Motherboard makes a beep

I have recently added a different hard drive to my computer which has windows xp on [previous disk had win98]. Now I was able to boot up successfully the first time and have a good session in windows xp but when I tried to boot again my computer makes a constant beep and doesnt get past the first screen. I guess it is the motherboard ? I DID also change the ram, but im pretty sure it is not that. Everything is plugged in properly and set up correctly.

Can anyone please identify what my problem is ?

many thanks.

what is the make and model of your motherboard?

what you could do is RESEAT the RAM.  reboot the machine.

You can get info of the beeps' meaning for your motherboard from www.bioscentral.com.

If your BIOS is not listed there, take a look at the others 'cause sometimes beep codes are similar between different brands...

Hey, johnkirin, you just copied and pasted the AMI BIOS Beep Codes from http://www.amptron.com/html/bios.beepcodes.html without knowing if Eternal_Student's BIOS is AMI...

That's why I left him the beep codes of many BIOS manufacturers...

Beep codes are dependant on the BIOS manufacturer AND vintage of the BIOS.

try reseating the video card, try other ram, or test the parts on another PC to be sure.
to further troubleshoot, i suggest starting with a minimum : mobo +cpu + 1 ram stick, video card, 1 disk, keyb and mouse. if still no joy, try without keyb, mouse, and disk. this will limit the possible bad parts

For most BIOSes, a long beep at boot signifies a memory error.  Removing RAM, cleaning contacts, and reseating will resolve the problem in most cases.  If it doesn't, try swapping RAM.

Yea its strange because it only happens every now and then ?


I will try and remove/reseat the RAM.

If the problem persists...replace the RAM.

did you try with the minimum?

Run a memory check:

If errors show up, replace the ram. One long beep is nearly always a memory issue.

""only happens every now and then""
Things that are intermittent are generally:
Bad connections.
(Sometimes due to the small amounts of oxidation on the metal in pins or connector. All metals oxidize in air.)
Or an indication something is on it's way out.
The last few years bad caps has been a biggie. http://www.badcaps.net/
People forget things like power supplies and video cards have caps too......
. . Bad cap in PSU or on MoBo -> Bad voltage to RAM -> Bad RAM beeps.

humm, sounds like I need to do some investigation to try and identify precisely what is causing this as it could be several things.

thanks for your time people, i will be back ...

I re-seated the memory and this has solved it.
