My PC when plugged in does not turn on but only powers the fan

I have plugged in my PC, and when i press the on button, only the fans switch on, when I remove the power cable the light on the main start up button flickers so it seems the power supply is knackered? Anyone know what could be wrong or if they have had a similar problem? Thanks Chris

Is there beeps coming from inside the tower case? Does the Hard Drive make a spinning sound after about 15 to 20 seconds? It could be a mother board issue, it could be a graphics card issue.

    no beeping at all, all that happens is the fans turn on, i hear nothing else. My computer was working fine, this was 8 months ago, i bought a laptop and never really used my PC again, so it has not been turned on in 8 months.

Emachine EL18252 G-52W won't start when pushing power button


Disconnect the desktop computer from the electrical power.
Plug it in, while looking at the computer, and listening for any noises (spinning fans, or lamps that light up) as soon as it is plugged in. Then, press the ON/OFF switch, and watch any lamps, and listen for any fans. If nothing, then the power-supply is the problem.

When the computer on/off button is pressed , the CPU fan and tower exhaust fans start running, the blue light around the power button does not light and the boot up process goes no further. Fans continue...


A) When you hold a Power On button, (Switch actually), in for a count of 10 seconds, it turns the computer off.

(There is a Power On switch, located behind the plastic Power On button. Usually, the Power On switch snaps into the housing of the plastic Power On button.

Example of a typical ATX Power On switch,

http://www.directron.com/atxswitch.html

The Power On switch turns the Power Supply on.

Old computers had a metal rod, that when the Power On button was depressed, the button pushed against the metal rod, which in turn pressed against a power switch located inside the Power Supply.

The design after that, was a power switch located in the Front Panel. (Plastic front of the computer) A large cable, (Wire) ran from the switch to the Power Supply.

Now there is the Soft Power On feature. (PS_ON)

The Power On switch is a small Momentary Contact Switch. Pressing it closes a circuit. The Soft Power On circuit.

When a power supply is plugged into power, there is a constant 5 Volts (DC) present.
This is the 5 Volt Standby.

Closing the Soft Power On circuit, redirects the 5 Volt Standby power to a circuit within the Power Supply.
This in turn 'excites' the Power Supply, and turns the Power Supply on.

Sorry to be windy, but I wanted you to know how the Soft Power On feature works )

eMachines are a budget computer. As such they save the consumer money.
However in order to do this, the manufacturer will install low quality parts, in some areas of the computer.

One such part is the Power Supply.

1) ALL the LED lights combined use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts

3) A typical Processor can use 51 to 125 Watts.
Depends on what Processor it is.
(Had you stated the Model Number I could have told you)

Enough power to spin fans, but not enough to spin fans, AND turn the Processor on.

Do you have access to another computer that is unused, but has a Known to be good, Compatible power supply?
It could be used for a test unit.

Tell me the Series, and Model Number of your eMachines, and I'll tell you what Wattage it should have, and what power cables, for the Power Supply.

(Some examples of Series, and Model Numbers, T1090, E4264, W2925, and so on. The T, E, and W are a few examples of the Series letter.
The numbers following the Series letter, is the Model Number)

If you wish I can direct you in removing the Power Supply, and installing the test unit. (And/Or a new Power Supply)

Computer turn on, but when it does it won't POST


It seems like a motherboard issue. It heats up, thus is not able to turn on continuously. You may need to check internal parts embeded on the motherboard llike the fan and processor before you could know what needs replacement.

Ceiling fan stuck on high


The Inteli-Touch system does have a slight learning curve.

How the system works is. You turn the power switch on, and leave it on, all the time. To set fan speed, you press and HOLD the fan button and it will go. . beeeep. beeeeeeeeep. beeeeeeeeeeeeeep. beeeeeeeeeeeeeeeeeeeeep beeeeeeeeeeeeeeeeeeeeeeeeeeeeep beeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep (higher pitched) when you reach your desired speed you let go of the fan button and it stays on that speed. So if you want to go to speed 4 you wait for the fourth beep and let the button go. To turn off the fan, press and release the fan button, to turn it back on to speed 4, press and release again. It has a memory. If you want to go to a higher speed while on speed 4 (or any other speed) just press and hold. To slow down the fan, you must turn the fan off by pressing and releasing the fan button, then pressing and holding until you get to the speed your desire.


The instructions which came with the fan should explain the rest. After you get used to using the IT control system, you will love it. I do. I have two Casablanca IT Victorian II fans in my living room. They are featured in this video. http://www.youtube.com/watch?v=2pv55wZqohs

Power up problem


Hi, you most probably have a sticky on/off switch on your case. Turn the power off. Remove the side cover, trace your wires from the front switch to the mobo, identify witch is the power switch [this is usualy marked with PWR or PWS on the board and also on the wire from the switch. Disconnect this wire then turn on the power and use a fine screwdriver to bridge the two pins on the board, if all works properly then replace the switch Regards mistyman
