Exception code: 0xc0000005 with Fault offset: 0x00000000

Question

_{Tuesday, July 18, 2017 6:11 PM}

I've got a new desktop PC with Windows 10 Home (version 1703) and most things are working perfectly. However, for a few days now several apps of mine have started crashing instantly with nothing obvious happening. On every occasion there is an Error event log showing Exception code: 0xc0000005 and the overwhelming majority also show Fault offset: 0x00000000.

I have no idea what is causing this. Each App has been working fine for months or years with a variety of OS including the current one and are still working on my laptop which has Windows 10 Home edition (version 1607). I have tried uninstalling updates, rolling back drivers, etc, to no avail.

The apps concerned are all game related programs written by myself and use DirectX9.0c/DirectX9Ex. I am doubly baffled because very similar programs of mine work fine as did these till a few days ago.

Does the 0 fault offset mean something specific? Is there something else I can check? Would/could a virus cause this behaviour?

Hi,

What' the "Faulting module" in the event log? Would you please upload the detailed event log of your issue?

When did this issue happened? Some updates or some changes may be done before this issue.

Have you tried to restore the system back to previous point by using System restore to check this issue?

I might suggest to obtain a user mode dump of the crash which has the potential to pinpoint and identify the problematic module.

You can configure Windows to create user-mode dumps. Create a System Restore Point first.

If you copy and paste the following in Notepad and save as a .reg file (save with the .reg extension and give it any name such as dump.reg), then right-click the .reg file and select "Merge" to add to the registry, a .dmp file at the time .exe crashes should be created in the C:\CrashDumps folder:

Please replace *.exe as your own application name.

***Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps\.exe]
"DumpFolder"=hex(2):43,00,3a,00,5c,00,43,00,72,00,61,00,73,00,68,00,44,00,75,\
00,6d,00,70,00,73,00,00,00

After application crashes, can you then make the .dmp file available (provide link) via a public folder on OneDrive (SkyDrive) or similar site?

Here's a couple of links on using OneDrive (SkyDrive):

More info on collecting user-mode dumps:

To stop the creation of the user mode dump files run the following registry file:

Windows Registry Editor Version 5.00

[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps\explorer.exe]

You can delete the C:\CrashDumps folder anytime.
