The booting and shut down processes of the computer, even though seems simple, depend on a lot of back end processes that takes place simultaneously. As the user continues using the same system installing various programs, the slow startup and related issues come up. Sometimes the computer hangs after booting.

After the BIOS, the system loads the programs one by one from the computer registry. Any error of the registry causes slow startup and further slowdown of the system.
