Hello,
I have a good background in electronics and troubleshooting, but need
some help in how to troubleshoot microprocessor circuits/ computers. Are
there any techniques that help to determine if a processor circuit is
working properly other than just running it, and if there is no
troubleshooting software for it? Is it just a matter of checking to see
if
data is moving? How can you tell the data is correct? Any help in
troubleshooting these types of circuits is appreciated. Thanks.

You pretty much can't. Most computer shops don't even own a DMM.
