    The crash dump does indeed show that L1C63x64.sys driver could be the culprit.

    There is a newer version on the motherboard website so please try updating to ver 2.1.0.21.
    Code:
    Probably caused by : L1C63x64.sys ( L1C63x64!DmaFillTpds+177 )

    Sorry to ask, but by saying that you mean to update my motherboard or my ethernet drivers?

    Cause i cant find a version 2.1.0.21 of my mother board on their website :

    GA-Z77-DS3H (rev. 1.0) | Motherboard - GIGABYTE Global


    Also googling i found atheros ethernet driver v 2.1.0.27 :

    Download Qualcomm Atheros network driver 2.1.0.27 for AR8151 and Windows 10

    If its this driver, how to install it, since it have those files inside :

    Thanks for your time! really appreciated

    Edit: Also found version 2.1.0.17 if its better on this site , and forgot to say, on atheros website they dont let me download drivers :S

    I did mean the driver version which you will find on the support page for your motherboard. It is always best to use the motherboard manufacturer provided drivers when possible unless they have stopped supporting them.

    Just try that file instead - it may work.

    I have the same Qualcomm Atheros AR8161 Ethernet Card, the drivers come from Windows updates, ver 2.1.0.21 is what is says for mine. The Laptop manufacturer no longer supplies drivers. That is a Windows 8.1 64 bit driver same is used for Windows 10.
    Qualcomm Atheros AR8161.

    It is in the MS update catalogue, so are versions 2.1.0.13 and 2.1.0.7

    It is also listed in that Gigabyte MOBO downloads of Drivers 2.1.0.21

    So just going to the Device Manager and update driver should do, if not uninstall scan for new hardware etc. Should be automatic.

    Or install the one given by Gigabyte for Windows 8.1, your picture shows it (Atheros LAN driver)...Click on "Europe" to download it.

    I notice Gigabyte also supply a "LAN Optimizer", my instinct would be to uninstall that. Again available under Utilities if you want to put it back.
