Help! My PC Keeps Crashing with a PCI.SYS BSOD

I took a look at your minidump output, and it seems like the crash is linked to the PCI driver, specifically involving "ExpressSwitchUpdateLinkLatency". This could indicate an issue with your PCIe configuration or related drivers. Check your BIOS/UEFI for any settings linked to PCIe latency adjustments. Additionally, ensure your BIOS and all device drivers are updated. If you recently upgraded your GPU, ensure the drivers are cleanly installed, as leftover files from the previous GPU can cause issues.

The crash appears to be triggered when the PCIe subsystem tries to add a device, so check Device Manager for any indicated issues. Sometimes integrated devices on the motherboard also use PCIe, so it's worth looking into that. If there aren’t any obvious problems reported, we might have to do some guesswork. Have you noticed any specific devices or components malfunctioning, or is your NVMe storage functioning as expected? That can also impact PCIe stability.

To effectively analyze your BSOD, it's crucial to get the dump files. If you can boot into Windows, either normally or in Safe Mode, check the C:WindowsMinidump folder for any minidump files. Zip the folder and upload it to a file-sharing site like mediafire.com or catbox.moe, since Reddit has restrictions on links. Also, try to gather multiple dump files for better accuracy. If you only have one, make sure to follow the guide on creating Small Memory Dumps to ensure you gather more in the future.
