After upgrading the CPU in the Windows 11 system, the PowerShell window frequently crashes.
After replacing the CPU, the system frequently experiences PowerShell windows crashing instantly, accompanied by numerous PowerShell processes in Task Manager. This is suspected to be related to hardware upgrades or driver compatibility issues. Troubleshooting approaches and solutions are required.

It sounds like the new CPU may have triggered driver or compatibility issues that are causing PowerShell instability. I’d suggest first updating your chipset drivers, BIOS/UEFI, and Windows updates, as older versions can conflict with new hardware. Also check Event Viewer logs for faulting modules — sometimes third-party background services tied to old CPU power management or virtualization features can repeatedly spawn PowerShell processes. If nothing helps, try running sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth to rule out system corruption, and consider a clean driver reinstall.
