Hi, Past experiences with different models of Asus of this type of problem indicates BIOS problem. I have not come across the same symptoms with ECS, Intel, MSI, Gigabyte or others but once in a Samsung. The beeping sound is actually up down (like old ambulance siren). I have tried some correctives measures with varying results: 1. Clean the motherboard with a strong solvent, hot air dry with particular attention to the BIOS chip; 2. Resolder the bottom side of the motherboard particularly the chip holder of the BIOS; and/or 3. Flash the BIOS chip using an identical motherboard or an EPROM programmer. If all else fails, am afraid you have to replace your motherboard. Good luck and pls post back how things turn up or if you need further information. Kind regards.
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
