Reporting repeated BSOD messages about unhandled PCI.sys system thread exceptions
Reporting repeated BSOD messages about unhandled PCI.sys system thread exceptions
Hi,
I tried without XMP and PBO again. After reflashing the bios before updating to the latest version, the problem persisted—memtest confirmed memory was fine and pbo worked until the GPU change. I’ll test with default settings and let you know if it happens. Thanks for your time.
if the motherboard chipset update fails to resolve the issue, consider accessing the Device Manager.
Click right-click on “AMD PCI Express Upstream Switch Port,” choose “update driver,” then select “Browse my computer for driver software.”
Next, pick “PCI Express Downstream Switched Port.”
Note: A new BIOS was released for your machine (release date 5-6-2025).
The debugger indicates several mismatches in check sums involving certain core files, such as pci.sys.
It might be worth searching for an update specific to this AMD file:
Image path: AMDPCIDev.sys
Image name: AMDPCIDev.sys

It’s advisable to supply the kernel dump and verify the device name for accuracy.
It appears the motherboard may also require a chipset update.
All bugcheck dumps remain consistent; you should switch the memory dump type to “kernel” and provide the corresponding kernel dump (memory.dmp).
Plug and play encounters access violations during changes.
A kernel dump will reveal the vendor and device code for the faulty component, allowing you to identify the vendor ID and device name from the code.
Most recent bugcheck issues stemmed from plug and play attempting to add a device and triggering an access violation.
Changing the dump type to kernel is necessary so the memory.dmp file captures the correct details to diagnose the failure.
Several outdated drivers were installed; further analysis will follow if patterns emerge in other dumps.
Based on those dumps, it's recommended to remove Malwarebytes entirely. The mbamchamelon.sys driver appears in all of them, and it's quite outdated.
Hi,
Thank you for your message. I’ll make sure to follow up on getting the requested items. Since I’m unsure about kernel and memory dumps, I plan to figure it out later today or tomorrow and share the results here. In the meantime, I’ll remove Malwarebytes and check if anything changes.
search for instructions on configuring Windows to generate a kernel memory dump. After the system detects issues, upload the memory.dmp file to a server, make it publicly accessible, and share the link.
