 Computer
won't start. Power on
button light flashing.

How annoying it is when you get a problem with
your computer. One minute they are fine, and the next thing you know it is
basically dead. I especially hate it when you press your power button and
nothing happens. The button just starts blinking or flashing and nothing
comes up on the screen. It seems like the computer is sending me a signal,
but what is it trying to say?

Unfortunately different makes and models of
computers do different things for which could be the same error causing
the problem. Some computers have a beep sequence code and others have no
signals at all. However when it comes to the computer not starting and
the power light flashing on and off I always test the power supply
first.
You can also take the side of your computer
case off to listen for the cpu fan starting when you press the button.
If it seems a bit slow and quiet you can almost guarantee that there is
not enough power getting through to your computer. If you have a spare
Power supply hanging around and you have done this type of thing before,
try swapping them over. If you are not confident in working on computers
yourself, get a professional to do it for you. |

I was working on a computer with this problem a
few years ago, and it turned out to be the power cord. It was faulty, which
allowed the computer to work most of the time, but then other times it would
not boot and the power light flashed. This was a rare because the problem is
usually the actual power supply itself.
If this doesn't work for you, try removing
everything that is connected to your computer. Remove the mouse, keyboard,
monitor, PCI cards, graphics cards, etc. Now you should only have the power
cable connected. Turn the computer on now. If the blinking power light is
gone and it seems ti be running, this could mean that there is something
wrong with one of the components you have just removed. Replace them one at
a time, testing to see if the computer works each time. When the flashing
light comes back you know you have found the problem.
If
changing the power supply didn't help, or removing all of
the components either, it doesn't look good. Now it could only be the cpu or
the motherboard.
