software that was preinstalled (or that you have installed) on your hard
disk. The programs run independently of the operating system, and must
be run either from CD or diskette.
You can use this program to test the hardware (and some software)
components of your computer. This method of testing is generally used
when other methods are not accessible or have not been successful in
isolating a problem suspected to be hardware related.
