Hoping someone can help. I am running Windows 10 and it randomly crashes out to a blue screen. No error codes, just “SYSTEM SERVICE EXCEPTION”. It’s been happening a while now so difficult to think of anything that changed at the time. But the hardware (apart from a couple of fans) has remained unchanged for years.



Initially I thought it may be because 2 of the fans had apparently failed, and I hadn’t known, but replacing them has changed nothing.



I have tried some suggestions from the Internet such as SFC and DISM. On one occasion one of them found problems and fixed them, but the crash issue remains.



I am presently at my girlfriend’s house and brought the PC over with me to monitor what was happening. Initially it looked as if the issue had gone as it went days running ok, and I wondered if it was because it is not connected to the Internet here; but it has now crashed out twice over the last 2 days.



I assume it may be a driver but have no idea how to identify the cause. And the logs are all very interesting but mean nothing to me.

Having just looked at you're 'read me first' I'll try to provide the requested stuff, but the working desktop being upstairs and the one with issues having no Interconnect connection and being downstairs, makes things rather difficult. I'll see what I can do.



Any help greatly appreciated. Thanks.
 
Good morning @Slytod :)

First let's get some information about your system.

What version of Windows 10 are you running?
What are your hardware specs?

Please download the Sysnative BSOD Dump + System File Collection App - save to Documents folder. Please note that no personal information is collected using this process

Run the app - Double-click on the downloaded EXE file
Output = new folder created in Documents + a zipped version -- SysnativeFileCollectionApp folder + SysnativeFileCollectionApp.zip.

Please note that the app averages ~3 minutes to run on most systems; other systems - it my take as long as 10-15 minutes to run. Please be patient.

Also note: The app auto-zips the SysnativeFileCollectionApp output folder. It is located in your Documents folder.
Windows Explorer should open and highlight the zipped folder

Please attach the SysnativeFileCollectionApp.zip to your post and await further instructions :)
 
Thanks for responding. After much up and down stairs with USB drives etc. I have the following:

Edition Windows 10 Pro
Version 21H1
OS build 19043.1288
Experience 120.2212.3920.0

Ah... a problem. "The uploaded file is too large for the server to process"
I think you need a better server ;)
 
Yes the situation hasn't changed, but so far the BSOD hasn't appeared for a few days. I've no doubt it will sometime though. It's late, will have to post again in the morning.
 
Well I have some bad news for you Slytod.

I analyed your most recent dump file and it doesn't look good:

Code:
SYMBOL_NAME:  PAGE_NOT_ZERO

MODULE_NAME: hardware

IMAGE_NAME:  hardware_ram

STACK_COMMAND:  .cxr 0xffff81012baf0920 ; kb

FAILURE_BUCKET_ID:  PAGE_NOT_ZERO_0x3B_c0000005

OS_VERSION:  10.0.19041.1

BUILDLAB_STR:  vb_release

OSPLATFORM_TYPE:  x64

OSNAME:  Windows 10

FAILURE_ID_HASH:  {e53488a4-f53d-5828-4e8b-03e3e9cba4c2}

Followup:     MachineOwner

 *** Memory manager detected 3 instance(s) of page corruption, target is likely to have memory corruption.

This points to faulty RAM. Not always, but this particular crash was caused by a hardware fault.
 
Ok, thanks. More pricey than a free driver, but I can reseat RAM, and replace if a particular board can be identified. Have you suggestions on the best, free way of testing RAM ?
 
While in there reseating the RAM do the data and power cables maker that they did not come loose.

Depending on how may passes you run Memtester it may not find anything.

How many sticks of ram do you have in the system?

You could test each one in each one of the slots one at a time and see how the system runs.
 
Is Memtest 86 what you refer to ? I've downloaded that but looks like I need to find an unused USB drive to install it on.

All 6 banks of RAM are filled.

Will removing 5 banks st a time, cause issues ? Actually, IIRC I think they need to be installed in pairs.
 
Not tried it yet. The manual is at my place so I'll have to find one on the net.
Will update when I have something to report. (May try a test with all in first.)

Dash it ! Have now twice installed memtest on my USB drive and tried to boot from it. Both times I get a screenful of info come up, limited time to read it before it tries to reboot, then a blank screen. Disheartened.

Actually the data is PC info. Lots of items on PCI or PCIE. And info on ATA(PI) Devices. Nothing clearly interesting.

Given no suggestions as to why I'd just get a blank screen and not indication of a memory test I'll try re-downloading the programme again and reinstalling it on the USB drive. Not sure I'm that hopeful though.

BTW does anyone know why Microsoft Defender, when asked to scan a single file, opens up a window insisting one selects a whole directory. *without* showing all the files in the directory (and then takes so long scaning the whole directory that one gives up and takes the downloaded file to another PC which isn't relying on Defender) ?

edit
Downloaded the programme again; once more wrote the image to the USB drive; exactly the same thing when run. Info on the PC followed by a blank screen.

Found a different programme named memtest (no 86) which is meant to run from within Windows. Doesn't sound quite as effective in that case. Tried it and it says it can only look at part of the memory unless one buys the pro version. Would have liked to have tried it but the box where one specifies which memory to test dislikes anything I type into it; the manual for it is on the upstairs desktop, the one I'm testing is downstairs. Not sorted that yet but already disillusioned.

Any alternative memory checking software folk could recommend ?

As update. It appears that the memtest86 instructions seem not to create a bootable USB drive. Tried many times in different ways. Lastly by actually changing the BIOS to make the removable drive 1st boot priority. Just sails past in that case, into Windows on the C: drive.

It seems as if memtest86 has forsaken BIOS for some other thing. Had to get an old version 4 memtest86 before it would boot. One would have thought they'd keep it backwardly compatible with the older PCs that are more likely to develop an issue and so need to run memtest86 in the first place.

0062fcfcd98 - 25340.9MB

Lowest & highest error addresses. Now need to work out which memory board these are.
