Here are some common steps a POST performs each time your computer starts.

  1. Test the power supply to ensure that it is turned on and that it releases its reset signal.
  2. CPU must exit the reset status mode and thereafter be able to execute instructions.
  3. BIOS checksum must be valid, meaning that it must be readable.
  4. CMOS checksum must be valid, meaning that it must be readable.
  5. CPU must be able to read all forms of memory such as the memory controller, memory bus, and memory module.
  6. The first 64KB of memory must be operational and have the capability to be read and written to and from, and capable of containing the POST code.
  7. I/O bus / controller must be accessible.
  8. I/O bus must be able to write / read from the video subsystem and be able to read all video RAM.
  9. If the Video or other parts of these steps encounters a problem then the system will emit a series of beeps that could let you know what the problem is.
I would disconnect all your devices from your motherboard except for the memory and the video and see if you can power up with the post messages on the screen. Make sure that your memory and your video card are seated securely. If you have 2 memory chips and 1 could be bad, you could remove 1 of them and try your power up again. The reason that we remove the other hardware from your system, is because they could be causing a conflict on the Motherboard.

H57h-am2 beep never stop


A computer will alert you to trouble through beeps and other sounds. If you have a problem with the operating system, the computer gives you different beeps when you start up the computer. You hear the beeps in different scenarios, such as three long beeps or one long and one short beep. These beeps can mean different things depending on what computer model you have. A siren sound on a computer means the central processing unit is overheating. This is true for any computer. When the CPU gets hot, it makes a siren sound warning you that your computer is overheating. At that point, the computer should be turned off to prevent damage.
Open the computer and clean it if you notice a lot of dust inside. You can purchase canned air at most stores. Follow the instructions on the can. Check the instructions in the manual that came with your computer on how to clean the inside of it. If there is a lot of dust, that alone can cause the heat sink to overheat. Verify the CPU heat sink is properly installed and the power is connected. Consult the manufacturer's instructions on how to open your computer and find the heat sink. It should give you instructions on how to check that it is properly installed and connected. You should find it in the middle of the motherboard. Make sure the fan is working. Your CPU will overheat if the fan is not working properly. Refer to the manufacturer's instructions for your computer for instructions to check the fan. Replace it if it is malfunctioning.
WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules make sure that your RAM modules and Cmos battery are securely seated on some motherboards Cmos batteries are soldered in Test all power and data leads that attach from motherboard to your hard drive IDE SATA make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty if its a flat 40 pin ide it will be the first to fail check the graphics card is seated properly with no dust in the socket you might have to remove it to check for dust reinstall it restart your computer the found new hardware wizard should activate a computer needs power and data to travel through every working device and to its continue its cycle and to have and end to function make sure all leads that are attached to your drives dvd\cd and floppy drive have secure make sure the connections and are not faulty or just replace them they could be faulty a computer needs all electric current and computer data to travel to and through every working device and have an end to work properly so any faulty leads will end up with a computer error also check the keyboard for secure dust free connection ps2 and or usb Check you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat Thermal compound is a sticky paste that is placed directly onto the CPU. http://www.hardwaresecrets.com/article/Thermal-Compound-Roundup-February-2012/1490 Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink.

I installed a new motherboard for a Gateway DX4710-05 + windows vista.CPU will not turn on but i do get a continunous bipp sound.Thank you for your help.


In this case do the following steps .
First Remove your computer's RAM and try to switch on the computer . If even after removing the RAM your computer makes the same continus beep sound then just click the RAM properly and insert it properly.
If again you your the same noise then your RAM is faulty.

Cdc-m computer will not come on the on light works case fans comes on but that is all


Do you mean that your computer does not turn on just casing light lit on and Fan runs only? What means new, memory and case?

If just lights on, fan runs but no image on monitor or blank screen, you should hear some kind of sound form inside of the CPU casing. This is called beep code. If you hear continuous beep or 3 same beep with same length, it means your motherboard is missing RAM, just connect it properly. If does not work or stop try a good RAM installing to see the result and plug your this RAM to a working machine that have the same kind of RAM.
If you hear one long beep with two short beep After PC switching on, or Two long beep with one short beep following - that means your Graphics card is not connected properly, or damaged or miss matching. If you do not have any beep code after switching on the machine, your motherboard may not have build in emergency speaker. Try to clear this things first. Please mention details of your computer with model number of your motherboard. Let me know updates.

When i turn my syncmaster 2233 computer, it turns on but it makes a beeping sound alot of times and it won't stop.. I usually fix it by turning the power cable on and off and it will stop the beeping...


Remove the memory (RAM). Clean its contact points by an eraser. Fix it. If it does not work, try using another slot. If it still does not work,replace it with new.

Computer will start beeping and then the monitor goes off and I have to shut down by front button. Sometimes have the same problem starting up. Beeps and will no turn on. This computer has been used...


The beeping sound could be caused by RAM problems or video problems or a BIOS battery.
If the computer has not been used for some time, then some components may not be making proper electrical contact with the motherboard.
Open the computer case and re-seat the RAM (memory) modules and re-seat the expansion cards that are plugged into the expansion slots. The screws need to be removed from the back-plane before the card can be removed and inserted again.
Also reseat the cables to the hard drive and other drives.
The BIOS battery may be flat and if so it needs a replacement lithium battery (the most common type in these computers is 3 volt - CR2032 coin type battery. its 20mm dia) Check before you purchase a new battery. After installing a new battery, the BIOS needs to be configured eg. the Date and Time etc.
Let me know if this fixes your computer, if not then note the error messages and give me the details.

I have an Acer Aspire (and thats as much as I know) that makes a constant beeping sound ... so fast that I cannot even try to detinguish individual beeps to count them. Sometimes this sound does not happen...


Cardinal Rule 1
Dont use ur expensive computer for Games, go to a galeriya
Cardinal Rule 2
Beeping while playing games is a part of the computer's operation...or it can be part of that game.

Some times ur accessories (like ur printer/USB device/mouse etc) is not connected properly...

if the sound is from the PC's speaker then it can be disabled but u will also not get the games sound.

but if it's from your PC's external speaker then u have to live with it or u can mute ur speakers.

Same problem


I would try to replace the PSU and see if that makes your computer boot. Do like a guess and check. If its not the PSU, maybe try a new motherboard. Does the computer not boot, or does it beep when turned on? I hope this helps solve your problem

I recently upraded my computer with an Asrock Penryn1600SLI-110dB motherboard with an Intel CORE 2 DUO E4600 processor. The symptoms are: When I tried to boot for the first time the cpu and case...


Hi,

If you have recently upgraded your motherboard and when you turn it on, there is no display. You could check the jumper setting of your motherboard.

http://download.asrock.com/manual/PENRYN1600SLI-110DB.pdf

Check this site for jumper settings. Download the manual. Go first to page 11 and find clear CMOS jumper. That will be number 17. Then go to page 24 for the correct jumper settings. Jumper should be on the pins 1 and 2. That's the default settings.

If the jumper is set already to 1 and 2. Clear the CMOS by putting the jumper on 2 and 3. It should be off when you are going to set the jumper. This is to make sure that the settings for your motherboard is set to its original settings.

If you are going to clear the CMOS settings, you will have turn the computer on after clearing it and then turn it off again. Put the jumper back to pins 1 and 2. Now make sure that computer is totally off. Uplugged the computer just to make sure when you are doing this.

Note:
To test also the motherboard if it is working, do not connect the other pheriperals such as network card, sound card, and other cards that is not buit-in. Also drives such as Hard Drive and CDROM drives.

Check for beep codes. Short beeps tells you that the Video card is not inserted properly. Long beeps tells you that the memory card is not in place correctly.

Just remove the Video card or Memory card and then place it back again.

Computer should be off as well when doing this.

My computer is not turning on. I just wanted to know if it is a problem with the motherboard or simply the HD. When I press the turn on button, the computer turns on, the cooler works, but i can't see...


Check if you can hear any beep sounds, if you hear a long continuous beep sound, remove the Memory on you Motherboard and clean it with a dry brush then place it back again, be sure you place it as how you remove it, make sure the lock knob on each side of the memory slot firmly locks. If you hear a very short continuous beep sound remove the Video Card then clean it with dry brush and place it back again, make sure it sits tight on the slot.
