The hardware and software for each system needs to be examined separately. A quick assessment of operating system and application software may be gained by looking at date fields within the application. This does not necessarily mean that your system will fail.
System failure results from the way the software and the application uses dates.
Computer users must also be aware that if they receive data from an internal or external source, they must ensure that the data source is Year 2000 compliant. Hardware also needs to be checked for Year 2000 compliance. A compliant software product resident on a non-compliant hardware base may fail. Personal computers are easily checked. Any test must interrupt the boot process before the personal computer receives the network date, or the test will be invalidated.
