Basic Troubleshooting is mostly common sense, is it on? No then turn it
You don't need a fully equipped computer repair shop!
Because it is
an art, it is not an exact science.
Some experts will say that to troubleshoot
a problem (the IT people call it an issue) you have to have the education, training, and experience in the
Ummmm, no I don't think so.
You can recognize a problem with your car,
you air conditioning, the wife's washing machine, etc. You can tell if the
impeller in the washing machine isn't turning, if it isn't turning it isn't
agitating the clothes to clean them. So there is a problem between the motor and/or
the impeller. You call an expert in washing machine repair and they fix it.
Troubleshooting, you go through your day and do it all the time, troubleshooting is just problem resolving. The difference is that the problem resolving
is with electronic/mechanical items not humans.
Basic Troubleshooting (TS) is like a tree, at the top is the problem, each branch
has a yes or a no. Yes will take you in one direction, a no will take you

(IT) tool box.

Basic Troubleshooting techniques:
Before going off to find the bad part, think for a

If not then proceed. If you changed something try to put it back the way it was
then if the problem persists proceed.
is common sense, then there is the logical sequence,
then there is the actual dang! I figured it out! So follow the sequence of TS
down the tree.

No - go to
Yes - go to
Is there power to the receptacle that the computer uses?
Is the computer plugged in? Both the receptacle and the computer power
supply, remember that the power cord is removable from the computer.
We have power, did it start?
Yes - Done!
No - go to other problems
Installing devices, have you installed any new hardware?
Yes - go to
installing new hardware.
No - go to
power supply Troubleshooting
If you have power and the computer powers up (the power led is glowing) but
there is a lack of activity (i.e.: nothing on the screen) or you get a blinking
cursor and nothing else then we move on to the No Start section.
