    Do you hear anything like fans spinning? Do any of the lights on the front turn on? There should be 4 lights labeled A-D. What is the status of these lights when you turn it on?

The motherboard could be faulty. Closely inspect the capacitors, especially around the CPU. Capacitors are cylinders that are connected to the motherboard. Most will have a metallic top and are wrapped in black. They should be flat on the top. If they are bloated or have any corrosion, this is definitely the problem. It is common on these models.

Memory upgrade on gx280 beeps on boot but doesn't start. memory beeps 1 234 5 6


When your computer emits beeps when you power on the computer, it's usually means that you have a memory issue. Try re-seating the memory modules and power on the computer. If you have more the one module, insert one at a time and power on the computer. The other issue is if that model supports 4 gig memory.

Keeps beeping when on


Beeps and blinking lights tell the technician what is wrong with the computer. Count the beeps and the pattern of the beeps (3 long beeps, 1 long beep followed by 2 short beeps, etc).

Most times it's something related to the motherboard such as memory or video card.

Did you see anything post on the screen during the boot process?

Check your memory.

Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

Acer computer won't boot has long buzzing noise


The long buzzing sound indicate the nature of the problem. Depending on the manufacture of your bios will determine the problem. With only one long beep you may have memory problem. The computer cannot initiate the boot sequence. Did you add any devices to the computer prior to your problem. if you did undo what you did. Make sure the computer is on, if nothing happens ( no lights, no sound, no fans etc.) the computer has a power failure. Make sure you listen to the beep if it is a numerous beep sequence note it down and check the web for computer beep during boot up.

How to stop the beeping sound


Beeping sounds when you try to boot up? Is your system booting up all the way? Beep sounds help the technician isolate the problem with your computer booting. Beep sounds normally indicate a problem with the memory, cpu, keyboard, fan, motherboard, etc. The number of beeps can be looked up based on the motherboard brand or bios and it will tell what the problem is.

Hi,
If your computer is beeping during the boot up phase then you may have a problem with your laptop. Depending on your system model the beeps will tell you what the problem is and from there you can troubleshoot the problem. I wrote a tech article which goes over computer post issues and beep codes.

Computer dead and beeping


If it beeps and not boot then it is the post routine telling you there is a problem. The post routine is run when you turn the power on to ensure the computer hardware is ok to run. The manufacturer of the bios routine can tell what is wrong by the type, number and duration of the beeps. Look up the code meanings and it will indicate the problem. If this sounds like nonsense to you then give the make and model of your machine and what the beeps sound like. ( beep beep beep delay beep beep beep) etc. and I'll look it up for you.
