I have a bunch of older motherboards and since its raining here, thought I'd check them out before dumping them.

5 boards and none beep on switch on.

I have known good ram, a known good AGP vid card, a known good power supply, a brand new mouse, the keyboard is USB as I cannot find a normal k'board.

What is the possible cause of the no beep on switch on ?

Forgot, the CPU is a known good one too AMD XP 2800+

Thanks, its running bare bones with minimal stuff installed/connected.

However despite there being no sound system, the boards do not get past to lack of the beep. Just wondering what the Beep, or lack of it, means.

So do any of them have speakers in the cases or not? If not then you wont hear anything

The boards are only bench mounted, no cases are involved therefore no speakers.

OK on the no sound, but if a speaker system was used, the single beep must signify something has happened. But what does the single beep I might hear
mean ? I doubt the manufacturer would have the computer beep, just for the heck of it :-)

More than one beep then there is a fault in the Power On Self Test.

But if you have not connected a speaker you won't hear a beep anyway.

Which is what I said

Also what I said in the second post and the lack of a beep can be put down to that fact.

Even if you plug speakers or headphones into the back or the front (if there is no speaker in the case), you wont hear anything. The sound for the case, isnt the same for the sound on the front or the back.

I am talking about the speaker that would be plugged into the motherboard header.

A case speaker in other words.

This is why I said speaker rather than speakers which implies more than one.

I know what youre talking about, but that sounds like what the OP is saying, which I doubt would happen. Because I've just tried it, (plugging headphones into the back), and there was no beep

There are basically 3 types of motherboard speakers - Built in like this (http://img.tomshardware.com/us/2006/05/22/six_975x_enthusiast_motherboards_for_today_and_tom orrow/foxconn_speaker.jpg) or plugged into the Header (http://www.clearpc.ca/catalog/images/speaker.JPG) or One thats in the case Like this (http://www.kids-online.net/learn/click/details/speaker.jpg) -- IF you dont have one of them, you wont hear any beeps at all.
