Long beep from the power supply

I bought different parts to assemble at home. I've connected everything according to standard but the power supply gives a continuous long beep/whistle when I switch on the power button. What can I do? Where is the problem?

Why does my LS 4278 scanner beep when cradled?

It sounds like the power is dropping along the 15 foot length of the cable. You could try connecting a power supply to the cradle and should not hear those beeps any more. The part number of the power supply is PWRS-14000-253R. All of this assumes you are using the STB4278 or CR0078-SC cradle to connect. If you have a CR0078-P cradle it needs a different power supply.

Emachines won't send signal to screen, when turned on it makes one long continuous beep

The beep signifies an error. But different bioses have different beeps. You can check with the emachine site to tell you what 1 beep on the machine signifies and you can be guided accordingly. Could be bad power supply, connection, peripheral, etc

Connecting my ps3 to a jmb tv?

Do you mean the TV is on AV or the PS3 is on AV? Either way, try this, it will not hurt your PS3 at all!
Turn off the ps3, then hold down the power button until you hear the second beep, then can take up to a minute. Once you hear the second beep allow it to boot normally.
My friend swears you need to do this with the ps3 powered on. But I don't think so, but just in case the original solution doesn't work, try this.
If this doesn't work, it's probably a problem with the cords, or the tv.

I changed the power supply on my acer aspire e700 and it beeps continuosly non stop with no picture on screen, the last power supply blew. it had a graphics card when i bought it but it stopped working so...

You may have more problems than just he power supply from when the old power supply went out. The mainboard could be bad.

Make sure it's unplugged from power from the wall, then check that the memory is seated correctly. Check for anything else that may be out of place or not fully connected.

There are also different beep codes for different errors. They've mostly been standardized, but may vary by mainboard as well. Here's a link to common POST beep codes and their meanings:

I am slowly rebuilding my computer. When I nearly got it finished, and turned it on, it came up with "Windows Was Not Found". Knowing what to do, I turned everything off, unplugged it properly, and...

Check for motherboard. use only 3 parts:


Connect your motherboard to PSU and see, if any LED light comes from motherboard. If LED is on, then try to turn motherboard on and see if cooler works.
Are case wires (power +, power -, hdd +, hdd -, reset+, reset -, power led+, power led - and speaker wire ) connected correctly?
Those wires look like this:

front-panel-headers-nsatmeh50lx5u1woeaeqllmn-4-0.jpgThis image is just reference.
If the power wire (sometimes called POWER SW) is not connected correctly, when you press the power button of case, PC just won't turn on.

If PC turns on and CPU fan spins, then try to add RAM, Graphics card and try again.
Next step is to hear BEEP sound. One short beep sound is normal, anything else is not normal and indicates the problem of the specific hardware according to the sound code. Sound code is BIOS dependent. In case ASUS A8V-E Deluxe, it is Award BIOS. Check below for Award BIOS beep codes

1 long, 2 shortIndicates a video error has occurred and the BIOS cannot initialize the video screen to display any additional information

1 long, 3 shortVideo card not detected __ (reseat video card) or bad video card

Beeps repeating endlessly __ RAM problem.

Repeated high frequency beeps while PC is running __Overheating processor (CPU)

Repeated beeps alternating high & low frequency ___Issue with the processor (CPU), possibly damaged

Decoding the number of beeps may be possible with the owner's guide but this type of problem is normally due to a failed power supply.
These are often mounted on separate boards located in the bottom of your set and can be identified by the much larger parts you see on the board and possibly its relationship to the AC cord coming in. While these can be repaired, the cost of that will approach the cost of a new assembly.
Unfortunately, modern, more energy-efficient power supplies have some critical components that if bought cheap, don't last very long and frankly, 5 years isn't bad, I read of many dead within the first year.

One long beep.

  1. Leave the memory slot closest to the processor empty and try booting again. Award bios 1 long beep is memory error as the first 64K of the ram stick closest to th processor is accessed first. since you have tried different ram in different locations, let's rule out the board.
  2. If that doesn't solve anything try a different power supply. Sometimes (Phoenix) gives a long beep when system board or power supply are bad.
  3. Now if nothing else has worked it is probably tour mother board.
