A6660z Desktop won't power on

First make sure that if the computer is plugged into a power strip, that the actual strip did not trip during the outage. There is normally a little button on the end of it that resets the power. You can also check this by plugging something else into the power strip to see if that powers on. Otherwise the power supply on the computer may be out and is usually about $50 to replace.

Worst case is the motherboard/hard drive had a complete failure...

My Gateway DX 4300-05 won't start. Not even the power supply. Does the motherboard have a reset?

If I am reading the frist part of your stament correctly, the power supply does not even kick on when you press the power button. Don not unplug anything from the inside of the computer at this time, instead check your power cord and make sure it is plugged in thightly to both the computer and power strip. Check to make sure the power strip is on, plug something else (like a light) and test the power strip. If the item does not come on, then you may have a bad power strip. To confirm plug the item you are testing with into the outlet the power strip is plugged in to and see if it works. If not your outlet may be bad, contact an electrician. If everything works, but the power supply is still not kicking on, you possibly have a bad power supply. You will need to pick up a replacement power supply and install it in the computer. This is were you unplug everything wire bundle that comes from the power supply to the mother board (paying attention to what was plugged in where). Take the new power supply, install it, plug everything back in. Now try the power button. If this fails then yes you have a bad mother board.

I know most computer retailers that offer repairs, have a device to check the power supply. A good repair place will check this at little or no cost to you, if you agree to let them install the replacement if it is bad (they will charge you for the power supply and installation of it).

I hope this helps

We had a thunder storm a few days ago and that we lost power and that the pc shut down by it self so the next day we try to turn on the pc so it won't turn on please can you help us

Make sure that all the plugs are plugged in. Try a different outlet, if it's plugged into a surge protector make sure that it didn't trip. Or if is plugged into a regular power strip press the reset button on the side of the strip. If that doesn't work there usually is a fuse inside the PC that might have blown.

I need a diagram for the wiring inside a Gateway GT4016

A wiring diagram? What for? Are you trying to re-solder the caps? Because the only wiring inside computers these days is power cabling, and thats pretty self explanatory. If you are looking for the die for the motherboard, I would try contacting the manufacturer. but chances are they would not give it to you. If you are just trying to plug in a drive or something similar, the flat plugs are the ones that plug into drives and the long 24 pin connector is the power for the board and the 4-8 pin connector is for the secondary motherboard power (CPU Power).
Short of these, I can't really give you a better response without knowing exactly what you are trying to do.
I hope this helps though :D

Compaq presario sr2030nx won't boot. The fan

Bad Power Supply.
Weak Voltage power rail.

I'm going to explain what is wrong, and why.

Power Supply's are rated in Wattage.

The Power Supply used in a Compaq Presario SR2030NX desktop computer, is a 300 Watt unit.
(ATX style)

1) ALL the lights use Less than 1 Watt of power.
2) EACH fan uses 2 to 3 Watts.

3) A typical Processor uses 51 to 125 watts. Depends on what Processor it is.

The Compaq Presario SR2030NX uses an AMD Athlon 64 X2 3800+, processor,

The AMD Athlon 64 X2 3800+ processor can use Up To 89 Watts, (Windsor Core)

(HP Support lists the Processor as an Athlon 64 (O) 3800+.
The (O) should be an X2)

This means your bad Power Supply has enough power to light lights, and spin fans, but not enough to turn the Processor on.
No Processor running, No computer.

Bad Voltage power rail.

Inside the Power Supply are Electrolytic Capacitors.
Electrolytic Capacitors can break down.
The capacitors are used as Filters.

They filter the incoming AC electricity (Input Stage), and the outgoing DC electricity made by the Power Supply. (Output Stage)

(Observe the photo to the upper right of the page. The photo can be enlarged by left-clicking on it. It can be enlarged twice)

Electrolytic Capacitor simplified construction:

The Electrolytic Capacitors used in the Power Supply, (And on the motherboard), of a Compaq Presario SR2030NX, are Aluminum Electrolytic Capacitors, which are of the Radial design.

Observe the two photos of capacitors, shown at the upper right of the page.
The Electrolytic Capacitor example shown at the bottom, of the bottom photo, is the Radial design.
(Short blue capacitor)

The case of the capacitor is an Aluminum 'can'.
Inside the aluminum can are three strips.

1) One strip is an aluminum foil, and is the Conducting strip.

2) One strip is an aluminum foil, and has a non-conducting medium applied to it.
This is the Non-Conducting strip.

3) The last strip is a paper-like medium, and is soaked with Electrolytic paste.

The paper strip soaked with Electrolytic paste, is placed in-between the Conducting, and Non-Conducting strips, and all three strips are rolled up tightly.

(The Positive lead of the capacitor is attached to the Conducting strip. The Negative lead is attached to the Non-Conducting strip)

When a capacitor breaks down the paste inside develops a gas. (Hydrogen gas)
This gas expands inside the case of the capacitor (Can)

At the bottom of the 'Can' is a seal. It is a synthetic rubber like material, and is shaped like a flat disk.

The top of the 'Can' has a shape etched part way into it.
The shape is commonly an X, or K.

When the gas expands, and develops enough pressure, either the seal at the bottom is compromised, And/Or the etched shape breaks open, to relieve the pressure.

The Electrolytic paste is pushed out.
So much paste loss, and the capacitor operates at a weakened state.
To much paste loss, and the capacitor fails.

A Capacitor as a electronic component that slowly develops a charge, then releases it all at once.

You may compare it to a large swimming pool being filled up by a garden hose, then one wall of the swimming pool is taken down all at once.

This is why the Power Supply worked when you unplugged it for a while, then plugged it back in.

The weakened capacitors paste chemical composition, allowed the capacitor/s to revert back to a working stage once power was removed.
(Power Supply unplugged from power)

When you plugged the Power Supply back into power, the capacitor/s were working again.
Worked with so much paste loss.

Eventually enough paste was pushed out, and the capacitor/s have failed.

What causes Power Supply failure?

1) The inside of the computer is dirty, as well as the inside of the Power Supply.

The cooling components of Power Supply is it's fan, and Heatsink's located inside the Power Supply.
[Refer back to the photo of the open Power Supply, in the SMPS link]

(A Heatsink is a component, that draws heat away from another component.
Typically, a Heatsink is composed of a flat metal plate, that has tall, thin fins protruding from it.

Heat is absorbed into the flat metal plate, whereby it is absorbed into the tall, thin fins.
The fins radiate the heat away.

When a fan is used in conjunction with a Heatsink, the air produced by the fan goes in-between, and around the fins, and helps carry heat away)

When the fan's blades, center hub, and surrounding cage are dirty, and the Heatsink/s are dirty, the cooling capacity drops tremendously.

Again, Heat = Wasted Energy.
The Power Supply tries to keep up with the call for power, and eventually components inside the Power Supply fail.
Electrolytic Capacitors are the weakest link, and typically fail first.

2) The computer manufacturer used a cheap quality Power Supply.
Cheap quality components used inside the Power Supply.

If you wish I can guide you in testing the Power Supply.
You'll need an inexpensive multimeter, or an inexpensive power supply tester.

(One example of an inexpensive power supply tester, )

Or if you have a KNOWN to be good, compatible power supply, you can use it for a test unit.

Need help in finding a replacement Power Supply, or information in how to replace it, simply state so in a Comment.

Dead in the water?

Power supplies, depending on your demand, can cost you as little as 35 bucks. However, eMachines, power supply physical design is a bit different than most. Here is how you can bench test your supply to rule out any other problems. Unplug your machine. Make a simple diagram of what cables from the supply goes to what, including the ones that go to the motherboard. Next, Disconnect all of that. On the large cable that connected to the motherboard and locate the green wire. Now find, somewhere other than inside your pc. A small piece of wire (with both ends stripped of insulation) to use as a jumper. Stick this wire in the hole where the green wire ports to and the other end to any black wire port. Plug your supply back into the wall. If the PS is good it will fire right up. If not, you need to replace it.

Hope this helps!

Computer won't turn on

check that the switch on the power supply has not been accidentally bumped.

It should be on the - side... not the o side.

There could be a variety of other problems including the power switch.

Possible reasons a PC will not power up:

Failed Power Button.
Power strip breaker tripped - are there other items plugged in that work?
Failed memory Module.
Failed CPU.
Failed CPU Cooling fan.
Failed power supply.

You will need to test each item with a Digital Multi Meter (DMM) and verify 12VDC at each item. CPU and Memory can only be tested externally by a shop with a reader.
