Windows 7: Intermittent BSODs, errors 0x0c2, 0x019, 0x05c, 0x00a

Intermittent BSODs, errors 0x0c2, 0x019, 0x05c, 0x00a


My laptop is around 9 months old, and first showed a few BSODs about 6 months ago. It is still within warranty, and I sent it back to the manufacturer, who apparently did a RAM burn-in or test, found nothing, factory reset it and sent it back. This solved the problem for a few months before it started again, and it has continued for the past month or so. The error codes are in the title in abbreviated form. The BSODs tend to occur when either loading the desktop or launching a program, but they aren't reliably caused by anything and I think they have sometimes happened when doing basic word processing/web surfing etc.
I have run the windows memcheck for a total of 4 passes (2 on standard setting, and 2 on extended) and dskchk at least twice, both with no joy. I updated drivers, and finally the BIOS about a week ago. Since the BIOS update I have had no BSODs, but they are really sporadic (occurring sometimes every day, sometimes once a fortnight), so it's hard to know whether the problem is actually solved.
I tried looking at the minidumps (attached) with BlueScreenView, which shows a problem every time with ntoskrnl.exe, and sometimes fbfmon.sys, fltmgr.sys, hal.dll, and fileinfo.sys additionally, but none of these other files are consistently flagged as problems.
I would really appreciate any help in tracking down the problem as far as possible, as my warranty expires in about 3 months, and if the problem was not fixed by the BIOS update, it would be useful to have some ammunition when I send it back so maybe it will actually get fixed this time. Basically I'd like to know if there is a chance that my BIOS update fixed the problem or not based on what the minidumps show, because I don't have the knowledge to verify this.
The OS listed in my specs is the original one, and I'm not overclocking anything.
Apologies for the mammoth post, but I've tried to be as comprehensive as possible.

Hi and welcome to Seven Forums,

If you are overclocking your system, please return all overclocked components to their stock speeds. If the BSOD's are found not to be caused by the overclock, you can re-overclock the components once we have finished the diagnostics

I have noticed you have 2 anti-virus programs installed, Zone Alarm and AVG. Please correct me if I'm wrong though! Two real time anti-virus programs can cause conflicts so I would recommend uninstalling them both and replacing them with Microsoft Security Essentials. This will offer better protection and is less likely to contribute to a BSOD. If you want on demand malware protection I recommend Malwarebytes' Anti-Malware. How to use Malwarebytes' Anti-Malware to scan and remove malware from your computer.

The BSOD dumps you gave me do not give a definitive cause for your BSOD's. They pointed at ntkrnlmp.exe which is a system file and very unlikely to cause a BSOD.

As a result I recommend you check your hardware for issues. Please run Memtest86+ to check your RAM. Let it run for 6-8 passes overnight as described in the tutorial. Pay particular attention to parts 2 and 3.

Also check your HDD for errors using Seatools and chkdsk.. Download and create a bootable version of the Seatools for DOS program as described here. For check disk, follow this tutorial: Disk Check

If you have any questions, feel free to ask

In addition to the excellent steps Stephen has suggested: Crashes primarily point to hardware. They may be related to your processor, your hard disk (run Stephen's checks for the hard disks and memory), or your motherboard (those are my prime suspects, but it still may be something else entirely). Run some hardware checks.

Hi Stephen and writhziden, thanks very much for your advice.

AVG and ZoneAlarm were an antivirus and firewall respectively. I installed them following someone's advice, but I've uninstalled them and switched to MSE and Windows Firewall, which seem to be a much cleaner and better regarded combo!

I'll run those various tests over the course of the next couple of days and see if anything crops up. I've already run chkdsk (which I called dskchk in the OP, my bad) with no results, but I'll give the Seatools one a try as well.

Replacing zone alarm and AVG with the Windows firewall and MSE is a good move. Run through the tests at your own pace and report back the results.

I've only run Memtest86+ so far, which ran for 11 passes with no errors. I ran chkdsk before with no results as a I said, but when I tried to run Seatools it showed the message "no hard drives found". I read somewhere that you need to configure your hard drive to IDE instead of AHCI, but I don't know what that means or if it's safe to mess about with those settings in BIOS. Any idea why it isn't working?

Also, my computer does not have a discrete GPU, but runs on the integrated Intel hd 3000 graphics that come with the i series CPUs. Should I just run the CPU stress test, or should I run the FurMark GPU test? And are the stress tests likely to invalidate my warranty?



EDIT: I ran the Seatools for Windows tests (long generic, short drive self test, SMART check) instead, all with no errors. Can
I write the HDD off as the culprit now?

I also forgot to ment
ion that I had another BSOD 2 days ago, so the BIOS update didn't fix the problem. I've run the BSOD Dump & System File Collection app again and attached the results (only the most recent dump from 20/06/12 is new).

Just an apologetic bump as this has slipped way down the boards - I would have contacted the members concerned but I can't seem to private message as a new member.

Apologies for the delay. For once a bump has been used in a good way as I'd completely forgotten about this thread! My apologies again.

Ok, your latest dumps are still indicating hardware issues. As you couldn't get seatools for DOS to work, try using chkdsk - follow this tutorial: Disk Check. Just to be sure there are no HDD issues.

Now, I would say to run some stress tests but I recommend not doing so on a laptop as the cooling is not always sufficient to deal with the heat of the CPU and graphics card. So, lets try this:

  • An underlying driver may be incompatible\conflicting with your system. Run Driver Verifier to find any issues. To run Driver Verifier, do the following:
    a. Backup your system and user files
    b. Create a system restore point
    c. If you do not have a Windows 7 DVD, Create a system repair disc
    d. In Windows 7:
    • Click the Start Menu
    • Type verifier in Search programs and files (do not hit enter)
    • Right click verifier and click Run as administrator
    • Put a tick in Create custom settings (for code developers) and click next
    • Put a tick in Select individual settings from a full list and click next
    • Set up the individual settings as in the image and click next
    • Put a tick in Select driver names from a list
    • Put a tick next to all non-Microsoft drivers.
    • Click Finish.
    • Restart your computer.

    If Windows cannot start in normal mode with driver verifier running, start in safe mode. If it cannot start in safe mode or normal mode, restore the system restore point using System Restore OPTION TWO.

    If you are unable to start Windows with all drivers being verified or if the blue screen crashes fail to create .dmp files, run them in groups of 5 or 10 until you find a group that causes blue screen crashes and stores the blue screen .dmp files.
    The idea with Verifier is to cause the system to crash, so do the things you normally do that cause crashes. After you have a few crashes, upload the crash reports for us to take a look and try to find patterns.

    When you are ready to disable Verifier: Start Menu -> All Programs -> Accessories -> Right click Command Prompt -> Run as administrator -> Type the following command and then Enter:
    verifier /reset
    -> Restart your computer.
Thanks to Writhziden for providing the Driver Verifier steps.

Oh, and to contact me in the future if I've forgotten you again (I'll try not to ) you can either send me a Private Message of Visitor Message. Any member should be able to do them. Go to my profile page and click "Send Message" underneath my profile picture. Choose either PM or VM. I prefer PM as I get an email but a VM is absolutely fine.

No worries . I can't see any private messaging options on my CP or when I view your profile, and I read on another thread that new members can't send PMs until they lose their 'new member' status, as a spam-protection measure. Guess I'll just have to post some more...

Chkdsk reported no faults when I ran it. I tried Driver Verifier for about half an hour, doing all the things I usually do like watching video, using a word processor, surfing the web, and playing light games, which produced no crashes. The only abnormality I noticed (aside from the computer running a bit slowly) was that sound lagged occasionally, by which I mean that it slowed down and stuttered. Does that sound like any indication of a driver fault?
