Solved Random BSOD 7f

[blackshade]

Hello everyone,

Thank you so much for taking a moment to read this post. I'm kind of at my wits end here and have come to the end of my own ability to troubleshoot my issue.

I have just gotten this computer and started the usual plethora of installations and upgrades. Not long into the process, I found I began getting BSOD's, all very random and without warning. I even got one attempting to register for this forum to post this.

I've attached the dump files and hope having a look at them will help someone point me in the right direction to solve this.

Any help will be unbelievably appreciated. Thanks again.

Welcome to 7F.

All of the attached dumps are flagging the same two things, steps to solve these issues are outlined below.

1: Firstly is Intel Rapid Storage driver.

fffff880`09bdd008  fffff880`02ec01cbUnable to load image \SystemRoot\System32\Drivers\dump_iaStor.sys, Win32 error 0n2
[COLOR=Red][B]*** WARNING: Unable to verify timestamp for dump_iaStor.sys
*** ERROR: Module load completed but symbols could not be loaded for dump_iaStor.sys[/B][/COLOR]
 dump_iaStor+0x471cb

If you are not running a RAID setup, uninstall Intel Rapid Storage. First uninstall it from Control Panel > Programs and Features. This one ....

Start Menu\Programs\Intel® Matrix Storage Manager

Then Uninstall the driver from device manager.

1. Right click on "My Computer" icon and click "Manage" on the context menu.
2. It will open the "Computer Management" window.
3. Select "Device Manager" in the left pane, It will list all the existing devices up.
4. Expand "IDE ATA/ATAPI controllers" by clicking on the triangle in front of it.
5. Select one Intel device item under it, right click, uninstall.
6. Continue the process for all Intel items under "IDE ATA/ATAPI controllers"
7. Now restart the computer. At restart, Windows will auto configure the appropriate native system driver.

2: Secondly your ATI graphics driver has been flagged.

fffff880`09bdd4c8  fffff880`04aa91feUnable to load image \SystemRoot\system32\DRIVERS\atikmdag.sys, Win32 error 0n2
[B][COLOR=Red]*** WARNING: Unable to verify timestamp for atikmdag.sys
*** ERROR: Module load completed but symbols could not be loaded for atikmdag.sys[/COLOR][/B]
 atikmdag+0x1e1fe

It's pretty old and needs updating.

Download the 13.9 driver from here then use AMD Uninstall Utility to remove all traces of your current driver, CCC etc. Reboot and install the 13.9 driver.

   Note

When installing choose 'Advanced' or 'Custom' (whichever option is available, just not Express) and uncheck everything except the video driver.

3: Lastly I notice you have AVG and Comodo installed, this may be causing a conflict even though nothing is showing in the dumps. My advice would be to remove both programs and Install MS Security Essentials and MalwareBytes.

   Note

Make sure you uncheck the 'Enable Free Trial' box when installing.

Please carry out the above steps and report back.

Just a quick update.

I made all suggested changes (barring the last, because as my preferred setup, I'd hate to have to change these two) and so far, knock wood, no BSOD's. Should one occur, I will, of course, follow the original advice given and swap out my AV and FW for those suggested before returning for help.

I want to give many, many thanks to Boozad for the time and attention you gave me in this issue, it is greatly appreciated.

Assuming there are no other problems in the next 24hrs, I'll mark this thread solved.

Thanks again.

 

[Boozad]

Thanks for getting back to us, hopefully your BSODs are cured. If any more do occur please run the tool again and post new logs to be analysed to pinpoint the problem. It is a well known fact for BSOD analysts that virtually every AV program can cause BSODs, the only one we've never seen cause a BSOD is MSE hence the recommendation.
All of this may be irrelevant though as like I stated in my previous post there was nothing in your logs pointing to either AVG or Comodo as being a cause of your problems. It was just an observation on my part and may well be nothing to be concerned about.

Do let us know, and hopefully all is sorted for you.

 

[blackshade]

Looks as though all is well on the BSOD front. Thanks again for the help, Boozad. I'll mark the thread as solved.

 

[Boozad]

Great news. If you ever get any more problems don't hesitate to let us know.

 

[blackshade]

Spoke too soon, I guess. Was just watching a YT video when down it went. Sigh.

Well, I've run the tool again and attached the logs. Would you be kind enough to have a look and see what's happened? Thank you so much.

 

[Boozad]

Right, we have different animal here in a STOP 0x7F. This can be down to a multitude of issues and I'd like to rule out RAM first of all.

Download and run MemTest86+ to test your RAM.

   Note

View attachment 333915

Run MemTest86+ for at least 8 passes. This is a long test, ideally set it off before you go to bed and leave it overnight, we're looking for zero errors here. A single error will show something's going bad with your RAM and you can stop the test if it hasn't already completed.

 

[blackshade]

Thanks for the suggestion, Boozad.

Ran it. 8 passes, no errors. I suppose that should make me feel good, but if there's nothing happening with the RAM, this could be a MB issue, couldn't it? I certainly hope not.

 

[Boozad]

OK. Just to confirm, this is a laptop we're working on here correct? And there is no overclocking applied to any of the components at all?

 

[blackshade]

Yep. To both questions.

 

[Boozad]

What I'm going to do is ask the other BSOD guys to take a look at your latest dump to see if anything stands out to them that I'm missing. I'm pretty certain this is a hardware fault and would have hung my hat on it being RAM, I'll just double check that you definitely ran MemTest86+ for 8 complete passes? I'm not questioning your computer literacy here either mate, it's just that some people do get confused and don't actually run it for 8 passes and it's pretty crucial to the results.

I'll give the other guys the heads up to come and take a look, more heads will definitely be better than one in this case I think.

 

[blackshade]

Oh, no worries. I'm not offended at all.

I definitely ran it for 8 passes. 9 in fact, just to be sure. No errors.

I truly appreciate the help and hope to find a solution, because not being able to use my laptop fully is becoming obnoxious. I just got the thing.

 

[Boozad]

I'm going to post to the BSOD team now to come and take a look. It is still possible that your AV suite/s are causing this, would you definitely be averse to uninstalling your current ones and running MSE and MalwareBytes just for testing purposes?

 

[blackshade]

Oh, no. As I said previously, if that's the best course of action, I'm absolutely willing. Say the word and they're gone.

 

[Boozad]

I'd be very tempted to rule them out but let's see what the other guys have to say first.

Hi blackshade .

This bug check code is usually a hardware issue, considering you have tested the RAM
it is probably not the issue (although memtest is not perfect and can give a clean bill of health
to faulting RAM sometimes).

UNEXPECTED_KERNEL_MODE_TRAP (7f)

Arguments:
Arg1: 00000000000000[COLOR=Blue][B]10[/B][/COLOR],[COLOR=Blue][B] EXCEPTION_NPX_ERROR[/B][/COLOR]
Arg2: 0000000080050031
Arg3: 00000000000006f8
Arg4: 00000000500221ba

NPX = Numeric Processor Extension

What should concern us with this bugcheck is Arg 1, which in this case equals to 10 across
all of the uploaded dumps. That being consistent leads me to believe there's something wrong
with the CPU (you already have the latest BIOS offered by gateway),
looking at the failure bucket hints at it as well.

FAILURE_ID_HASH_STRING:  km:x64_0x7f_10_nt!ki[COLOR=Red][B]floatingerrorfault[/B][/COLOR]+16a

// With spaces | [COLOR=Red][B]floating [/B][/COLOR](point)[COLOR=Red][B] error fault[/B][/COLOR]

How hot does the CPU get?

:ar: Test for thermals and stability:

• Download HWinfo and post a Screenshot of the sensors window,
• one at idle and another while putting load on the PC using Prime95 for the CPU side
• Furmark for the GPU.
  • Before running Prime95 make sure to enable Round-off checking (see 1st post under the tutorial).
     Note

  It is not mandatory to run both tests simultaneously, although possible as long as the temperatures are under constant monitoring.

 

[blackshade]

Well that's done.

Here are the screens you asked for, YoYo155. Thanks very much for the help with this, btw. It is appreciated.

Let me know what I should do next.

 

[blackshade]

While I wait for further instruction, and because Boozad suggested it, I uninstalled AVG and installed MSE and Malwarebytes. Not sure if it will make a difference, but it's certainly worth a shot.

Just wanted to update the thread.

Still crashing every time I attempt to watch a video.
