SECURE_PCI_CONFIG_SPACE_ACCESS_VIOLATION, explained
On PCs with virtualization-based security (VBS) and a supporting BIOS, Windows blocks drivers from mapping PCI configuration space directly; they must use the proper bus interface. Drivers that bypass it trigger SECURE_PCI_CONFIG_SPACE_ACCESS_VIOLATION.
Reported cases include older CPU-Z and Speccy drivers. Microsoft's documentation lists this as bug check 0x1EA.
Symptoms
- Blue screen with “SECURE_PCI_CONFIG_SPACE_ACCESS_VIOLATION”.
- Crash right after opening a system-information or monitoring tool.
What causes SECURE_PCI_CONFIG_SPACE_ACCESS_VIOLATION
- Outdated hardware-monitoring or tuning drivers.
- Other drivers accessing PCI config space incorrectly.
Try these fixes
- Remove or update monitoring toolsUninstall or update CPU-Z, Speccy, older hardware monitors and RGB/fan utilities.
- Find the driverOpen the newest file in C:\Windows\Minidump with WinDbg and run
!analyze -v; the named .sys file is the culprit. - Update drivers and BIOSInstall current chipset drivers and BIOS.
- Keep security features onTurning off Memory Integrity/VBS can stop the crash, but it lowers protection. Prefer updating or removing the driver.
Avoiding it in future
Use up-to-date monitoring tools from their official sites.
