Troubleshooting The System Overall | Troubleshooting BIOS Beep Codes | AMI BIOS ] 6 Beeps: Keyboard controller / gate A20 failure
Explanation: The keyboard controller is a chip on the motherboard that communicates with your keyboard. It parity circuit failure also controls the A20 gate that provides access to the high memory area (HMA). This component is indicating a failure. Diagnosis: This is usually a problem with either the keyboard or the motherboard. Recommendation: Troubleshooting the keyboard is relatively easy; try that first. Troubleshoot the keyboard controller. Troubleshoot as a motherboard failure.

your computer is running. If your computer still starts up the BIOS information is displayed briefly on the screen. For those that post error codes list can't read that fast you can find out the BIOS version while your computer is running. 1. Click on Start and then Run. 2. In the text box in the Run window, type msinfo32 and click OK. http://www.pcguide.com/ts/x/sys/beep/amiB6-c.html This will open the System Information program. 3. When System Information opens, it defaults to the System Summary. 4. On the right side of the program, locate the BIOSVersion/Date information. If your computer will not start up you can remove the side panel of your computer and locate the BIOS chip for manufacturer information or you can go to the computer manufacturer's website with your make and model number and find out more information http://www.pcapprentice.com/computer%20beep%20codes.htm about your version of bios and the relevant computer beep codes there. AMI BIOS computer beep codes 1 Beep Memory refresh timer error. The solution is often replacing the RAM. 2 Beeps Parity error in base memory. This is a problem with the first 64KB memory block in your RAM. The solution is usually to replace the memory. 3 Beeps Base memory read/write test error. Replacing the RAM usually solves this. 4 Beeps Motherboard Timer error. Hardware failure within an expansion card or the motherboard itself could be the cause. 5 Beeps Processor error. A damaged expansion card, the CPU or the motherboard could be at fault. 6 Beeps 8042 Gate A20 test error. Usually an expansion card has failed or the motherboard itself. 7 Beeps General exception error. Usually caused by a faulty expansion card, a motherboard hardware issue, or a damaged CPU. The fix is usually to replace the faulty component. 8 Beeps Error with the display memory. Usually a failed video card causes this error. Replacing the video card fixes this. 9 Beeps AMIBIOS ROM checksum error. This error points to a problem with the BIOS chip on the motherboard itself. This kind of problem is usually fixed by replacing the motherboard. 10 Beeps CMOS shutdown register read/write error. This is usually caused by a hardware issue

Experience Worklog Contact Personal Blog [ro] Misc BIOS Beep POST Codes by silviu•September 11, 2010•0 Comments Ever found yourself standing next to a PC that won't boot and emits all kinds of short or long beeps. Me too. Here's a list http://www.sgvulcan.com/2010/09/11/bios-beep-post-codes/ of what these beeps might mean. Please note that because motherboard manufacturers often modify the code http://www.voxtechnologies.com/bios_error_beeps___messages.htm bought from these companies the beeps might mean something else. AWARD Beeps Error Message Description 1long, 2 short Video adapter error Either video adapter is bad or is not seated properly. Also, check to ensure the monitor cable is connected properly. Repeating (endless loop) Memory error Check for improperly seated or missing memory. 1long, 3short No video card or bad video RAM Reseat or beep codes replace the video card. High frequency beeeps while running Overheated CPU Check the CPU fan for proper operation. Check the case for proper air flow. Repeating High/Low CPU Either the CPU is not seated properly or the CPU is damaged. May also be due to excess heat. Check the CPU fan or BIOS settings for proper fan speed.

Reseat the memory SIMMs. If the system still beeps, replace the memory. 2 Parity Error Parity error in the base memory (the first 64 KB block) of memory. Reseat the memory SIMMs. If the system still beeps, replace the memory. 3 Base 64 KB Memory Failure Memory failure in first 64 KB. Reseat the memory SIMMs. If the system still beeps, replace the memory. 4 Timer Not Operational A memory failure in the first 64 KB of memory, or Timer 1 is not functioning. The motherboard must be replaced. 5 Processor error 8042 - Gate A20 Failure The CPU generated an error. The motherboard must be replaced. 6 8042 - Gate A20 Failure Processor Exception Interrupt Error Cannot switch to protected mode. Try a different keyboard, or replace the keyboard fuse, if the keyboard has one. 7 Processor Exception Interrupt Error The CPU on the CPU Card generated an exception interrupt. The motherboard must be replaced. 8 Display Memory Read/Write Error The system video adapter
