VIII Think like Sherlock Holmes
We have said this several times before,
a PC has a collection of spare parts flying in close formation. Sometimes
an issue in one area that may at first seem unrelated, is in fact the
root challenge point. Here is a trick we have learned the hard way.
You have an issue where the system re-boots without it appearing to
have any particular pattern as to when or why. Take the parts out of
the case, and see if the challenge continues. If not, suspect an electrical
issue, such as a ground issue. This shows up often in very inexpensive
cases. This is because of poor spot welds or differences in types of
metal used. If you cannot get a new case, ground several different points
of the case, (drive bays and the rest of the frame to the power supply
using leads with alligator clips to see if the issue disappears.)
The point here is to use the process
of elimination, while not closing your mind to possibilities.
Remember, Sherlock Holmes always
said, “Eliminate the impossible and, no matter how improbable,
whatever is left must be the answer”.
