pc circuit boards

[species8350]

I would like to undertsand something of the circuit boards in pc's.

Has anyone come across a suitable url which explains the
technicalities (suitable for a beginner).

Thanks

ps. Supplementary question.

Does anyone know how modems can be tested for integrity (if the
circuit is working or not). Most people I have talked to say the only
way is by substituing the circuit into a pc which is known to work.
But surely the manufacturers have a method.

Any references to the component parts (what does what and how) also
appreciated

thanks

Sure they do. Basically, they have a working computer without a case.
They plug in the modem and run very specific software that injects known
commands into the modem and measures its responses. Could you set up a
bench test bed of nails to test a given modem? Certainly. But, by the
time you knew what to put where, you'd learn very little from thae
actual test.
