One Beep – Failed Memory Refresh Circuit

Solution:Before attempting any other troubleshooting solutions, you must make sure that the BIOS is up to date. If the BIOS is up to date, you should test the RAM modules of your computer. Try using the RAM modules of another working computer, or install new DIMMs. Another possible cause for this problem could be a damaged/defective DMA chip. In the worst case scenario, the memory addressing chips on the motherboard have malfunctioned, which means that you will have to replace the motherboard of your computer.

Two Beeps – Parity Errors in the initial 64 KB of the system memory

Solution:You must make sure that the RAM memory modules are firmly inserted into the corresponding slots on the mainboard. You should replace the installed RAM chips if the problem persists.

Three Beeps – First 64 KB Memory Failure

Solution:Once again you should reseat the RAM modules, making sure that they are firmly inserted. Please replace the RAM modules if the problem persists.

Four Beeps – System Timer Error

Solution:You should switch the computer off, and then remove the RAM modules. After that, you must reinstall the RAM modules, and then test the computer. If the problem persists, you should remove the installed RAM sticks, and then test the computer with memory modules that you know to be functioning correctly. Please replace the motherboard if the problem persists.

Five Beeps – Not specified CPU error

Solution:The CPU of your computer has most likely hit the bells. You should replace the CPU of your computer.

Six Beeps – CPU Protected Mode Failure

Solution:The keyboard controller chip 8042 has malfunctioned. You should clear the CMOS, and then test the machine.

Seven Beeps – CPU Exception Error

Solution:This error indicates that either the CPU or the motherboard is damaged/defective. Both are damaged/defective if you have pulled the short stick.

Eight Beeps – No Video/Graphic Card or Video Memory Error

Solution:You must make sure that the video card is installed correctly. Please replace the installed video card if the problem persists.

Nine Beeps – ROM to BIOS Checksum Mismatch

Solution:This is an indication for a corrupted BIOS. You should try flashing the BIOS.

Ten Beeps – CMOS Memory Failure

Solution:You should reset the CMOS by removing the battery, and then test the computer.

Eleven Beeps – Level 2 Cache Memory Failure

Solution:The L2 Memory Cache is defective. Depending on the architecture of your system you should replace the motherboard or the CPU.

Two Short Beeps – Failed Hardware Test

Solution:This is an indication for a hardware conflict or a defective/damaged component. Please remove any newly installed components, and then test the machine. You should also check all internal components for correct installation and function one by one. In some cases, this problem can be caused by electrical shorts or a dying power supply.

One Long and Two Short Beeps – Video BIOS ROM Checksum Error

Solution:You should check your system for any loose connectors touching the case. You should also reset the BIOS. Another solution is to install the graphics card into another free compatible slot, and then test the computer. Alternatively, you can try starting the computer with the onboard video chip enabled (if your motherboard has one). Please replace the video card if the problem persists.

One Long and Three Short Beeps – Video DAC Failure

Solution:You must make sure that the monitor is properly connected. Please install a different video card that you know to be functioning correctly, and then test the computer.
