    - Windows 8.1, updated few weeks ago

    THE PROBLEM:
    - Big red "X" over the speaker icon. No sound. "No Audio Output Device Installed"
    - Network (Ethernet) component disappeared. When I plug in the network cable, nothing happens. (wireless works fine)
    - Power on takes a few tries, including removing + re-inserting the battery for machine to boot up after pressing the power button.

    TRIED:
    - uninstall, re-installed audio drivers
    - Reinstall Network driver, but got the message "The Realtek Network Controller was not found. If Deep Sleep Mode is enabled Please Plug the Cable"
    - Restored computer to a few days ago prior to the problems
    - Started in Safe Mode

    Everything else is functioning as normal.

    I am wondering if this is a hardware problem or a driver/bios issue. Your input is greatly appreciated.

    JT

    Sounds serious. Either the bios is corrupted, or your south bridge is failing. I would give windows a re install just to rule out windows being fubard, but when your boot up time is effected and your audio and network are both on the frits, that points to a motherboard problem.
