No display problem for intel D865GSA board

What are you formatting ? Have you changed the RAM. Does tour system work in its original configuration ? You do not say what the pattern of the beeps is. Before the display disappears, is there a message sent to the screen ?
From the manual

Whenever a recoverable error occurs during POST, the BIOS displays an error message

describing the problem (see Table 53). The BIOS also issues a beep code (one long

tone followed by two short tones) during POST if the video configuration fails (a faulty

video card or no card installed) or if an external ROM module does not properly

checksum to zero.

An external ROM module (for example, a video BIOS) can also issue audible errors,

usually consisting of one long tone followed by a series of short tones. For more

information on the beep codes issued, check the documentation for that external


There are several POST routines that issue a POST terminal error and shut down the

system if they fail. Before shutting down the system, the terminal-error handler issues

a beep code signifying the test point error, writes the error to I/O port 80h, attempts

to initialize the video and writes the error in the upper left corner of the screen (using

both monochrome and color adapters).

If POST completes normally, the BIOS issues one short beep before passing control to
the operating system.

My pc is booting but no display

Did you check your monitor with other system or individually. If it works fine in these conditions then the issue belongs to your pc.
First of all, you have to confirm that is it the problem of VGA itself or the motherboard. For this, you have to see that does system beep when you start it because system with beeps having the error and the beep sound with continuous or 2-3 beeps relate with different issues. I am going to write down the beep conditions.

1 short beep Normal POST - system is ok 2 short beeps POST Error - error code shown on screen No beep Power supply or system board problem Continuous beep Power supply, system board, or keyboard problem Repeating short beeps Power supply or system board problem 1 long, 1 short beep System board problem 1 long, 2 short beeps Display adapter problem (MDA, CGA) 1 long, 3 short beeps Enhanced Graphics Adapter (EGA) 3 long beeps 3270 keyboard card

best of luck!

I have recently built a new PC with an Asus P8H61-M and upon turning the PC on I am recieving no Visual on either of my monitors


If this is the first time to turn you on your computer check first the power supply of your computer if connected to their proper connector. Check your memory if clip properly in there memory slot. If you are using Video Card check it if it is properly connected to the connector. Then connect your VGA connector at the back of your computer when you have video card connect the VGA Cable of you monitor to the video card VGA output if does not have connect it with the onboard VGA output. Then press the power switch if the unit is still no visual in monitor try to search or hear a beeping sound in your computer by its on board buzzer. Find which beep you hear from your computer.

No Beep- No Power, Loose Card, or Short.
One Short Beep- Normal Post,, Computer is OK.
2 Short Beep- POST error, review screen for error code
Continues Beep- No power, Loose Card, or Short
Repeating Short Beep- No Power Loose Card or Short
One Long And Short Beep- Motherboard Issue
One Long and Two Short Beep- Video (mono/CGA Display Circuitry) Issue.
One long and three short beep- Video (EGA) Display Circuitry
Three Long Beep- Keyboard/ Keyboard Card Error
One Beep, Blank or Incorrect Display -Video Display Circuitry

Hi, Do this beeping code for motherboard troubleshooting. First disconnect all memory,external video card, etc only motherboard and power supply. Then power on if you hear continuous beeping means the motherboard working good. Please do this beeping code troubleshooting.
No beeping means Short, No power, Bad CPU/MB, Loose Peripherals. One beeping means Everything is normal and Computer posted fine. Two beeping means POST/CMOS Error. One Long Beep, One Short Beep means Motherboard Problem.
One Long Beep, Two Short Beeps means Video Problem.
One Long Beep, Three Short Beeps means Video problem.
Repeated Long Beeps means memory error.
Continuous Hi-Lo Beeps means CPU Overheating.

In your case, it is a memory problem. It's either one of your RAM has problem if you have 2 slot RAM. Please ensure that you have the right RAM for your board. You can also clean the contacts of your RAM by using eraser.
Below are the most common beep code that being adopted to most BIOS for reporting.
  • short beep - Normal POST(system is OK)
  • Steady short beeps - power supply problem
  • long continuous beep - memory failure
  • Steady long beeps - power supply problem

I have mb-msi2000-815e pro ver1, it is constantly beeping. change the memories,agp,, but it still continues.what could be wrong/

1.Your first step is to look at the information about the meaning of the beeping codes. Beep codes are important and useful tools when troubleshooting booting issues. When you turn on your computer system, it is called POST (Power On Self Test).

2.No beep is usually a power problem that can be related to the power supply, motherboard or both. Always check your battery power before thinking there is a bigger problem.

3.One beep is a normal POST. That means everything is fine.

Two, Three, or Four short beeps are normally about the memory of the machine. If there is a problem with one of your memory chips you should get beeps of different combinations in this area. If you get two or three short beeps, one or both of your memory chips could be in trouble.

4.Five beeps point toward motherboard or CPU problems. Make sure your memory and video card are seated properly. Try removing them and putting them back in, only if you are comfortable with computers.

Six, seven and eight beeps.

Eight beeps indicate problems with your video card. Six or Seven are CPU, or a bad chip on the motherboard.

Nine beeps mean the BIOS is bad. Replace the motherboard.

Ten beeps means the problem is in the CMOS. All chips need to be replaced.

5.Eleven beeps are related in the cache of the mother board and this means that the motherboard needs replaced.

One long and three short beeps mean that it is related to a loose memory chip. Try reseating it.

One long and eight short beeps means that the video cards needs reseated.

6.I hope that this list of beep codes will help settle the panic you feel when your computer is sick. If all fails, Then you inform me

Sounds like the CPU may not be seated properly, did you remove the processor when you replaced the cooler (Heatsync I assume you mean)?
Try powering down and unplugging. removing the heat sync removing the processor. Re-seating the processor making sure it falls into place. then re add the thermal paste(if needed) and heat sync. Check the memory and video card to make sure they are firmly in and then power back on and see if it will boot.
Another thing you can do is check your motherboards manual or website and there is a description of "beep codes" that you can listen for yours and see exactly what its telling you is wrong.
Good luck

Problem with the Gigabyte GA-EP43-UD3L Motherboard Continuous short beeps on power up.Then shuts down

Trying to help you, please clarify me if the beeps are short or long ones, or some (how many) shor followed by some (how many) long ones. Don't worry, leaving the computer at "beeping mode" won't hurt it. Sorry for the details but these kind of codes identify if it's a motherboard, or CPU, or memory error.

Waiting clarification, don't hesitate to post.

Thanks and regards

My bios speaker will beep on startup but nothing more. What avenue should I approach to get past this part of startup?

First you need to know which BIOS you have and how many beeps it is producing... these beeps are the POST - Power On Self Test. They tell us if there are problems such as missing keyboard, video card not working, memory faults etc...

Then you need to go to the appropriate BIOS site and see what the number of beeps mean.

If it is a single beep - it means all is well...
As you are not getting anything more you should check to see if the Hard Drive (HD) light flashes - if so - the HD is probably operating ok and loading your system but there is either a problem with your monitor or video card... borrow another monitor and see if that helps...

But it all depends on the number of beeps you get and what kind - long and short beeps (like morse code).

If this helped you at all please vote!
