13. Click on the “Startup” tab and remove the check marks next to any programs that you recently installed. Do not remove the check marks next to “userinit.exe” or “explorer.exe.” Do not remove the check marks next to any other Microsoft programs unless you know what it is.

15. Press “Enter” when “Last known good configuration” is highlighted to attempt to boot Windows with the last settings you had that worked. If Windows loads normally, it should get rid of the fatal blue screen. Do not reload any software or drivers that you installed after the last good restore point.
16. Remove any hardware you installed in your PC and any new peripherals, such as external hard drives or CD drives, before the fatal blue screen appeared. Attempt to reboot your computer.
