Memory address can not be ‘Read’ or ‘Writen’

If windows prompt you with the following error message:

svchost.exe -- application error the instruction at "0x745f2780" reference memory at "0x00000000". the memory could not be 'read'

On further diagnostic:

Faulting application svchost.exe, version 5.1.2600.2180, faulting module msi.dll, version 3.1.4000.2435, fault address 0x00******.

Once this error is closed you can't start anything and XP crashes when trying to shut down.
Fortunately, if you don't close any of the error messages down, Windows still works.

This problem may be due to several factors:

Hardware failure( RAM memory is not working properly or is damaged)

The management of applications running is not effectively achieved by your system

Hard disk is saturated.

Your PC is infected with malwares or virus.

Windows Update is not working properly.
