    BIOS Beep Codes

    <img src=/S/hello.gif border=0 alt=hello width=25 height=29> Loungers

    OK if there are no BIOS Beep Codes, that means one of tow things:

    1) The system boots and you are OK.

    2) The CPU is damaged, and is unable to perform the POST.

    Anything else?

    Re: BIOS Beep Codes

    Normally upon a cold boot,,one beep means everything is cool. No beeps means the internal speaker isn't working. <img src=/S/grin.gif border=0 alt=grin width=15 height=15> From there,,two beeps and up can mean different things for different Bois's.

    3) PSU fried

    4) M/B faulty

    5) speaker disconnected

    etc

    It can't be that the speaker is bad, or damaged, or disconnected, I do get a chirp, not a beep, but a chirp like two parts of sandpaper rubbing each other, and nothing else. Sorry <img src=/S/sorry.gif border=0 alt=sorry width=15 height=15>I should have said that in my post.

    The guy who built the PC is looking at it, but he tells me that this is a Video card issue. I say No!!! It must be something else, because there are no beeps.

    I think it is the CPU, MoBo or RAM. I say these in this order because:

    1) The PC is in a hot room, and close to the radiator. CPU is susceptible to heat.
    2) The PC was working fine until someone turned it on and left it on. So I guess the heat built-up and crashed the CPU.
    3) The Power supply is getting juice, but after that, nothing. I wanted to open the case, and see if there are any LEDs in the MoBo that are lit, but I couldn't figure out if the MoBo is the type that has any. Its an eMachine, so I thought maybe they went with the lowest bidder. Plus the LEDs on the NIC are on, so I guess the MoBo is getting to do its thing.

    As it takes a CPU to run the POSTest, I chose the CPU to be first. The chirp is not a CPU sound. MoBo can affect the CPU, but I can't tell with a bad CPU anyway. I think RAM is more resilient than any other movable component in the PC, plus POST would not need RAM to start, but definitely a CPU.

    Am I OK in my analysis, or should I get a <img src=/S/newbrain.gif border=0 alt=newbrain width=21 height=22>?

    Thanks for sharing your ideas.

    What is a PSU, Power Supply Unit? All things get juice when I turn the PC on, fan on the Power Supply Unit, the NIC LEDs, CD-ROM LED lights up, and so on.

    MoBo? Hum!!! I need an OK CPU first do make sure if that is the case, and I am afraid of getting a new one and have the MoBo damage it again, but what can I do to make that determination?

    It can't be that the speaker is bad, or damaged, or disconnected, I do get a chirp, not a beep, but a chirp like two parts of sandpaper rubbing each other, and nothing else. Sorry <img src=/S/sorry.gif border=0 alt=sorry width=15 height=15>I should have said that in my post.

    Re: BIOS Beep Codes

    Have you tried unplugging all the drives, etc and see if it will post? Start with only CPU, RAM, and MOBO. If it does, plug them in one by one until you get to the problem again. Yes, you will need RAM to post, all motherboards I have used will not post without RAM installed. Someone correct me if I'm wrong!

    It might very well be a video problem if the mobo has on board video. This is one of the reasons I stay away from motherboards with on board video, and generally pick one with an AGP slot.

    Process of elimination, Yes I did that all the way down to MoBo, CPU and RAM. BUT <img src=/S/noevil.gif border=0 alt=noevil width=25 height=17> tell me what do you think it might be a video problem?

    I know that video is one of the very first things the POST will test. Now if it works, then OK, and when it fails, you should get BIOS POST beeps.

    Say you are using AMI BIOS, and referring to the page I linked to in my original post, this will mean you have to hear a 1 long beep, with 2 short beeps.

    BUT <img src=/S/confused.gif border=0 alt=confused width=15 height=20> if it beeps 5 beeps, that means the CPU is down? <img src=/S/hairout.gif border=0 alt=hairout width=31 height=23> I was always under the impression that POST needs a CPU to run? I guess not... <img src=/S/igiveup.gif border=0 alt=igiveup width=31 height=23>

    I will be looking at a much more detailed information about how POST runs. Maybe it only needs the MoBo components, which means that if there are no Beeps, it could be the MoBo <img src=/S/hushmouth.gif border=0 alt=hushmouth width=16 height=16>

    Thanks for your input.

    Re: BIOS Beep Codes

    I didn't see any references in the other post to this question,,so I'm gonna ask. What exactly is it doing when you power up? Do you see anything on the screen? Can you get into BIOS? Is your monitor showing it trying to post. MAybe eaiser just to tell me what happens when you push the power button.

    Re: BIOS Beep Codes

    Cowboy's question about what you see on the screen might be the clue. Most times, it's an educated guess, and sometimes you have to resort to switching out parts. Keep in mind that you can build a pretty decent PC for about $400 to $500 or less depending on what you want. In the pc I have now, continuous beeps means faulty ram. You mentioned something about 5 beeps...depends on the bios what the beeps mean. I think if the CPU is fried, you have a dead box-no beeps and certainly no post, but I'm not entirely sure about no beeps.

    OK let me take it step by step:

    1) <<< What exactly is it doing when you power up? >>>

    All I get is a chirping sound from the speaker. One chirp, like sandpaper rubbing, no other reaction. That is it. The obviouse is that the Power supply fan is going, the CD-ROM LED flicker a bit, I am not sure of the Floppy's LED, and I am not sure of the keyboard LEDs as well.

    2) <<< Do you see anything on the screen? >>>

    No. Nothing is on the screen. The screen LED, flickers to amber after a while. Thus its a signal that the video card is not sending anything to it.

    3) <<< Can you get into BIOS? >>>

    I did not try simply because I did not see any indication that POST has finished and now the PC is booting. I will try and report back. I will observe all these answers to these questions.

    4) <<< Is your monitor showing it trying to post. >>>

    If you mean instructions on the screen, no, there is nothing on the screen and the monitor LED goes to amber when powered up.

    These are the indications I am going by to dignose the PC, as faliure of the CPU. But reading about POST, it seems to me that you don't even need a CPU to run POST, or you may need specific functions of the CPU.

    Re: BIOS Beep Codes

    Not to step on Cowboy's feet, but the first thing I would try is a video card, because you cannot even see if it has posted. Not likely that an eMachines factory box will support AGP, but it might be worth a look to see if there is an AGP slot right above the PCI slots (better to get an AGP card if it supports one because AGP cards do not use as many system resources). If no AGP slot, try a PCI card. HTH!

    Re: BIOS Beep Codes

    Mike has a good point about the Video Card,,,but from what I am reading in your post,,,it could also be something not seated or connected properly,, it also could be a faulty Power Supply. But I have to agree with Mike,,,,I would try another Video Card before you do anything else,,and if it won't bootup after that,,I would check all connections and then the Power Supply.
    I build computers and I have seen this before,,and it usually one of three things,,,Something Is Not Seated Or Connected Properly,,Bad Video Card or Power Supply,,and in that ORDER. Also make sure your BIOS settings are correct for your Memory and Video Card.

    Re: BIOS Beep Codes

    The "Chirping" is power going to a speaker and then quickly going away. In other words you flicked the light switch on and off so quick that the light (speaker in this case) could not go to 75 watts you only saw 20 watts for a brief time.
    For BIOS you need M-Board, RAM, CPU and Video all powered. Based on what I see here the PSU may be giving power but not under a load, as soon as something (in this case the components) start to draw amperage (power). Some capacitor or relay is having a problem.

    Interesting observation. <img src=/S/scratch.gif border=0 alt=scratch width=25 height=29> I will need to find my tester and read its manual <img src=/S/read.gif border=0 alt=read width=19 height=33> and see if I can detect any power failure on the Power supply.

    But it will not have the load it usually have? <img src=/S/confused.gif border=0 alt=confused width=15 height=20> Will the test be valid?

    Thanks again.

    Wow!!! I am feeling like a puttz <img src=/S/bagged.gif border=0 alt=bagged width=22 height=22>

    You are right, maybe it is posting but there is a video problem.

    AND

    yes there is a brown AGP slot, and the video card is not in it... <img src=/S/scratch.gif border=0 alt=scratch width=25 height=29>

    I will need to do my homework on diagnosing hardware problems...

    The obvious may not be the situation.
