  1. Hi supporters,

    I think my problem is very similar to this guy's: techspot.com/vb/topic97620.html

    I also do suffer from the Blue Screen of Death.

    Technical information:

    ***STOP: 0x000000D1 (0x00000002, 0x00000002,0x00000000, 0xBGFAD745)

    ***ar5211.sys adress BGFAD745 base at B6F7D000, Datestamp 3f96500b

    what it said^.

    I've heard that it's the wireless card.
    A possible solution is to update the card, but how?

    I tried to follow these steps: support.microsoft.com/kb/927015

    I'm in Safe Mode, but in Network Adapters, I can't see anything named something with Atheros. Only Realtek RTL8139 Family PCI Fast Ethernet NIC and Skyr@cer Pro PCI 154.

    Another thing, how do I make a minidump?
    For as I can see you guys need it to know more about the issue.
    In the folder C:\WINDOWS\Minidump are there no files?

    I will appreciate your help very much!

    How to find your Minidump Files:

    My Computer > C Drive > Windows Folder > Minidump Folder > Minidump Files.

    * Let s know if they are there.

    ar5211.sys is a Arheros wireless driver and is often used in D-Link wireless offerings.

    1. If this is a prebuilt system go to the manufacture's website, find your exact model and update the wireless/ethernet/networking driver from there.

    2. If this was assewmbled by you, a friend, or a local PC shop, or other third party manufactures then find the make and model of your motherboard, go to the manufactre's website, find your exact motherboard and update from there.

    I can't find any documents in that folder.

    The system is prebuilt, but the Skyr@cer-card I installed myself.

    What should I update then?

    Did you have any issues prior to installing said card?

    Update your wireless/ethernet/NIC drivers. See previous post.

    Nope, not really any issues.

    Skyr@cer Pro PCI 154 is the card I want to update, right?

    Atheros = skyr@cer ?

    Yes, since it is a dedicated card installed by you go to their website and see if they have updated drivers.

    But how do I update this driver?

    Safe Mode + network activated ?

    Or download driver from another pc and move the driver via a usb key?

    Sorry, forgot you can't access the internet. Download as you state via a USB key. Keep in mind that if the card is bad, and I said if, no amount of updating can help.

    By the way, can you connect via ethernet cable?

    No, I can't connect via ethernet cable.

    If everything works:
    I've installed the driver in Safe Mode, reboots and run in normal mode, I will not encounter any blue screen?

    Just to be sure, it's the driver file (398 KB) right?

    We can't say at this point because we don't know if your card is functioning properly but the steps you are taking are correct.

    I checked the drivers you linked to. How old is your card/system?

    I guess it's pretty old, but I can't remember the exact age.

    Is it the driver of my Skyr@cer or the chipset (atheros) I have to update?

    Because I found a person who claimed that Skyr@cer Pro PCI 154 used the chipset AR5212 from Atheros and therefore he referred to http://www.station-drivers.com/page/atheros.htm for a chipset update.

    Yes, my Skyr@cer Pro PCI 154 uses the AR5212 chipset.
    Maybe this (https://www.techspot.com/vb/topic39651.html) could be interestering?

    According to http://www.atheros.cz/, I have to download AR500X2 for the note/chipset: AR5112/AR5212.
    And the AR5112 was the note that BSoD used.

    I just downloaded a update for AR5212 at http://www.station-drivers.com/page/atheros.htm from 31/03/2010.
    Maybe this downloaded file is what I need?^^

    The 31/03/2010 version of AR5212 seemed to solve the problem.

    Just started up my pc and there was no BSoD after the installation.

    Nice work on your part. I have to say that I am really suprised they had a driver for your card as old as it is. Usually companies will support for a few years and then move on because that is where the money is.
