BSOD On Startup error 0x0000001a

LarryB · 27 Sep 2015

Hi Axe0,

Just to let you know MemTest86+ completed 9 tests successfully with no errors
I got around to completing the 5 tests available on Seagate Tools and they also passed with no issues
Chkdsk completed successfully and no errors found after a restart

As for AVG, Using the uninstall tools on their site, I still found references to AVG in the user profile \appdata directory, and also in the user registry. Those folders were deleted so as far as I am concerned AVG is compltely stripped from this laptop

So, after all of the tests no further blue screens occurred. The laptop was left powered off a number of times over the weekend and there were no blue screens on startup

The only significant change that was made was the BIOS upgrade. However as mentioned before these BSOD´s usually occur if the laptop is left off or cold for a few days. So lets see how it goes and I´ll report back next week

Thanks again for the help and pointers in diagnosing problems. I´ll keep these tools and your suggestions handy.

Cheers

Hi Axe0

Unfortunately I am back to square 1. The laptop was off for a few days and on startup last night immediate black screen followed by a restart. This was over and over until it got that little but further past the Windows splash screen and managed to capture two blue screens, one a memory management

In spite of the tests performed at the weekend I am targetting tha hard disk and memory for replacement. I have a spare hard disk here in work, I think a solid state, and I will rebuild the machine and test. If that fails I´ll purchase memory

If you have thime would you mind reviewing the latest dump files and logs that I collected ' see attached zip in opening thread.

It is odd however that this issue comes about if the laptop is off for a few days. After 1 hour or so working in safe mode with networking the laptop can be restarted and loads in normal mode with no crashes.

Could it be a possible mboard issue rather then the HDD or memory? Hopefully it is one of those three, or else I will just tell my partner that she has magnets in her fingertips and they are causing havoc with her laptop!!!

Cheers

Please use the tool again and upload the zip file.
I can take a look at the dump files, but I prefer to have updated information about your system in case of anything I miss or could be wrong about because of changes to the system.

Please remove Avast using the uninstall instructions and use Microsoft Security Essentials for now.

Code:

*** WARNING: Unable to verify timestamp for aswSP.sys
*** ERROR: Module load completed but symbols could not be loaded for aswSP.sys

Removing Avast now, and will install Essentials. Will leave the laptop cold for a few days and power it up at the weekend and see what happens

Quite odd. That is two free but recommended AV´s now that flagged with errors on the laptop

That indeed is really odd, my guess is either some driver is not mentioned but messing or you have hardware / dust problems. I would doubt dust, but cannot rule it out yet.

To rule out drivers

Diagnostic Test

DRIVER VERIFIER

Warning

Please make a backup of your important files and get your rescue media or create one.
Please create a restore point.

Please follow this tutorial to run driver verifier.

Some windows drivers are blamed in a few crashes, but that usually means that a 3rd party driver is actually the cause.
Driver verifier stresses your drivers and will crash your pc if any driver fails due to a violation.

Driver verifier should be performed for a max of 48 hours, or when you have a bluescreen, whatever comes first.

If driver verifier has found a violation and you can't get back into windows normally, try to boot into safe mode and reset in safe mode driver verifier, or in the troubleshooting options open command prompt and type verifier /reset.

Note

Your system will act very sluggishly while driver verifier is enabled, this is normal as your drivers will be being subjected to heavy testing in order to make them crash.

Avast Removed using uninstall instructions. Upon restart of the PC it blue screened immediately. Essentials not on here yet and I am working in safe mode.

Latest log file and dump file collected and attached in opening thread

Just saw your other post. I cleaned out the laptop with air compression a while back but I´ll do it again. I like dismantalling laptops. But I always end up with a screw that I forgot to put in!!!!

Cool. I´ll give it a go but I´ll need to keep this PC in safe mode for a bit and I should be able to get into normal mode to kick off the driver verifier
