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.

Four beeps pc will not bootup


Hi John Jones:

1 long, 3 short beep means >>> Bad video RAM or video card not present. You need to check your RAM. Remove RAM and insert again.

If beeps are of high frequency then CPU is overheated, check you CPU fan.

Hope it works for you.

I have a dell 580 inspiron thats does not turn on..before it turned on but now it just beeps and doesnt follow through with start up.......i had a blue screeen before this ....thanxx


Blue screen could be the windows files getting corrupted due to a virus, file fragmentation or a failing hard drive, overheating cpu or failing memory.
The beeping usually indicates a hardware failure, first open the computer and see it the CPU heatsink is in place properly seated and fan is connected and spinning.
Second with the PC off, remove and reinsert the memory.
These are just a few things to check , most likely the hard drive has failed and needs replacing.
pressing certain keys during bootup can sometimes isolate the issue, but only if the monitor still shows a picture
I hope this helps
Thanks
Roety

I have an hp pavillion a6500f that soon as it is turned on has a constant alarm and is not sending a signal to the monitor. Screen says no signal and then remains black.


If you mean a constant beeping, open the case and see if the CPU fan is running, check also that the heatsink is firmly attached to the board, this noise usually points to a n overheating CPU, if you get no activity on screen,it is because there is no signal being sent to the monitor. Do not operate the computer until you have checked the fan is working, you need to establish if there is power getting to the fan by testing with a multimeter on the motherboard cpu fan pins. If you are getting power, replace the fan, worthwhile removing and regreasing the CPU and making sure it is firmly in place.

If there still is no signal, replace CPU, but also try a different graphics card (faulty video will give 9 beeps).

After that, check the ram is firmly in place.
