    Frequent & random BSOD ahcix64s.sys & ntoskrnl.exe

    I retired several years ago from 20+ years as a computer tech for a large non-profit in midwest USA. Reading error logs is not one of my strong points. I am having repeated BSODs on my own computer for quite a while that I have not been able to resolve.

    My DM Log Collector file is attached.

    Sometimes it will run for extended periods of time without problems, while other times, it will blue screen on me soon after booting. I have had problems with the system hanging for 30 seconds or more, but that is probably something for another post.

    Here are some of the things I have tried. There may be other things I have done, but did not document.
    1. The 9 Gig memory is the original factory memory that HP installed. I ran Memtest 86+ for a day or two with no errors.
    2. I have 2 WDC WD2001FASS-00W2B0 hard drives in a RAID 1 configuration. Western Digital Data Lifeguard & other drive tests have showed no errors.
    3. Some of the things I have tried recently with no permanent success: Unselected AMD RAIDXpert Service in msconfig.
    Uninstalled storage controller driver for AMD AHCI Compatible RAID Controller. ( That caused an Inaccessible boot device error for a few boots, but got that fixed.
    Let Windows reinstall the RAID controller driver.
    Tried several versions of the driver that Windows listed when trying to manually select the driver.
    Downloaded RAIDXpert v3.2.1540 from AMD & installed. Device Manager now shows AMD AHCI Compatible Controller v (12-11-2012).

    None of these things have fixed the random BSOD problems. I am hesitating in "nuking & repaving" my PC, because I have some programs that I have installed (legally) from Giveaway of the Day - free licensed software daily that I would not be able to reinstall.

    Thanks for your help,

    Several of the dumps point to snapman.sys.

    The one you have is very old: Timestamp: Fri Jul 13 06:03:12 2007

    Uninstall Snapshot manager. If you still need it, get the latest version available. There are probably free alternatives available.

    YOu could probably replace it with Macrium Reflect Free or Pro (Pro is what I use, gave up on Acronis many years ago).

    Thanks for the info. After I made my post, I decided to review Tenforum's WinDBG tutorials. I had a v8.1 of WinDBG, so I uninstalled it and installed the Windows 10 version. I saw the references to snapman.sys in my dmp file. I forgot that I had Acronis True Image Home installed, and don't use it. I will uninstall it and see if that helps.

    I saw this link about Acronis 'leftovers' when uninstalling. Do you think I should worry about that, or just wait & see what happens? Beware of Acronis Issues | Wilders Security Forums

    Depending on how much I use the computer this week, it may be a while before I find out if the BSOD problems are resolved.

    I use Revo Uninstaller (I have the Pro version) just because of issues like these left over files. You could try the portable version. It doesn't have to be installed, you can just run it.

    In all likelihood, the left over files would not cause you any problem.

    I uninstalled Acronis True Image Home 11 with Revo Uninstaller portable and the most agressive settings, & rebooted. There is still a snapman.sys file in the System32\drivers folder that is dated 7/18/2010.

    The system hasn't crashed since this morning, and I hadn't made any changes until this evening. Go figure.

    Do you see anything else in the dmp files of concern. Many of the errors seem to reference the ahcix64s.sys file. Is it causing problems, or is it just the unlucky file that gets blamed for the error?

    I ran System Explorer & NirSoft DriverView. It showed 3 Acronis drivers still loading.

    tdrpman.sys Acronis Try&Decide and Restore Points Volume Filter Driver, Acronis Acronis Try&Decide and Restore Points C:\WINDOWS\system32\DRIVERS\tdrpman.sys

    tifsfilt.sys Installable Driver Acronis True Image File System Filter Acronis Acronis True Image C:\WINDOWS\system32\DRIVERS\tifsfilt.sys

    timntr.sys Installable Driver Acronis True Image Backup Archive Explorer Acronis Acronis True Image C:\WINDOWS\system32\DRIVERS\timntr.sys

    I ran 2 Acronis cleanup tools. Twice, rebooting after running each once.
    Acronis Backup & Recovery 11 Cleanup Utility | Knowledge Base
    Acronis True Image: Cleanup Utility | Knowledge Base

    Running the cleanup utilities reduced the leftover registry keys with 'acronis' in them from over 1000 to less than 100. I'll probably leave them alone.

    After that, there was only 1 Acronis file left running, tifsfilt.sys. I used Sysinternals Autoruns to unselect the driver.

    I will run the system for a while to see if I get any more crashes.

    Great work, more complicated than it should be but sounds like you got them.

    Still having BSODs

    Well, I thought my BSODs were gone, but I just had another one, after restarting the system. I have attached a new log file. I might not be able to respond tonight. We are going to to see Garth Brooks in Kansas City.

    The new dump indicates a problem with the AMD raid controller.

    Driver Update Site:

    Are you using a RAID setup? If not, uninstall the AMD AHCI Compatible RAID Controller

    I also see a problem with Avast anti-virus

    Uninstall Avast anti-virus.
    Make sure Windows Defender and Windows Firewall are enabled.
    Run that way for awhile to test, see if that resolves the problem.

    My computer is still crashing with the same ahcix64s.sys error. In response to your last post, I am still using RAIDed drives.

    Avast was uninstalled with Revo Uninstaller Portable.

    I didn't have any luck finding newer drivers from AMD.

    The strange thing is, the drivers.txt file from the DM log collector shows a date for ahcix64s.sys of 4/4/2008 2:56:04 AM, while the ahcix64s.sys file properties and the msinfo32.nfo file show a date of ‎August ‎17, ‎2012, ‏‎8:42:36 AM.

    I found another copy of the ahcix64s.sys file in one of the C:\Windows\System32\DriverStore\FileRepository\ folders (Same file properties as the original). After using a bootable flash drive, I renamed the original, then copied the FileRepository version into the drivers folder. I still get crashes.

    The system has NEVER crashed while in Safe Mode with Networking (That is how I am sending this post.) The latest log collector file was collected while in Safe Mode with Networking. NirSoft DriverView shows that ahcix64s.sys is currently loaded while in Safe Mode.

    A new log file is attached. Thanks for all of your help,
