Windows hardware issue 1001

Question

I got an event ID 1001 and it was in reliability monitor as a windows hardware failure. I checked the dmp file and did the chkdsk, sfc and dism commands, I haven't gotten another crash/event yet. I can't find the original id as I think I might've removed it getting rid of the windows constant reminder id's in event viewer but I have the event reminder in event viewer and I have a memory dmp for it too. Maybe someone can help me find out what the issue is and how to fix it. Thanks.

here is the link to the dmp file. https://1drv.ms/u/c/2a9f1ec803f7b199/IQCiIGtQvesTRpB2916HwRj8AYQ3RNnovCbe3wKjYcANzXE?e=nrwEWp

Answer 1

Hello, thank you for your reply.

I spent some time downloading the file.

The blue screen logs suggest an external drive connection/USB/hard drive enclosure/filter driver caused the exFAT write process to freeze, rather than a genuine blue screen you experienced. chkdsk didn't find the problem, which aligns with this assessment.

First, try different USB ports, cables, and hard drive enclosures.

Then check if the problem only occurs after heavy writes, waking from hibernation, or unplugging/plugging.

Next, check third-party filter drivers such as antivirus, sync drives, encryption, and disk utilities.

Your dump file shows exfat.sys as the culprit.

Per one good summary source - "exfat.sys is a system file in Windows that plays a crucial role in supporting the exFAT (Extended File Allocation Table) file system. This file system is specifically designed for managing files on flash drives and external storage devices."

Did you have an external drive attached at the time? Frankly if this was a one off event I wouldn't worry about it. It would be helpful to turn on mini-dumps for easier analysis if it recurs.

Answer 3

Hello,

Your .dmp file is too large to download easily. Please follow these steps to collect the mini log file:

Open Control Panel - System and Security - System - Advanced system settings - Startup and Recovery.

Set "Write debugging information" to "Small memory dump 256kb" and "Small dump directory" to "%SystemRoot%\Minidump".

After setting, restart your computer. The next time your computer crashes with a blue screen, a new file will be generated. You can then upload the blue screen file to onediver and provide a download link.

Event ID 1001 “Windows Hardware Error” indicates that Windows detected a hardware-related problem and logged a crash (with a memory dump). Since chkdsk, SFC, and DISM have already been run and no further crashes have occurred, the next step is to verify whether there is an underlying memory issue.

To check for memory problems and confirm whether RAM is involved:

1. Run Windows Memory Diagnostic:
   • Open the Start menu, type Windows Memory Diagnostic, and run it.
   • Choose Restart now and check for problems.
   • Let the test complete; the PC will reboot.
2. Review the memory test results in Event Viewer:
   • Open Event Viewer.
   • In the left pane, navigate to: Event Viewer (Local) > Application and Services Logs > Microsoft > Windows > MemoryDiagnostics-Results > Debug.
   • In the results pane, select the latest entry to see details of the memory test.
   • Event ID 2001 means no memory errors were detected.

If the memory test reports errors, the issue is likely faulty RAM or a memory slot, and the failing module should be replaced. If Event ID 2001 is shown and no further crashes occur, the event may have been a one-time hardware or driver glitch.

If crashes resume despite clean disk, system file, and memory checks, follow the broader guidance in Resolving Blue Screen errors in Windows (linked from the same documentation) to continue troubleshooting drivers and other hardware.
