Re: computer will not boot

The code A6 indicates bad memory. If it is new take it back or replaced under warranty.Most memory manufacturers have a lifetime warranty.

If it came with the new computer, take the whole computer back and get it replaced under warranty.
Please let me know how you make out.

Computer POST and beep codes
The computer power on self test (POST) will test your computer to make sure it can boot properly(test hardware and sys requirements), once it does the computer will then finish the boot process. Normally, if your computer passes the POST test it will beep once or possibly twice. If the computer fails the POST then it will either not beep at all or generate a beep code.

The beep code you receive can indicate what may be wrong with your computer. The beep codes vary depending on your motherboard BIOS manufacturer(AMI, Award, Phoenix). You can find what BIOS you are using by paying attention to the BIOS screen when your computer boots up. It should tell you what brand BIOS.

You can usually find the meaning of your beep code by doing a simple google search i.e "phoenix beep codes". Below, I have provided links to sites which go over beep codes and their respective meaning.

Abit as8 post codes 21

Hello here is the homepage:

Post code 21, is a memory/ chipset problem.

It could be a problem with a ram module, or a Pci sound card or a graphic card. or powersupply.

Try to remove any add in cards, and try to boot with only one stick of ram.

Good luck

Twice beep sound is coming. Booting is not happening for my p4p800 mx/s board

Hello !
If you check out ASUS support, you will find this troubleshooter for the motherboard not booting :
1. Please clear CMOS.
2. Please take out your memory cards and video card, try to clean their golden connectors with a rubber, then reseat them back.
3. Please take the CPU cooler out, add some thermal paste to the CPU surface, then reseat the cooler back and keep the cooler tightly installed.
4. Please keep the necessary components(CPU, one memory) onboard for a test.
Finally, we would recommend you to replace a BIOS battery to have a test.
Also, by looking over beep codes I have found for AMI BIOS these problems for the 2 short beeps :
1. Memory parity error (Description : A memory parity error has occured in the first 64 KB of RAM. The RAM IC is probably bad).
2. POST fail (Description : One of the hardware tests have failed).
If you have done those and it still doesn't boot, let me know I'll try to find other solutions.
All the best !

My MSI P6NGM-based system stopped working. On


Parity is a memory ( Ram problem ) try removing 1 Stick. or changing it into another slot. if you suspect Bios. remove power cable. locate The CMOS Battery. remove for 10-15 seconds, And replace it. this will reset the bios to it,s default settings. you,ll know if your asked on boot-up to run setup to change time/date.

When i swithch on the monitor is blank and there are two short beeps. Also the numbers 1 2 and 3 are lit in the tower front

The two short beeps are probably a POST (Power On Self Test) code. These have been in use since the first PC was manufactured by IBM, and other manufacturers decided to let IBM's POST codes be the standard for PC clones for several years. AMI, a BIOS chip manufacturer later came up with their own. Since then other manufacturers have strayed form the IBM fold, also.

For more info, go to <a href=""></a>.

Your 2 beeps in IBM POST code mean: POST error, see code on screen (code 123 means "system board error"). Not a lot of help!

Your 2 beeps in AMI BIOS POST code means a Base Memory Parity Error (bad memory chip in lower 64k of RAM).

The 123 display on the tower may NOT be the IBM POST error code, but something else. As reets-tech implies, you probably will only be able to get a definitive interpretation from your computer's manufacturer or one of their authorized repair facilities (if any). Good luck!

3 long beep

The Intel motherboard D845GLVA can only run up to 2GB of 184-pin, 2.5 V, DDR266/200 MHz SDRAM. Test the system by inserting only one stick of memory into slot 1 which is closest to the CPU. Boot system & listen for beep code. If no change remove memory & insert into slot 2 & boot system. Listen for beep code. The Intel D845GLVA MB uses the AMI bios. There is no code to match your 3 long beeps.
Click on the link below, scroll down to AMI;

However, you mentioned you loose display when you here the 3 beeps. This is common when a video card is not connected correctly or does not have enough power. Since your MB uses a built-in video card it is very possible that the video controller,
Intel 82845GL Graphics and Memory Controller is going. You can test this theory by buying a PCI video card & installing it into any one of the three PCI slots on the MB. You will not need to enter the MB bios to make any changes. The MB will auto detect the video in the PCI slot & use it over the built -in video. See page 15 in your manual: PCI Auto Configuration.
If you need the manual for your MB you can download it from Intel.
Click on the link;*+XP+Home+Edition&lang=eng&strOSs=45&submit=Go%21

Any one of the video cards listed on the next link will run in your system;

Good luck!

Hardware Malfunction

Hi there.
Parity check is usually to do with memory due to dust, take the memory out clean the contacts with a soft, clean dry paintbrush and the slots too free of dust, re-seat the memory and your problem should be solved.
post back if you need any more advice.

Good luck and thanks for using FixYa!!
