Beep Code Explained

Thanks to Transcend Technical Support for this great Brief of understanding beep codes that is found here
This is a long post and it may be truncated at the bottom. If so, use the link above to go to the Transcend web site where these are found




1.General POST (initial system boot) BEEP Codes
If you do not know the BIOS manufacturer, the following will be the general Beep codes:
• 1 Long and 1 Short Beep ?Bad Motherboard
• 1 Short Beep and nothing else happens ?Disk Drive/Video Related Problems
• 1 Long and 2 Short Beeps ?Bad Video Card
• 1 Continuous Beep or Non-stop short Beeps ?Bad Power Supply
• 3 Short Beeps - Bad Memory
2.American Megatrends Inc. (AMI) BEEP Codes
• 1 Beep - Memory refresh timer error.
Reseat the memory, or replace with known good modules.
• 2 Beeps - Parity Error
Reseat the memory, or replace with known good modules.
• 3 Beeps - Main memory read / write test error.
Reseat the memory, or replace with known good modules.
• 4 Beeps - Motherboard timer not operational
• 5 Beeps - Processor Errors
• 6 Beeps - Keyboard controller BAT test error.
• 7 Beeps - General exception error.
• 8 Beeps - Display memory error.
If the system video adapter is an add-in card, replace or reseat the video adapter. If the video adapter is an integrated part of the system board, the board may be faulty.
• 9 Beeps - ROM checksum error
• 10 Beeps - CMOS shutdown register read/write error
• 11 Beeps - Cache Memory Bad

Beeps 4-7, 9-11
Fatal error indicating a serious problem with the system. Consult your system manufacturer.
Before declaring the motherboard beyond all hope, eliminate the possibility of interference by a malfunctioning add-in card. Remove all expansion cards except the video adapter.
?If the beep codes are generated even when all other expansion cards are absent, the motherboard has a serious problem. Consult your system manufacturer.
?If the beep codes are not generated when all other expansion cards are absent, one of the add-in cards is causing the malfunction. Insert the cards back into the system one at a time until the problem happens again. This will reveal the malfunctioning add-in card.
3.Award Bios BEEP Codes
1 Long Beep: Memory problem
Explanation: There is a failure of some sort related to the system memory.
Diagnosis: The first bank of memory probably has a failure of some sort; this is usually just a physical problem such as an incorrectly inserted module, but may also mean a bad memory chip in a module. It is possible that there is a failure related to the motherboard or a system device as well.

• 1 Long, then 2 Short Beeps: Video error
Explanation: The BIOS is unable to access the video system in order to write any error messages to the screen.
Diagnosis: This is usually caused by a problem with the video card, or the memory on the video card. It can also be a motherboard issue.
• 1 Long, then 3 Short Beeps: Video error
Explanation: The BIOS is unable to access the video system in order to write any error messages to the screen.
Diagnosis: This is usually caused by a problem with the video card, or the memory on the video card. It can also be a motherboard issue.
• Continuous Beeping: Memory or video problem
Explanation: The system is producing constant beeping in no specific pattern, or a fast "ringing" sound.
Diagnosis: This is usually caused by a problem with the system memory, or possibly the video card. The memory is more likely--the system complains long and loud if it can't find any usable memory, as there is no way to even start the boot process when this is the case. The motherboard itself could also be the problem.
• Other Beep Codes
Explanation: You have encountered an Award BIOS beep code I do not have documented.
Diagnosis: Award says that any beep patterns other than "one long followed by two short" are likely problems with the system memory. However, of late they have started adding other beep codes to their systems as well.
4.Phoenix BEEP Codes

• 1-1-3
Explanation: Your computer can't read the configuration information stored in the CMOS.
Diagnosis: Replace the motherboard.

• 1-1-4
Explanation: Your BIOS needs to be replaced.

• 1-2-1
Explanation: You have a bad timer chip on the motherboard.
Diagnosis: Replace the motherboard.
• 1-2-2 or 1-2-3 or 1-3-1 or 1-3-3 or 1-3-4 or 1-4-1
Explanation: Motherboards is bad.

Getting F02 error, machine stops part way in & beeps.


Thank you so much for posting your solution of the F02 error code. I was having the same problem and noticed that my clothes smelled like mold and I didn't understand why. Anyway, my husband "cleaned the filter". He found four socks.
Awhile back, I noticed that I was missing a lot of socks. One day I pulled the gray flap in the washer and found around 15 socks! I now check that flap after every wash.

Again, thanks for posting your solution. It was an easy fix and it saved us $$.
