No post at start up, Giving display beep code

Question: No post at start up, Giving display beep code

What started as repairing a friends computer eventually turned into a complete overhaul.Here is the story, He was playing eq2 one day, happy as a clam, and suddenly his comp died. After that, it just would not start up.He broght it to me, and I replaced the psu, same issue, replaced the mobo, and nada.... after he thought about it, he decided that he wants to upgrade anyway, so asked me to get him new parts and build him a new system...So, here is the listAsus M2N32 sli am2 moboAmd Fx-62 cpu2 gigs of ddr2 ram (a-bit, or a-byte or something, it was listed in the mobo manual as being compatable)antec 900 gaming case (which has a mini tornado inside.... I mean wow lol)At first I used his exisiting graphics card... Put it together and BAM same problem. The fans would twitch, but nothing powered up.... After I recovered from the head trauma of banging it against the wall, I took the graphics card out, and everything, started working... So I deduced that after all that, it turned out to be the graphics card. So I replaced with:Nvidia 7950NOW everything powers up, but no display, and the beep code gives me the 1 long, and 2 short beeps, which tells me that it can't display.I have checked, rechecked, reseated. I switched his graphics card with mine, to see if it was a defective card, and his works in my computer, but mine still had the same issue in his.The only thing I didn't replace yet is the Hard drive.Any suggestions?

Preferred Solution: No post at start up, Giving display beep code

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: No post at start up, Giving display beep code

Some motherboards hold beep codes even after the problem is fixed. One possible solution is to remove the battery, clearing the CMOS, then replacing it.

Hello!! I own a full tower gaming computer, was working fine the other day, then the next morning when I turned it on, it didn't boot. There was power in the computer, but the monitors weren't picking up a signal, it was also giving off a beep code. The beep was 1 long 2 short over and over, I think it might be to do with my gpu, but I ordered a new gpu to test and that did nothing. I noticed a chip on said new gpu was burned out after use in the PC though, could the motherboard be causing the GPU to burn out?

Thank you in advance

P.S I've also tried seperate ram and that didn't change a thing

Upon booting, the PC gives a BIOS beep code of 3.3, i.e. 3 long beeps followed by 3 short beeps which is repeated 5 times before the PC successfully boots. From what I can find, this translates to "The embedded controller has timed out waiting for BIOS to return from graphics initialization". So a possible issue with the graphics card? The PC behaves as normal but there has been an instance where the display has cut out completely, giving an entirely blank screen, with no mouse or anything. I was only watching some Netflix when the screen cut out. It appears to not be an issue with the monitor as while the screen was blank I was still access the monitor's on screen controls and I've been using the same monitor for a while with another system. I couldn't really find any other people with this same issue and therefore was unable to find any possible solutions. I must also note that this is a new PC. It only began giving the beep code on the second day of use which was yesterday on the 26/12. Any suggestions are appreciated

My Pc broke down today, it does not boot, no post, fans slightly turn on but then off and no beep code even without ram. I have tried with a new power supply so that is not the problem. I have also tried to start with just the mobo CPU and psu, but no luck. How do I know if I have a faulty motherboard or if it?s even the CPU?
Thanks in advance

I recently bought two government surplus M58 desktops (7360-P52).  Core 2 Duo E7500 + 2 x 2GB PC3-8500 + 250GB Seagate drive + Win 7 Pro installed. Both machines work without problems after boot.  Before booting, though, I count 38 short beeps at POST in quick succession on both of them. This isn't a documented code anywhere that I can find. I have tried swapping DIMMs and DIMM locations.  I have dropped in 1GB DIMMs instead.  I have changed the button battery.  Unplugged the DVD drive.  Unplugged the hard drive.  The fans seem to be running fine. I would keep swapping parts if it wasn't 38 beeps on both. I would be very grateful for a clue.

Morning all

I have a HP/Compaq D220 MT computer that is giving an 8 beep code over and over at startup. I have no video no nothing on screen. When i remove the memory it gives the correct memory beep error (3) i have removed all periferals and removed power and data cables from all devices except the MB. HP is SLOOOOOOW at trying to get Tech Support and their "live help" is kinda useless if your not using the computer that has the problem ( if i can use the computer that has the problem then why do i need LIVE HELP LOL) Any Help would be greatly appreciated.

I have a problem with 5 beeps sound, and after replacing the CMOS battery, the beeps are still here...
So I'm not concerned so far why it still beeps, but i would like to know how to disable this sounds, at least temporary... because its annoying when i use headphones?
I can confirm that when i mute all sounds, using the keyboard button the beeps are also muted. How can i do the same thing but only for the 5 beeps?
Thanks in advance!

Answer:Disable (post?) beep code sounds

jovan.meshkovhow to disable this sounds, at least temporary
Hello. Try this. It's for turning off system beeps. I think it will turn off the POST beeps.
1. Open the Device Manager. 2. In the View menu at the top, click “Show hidden devices”.3. Scroll down to “Non-Plug and Play Drivers” and  expand (click the + sign).4. Double click “Beep”. 5. Click the “Driver Tab” and change “Startup Type” to “Disabled”.6. Restart.
jovan.meshkovSo I'm not concerned so far why it still beeps
Until the issue with the laptop is resolved, I would be extra careful to keep a separate backup of all data.

This particular computer is using Pheonix Bios. During POST, I am getting 1 long, 2 short beeps as well as no feedback to the monitor which indicates a graphics card failure presumably, but I am suspicious of a motherboard failure as well.I disconnected everything except mobo, proc,1 stick of ram, and gpu and got the same code. Then, I went through all the ram slots (there are 4 on this mobo), and found 2 slots that give a different code which is infinitely repeating long beep. With the gpu disconnected I get the same 1 long 2 short beeps. Based on this, I'm not sure if I can condemn the gpu or not because of the problems I seem to be having with the motherboard as well. Seems like it may be both the gpu and the mobo. I may be able to borrow a compatible known good gpu, but I don't want to risk frying it if the problem is in the mobo itself.Any further tests or suggestions would be much appreciated.P.S. Powersupply is also a known good.

I have a T400 not on warranty. I just purchased it a week ago so I know very little about the system. Pre problem: Lap top worked fine. I placed it in hibernation for the first time and walked a block. I fell in that time. The fall was more jarring to me than the computer but I do think it could be the cause of the problem. When I got home - it would not come out of hibernation so I rebooted. The z light came on and the beep code of 1-1-1-1 occurred. Things I have tried: 1) confirmed the harddrive was still good - placed it in another T400 I have it booted no problem.2) removed the RAM - beep code changed to 1-3-3-1 longer pause 1-1-1-13) replaced the RAM4) Did the Lenovo Hard reset ( unplug, remove battery, hold down power key for 10 seconds tap 15 times put back the battery and plug lap top in.) still beep code 1-1-1-15) searched Lenovo Beep codes - this is not 4 sets of 4 beeps it is just one set of 4 short beeps with pauses.6) removed the cmoss battery and put it back in.7) Hooking up an external monitor.8) holding down the FN key9) holding down the Fn Key and the F1 key10) holding down the F1 key11) pressing the thinkvantage button.12) Pulling apart lap top and disconnecting the modem and trying to reboot. I looked over the motherboard it does not look cracked in any way.

Answer:T400 Model# 2489 Will not post. Beep code 1-1-1-1 and Z light on.

2489 isn't a valid model.  Do you mean 2789?  In any case, your diagnostic procedure sounds correct.  I assume the main battery was out and the machine was unplugged when the CMOS battery was pulled. (either can supply power to the cmos)  One more thing:  I have found that the cmos battery needs to be out for longer than you would expect on the newer models.  I pull it out for the whole time I go through the "pushing the power button" thing.  The only other thing I would do if I had it here is to hook up a contraption that usually can read the post codes to tell where it failed.

Hello all,

I built a computer for my mom 6 months ago, and now it won't POST or show display or any beep codes. The last thing it showed on the display was the info when it POST's and then went blank.

The mobo is a GIGABYTE GA-7VT600P-RZ Socket A (Socket 462) VIA KT600 ATX AMD with 1 gig processor, with corsair memory (512) value select pc3200.

The power supply came with the case and I don't know the brand off hand.

I have not looked at the system yet, but I will check memory, video card and cables to make sure they are secure and reseat, and check power supply voltages. I'm pretty sure the monitor is good.

If there are any other things I can check, any help would be much appreciated.

Hi, this is my first time posting on this site and I need help. I have built everyone in the house's computer and if something goes wrong I can usually figure it otilout and fix the problem. Not this time, I'm about to fix it with a hammer.
My system- ASUS P4SD-LA Stingray mobo with a pentium4 CPU, 2Gb RAM, Maxtor 40Gb SATA HD, ATI 9800XT video card,M-audio Audiophile 24/96 sound card and 500w PSU running Windows XP.
So, everything was running fine until last week. I normally don't shut my system all the way off, I just put it in hibernate but for some reason I turned it all of the way off. The next morning when I went to turn it on it wouldn't boot into XP and gave me a missing file error message ( I forget which one). I ended up having to do a system repair with the install disk starting from XP SP1. When I got to the SP3 disk my CD-ROM drive crapped out on me and I had to swap it for a different one, got repair install finished and when I rebooted it seemed to be OK except I couldn't connect to my network at all. The next time I booted it up I had no display on my monitor, all of the system fans were on, I could hear the HD, but no screen.
I'll try to make this long story shorter, this is what I've tried so far (not necessarily in this order)-
removed all cards, cables, etc. and cleaned the contacts, put them back in.
It ran fine for 1 day, then just a black screen again.

Very happy with my new machine. Thought I'd pop my old pcie nvidia gtx card in for a bit of a boost. I uninstalled the old cards drivers and software, powered off and just about managed to squeeze it into its slot. I also changed the psu as the stock one probably not powerful enough and no pci 6 pin power cable.When I power it up, all the fans spin, and the HD clicks away a little, then a slight pause before 3 long low beeps and 3 short high beeps with corresponding power led flashes, this repeats 3 or 4 times before it becomes a very expensive desk fan.If i swap the original card back in, all is well.Thinking it may be a faulty card, I've bought another pci express GTX 550 ti (yeah well, it's all I need and could afford)Same story with that card.Now, is it possible i have two faulty video cards? They are both over 5 years old.A faulty psu? I have tried a hard drive power adapter, as well as the proper pci power cable.Or have I missed an important step in installation? I've never had any problems swapping cards out before.I've tried resetting the bios via the jumpers and the holding down the power switch for 15 seconds thing.Can't find anything on the beep code, hp site is vague, others don't seem to have what I'm looking for.

Before you do anything else reseat your RAM modules. If this doesn't fix it go back to basics - disconnect everything from your mobo except graphics card, power and RAM does it boot the monitor on start up? If not and you only have 1 ram module fitted beg or borrow another and try that - if you have 2 ram modules try them one at a time on their own. Post back when done and adviseRgds

As of this morning my computer will not start. I've had the components besides the case for a year and a half, and there haven't been any major issues with this build before. Its a pretty standard rig, heres the info:
ASrock 870 extreme 3 mobo
4GB Kingston RAM
AMD Phenom x4 Processor
ASUS graphics card (I got it used from a friend so I can't remember which model it is)
1TB Seagate HDD

However, today when I went to start it it would not even run post and there were no error beeps on startup to indicate any issues, however all of the fans spin up properly.

I tested to see if the ram or graphics card were the problem, but even with each of them removed there were still no error beeps or post, which leads me to believe that it is the mobo which is causing the issue. I'm not sure though, since I've never had a problem remotely like this before.

I would greatly appreciate any additional information or input anyone has pertaining to the situation. Thank you for your help.

Answer:PC will not start, no post, no error beep codes.

I suggest completely disassembling the build, removing everything except the PS, motherboard, and CPU/Heatsink.
If you do not get an error beep code with just those components then you know it is one of those 3.

Also, before or after that test, perform a ClearCMOS procedure, just to be sure there is not a lock-up in the BIOS.

I've seen like a million other threads for this particular problem with just about every kind of possible solution there could be. However, as no two computers can be identical, I'd give it a shot and get some help on this one.

After attempting to resume Win7 from Sleep, none of my displays awoke so I shut the system down, checked all cables and leads for the monitors. As it were, no issues.

I booted my PC to be presented with a whole lot of ... Nothing. All drives and fans were functioning, my DVDROM did it's little check for CDs, all the normal crap, only it neither woke up, or brought me to GRUB.

Thus far, I've reset CMOS, done bare bones booting, tried my GPU, HDDs and PSU in my several other self built machines. No problems, no drama.

I'm yet to test my CPU and RAM in another machine, as I don't actually have another capable of it at present. I'm also quite unsure on whether my speakers works or no, I've tried several with no beep codes.

As of right now, it's still set up for bare bones booting. I should also mention that the power button needs to be held to kill the system on an attempted boot.

Any ideas, or help would be appreciated, specs will be posted below.

Answer:No display, beep code or boot after Sleep Mode

EDIT3: As it so happens... It seems to be booting successfully now. I've put all hardware, cables and leads back to their original locations and it boots, or so I assume. The activity indicator now does it's job when the PC is booted, and my reset button works once again. I still require to hold the power button to kill my system, but I believe that is due to ASUS TurboKey (Makes power button auto overclock PC on-the-fly). Displays still don't function. Going to attempt my alternative GPU and will re-edit with results. USB mouse and keyboard also appear to not function, which is normal at certain stages of my boot up. The only times they function during boot is at BIOS, GRUB and once I've launched my OS. Still, could be a potential problem indicator.

EDIT4: No change. Main, alternative and onboard, it doesn't matter what, it doesn't display anything.

EDIT5: The CPU and RAM are fully functioning in another system, it would appear either the BIOS isn't receiving the power up signal or it's damaged/corrupted. Unfortunately, I cannot flash the BIOS or restore it. Problem solved.. Sort of. Going to replace it, but keep it incase either myself or someone else stumbles upon a possible solution. I'd like to request this thread stays open incase anyone has ideas, or I find the solution so it can be archived at least. Thanks for, well, allowing me to brain storm.

After this I tried replacing the CMOS battery with a new one and I still got no signal. I even tried connecting the video cables to the motherboard instead of the GPU. I researched the beep code; "An error was encountered in the video BIOS ROM, or a horizontal retrace failure has been encountered." How can this be fixed?

Answer:No Display When Powering On Computer. Beep Code [1long,2short]

Where are you sticking the cable to the motherboard and not gpu? Is this the board listed in your specs on here because that has no onboard video on it and you must use a add-in gpu. If your VBIOS is messed up on the 970 it might be rma time.

My problem is that my PC won’t start up. First, the monitor sets on (green light) but then immediately switches into power saving mode (no view at all), and meanwhile the PC boots up, runs for about 10 seconds, and then the internal speaker recites a beep code (once only). I’ve recorded it, so it can be heard at, I can’t really describe the beep as I can’t make out if there are pauses in it or not. The PC won’t show any image on the monitor when starting up, not at any point, the monitor just goes straight to power saving mode. My motherboard is Asus A8N-SLI Deluxe, BIOS rev. 1016.

I have checked the monitor plugs, started the PC with only the power plug and monitor plug on, checked the RAM seats, checked the AGP graphics card seating, and all the other wiring, started the PC over and over again, I’ve booted it only with the essential parts plugged in… and nothing. Only once I have got the image in the monitor (When I plugged the CPU fan off and booted, and when I put it back in, it was back to no image, and this trick won’t work again, tried it), it showed the BIOS screen (Motherboard picture and BIOS version, not set-up BIOS), then it went through the normal checking the memory etc. and then got to the raid sata screen, showing some raid sata BIOS version 5.1.39 and got stuck there. I’ve got only one HD, Seagate Barracuda 160Gigs.

Hi there, Yesterday my Avast antivurus crashed, which itself was very unusual. I have run a quick check and found a few trojans, which names I have forget regrettably.I've scheduled a deep scan at the boot, reboot and left for work. Upon return I found the computer with a black screen, impossible to restart.At the boot one can only hear cpu and chassis fan tests, then a double beep and then nothing. No post screen nor splash screens. Can't enter BIOS settings.The monitor is OK. I've reset the CMOS and battery, to no avail. One  by one I have removed all peripherals trying to boot at each step, but the outcome was consistently null.Dealing with such symptoms I would normally assume the motherboard is good to go to the bin, but the specific circumstances -  trojans and all this stuff - make me think twice. Could some trojan or other malware put me in such a mess? If so, what to do next?

Answer:M58p at start-up double beep, no post screen, no splash

Trojans shouldn't affect booting. I hear two beeps out of an M58 and I immediately reset the memory. M58s are sensitive to the memory sticks being jossled out of position. Completely remove your memory and re-seat the sticks in the same slots. Did that do the trick??

My friend has spilled some tea on her laptop, after letting it dry at first it worked but now on start up it just beeps: 3 long, 2 short, 3 long and 2 short.

I can't find the beep codes documented anywhere, but if anyone can tell me what that code is I can at least decide whether it's worth trying to salvage it or clean up the mainboard with isopropyl alcohol!

I've tested the memory on another laptop and it's fine but I can't really test the CPU or anything else.

Thanks in advance

Answer:Satellite C650D-10K Does not start, what does this beep code mean?


The beep code appears mostly if the POST cannot be passed correctly.
If problem is detected before the BIOS initialize the video card and the code cannot be displayed on the screen the BIOS will play several beeps.

Every BIOS supports own beep codes meanings.
For example the Toshiba BIOS beep code is not the same like a Phoenix BIOS beep code.

As far as I know the Satellite C650 supports an Phoenix BIOS.
But the BIOS is modified by notebook manufacturer therefore it could be possible that the beep code are different.
However, you could try to search in the internet for a code description.
I found this site:

But generally such malfunction cannot be solved easily.
I would recommend contacting a technician with a huge notebook experience to scan the hardware for possible fault.

Hello people. I've very recently come across a big problem. When cold starting up my HP Media Center m7000 computer I hear 2 short and a long beep. However I can start the machine apparently using a trick which is to turn it on and keep holding the button until it turns off again and then quickly turning on once more. This seems to work after a few trials and today it worked after i opened the box and touched the wires connecting the power button to the motherboard. I've tested the graphic card and it is ok. Could this be a virus? I've changed nothing in my computer, in fact it's untouched for it's lifetime. Another interesting factor: When the computer has been running for a while, there is no problem at all, it will start, restart and cold-start. The next day the problem repeats itself. This isn't supposed to happen to HP computers Any clues? Thank you very much!!!!!!

Hi all

Just picked up a Satellite Pro 6100 with a few problems.

It will turn on, the HDD light shows and I can hear drive activity. However, the screen remains blank and a single beep can be heard after about 20secs. The blank screen I understand, it is probably the power board issue that plagues the SP6xxx series. However, the single beep I don't understand.

I know 2 beeps or 3 beeps is memory incompatibility but does anyone know what the single beep denotes ?


Answer:Satellite Pro 6100 - Single beep code on start

Hi buddy,

To be honest it?s not easy to say what is causing the problem because it could be everything and Satellite Pro 6100 is pretty old notebook.

Have you installed two RAM modules? If yes remove one module. Try always one module only at the same time and test it in RAM slot A and B. Maybe one module is defective or one slot.

If not it seems to be a problem with mainboard or CPU itself. If you can exchange these things, try it yourself because a repair would be too expensive for this oldie I think.
Second hand spare parts you can get on eBay? It?s worth a try! ;)

The XPS 630i motherboard failed (the Ethernet port and both PCI Express slots were not functioning).

It just needed the waterblock and cooling system installed, which is just recently completed.
When attempting to start the computer, it plays a continuous beep for 25 seconds, pauses for 10 seconds, beeps again for 5 seconds, pauses again for 10 seconds, beeps again for 5 seconds, then stops.
There's no video display.

I have a 5year old satellite 3000-514 notebook and now it starts only when it wants.
Most of the time, the screen stays black and the notebook emits four sounds, four beeps.
I can try and try again nothing happens, until it starts????

It is very annoying, does anybody have experienced that same pb ?
Does anyone know how to solve that problem ?

thanks for your help


Answer:Satellite 3000-514 often doesn't start - beep code appears

It sounds like the notebook cannot pass the POST (power on self test) successfully. The notebook beeps because there is a hardware error and some device did not pass the test.
You can try disconnecting all external devices and then try to start the notebook.
But I don?t see many chances that this will help to solve the problem?

Mostly in such cases the external help is needed. The technician with much more experience as a common user like me and you should check the notebook. I hope there is no motherboard malfunction because this could be a little bit expensive :(

I recently noticed that the system was trying to do 7 updates every day at closedown, and found that update was giving a return code of 800736b3.

I have run SURT several times, and it doesn't seem to give any results (or should I be looking somewhere else?).

I ran sfc /scannow and extracted the results and they are in sfcdetails.txt (attached). SFC said there were some files it couldn't fix, even though sfcdetails.txt says it has fixed all of them. is much too big to upload using the paperclip - is there another way?

I tried restoring to an earlier restore point, and unfortunately all the attempted updates have flushed my list of restore points - and the oldest few all give me a return code of x00000022.

when i switch on my main line that connect to my computer, my cpu automatically starts, cpu fan also works, cd drive also work perfectly but there's no display in monitor. monitor works perfectly when connected to another cpu

Answer:computer start but no beep no monitor display

I suspect the display-adapter (also called a graphics card) has failed inside the computer that the monitor does not work on. In which case, you need to replace it with a new one.If the existing (failed) graphics adapter is integrated "on-board", you need to disable it in the BIOS Setup before fitting a new one into a spare PCI or AGP slot (whichever type of slot is available).The reason for disabling the integrated graphics adapter is because it cannot be physically removed. Disabling it is necessary to prevent the system from detecting it in future.

So i've had no problem with my computer until random BDODS Freezes, screen glitches and last but not least Windows not booting. So i decided after a couple days to take out my Video card (Nvidia) and clean it and all of that and as i was taking it out it got jammed but eventually i got it out by just pulling it out hard (Sounds bad but i couldn't push it back because it was like jammed) Anyways i examined it and nothing appeared damaged but as i was doing it my motherboard appeared to be flexing anyways so i cleaned it put it back in and booted it up and next thing i know a huge never ending beep and an LED was red anyways the led turned off and the beeping kept going on for another 1 minute so i just pulled the plug and called it quitsys and could see if one of you guys could help, i'm sure i put the card in the right because i out it in the same exact way.

Answer:Long LOUD never ending beep on start up, no display, help?

Well, you have either broke the GPU or the motherboard with the rough handling. You do know there is a release latch on all video cards? I think the long tone is saying "I don't have a video card installed".
Just touching delicate parts especially the gold connector pins, can also cause damage and not be visible.

With my components (see below), the motherboard does not post and instead gets stuck on error code 9.0. Everything else: drives etc power up fine. I have tried an out-of-case setup to no avail and have switched almost all components with others. I still get the error code 9.0 on my led display. There is no output to the monitor whatsoever. Here are the components I used during my simple boot procedure:

PSU: Thermaltake TR2-470W (and tried with Winpower ATX-450)
RAM: Corsair XMS2 DDR2-800 (PC2-6400) CAS 4 1gb stick (out of a possible 4x1gb sticks available) (and tried with ADATA 2gb DDR2-667 stick)

CPU: Intel Core 2 Duo E6600 with stock intel fan (tried with Q6600 also)

Thanks for your time and help! I have tried clearing CMOS countless times, holding out the insert key when booting, pressing delete after powering on.) Additional info: there is a loud siren sound (up-down-up-down) that comes from a speaker that I attached to the motherboard's header.

Occasionally though, it will do a BEEP BEEP BEEP PAUSE BEEP BEEP BEEP PAUSE (repeats).
This happens on boot and sometimes when I am using it. Sometimes it turns off suddenly when I am shifting the computer around. It's extremely loud.

What is causing this? The sound seems to be coming from around the area the Memory banks are under the laptop, but nothing seems to suggest that anything is wrong.

Press and hold down the power button for 15 seconds.
Then connect back all the peripherals and check if the beep pattern repeats and reply us with the beep count.

When I power on my Inspiron N 5010 laptop, it gives beep sound and display is blank. It gives 8 beeps continuously and then after a pause again repeat the same. How the problem can be recovered. Before this problem system shows an error msg on screen and does not start normally ( starts in safe mode) for some days and one day it starts normally and after that screen goes blank. I m attaching pic of error msg.

Answer:Laptop is giving beep sound and not starting

Eight beeps means the system isn't detecting the display panel.
First thing:
Power on, and hold the D key through powerup, which will trip an LCD test.  You should see alternating solid color screens.  If you don't, replace the display panel.
If you do, next thing is to disassemble the system and carefully check both ends and the conductors of the cable that connects the mainboard to the back of the display panel.  Be sure all the pins are in good shape and that there are no breaks in the wiring harness.  If you see any evidence of pinching or bent pins, replace the wiring harness.
Finally, if the above produces no effect, it's the mainboard that's bad.  Whether you want to spend a couple of hundred dollars to replace the board on a system this old is open to question;  you are likely better off replacing the system rather than repairing a system this old.

CPU fan spins, RAM LED on motherboard comes on, CD drive lights flashes, hard disk light on front of case comes on. But no display and no POST beep.1. Replaced the graphics card with one from a working PC, same result, no dispaly, no POST beep. Put graphics card back and other PC still works.2. Replaced the PSU with one from an identical working PC, same result, no display, no POST beep. Put PSU back and other PC still works.3. Checked the with another untested monitor, same result.4. Ran test on original monitor result 'test good' signal rec'd.5. Decided that something on the motherboard or CPU had gone awol so this evening replaced both with brand new items.6. Put PC back together with the known working PSU (just in case the original had been the initial problem) from the other PC, and guess what, no display, no POST beep.With no POST beep and no dispaly I don't know where to go next.Anyone any ideas?

Answer:No POST beep

Try stripping it down to a skeleton system out of the case (on the bench) with just motherboard, CPU, heatsink, fan, one RAM module, graphics card, hard drive and PSU. See if you can get a display, Ollyolly.

Question: No Post Beep

No Post, No Beep. Bad MoBo?

after reading many threads about this subject i feel i should describe the problem i'm having, to know what my course of action should be.

i don't know for sure what was the cause of the malfunction but it started as system lock-ups and now the computer won't even power up. it seemed like video-card problems at first, because everything would freeze when i tryed to watch movies, and video problems could be noticed. yesterday after trying to deal with this video problem in lots of ways, i tryed to turn the computer on and nothing happened, no beeps and no post. when i push the power button the cpu fan and the psu fan rotate for half a second and then stop. i have to cut the power to the psu and reconnect it in order to try again. sometimes the power does go through but still no beep or post.

i tryed removing the cmos battery (all the removing done with power off in case you were wondering) and replacing it later, changing the jumpers to reset the bios (after doing those things i started getting more power ons than before), taking all out except what is absolutelly necessary, leaving only the cpu. tryed adding the ram, then tryed adding the video card... nothing works. i wonder if the video-card is needed for the POST BEEP to be heard. anyway, the main reason why i'm posting this is because i wanted to find out what is the defective piece here, as i suspect the mobo, the PSU, video-card or CPU (or RAM?).

Hello! Welcome to TechSpot!

A shot in the dark---it might be the MoBo.

My T61 will not post or beep.  Please help. I recently update T61 - 7659-12U with Middleton BIOS and T8300 CPU.  I also cleaned fan during the process.  Everything worked well for a few days but died completely without any warning. Turning power on without battery. the battery light will turn on momentarily and the AC power green light remains on.  No other signs of life (no other lights, no fan, no beeps, no disk movement).  I have tried pressing power button 10x and removing CMOS batter tricks. What do the experts recommend? As a last resort If I have to replace the motherboard, what should I look for? Thanks in advance.

Answer:T61 will not post or beep

If you remove the ram it should beep when you power on, if not, then it's most likely a bad system board.  Did you have any problems before you did the updates/repairs?

Question: No Post beep

  Well I reinstalled Win XP and it froze on installing your network. After fifteen minutes I did a hard boot. No post beep and the monitor states Monitor G, Check your signal cable or cpu. I switched the following to parts that I know work, all new, (video card, and mother board). Checked the monitor on another system. It is fine. Still the same thing. The system will turn on and I hear it counting, the hard drives are working and the CPU fan is working.  But, still no post beep and the monitor says the same thing. Now we are down to either the RAM or CPU and maybe power supply?  Or maybe a short in the case. Anyone have any ideas? This is baffeling. As I said, I hear it counting and hard drives spin and the CPU fan spins. But, it turns on just that to turn it off, you have to unplug it. CPU maybe or case or other ideas?Thanks,Don

Question: NO POST BEEP

Hello.I have been reading with interest some of the causes of a PC to fail to boot into windows, when the usual single POST BEEP is missing.I have this problem, but what i cannot understand is why switching off the PC by holding in the silver button for a few seconds, then switching off the rocker switch on the back of the PC, leaving for a few seconds, and switching back on cures the problem every time - i.e the computer then boots into windows succesfully.I am not sure whether to just keep performing this action or to look at the cause( maybe a memory problem ). As yet i have not run a memory test programme.My PC is a Microland Tech CB150 - Running Windows XPMany ThanksPaul

Hey guys, good forum you have here, i'm learning a lot.

Normally i can fix a broken pc but this one im puzzled with.

I have a Pentium 3, slot 1 Xblade computer with an Intel M/B which will not display a bios screen or beep. Sorry I can't give more detail, the pc is not mine.

I've rejigged the memory, took out all pci cards, tried another agp card, tried another monitor, removed all IDE's, tried another PSU, renewed the cmos, and then the final step was I replaced the whole motherboard using paper washers just in case it was shorting.

Still the same result, as soon as I plug in the PC, it starts on its own accord and alls I get is the red HD activity light on permanent. All the fans and PSU spin as normal, just no Display whatsoever.

The only thing I can think of is dead processor (rare) or faulty case.

Any ideas or suggestions please?

Question: One Beep on POST

My Dell Dimension 4100 emits a single beep during the POST on every boot-up. Dell Tech support site says it's a memory refresh failure, and to re-seat the memory modules. I've done this, as well as test each of the two modules separately, and have also inserted a third memory module. In all cases I still get the single beep on boot-up. (The PC hangs up regularly, doesn't always shut down properly, and sometimes hangs on startup.)

What else could be the cause of the beep, and how to fix it?

i've assembled a pc which will not start. it came as a case/mobo/cpu/fan/memory fully assembled. i've added a hdd and 2 optical drives and a floppy drive. when i power up the fan spins and the power light is on and the hdd light flashes. on the screen the memory count is shown and the drives are detected. there is no post beep and when i press del to enter setup nothing happens. it is a good keyboard. i have tried clearing cmos by resetting the clear cmos jumper and tried swapping memory sticks with known good memory to no avail i just cannot get into cmos or any further than the screen which shows that the drives have been detected. can anyone help, please.

Answer:help! no post beep

No post beep!case speaker connected?However if it gets to POST screen where drives are detected then motherboard cpu psu memory are ok.Next it should access operating system from either CD floppy or HDD, depending on how set up in BIOS.There will be an message to tell you which keys to press to enter "setup" something like del esc F10 etc.If your HDD is from an old system has it got an op system installed?If so then the drivers for the old boards will conflict with the new.Either:no op system then boot from CD or floppy and install windowsold op system boot from CD or floppy and format drive and install new op system.

I understand that this means there is a system board error.  I have a very good reason to believe that the BIOS had an issue (when I checked it before this happened, it had 75 boot options listed and said the volitale memory was almost full). Question: can I somehow force the BIOS to reset itself?  Is there a pin short I can use for this? Of course I am 2 weeks out of warranty :/  I assume if I sent it in they would just charge for a boarsd swap... likely $500-$600 dollars. Thanks for any help!

Answer:X230 1 beep, 3 beep, 3 beep, 1 beep, no screen: can I reset the BIOS?

1-3-3-1 means no memory. If you have 2 DIMMs, try with just one, then just the other. When you try with just one DIMM, it needs to go into slot-0. When you have the machine sitting lid-down and the battery compartment away from you, slot-0 is the one on the right.

This issue started on Tuesday and the first time it occured a BSOD appeared upon login, and unfortunately I wasn't able to take the error in enough time before the memory dump. Any thoughts on this issue would be greatly appreciated. Thank you,

Answer:T61 Beep Codes at POST

1 long, 2 short is an error with the video adapter.  This isn't specific to IBM systems either, that code is the same for pretty much every BIOS out there. If you let the memory dump finish you can probably still find it on the system and analize it now.  If your settings are for a full dump it can be found in %WINDIR%\Memory.dmp and a partial dump would be found in %WINDIR%\Minidump\%DATE%.dmp.

How it happened: Computer's been fine for months - pulled out video card - dusted off all fans - put it back in - no POST beep.

What I've tried:
Reattaching the video card several times and cleaned for dust on and around socket/card. Reseating RAM and booting with each chip.
Cleared CMOS (I think, ~30 seconds on CLR RTC (should it be a full minute?))
Making sure that all cables are properly connected (they should be as I didn't detach any internal ones initially)

I posted this elsewhere and have since discovered that place was inappropriate; sorry.

Fixing an old machine, p3 phoenix bois, and it boots with a single beep, and seems fine until it initialises the keyboard. What transpires i can only describe as an angry successive beeping that develops into a seemingly continuous beep. The background is bizare, at least as far as i understand it, a client brought in 2 machines, the first had swolen caps on the board, which we replaced, and ran successfully for some time. However, the keyboard began to stutter with beeps after post and after re aligning the pins also worked fine. Subsequently, the client brought the first back, the keyboard had begun beeping again, only with more intensity and irregularity, simmilar to a stuck key but more erratic. I sent the client away with a new keyboard and success. However, the client returned again, reporting that the beeps had begun again 4 or 5 days later. Again I replaced the keyboard with, and no beeps. Subsequently the client brought in a second machine reporting that the first had persisted with its beeping issue, and that he had chosen to use another machine at his disposal. As it turns out the second computer had the same issue, solved at least initially with the replacement of the keyboard. The problem still persists however, and seems to have gradually worsend over time. In both cases the same original keyboard may have been used by the client, in the case of the first machine the keyboa... Read more

Answer:Continuous Beep After Post

You sure this client isn't messing with you and has somehow caused this? Are there any *.bat files or something similar that have some code in them to cause this? I guess last but not least, is this an error code that the bios is throwing you due to heat problems or something of the sort.

Just seems a little suspicious.

Hi there I'm new here and would like some advice. I've just purchased a bare boned R40 with no ram, hdd or cards. It was advertised as "posts to BIOS" but I've not been able to get it working. I've added correct memory using both slots, one stick tried on each side, with battery and without, power x 10 plus 30 etc etc. All I get is usual LED lights, fan spin then just power and battery light. When you power off you do get a tiny click but no life in the screen. Any suggestions how to test and see if the system board is fried? Jaba x

Answer:R40 No splash, beep or post.

First, I am making an assumption that the board came with a CPU. The reason I am asking is that R40 came with both Pentium 4 and Pentium M CPUs. The CPU must match the board. The most basic test is to pull all the RAM and try to start. You should get a beep pattern 1-3-3-1.

Let me start off here... XP Pro, 2.8G, 1Gig RAM, 5 year old E-machine which mother board I've replaced since then.

Two days ago my computer wasn't working and gave me a Unmountable STOP Error blue screen. So I fixed that by repairing my Master boot record, but after that I had my computer up and running. So I took this time to defrag my computer, so I left to work while it was defraging when I came back I turned on the monitor to see if it was done(which it should have been by that time several hours later) and found my computer off altogether. So I started checking a few things and when I turned on my computer my monitor would not get a signal and it would give me three POST beeps about 3 seconds long each, but the CPU Fan would come on and my hard drives sounded like they were working and the PSU fan would come on. So I figured it was my CPU that over heated or shorted out, I had in the past never had luck with my mother board. Then I went and got another CPU and replaced it in my computer re hooked everything back up and turned it on it sounded like it was working but again I got one POST beep and then my computer will turn off. And again the monitor would not get a signal for the 5 seconds total its on, after thinking about it I'm thinking that it might be a PSU issue but I will have to wait till I get another one to test it out.

If any one has any suggestions about my perdiciment I would love to hear it, and I'm sorry if I wasn't clea... Read more

Hi again,

Fixed the old problem of the computer rebooting.. I just gave up and awaited a new CPU through the post.

Fitted the new CPU, now when I boot it up I'm not getting any POST beeps or display through monitor.

I've read topics around tinternet and everybody says it's mobo or CPU.

The mobo is less than a month old, and the CPU came two days ago.. I'm pretty confident that it is neither of them (if it turns out to be.. I won't be surprised though)

I've ran a basic boot with only mobo, CPU and HDD's attached.. same problem

Checked the pins on the processor and in the CPU slot, all seem pretty good. All wires that are supposed to be connected are connected so can't see a problem there.

I also disassembled and rebuilt the PC while it was completely unplugged on the floor, so don't think I shorted anything...

Please somebody help

Intel Core 2 Quad 2.5 Ghz
Corsair Vengeance 8Gb DDR3 RAM (2x4Gb)
Asus DDR3 Mobo

Answer:New problem - Not getting a POST beep

I've also tried refitting the old CPU which I know worked and still not getting a POST beep at all

I've got a friends old p4 here to work on.. but it needs a little more expertiese than I can donate.

With everyting in the computer.. It won't post.. The hard drive light flashes, but the monitor never cuts on. It's not giving error beeps either. When it starts, it just sits there. First thoughts were the video card.. then ram.. I've swapped vid cards.. I've taken both sticks of ram out and tried them individually. With the ram out.. it actually gives an error beep. (3 long beeps to be specific) Thats the only way I can get the bios to give a sign that it's trying. It doesn't beep with the vid card out. (possibly because it does have onboard.. even if it's disabled..) I tried the onboard video.. still nothing.

Any other ideas short of starting over with a new motherboard and processor? My friend is a bit strapped for cash so I'm already trying to save him some money. $200 isn't part of the fix atm.


Answer:Won't post but will beep if ram is removed

The RAM could be preventing the system from booting tho It should beep if it's bad.

So the PC doens't beep when the ram in but beeps with the ram out? Everything else in the system for it to beep just ram missing?
