UNMOUNTABLE_BOOT_VOLUME means Windows cannot read its own drive at startup. Save your files, repair the volume from WinRE, and rebuild boot files, in order.

PFN_LIST_CORRUPT means Windows' index of physical memory pages was damaged. Test the RAM first, then the storage driver: here is the order that works.

KMODE_EXCEPTION_NOT_HANDLED means a kernel-mode program hit an error nothing caught. Find the driver behind it and stop the crashes with these ordered checks.

BAD_POOL_HEADER means a driver corrupted Windows' kernel memory pool. Track down the driver, antivirus, or RAM stick behind it with these ordered checks.

This blue screen usually names the driver that crashed, right on the screen. Read that .sys file, roll the driver back, and stop the reboot loop for good.
