Your power supply may have failed. Such failure is common, especially with the low quality supplies used in some machines these days. Sometimes this is due to the failure of the fan inside the supply, which causes overheating, and eventual component failure (especially of the electrolytic capacitors). If you have a voltmeter available, you can check for the presence of voltages on the cabling which connects to the computer motherboard, drives etc.

Google for the proper pinout specifications- the cabling has colored wiring.

Have the computer plugged in- first check for the standby voltage- a +5 volt line which powers a small circuit on the motherboard. If this is missing, your machine will not power up at all. If present, then press the ON button, and check for voltages on the red and yellow wires. On the red +5 volts, yellow +12. These should be very close to those exact readings. If more than a few tenths of a volt off (esp. the +5), then the supply is bad also.

I have a bit of an extrapolation on a similar problem. I've got a hercules 500w max power supply on my geforce 6100 sm-m mother board and it died suddenly during use. I went to power it back on and it powered up the fans, but not the hard drives or graphics card, so I shut it down from the swith on the supply, waited a minute, flipped it back on, and... now the blue light for the power switch on the tower doesnt light up, but the restart button light does and the fans power up in the case and on the processor and all, but not the hard drives and still no signal from graphics card either. I looked in the hercules and I dont see any clearly (by eye) popped caps. would you still go down the road of bad supply knowing the hercules is problematic, or would you think maybe cmos battery?
any help would be very much appreciated, thanks guys

Hp pavilion slimline shut itself off and will not come back on.


Sounds like a power supply problem. Usually this occurs when
doing work that involves a lot of memory, and progressively gets worse.
It has something to do with the crowbar circuit that shuts the power supply whets overloaded; sometimes a trigger-happy SCR.
Life is a lot better if you use one of those Ebay power supply testers with an LCD display, but these testers don't draw enough current to trigger a potentially bad crowbar.
Best solution I can think of is purchase another ATX power supply 350w or more with the same dimensions. Pay attention to the lenght of the replacement ps to see if it's too long (front to back) to fit in your computer.
Hope this helps.

My 873 n will not turn on


if you are refering to a computer

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your "((MOTHERBOARD TO YOUR HARD DRIVE))" make sure they have a secure connection and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error even something as small as a faulty electrical extension or fan lead can cause this problem

follow the troubleshooting procedure a computer needs all of the data and electrical current to travel through every device and to have an end to be able work properly

a motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail check all electrical extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working also it could be a dirty computer clean all of the dust from your computer you could use a vacuum cleaner but whatever you use make absolutely sure there is no moisture gets to anything in your computer and before you touch anything be sure to wear an earth strap hope this helps

No power when I switch on computer. Fan not running, power light not coming on. Have tried plugging in to different socket. Still nothing. Taken case side off, double checked all fittings. Cleaned computer...


If you know the receptacles that you have plugged the computer into, indeed have power, I would suggest you diagnose the Power On switch, and the Power Supply.

See of the problem is the Power On switch, or the Power Supply.

A jumper wire is used on the main ATX power cable.

1) If the Power Supply comes on you have a bad Power On switch.
2) If the Power Supply does Not come on, you have a bad Power Supply.

Your problem is posted in the eMachines Bestec ATX-300-12E power supply section.
Going with that we are discussing a Bestec ATX 300 watt power supply, the main ATX power cable is a 20-pin ATX main power cable.

Typical pinout of a 20-pin ATX main power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

Note the Green wire in the BACK of the connector, in the photo to the far right.
This is the Soft Power On wire, or also abbreviated as the PS_ON wire.

Note the Black wires. ANY Black wire is a Ground wire.

With the 20-pin ATX power cable plugged into the motherboard, as shown in the photo, a jumper wire is touched to the Green wire, and to ANY Black wire.
The computer (Power Supply) is also plugged into power.

Generally a paper clip is used for the jumper wire.
The paper clip is straightened out, then bent into a U shape.
Black plastic electrical tape is then wound around the middle of the U shape.
This taped area is for your fingers, and thumb to hold onto.

The 'legs' of the paper clip, are then inserted down into the socket holes, in the back of the 20-pin ATX main power cable's connector.

Down into a socket hole with the Green wire, and also into a socket hole with ANY Black wire.
The 'leg' of the paper clip goes down into the socket hole, RIGHT NEXT to the existing wire.

At the end of every wire in the 20-pin ATX main power cable, is a metal terminal end.
The metal terminal end is pretty far down in the socket.
You must ensure that the metal end of the paper clip, touches the metal terminal.

The voltage is 5 Volts DC.
Two D cell flashlight batteries produce 3 Volts DC.
There may be a small spark as you make the connection.

Warning you in advance.
You can see the voltage is VERY low, however.

I would like you to perform this test, then post back in a Comment as to your findings.

Regards,
joecoolvette

Yes, it's called bypassing the Power On switch. Has nothing to do with the switch itself, or it's wires.

You use a jumper wire on the 20 or 24-pin ATX main power cable's connector.
Touch the jumper wire from the Green wire (Soft Power On) to ANY Black wire. (Ground)
(Soft Power On is abbreviated as PS_ON)

If the Power Supply comes on, the problem is the Power On switch.
If the Power Supply does Not come on, the problem is the Power Supply.

1) 20-pin ATX main power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

2) 24-pin ATX main power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

Look at the photos of the ATX main power cable plugged into the motherboard.
Where the wires go down into the connector is the Back of the connector.

This is where the jumper wire goes down into.

The jumper wire goes down into the socket hole, in the Back of the connector, RIGHT NEXT to the wire IN the socket hole.
The jumper wire has to go pretty far down in the socket hole.

[ATX power cable plugged into the motherboard, Power Supply plugged into power ]

At the end of every wire in the ATX main power cable's connector, is a metal terminal.

A Female Molex Crimp Terminal connector,

http://www.alibaba.com/product-gs/336134982/molex_female_crimp_terminal_connector/showimage.html

[You can click on the Zoom In icon { + } at the top to enlarge the view]

The jumper wire Must touch that metal terminal.
The jumper wire is made from a straightened out paper clip, bent into a U shape.
The middle of the U is wrapped a few times with Black plastic electrical tape.
This where your fingers hold onto the jumper wire.

(One wrap of Black plastic electrical tape is good for 600 Volts DC)

One 'leg' of the U shaped jumper wire goes down into the socket hole with a Green wire.
The other 'leg' of the U shaped jumper wire goes down into ANY socket hole with a Black wire.
(ALL Black wires are Ground wires)

The contact period made is no longer than 2 seconds.

The Voltage is 5 Volts DC.
Two flashlight batteries produce 3 Volts DC.

This is one generic ATX power on switch that I have found fits many computers,

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

NOTE*

WATCH IT when buying an aftermarket Power Supply for your computer, if it needs one.
For a time period Dell was strictly a Proprietary computer manufacturer.
Dell wanted THEIR parts used in THEIR computers only.

They had the motherboard manufacturer switch the pins around in the ATX main power cable connector, on the motherboard.
They also had the Power Supply manufacturer switch the power cables around in the Power Supply.

This means if you plug an ATX main power cable, from an aftermarket Power Supply, into one of these proprietary Dell motherboards, you WILL fry out the motherboard!

Can also fry out the Processor, Ram Memory, and Harddrive. (Plus a graphics card if you have one installed)

CHECK the color code of the aftermarket Power Supply's ATX main power cable, to the color code of the Dell power supply.

See that the color code of the wires matches the socket holes in the connector.

Have further questions regarding this, post in a Comment.

I have a desktop. when i turn it on nothing happens.


Test whether the problem is the Power On switch, or the Power Supply.

The Power On switch is located inside the plastic Power On button. It's removable in most cases.
This is a typical ATX power on switch,

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

To test you will bypass the Power On switch.

If the Power Supply comes on, you have a bad Power On switch.
If the Power Supply does Not come on, you have a bad Power Supply.

The test doesn't involve the Power On switch, or it's wires.

It involves the 20 or 24-pin ATX main power cable, the Soft Power On wire, (Green), and ANY Ground wire.
(Black)
A jumper wire is used from the Green wire to ANY Black wire.

Computer unplugged from power, observe Anti-Static Precautions, BEFORE you reach inside.

Anti-Static Precautions:
Your body carries Static electricity.
Static will fry out (Short Circuit) the hardware components inside a computer.
Computer unplugged from power, TOUCH the metal frame of the open computer case. Touch an unpainted surface.

This action will relieve your body of Static.
Should you leave your computer in the middle of working on it, be SURE to Touch the metal frame again upon your return.

You may have to ease a few cables over to view the motherboard.
You are looking for the 20, or 24-pin ATX main power cable.
(Don't know if your model uses a 20-pin, or a 24-pin.
This is what you're looking for,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

Scroll down to see the 24-pin ATX main power cable.
Look at the photo to the far right.
The Green wire is the Soft Power On wire.
ANY Black wire is a Ground wire.

With the ATX power cable plugged into the motherboard, as shown in the photo to the far right, you are going to insert a jumper wire down into the socket holes.

The jumper wire goes down in the socket hole, Right next to the wire that is in the hole.
It goes down in far enough to touch a metal terminal, that is at the end of the wire.
(Approximately 1/2 inch)

The jumper wire of choice is a paper clip straightened out, then bent into a U-shape.
The middle of the U is wrapped a few times with black plastic electrical tape.
(Trivia: One wrap of black plastic electrical tape is enough for 600 Volts DC)

The voltage you will be dealing with is 5 Volts DC.
Two D cell flashlight batteries produce 3 Volts DC.

You may wish to wear a glove on the hand that holds the jumper wire. There may be a small spark.
The Power Supply, (Computer), is plugged into power.

One end of the U-shaped jumper wire, is inserted down into the socket hole with a Green wire. (Right next to the wire)
The other end is inserted down into a socket hole with ANY Black wire.
The contact made is no more than 2 seconds. (1001, 1002)

If the computer comes on, (Power Supply actually), the Power On switch is bad.
If the computer does not come on (Power Supply), the Power Supply is bad.

System is not workin properly


You might try this. Shut down the computer, disconnect power cords, disconnect everything at the back of the computer, mouse, key board, etc. Open the case, ground yourself by touching an unpainted area of the case and remove the power connectors to ALL optic drives and floppy drive if you have one. (Of course do not disconnect the hdd.)
Reconnect mouse, keyboard, etc., and power cords to wall outlet.
See if it will post now. If it does I say you have a faulty power supply.
I was given a computer which was doa. It would not post, after I tried the above routine it posted then booted to windows.
I replaced the psu and now the computer works fine.
Hope this helps!
