    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,

    0x139 Bug check BSOD happening a lot.

    i only know from bluescreenview that the bsods were caused by ntoskrnl.exe and sometimes random drivers.

    heres the link to the skydrive containing the 32 minidumps: OneDrive

  3. Help analyze frequent BSOD, please

    Experiencing frequent BSODs (Memory_Management mostly). Fixed one culprit (Intel SmartConnect driver) but can't find what else is causing NTOSKRNL.EXE to crash.

    Per your instructs, an archive of the Minidump, sys specs, etc follows.

    Several of the dumps point to snapman.sys.
    Code: BugCheck 1E, {ffffffffc0000046, fffff8021bc0ed48, 1, 2} *** WARNING: Unable to verify timestamp for snapman.sys *** ERROR: Module load completed but symbols could not be loaded for snapman.sys Probably caused by : snapman.sys ( snapman+1cf09 )[/quote] Driver Description: Acronis True Image Snapshot Manager driver also included in Seagate DiscWizardDriver Update Site: Support: Service client et support

    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.*chuckle

    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.

    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.
    Code: BugCheck D1, {ffffd57e6e274000, 7, 1, fffff8076dba390c} *** WARNING: Unable to verify timestamp for ahcix64s.sys *** ERROR: Module load completed but symbols could not be loaded for ahcix64s.sys Probably caused by : ahcix64s.sys ( ahcix64s+3390c )[/quote] Driver Description: AMD AHCI Compatible 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,

    Yup, all the latest du8mps are the same ahcix64s.sys error.
    Code: BugCheck D1, {ffffc2fe50274000, 7, 1, fffff80d373a390c} *** WARNING: Unable to verify timestamp for ahcix64s.sys *** ERROR: Module load completed but symbols could not be loaded for ahcix64s.sys[/quote] Mixed memory can sometimes cause weird problems like this. As a test, remove the 1GB DIMM and make sure the two remaining are in the blue sockets per this note from the Users Manual:
    Code: NOTE: Install the memory modules into the blue sockets first, starting with the largest capacity module placed in the socket closest to the processor on the motherboard.[/quote] Are you overclocking your system at all? If yes, reset everything to default and test.

    Other than that all I can suggest is to remove the current SATA controller drivers and use the Microsoft default. See this post for how: iaStorA.sys causing BSOD - Windows 10 Forums
    Ztruker, May 16, 2017
  14. PCGuy53 Win User
    I forgot to mention that the system is not overclocked.

    I checked the memory, and of course, HP didn't put the two 4 gig ram sticks in the blue slots. In order to swap the ram and remove the 1 gig stick, I had to remove my video adapter.

    I must have bumped one of the drive SATA cables, because when I tried to restart, BIOS said the RAID array was critical, and had lost one of the drives. I reseated the cables and did a quick BIOS check on both drives & they were ok.
    The RAID array was still critical, but from my limited past experience, I knew that the rebuild would need to be done in Windows.
    I then got an unumountable boot volume error. When trying to get to Windows repair multiple times, the USB keyboard & mouse were not detected. Tried different keyboard & ports, along with a USB Windows repair drive. No luck. I was able to boot to a third party USB drive ok. This showed 2 single drives instead of 1 RAID array.

    After much weeping, wailing, and knashing of teeth, I got the system booted. Because I had tried several versions of AMD RAIDXpert, it took a while to get back to the RAIDXpert web interface. I am currently rebuilding the RAID array. It's at 5% after 5 hours, so this is going to take a while.

    Hopefully the system won't crash during the rebuild.

    If I decide to get rid of the AMD RAID controller software, will there be a way with the Microsoft drivers to rebuild the RAID array if needed?

    I know nothing about RAID. Never used it and don't see any reason to do so now, sorry.

    Curious, why are you using RAID? What advantages does it give you?
