This tutorial is for some of the most common issues
that can occur in a PC. You will also be able to

users may not be able to fix their respective
computer problems but it will definitely help you to
troubleshoot your problems and identify which piece
of hardware is defective.
Step 1:
Is your computer not powering up? Take the case off
the CPU off and check if the lights on the
motherboard are on. If there are no signs that
power is reaching your PC then the problem could
be in any part. It can be the motherboard, processor,
motherboard’s memory or the power supply. Most
modern computers can power up with just the
memory and power supply attached.
You can take a voltmeter and check if the voltage is
3.3. If it is not 3.3 volts this is a bad sign and you
need to replace the power supply. In the event that
there are different voltages coming out of the power
supply this also means the power supply needs to
be replaced. In this case it’s best to consult
a computer repair expert.
Step 2:
Do you turn your PC on and see that it is powering
up and doing nothing else? The hard drive has small
connectors plugged into it. Take the voltmeter and
this time and look at the pins on these connectors.
With the ground connected to the case the voltage
should be +5 and +12 otherwise the power supply is
bad.
Make a drawing of your motherboard showing where
every wire is connected. Disconnect all the devices
from the motherboard other than the memory, power
supply, video card and the processor. Keep the
wires for the lights on the front case and the switch
attached as well.
Turn on your computer it should boot. It should show
the logo of the manufacturer. If an error “System disk
not found” appears then it’s not a problem as you
don’t have the disk attached. If nothing appears then
the problem may be with the motherboard, video
card or the processor and you need to replace it.
Step 3:
Connect the power supply, video card, processor,
power supply and memory on the motherboard. If
the computer does not boot fully then unplug your
PC. Plug in the hard drive. When the computer
powers up, it should spin if it doesn’t unplug the
computer again and unplug the signal cable. If it still
will not spin then it is defective. Check the voltage
again as it is a way to ensure whether the power
supply is the culprit.
If you have some new hardware attached and
computer is not booting remove it and check if it
boots. If the computer boots properly connect all
hardware devices one by one and reboot after
attaching each one. This will help you figure out
which hardware device is faulty.
