Hardware diagnostic tool

Hi,

could you please suggest the name of a good tool to diagnose and troubleshoot hardware (standard Intel Pc family) problems?
Possibly not operating system dependent: it would be good that it could self-boot from floppy disk and proceed without depending on MSWindows ...

Thank you in advance ...
Best regards.
Diego.
