Please help me find the source of these bluescreens

Hey guys,

I'm wondering if you would be able to pinpoint the cause of these bluescreens. It is a customers machine, and he says it does it 'most of the time', but that its still intermittent. It did not happen in the 3-4 times i have turned the machine on however.

I rant MemTest 4.10 for 1 1/2 passes and it did not find any errors.

Any help would be much appreciated, cheers

Try testing your hard disk and file system for errors.

chkdsk at the command prompt and the manufacturer's hard disk util.

Also open machine up and remove memory.  Wipe RAM clean with a dry cloth or paper towel.  Blow out memory slots and reinsert memory.

Well that'll keep the machine busy for the next couple of hours :P

Running CHKDSK, SFC /SCANNOW and the Samsung Diagnostics Utility (Its a samsung drive).

SFC found errors which it said it could not fix, is this something i should be looking into? I did take a look at the CBS.log but im not quite sure how to decipher it.

Post it up here for experts to look at.

Could be file corruption, disk error, malware.

I would re-run chkdsk with the /F and /R options to repair disk errors.  So it would be "chkdsk /F /R". In Windows 7 you'll have to run this as administrator.   To run it click "Start->All Programs->Accessories" then right click "Command Prompt" and select "Run as administrator".  Simply type Y to accept.  And the reboot so it can check the disk.  Below is what it looks like when run:
C:\Windows\system32>chkdsk /F /R
The type of the file system is NTFS.
Cannot lock current drive.

Chkdsk cannot run because the volume is in use by another
process.  Would you like to schedule this volume to be
checked the next time the system restarts? (Y/N) Y

CHKDSK /R assumes the /F command so there is no need to use both :)

And its currently running at the moment, I'll post the CBS.log up here as soon as its finished. Then while you guys peruse that, I'll run the Samsung Utility.

Cheers for all the help so far :)

Here is the CBS folder, there are a lot more files in there than what i normally see, so i decided to upload the whole folder. He did mention that sometimes his windows updates wouldn't work either and there is a file in there that i believe is related to that.

CHKDSK did not find any errors. Will run the Samsung utility now.

Thanks again for your continued support.

EDIT: will not let me upload the .cab files included in the folder (even when zipped) so I have just uploaded the CBS.log

There's nothing in the logs about Failed repairs.

There are lots of Failed uploads of reports but they might be blocked by firewall or something.

There are lots of Failed package installs of updates and verification of software packages.

So he is getting corrupt files happening.

These are the files about the failed repairs.

As it is i have not been able to fault this computer yet. I have had no issues with it whatsoever.

Do a search on NAPHLPR.DLL and NAPCRYPT.DLL and see if they are in this system.

It seems those two files may be missing from the machine.

Ok there are 4 of each of those files dbrunton, in winsxs/amd64, winsxs/x86, system32 and sysWOW64

OK.  So at some stage the system updated itself and put the files in correct place.

Samsung utility didn't find anything?
And have you tried Windows update on this machine?

800B0001 error when checking for updates, running the windows 7 system update readiness tool now as apparently that can fix most Windows Update problems.

And the Samsung utility didn't find anything

This fix fixed the windows update issue :)

i ran the Microsoft Fixit - http://go.microsoft.com/?linkid=9665683 
After that i could run the system update readiness tool
then finally i could search for and download updates :)

Any chance that this could also be related to the bluescreening?

Who knows?

Memory and disk test OK.  sfc should be OK now.  Windows update is OK now.

Do some brief browsing on safe sites to check that IE works OK.

You could clean out all his temporary files (check with owner first) and then let it defrag itself.  If it passes that send it back and keep fingers crossed.
