Windows 7: Several BSODs following power outage. Varying BCCodes and frequency.

01 Mar 2013   #1

Windows 7 Ultimate SP1 64 bit
Several BSODs following power outage. Varying BCCodes and frequency.

I recently built a pc and hadn't had time to buy a battery backup when the power went out unexpectedly while I was on it. The computer seems to be acting the same way it did when I had to force a shut down a month or so ago. At that time it was the hard drive causing all my BSOD woes. I ran a dsk check and several sfc /scannow passes to resolve the past issues.

This time, however, sfc /scannow can't get past 14% without giving me an error saying that it found errors but could not fix them. The verifyonly version of sfc can get past 14%, but it still hits a point where I get a "Windows Resource Protection can't complete that action". In addition to my hard drive repair tools not working, I get several BSODs that I recognize from my previous trouble with my hdd. Error codes 19, 24, etc. I have also gotten a BCCode a, 1a, and I believe a 3e. I ran a full chkdsk on boot and tried to recover damaged sectors, which took several hours to complete. It seemed to help, but after a day or two the crashes returned, less frequently. I will attach the minidump files and CBS logs to see if anyone with more experience can help me.

As far as symptoms go, the computer is very unstable when it first boots. Usually trying to open Chrome or anything before letting it sit for about 3-4 minutes causes a BSOD. The only extensions I have in Chrome crash from time to time, with crashes always seeming to cluster around each other. Eventually I get the "Aw snap" message and Chrome crashes completely. I have scanned my system with Avast! antivirus several times with no threats popping up. I can go through periods of relative stability where I am able to game and use Skype and other programs normally, but every 1-2 days I hit instability and BSODs.

Here are two of the most recent minidump files:

And here are the CBS logs from the SFC failures:!111

Here is the SF zip folder requested by the BSOD Posting Instructions page. Sorry I didn't have this up from the start.

Got the zip file on here.

Sorry it wasn't up from the start. Any help would be great!

Thanks in advance!

Shameless bump.

If anyone happens to be taking a look at my logs and minidump files I would like to first say thank you, and second I would like to ask you if you wouldn't mind letting me know if you have any solutions/ suggestions in the works for me.

I have resorted to working from my laptop as my rig has blue screened 2-3 more times since the time of this original post. One was a PFN_LIST_CORRUPT which happened out of the blue (no pun intended), and the others were MEMORY MANAGEMENT which seemed to both happen when I was accessing my HDD intensively (scanning with Avast!, trying and retrying SFC, etc...). I will try to get an updated file tacked on here as soon as my desktop is stable long enough for me to generate/ upload one.

Since the SFC and ChkDsk tools did't seem to be getting me anywhere in terms of HDD stability, I have created a bootable disc of Seagate's SeaTools for DOS hard drive test/ repair program. The drive passed 3 short tests, and is currently 30% through a long test. This utility seems to just be Seagate's version of the /chkdsk function built into Windows.

I'm trying anything at this point.

Thanks again,

I will also be running Memtest86+ well into the night to be sure the outage didn't damage my RAM. I have run memtest before, and both sticks came back clean after 3-4 passes in several configurations on the motherboard (tested with the sticks together, and separate, in multiple sockets). I am just going to let both sticks run the test as a pair throughout the night and see what happens when I wake up tomorrow.

What is the situation here? Cannot you boot up the computer normally? If so, boot into safe mode and then follow the Blue Screen of Death (BSOD) Posting Instructions.

We need the information in detail.

I edited the original post to include the diagnostic zip file outlined in the posting guidelines. Attached to this post is an updated I uninstalled SP1 last night, though. I am fairly sure the problem is just corrupt system files. I can't fix that with SFC (since it's broken, as mentioned in the OP), so I'm tempted to just do a repair install.

I ran two 'long' hard drive tests (via SeaTools) last night and the drive passed both of them. I also ran Memtest86+ for 12 hours (about 10 passes) with no errors. This has to be a corrupt driver interfering with my system files or malware preventing SFC from doing its job. I have scanned repeatedly with Avast! (before I uninstalled it), and MSE (after I replaced Avast! with it) and both turned up no infected files.

Any more information would be great. I'm pretty sure I've posted everything mentioned in the BSOD posting guidelines, so I'm not really sure what more information you need.

fffff880`031848a8  fffff880`08e66905Unable to load image \??\C:\Windows\system32\drivers\aswMonFlt.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for aswMonFlt.sys
*** ERROR: Module load completed but symbols could not be loaded for aswMonFlt.sys
Uninstall Avast using Avast Uninstall Utility. Apparently it seems that You have no avast in your system other than this particular driver. Is it right? In case, Go to C:Windows\System32\drivers and there delete that file aswMonFlt.sys. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Download, install and update those, and then run full system scans with both of them, one by one. Scan the system for possible virus infection with these two programs, too. It is needed.
Daemon Tools, Alcohol 120% and Power Archiver Pro uses SCSI Pass Through Direct (SPTD), which is a well known BSOD causer. Uninstall Daemon Tools at first. Then download SPTD standalone installer from, and execute the downloaded file as guided below :
  • Double click to open it.
  • Click this button only:
  • If it is grayed out, as in the picture, there is no more SPTD in your system, and you just close the window.
Report us the situation after doing these. If there are further crashes, post them following the BSOD posting instructions. There might be some more things to troubleshoot for .... but after making it sure that there is no virus and no sptd present.

I went ahead and did a repair install of Windows 7 to make things a bit cleaner during this troubleshooting process. After reinstalling, I downloaded MSE and attempted a full scan. It stopped about halfway through telling me the service responsible for running the program stopped working. It gave me the option to either restart it manually or reboot my computer to restart the service. I chose to restart it manually, but will wait until after further scans with MBAM to resume the MSE scan.

Also, Avast! is no longer present on the system. Same with the C:Windows\System32\drivers\aswMonFlt.sys file. Both were removed by the reinstall.

After installing my motherboard drivers and EVGA graphics drivers I ran into a BSOD while deleting the windows.old file. I have attached the SF diagnostic zip file with the logs of the two crashes that have occurred AFTER my repair install of Windows 7.

I am currently about 30 minutes into the full scan with MBAM. I used the SPTD installer to verify that SPTD is no longer installed on this system (the "uninstall" button was grayed out). I also uninstalled all 3 programs you mentioned that use SPTD. I will run Kaspersky's TDSSKiller as soon as this full scan is completed. After I get this scan done, and the TDSSKiller scan out of the way, I will retry the MSE scan to see if it was a fluke or if something about the way it's scanning the system is forcing a crash.

Thanks for all the help so far,

Just finished the rootkit scan with the TDSSKiller tool, and the MBAM full scan. Both came up totally clean. I am restarting the MSE scan now. Will post back if/when that is done.
