Believe it or not, even with all of the info on this site, some people still manage to come up with stuff that no one here ever heard of before, its rare to find a new one, but we have always figured it out eventually.
A good challenge is always fun. Especially if I aint paying the bill.......
Some people trouble shoot by throwing money at the problem till it goes away, and others want to find and isolate the issue, its cause and needed fix.
Many times it can be fixed faster by guessing and tossing money at it but at a much higher cost. Finding the real problem usually takes longer but ends up costing less. Pick your poison.
