When the computer crashes and restarts, the contents of physical RAM are written to the paging file that is located on the partition on which the operating system is installed.
Depending on the speed of the hard disk on which Windows is installed, dumping more than 2 gigabytes (GB) of memory may take a long time. Even in a best case scenario, if the dump file is configured to reside on another local hard drive, a significant amount of data will be read and written to the hard disks. This can cause a prolonged server outage.

>Use this method to generate complete memory dump files with caution. Ideally, you should do this only when you are explicitly requested to by the Microsoft Support engineer. Any kernel or complete memory dump file debugging should be the last resort after all standard troubleshooting methods have been completely exhausted.

### Use NMI
On some computers, you cannot use keyboard to generate a crash dump file. For example, Hewlett-Packard (HP) BladeSystem servers from the Hewlett-Packard Development Company are managed through a browser-based graphical user interface (GUI). A keyboard is not attached to the HP BladeSystem server.

In these cases, you must generate a complete crash dump file or a kernel crash dump file by using the Non-Maskable Interrupt (NMI) switch that causes an NMI on the system processor.
