Hi all. The problem I'm having is that my computer didn't start at all I was
working on it before but after a while the power was gone for half day after
that when the power come back and when I tried to SWICH ON there is no any
sign at all I don't know the reason.

Thanks
 
It appears your computer was physically damaged during the power outage.
If your computer will not power on, you may suspect that it's power unit
has failed and will need replacing.
You can test this by swapping the power unit with a known good one and
attempting power on again, when this is successful you will know what to
do next.
 
Verify the wall outlet is providing power; plug a lamp into it for a test.
When the power went out it may have popped a circuit breaker.

Also check to see if the power switch on the back of the computer is in the
on position.

For future protection, consider getting an Uninterruptible Power Supply
(UPS). It will protect your computer.
 
Packard Bell computers have a reputation for being poor quality. Hopefully
it is only the power supply that is damaged.

You should get a battery backup (also known as a UPS) so you have time to do
a shutdown when power is lost. If you don't even have a surge supressor,
then definitely use one. A surge supressor might have been enough to protect
your computer hardware.
 
Is the monitor turned on? Some monitors will actually turn off when the
power is cut.
 
This is quite common. The PSU is probably faulty. PSU's contain a startup
circuit, and if this fails it will have no effect until the next time the PSU
is completely de-powered. Thus, the fault might have developed months ago,
and if you never unplug your computer it will continue to work until the
powercut.

Provided it's a standard PSU, replacement should be fairly inexpensive.

A UPS provides no surge protection (unless it specifically says so by
including additional circuitry beyond the UPS function). Most UPSes
that state they include surge protection are extremely poor surge
protectors, but then most end-point surge protection is worthless,
especially considering how users connect non-protected lines to a
computer (telephone for modem, audio between computer and stereo
system, powered speakers or monitors that are not on the same side of
the surge protector, using multiple surge protectors in parallel
rather than serial, etc.)

A UPS is for *data* protection, not for hardware protection.

Please review your posts before submitting.

If you don't see the power LED come on at the front of the case, if
you hear no fan noise, if you don't hear the hard drive spin up, and
if a table lamp works in the same outlet to which you plug in the
computer then you have a dead power supply, broken power switch, a CPU
fan that isn't spinning, a component that isn't plugged in completely
(CPU, memory), a dead battery (if what you have is a laptop but you
never mentioned what you have), or some other component got damaged
during the spikes in the power outage.

Considering your post composition, you will have to take the computer
to a shop to have them diagnose your problem - if the problem is with
your computer. Did you check the computer is actually plugged in and
that there is power at that outlet (by plugging a known working table
lamp into that outlook and turning it on)? Do you see the LED is on
for your monitor (if you have a desktop computer)? Is the power LED
lit on your computer (for desktop or laptop)? If you have your
computer plugged into a surge or power strip, did you check if its
switch is in the ON position, and if it has a breaker that popped?
