Random BSOD 7f

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.

Code:

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

Code:

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.

Code:

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

It's pretty old and needs updating.

Code:

2: kd> lmvm atikmdag
start             end                 module name
fffff880`04a8b000 fffff880`050c2000   atikmdag T (no symbols)           
    Loaded symbol image file: atikmdag.sys
    Image path: \SystemRoot\system32\DRIVERS\atikmdag.sys
    Image name: atikmdag.sys

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.

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.

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

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

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.

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?
