If your becomes stable again but you really need those changes to work you could try to clean your system registry and then try to make your required changes. If your recent change was a new piece of hardware be sure it is properly installed and that you are using the correct drivers.
Perform Windows Updates and install all updates and service packs. It is possible that Microsoft has released a patch to fix the STOP Error you are receiving.
