    The WPRO_41_2001.sys driver is on old version of the WinPcap driver, according to Usasma's resource.

    Reference: Driver Reference Table - WPRO_41_2001.sys

    It is a network driver that has the ability to capture all data entering or leaving an adapter. For that reason and being that your adapter driver was crashing, it is the most likely cause of your issues at this time.

    If you did not intentionally install it alongside something like Wireshark, then it is not without reason that a black hat hacker installed it on you. It's unlikely but very reasonable and practical for them to do so.

    So, I would look at your installed software to see what you might have installed that installed that too, then uninstall. It may even show in the uninstall list simply as WinPcap. If you see that, uninstall that directly.

    If you're still stuck on getting rid of it, let me know and we'll take care of it manually.

    Ok, cool, but installing the new WinPcap might not have gotten rid of the old file, which is needed to do.

    You can check at C:\Windows\System32\drivers for the WPRO_41_2001.sys file. If it is still there, it still needs to be uninstalled or removed manually. (Let me know if you need instructions on how to.)

    (The new and "good" WinPcap driver is at the same location with the name of npf.sys.)

    If it is gone, please provide a new crash dump reflecting the current state of the machine.

    -AND-

    Please provide a screenshot of CPU-Z's memory tab and a screenshot for each stick of memory you have of the SPD tab.

    My questions: Why have you not provided your system specs and what is this killer gaming driver/software? I've tired to get on to the Killergaming site and no browser can find anything. So I'm very suspicious of that driver/software.
