Recently a Device was installed/updated on the laptop and the driver for this device is causing the bluescreen.
Safe Mode doesnt make it easy to Uninstall/rollback however.
I have to assume at some point while booting you hit F8 and tried the choice that says
"use last known good configuration".
Memory could be the issue also.
Not an easy one to troubleshoot tho
good luck!
