No Boot/ POST beep code 1 long:2 short

Question: No Boot/ POST beep code 1 long:2 short

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.

Hi,  I recently updated my BIOS to the latest version using the System Update tool from Lenovo. For a while everything seemed to be working alright, as the BIOS was dowloaded and the computer rebooted. After rebooting the first time i was presented with the BIOS utility, and noticed that the update was progressing.  After 20 or so seconds the computer rebooted again. This is where my problems began. The computer immediately started beeping this short-short-short-long melody from the speakers. I thought this was normal, so I left the computer on for quite a while.  However, the beeping never stopped. Now the beeping resumed the instant i plug the power back in. I have yet been able to actually getting any sort of information on-screen telling me what's wrong.  I've tried following the "Recovering from a POST/BIOS update failure" on page 267 of the Hardware Maintenance Manual, but no luck with that so far. No matter where I place the jumper, the beeping code is the same short-short-short-long melody (yeah, it sounds like a disney tune or something). Any bright ideas? The machine type is a M92p 2992-B3G I'd hate to have to send it in for repairs, and Lenovo's Norwegian support line doesn't open until Monday, and there seems to be no way to call their 800-number in the states from here  Oh, and would this be covered by my warranty if repairs / motherboard replacement is the only way out? UPDATE #1: I found...

I've got problematic Dell Inspiron 1564. Suspected bad video.
When turned on, screen is blank and beep codes are "long-short-short-pause-short-short".
I can't find info about this beep code. I've found that long-short-short is bad video but what about next two short beeps?
Hard drive activity looks normal after that and I guess system works fine except graphics.External video output doesn't work.

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!!!!!!

Answer:Lenovo H330 Beep Code: 1 long 3 short and blank screen

Welcome to the Lenovo Community !
I haven't come across any documentation for your model that will explain that beep code.  A 3 beep code is related to memory.  Just to be safe you might want to try reseating the memory modules to insure they are making good contact. Just remove the memory module and then re-insert.  Page #36 of your model's Hardware Maintenance Manual will explain how to remove the memory modules for your reference.  The link below is for your model's Hardware Maintenance Manual. When working inside your system please follow all precautions and recommendations that are noted in the manual.
If the problem continues, I would suggest testing the memory with the free MemTest program I have linked below...

My screen went dead & the bios fault alrm went off. Two short beeps then one long beep. Looked it up and it says video fault. Took out my graphix card & cleaned fans etc, but still get alarm noise. If I change my graphix card will this solve this fault? or is there some sort of video circuitry on the Motherboard that could have a fault. Don't want to spend money on a new card if the board is at fault - will just get a new system in that case.

Hey, I have a problem with my won't boot up; as soon as I try, I get 1 long beep, followed by 2 shorter beeps. There is no display on my monitor either.

I'm really stuck at to what to do...I've done the usual taking out battery, booting without power supply, letting lappy heat up, removed and reinserted both RAM slots, checked the fan was working okay, tried to boot using a different monitor (acted as if PC was on standby)...all to no avail.

My laptop model is:

It's about 16 months old, so past its warranty, I read that the beep pattern was a BIOS code for Video Card failure, which I now presume is the problem, but just wanted confirmation so I don't end up wasting a bomb of money if I need to get it repaired (diagnosis usually costs at least £50 here :s)

Any help would be greatly appreciated, unfotunately I'm no pro with these things...

I just built a computer for the first time - I've had 2 different people look at it as well as hours spent on Ventrilo discussing what I may have missed.

The Computer:
Intel Mobo DP55kg
Processor Intel i7 870
no onboard graphics
ram is corsair 1600mhz 4x2gb chips #CMX8GX3M4A1600C9 ddr3

So basically when I hit the power button - all the fans etc come on but it won't show up on the monitor. One short beep happens showing it's booting then after a few seconds I get 2 long beeps, pause, 2 long beeps.

Now the information that came with the mobo says this is a graphics error - I've already replaced the graphics with a brand new one. Some other forums suggest it's a memory error - but could 4 different sticks really be bad? A friend suggested a bad batch, but before I go out and buy more stuff that I'll end up returning to the store - does anyone have any other suggestions as to what is causing this?

Things I've Tried:
Replaced Video Card
Tried different connections with video card
tried 4 different sticks of memory in all 4 different slots with different combinations.
took the entire motherboard out and made sure no posts were touching then put it all back
tried just the basics, no HD or Sata cables
reseated the processor

Hi, I have an Aspire M3420. Computer won't boot up with the Gefore 750ti in it and I receieve 1 long beep and 2 short. Motherboard is AAHD3-VC and PSU is 300 watts. Ive been searching for a while and this appears to be a problem for people even after installing a higher wattage PSU. Any suggestions?

Answer:Gefore 750ti won't boot (1 long beep, 2 short)

1.  What operating system came pre-installed on your computer?  If windows 8/8.1 came pre-installed, then you can try going in to bios settings and disabling Secure Boot. 2.  What BIOS version do you have?  Is it the latest for your computer?  If you don't know which BIOS version is for you computer, please post and someone should know. 3.  Which Nvidia 750ti do you have?  EVGA?  MSI? etc..can you give more details on the card you have?  The exact model number? Some 750ti use only power from the PCI-E x16 slot.  Some 750ti require additional power.  Not enough info to try to determine if it's a power supply issue. 4.  Did you try to reseat the card and then keep computer's power cable unplugged from the electrical outlet for 1 minute? 5.  Don't get me wrong, this is a good forum to come to, but I would definitely call the manufacturer of your card 800 number.  They might be able to tell you in 2 seconds what the problem is.  Anyway, thats what I would do.

About 8 out of 10 times that I power on my machine I get One Long Beep and Two short beeps on boot. I've looked up this error code and it seems to point to a video error. However I have tried another pci-e card (that I know works) and I still get the same thing.

I have removed all cables and cards from the machine and cleaned then reseated everything. I have tried various sticks of ram in various configurations (1 on its own, two, four, etc), I have unplugged all external devices while booting, tried the aforementioned other video card... all of this to no avail, the problem still occurs.

The only thing that seems to make any difference, is tilting my pc forwards or backwards 45 degrees or so... but even this doesn't always work, I end up resetting again and again until, eventually the PC powers up and does the single bios beep. The machine runs fine then, until I reboot or shut down and the fun starts all over again.

I have also cleared the CMOS, tried booting up with less items plugged in. The thing that baffles me is that my PC ran perfectly well for almost two years, and then without a crash or anything this has started to occur. The system is plugged into Belkin surge protector and the leds on this tell me that there has been no surge on the power socket.

Answer:One Long Beep and Two short beeps on boot... no video display

PSU or the actual slot/motherboard may be the culprits. Easiest to try a different PSU first and if that still causes the errors, you may end up having to get a new mobo. I have also heard sometimes that bad memory can cause video problems.

So that in case your laptop fails while you are overseas, you will still be covered for repair as part of the regular warranty services. (Also, the international warranty follows the model number of your machine, and it is set so you can't upgrade to get more coverage).Depot warranty versus Onsite Warranty is the one thing that you should contemplate when you are selecting warranty.Depot means that you have to send the laptop back to a repair shop (or depot) to get it fixed.

Answer:CPU fan is working for few seconds and stoped then a long beep and 2 short beep

Hello, Your reported T61 bios beep codes would indicate you have one of the following failures: System boardLCD assemblyDIMMThe DIMMS would be my first choice to test so, if you have more than one DIMM installed, try  try removing one of them and try to boot, if OK, you have removed the bad RAM; however, if the results are the same, remove the other DIMM and install the one you removed previously. If you can boot OK now, you have isolated the bad RAM. Now, if you can't boot with either stick, then, I guess the RAM is not the problem (unless you have two bad sticks and I doubt that). See the  Memory Removal and Installation Guide for more information. Good luck!

Answer:Compaq bios freeze short beep long beep

Is the beep pattern just one short one long? Check your manual for the POST beep codes to determine what it is telling you. All POST beep codes are different so there's no way to tell unless we know exact model of your PC. The manual usually has the beep code in it, though.

Hi there, I have a Thinkpad R61 with an nvidia nv140m graphics chip. It is roughly three years old and out of warranty. My computer suddenly stopped working (put it to sleep one night, and it never awoke). When I turn it on, I hear a fan start up, lights turn on but the display remains blank, and I hear three beeps: one long, two short. Looking online, I have found that this can refer to the system board, the lcd assembly, and the ram. I have tried reseating the ram but it does not make a difference. I tried booting with one or the other dimm in place, and feel that this rules out any RAM failure. I saw a thread on this forum referring to the T61p which had a similar beep-code, and different nvidia chip (G86) that was affected by the same nvidia manufacturing defect as mine (G84 family). In contrast to the seemingly large number of posts on the T series forum of users reporting this problem, I have seen only one other post in the R series forum with a similar issue. Is there any point in calling lenovo about this problem? Even for the T61p with a documented problem and possible replacement, users have reported having to call 3 or 4 times to get a sympathetic representative to even listen to them once they find out it is out of warranty. Anyone have any suggestions??? Thanks in advance! Eva

Answer:R61 won't boot or POST, blank display, 3 beeps (1 long, 2 short)

There is no free repair for the R61, so there is no point calling them up inquiring about that. The free repair is only applied to the T61 and T61p.Your options right now are:1) fix the laptop out of warranty, which will cost around 700 USD equivalent.2) sell the laptop for parts and as it is.3) get the post warranty warranty (thinkplus) and fix it under warranty (the basic one year back to depot should cost around 150 to 200 USD).

Yesterday I attempted to boot my computer, but I only hear the BIOS beep code 1 long 2 short and nothing on the monitor, which is powered on. From my research, I've learned that this indicates a video error has occurred and that BIOS can't initialize the video screen to display any additional information. After following several guides, I have removed and reinstalled all of the hardware components (other than the motherboard, CPU, and fans). The only component that got rid of the BIOS code when removed was when I disconnected the cord that led from the power supply to the motherboard in slot ATX12V. Obviously, the computer won't run, but the BIOS beep code goes away. I suspect either a Power, Motherboard, or CPU problem. Last summer I was having a CPU overheating problem, which went away for a while but, the temperature was starting to creep back up in December. You can read the thread here

Any advice on how to proceed? It's an older computer and I really don't want to spend a lot of money repairing it since I have two others. Specs will be listed below.

Answer:One short beep, one long beep

Is it possible you are hearing 1 long - one short?
That might indicate a BIOS CHECKSUM error, depending on the brand of BIOS.

You can try a ClearCMOS procedure (CLRTC is the same thing):
Note all your current BIOS settings
Shut down the computer > remove the power cord.
Remove the 3v motherboard battery.
Move the CLRTC jumper from pins 1-2 to 2-3.
Touch a metal part of the case and Press and Hold the reset button for approx. 30 seconds to discharge all power from the board.
Put the CLRTC jumper back on pins 1-2.
Replace the 3v battery > replace the power cord > boot.
Immediately go back into BIOS and reset all your preferred settings. If the CLRTC worked you will need to reset the date and time.

Hi, Today I replaced my old graphics card with a new GeForce 9500GT and also added a new Kingston 2GB Ram Card. I installed both of them then restarted the computer, since then it has only powered on and playing 1 short beep then 1 long beep. I've tryed everything I can think of ranging from taking out everything new and putting it back to before I added the new items to completely taking out all 3 RAM sticks and reseating them. I'm not sure how a brand new unopened 2GB ram stick that fit perfectly and a brand new right out of the box graphics card can cause a problem like this. I've been through the ins and outs of the internet trying to find a solution but nothing has worked. Hoping someone can think of a unique way to fix this or how it could have possibly happened in the first place. I dont buy anything used everything placed inside my computer was/is brand new when it was purchased. Any help/comments on solutions would be greatly appreciated thanks.

Hey guys, this is what has basically happened:

Last night, I was on my PC when a powercut happened. All power gone for about 1/2 hour, no big deal...I thought. When the power came back, I was able to log onto my PC however there was no internet, and this was apparant on all other computers in my house and the router also indicated this.

I then logged on this morning, with no internet still however there was internet in the rest of the house. I thought to restart the router and also my PC, however, when I tried to turn my PC back on, all i got was 1 long beep then 2 short beeps. I did some research and found out that this was a visual problem..something to do with my video card.

Is there anything immediate I can do right now to verify this, or do something..whatever..

Thanks for your time, any help is appreciated.

Answer:long beep, short deadline :-(

Hello and welcome to Techspot.

Can you describe the 1 long beep a little more?

Does it do this then nothing?

Does it do this then repeat?

If it gives one long beep and then nothing, then it probably means you have a faulty cpu.

See Below.

Basic Beep Codes for ABIT AWARD BIOS Motherboards

No beep at all - this means your motherboard is dead, either due to a defective or underpowered power supply, poorly seated CPU or RAM, or a dead-on-arrival board

One beep - board is working fine

One long beep then machine shuts down - faulty, improperly installed or missing CPU

1 short(Beep) System booting is normally

2 short(Beep) CMOS setting error

1 long - 1 short(Beep) DRAM ERROR

1 long - 2 short(Beep) Display card or monitor connected error

1 long - 3 short(Beep) Keyboard Error

1 long - 9 short(Beep) ROM Error

Long(Beep) continuous DRAM isn't inserted correctly

Short(Beep) continuous POWER supply has a problem

A two-tone siren, generally caused by overheating or out of specification voltages

Four beeps then machine shuts down. This is because this version of the BIOS will shut down your machine if no fan tachometer signal is detected on the fan header. Make sure you attach a fan to the FAN1 or FAN4 header or clear CMOS to reset to default (no checking).

Thanks to Paul Howland & Overclockers for providing the information.

It will start up again and work for a while but then will do the same thing again. I have NOT installed anything new. No new hardware or no new software in the last several months.
Any HELP?!

Answer:HP a6130n one short one long beep

Hi there

According to HP's support website, one short and one long beeps signify that your computer is having problems with the installed memory modules. Your symptoms are also common of the same.

Your computer supports four, 1GB DDR2-667 (PC2-5300) RAM sticks. I suggest you replace the ones in your computer. You might only have one or two.

Replacing them is easy and can be done at home.

Here is a cheap pair (two 1gb modules):
If you have more than one RAM stick it is possible that only one of them is faulty while the other is fine. To test your RAM modules you will need to run a memory test such as memtest86+

To figure out which one it is, you can also take one out and turn your computer on with just one or the other. If you figure out which one is faulty you can leave that one out and run the computer on just the healthy one.

Hey guys, big problem this time is: computer, stopped working.

I turned it on yesterday and was greeted with a a long beep followed by two short ones. I had a look as my setup and noticed the circuit breaker light wasnt working so thought it might be the breaker was playing up - so I got a replacement.

It worked again, but today it started up but didnt load up the graphics card - I restarted and met the beeps again - it doesnt even get to anything when loading BIOS, just beeps and stays blank screen.

The last thing I changed was adding a few more case fans and its been working fine for about a week and a half. I'm currently doing a Masters in 3d Animation and Im way behind with my final project already working 24/7 so I really cant afford not to do any work.

PC Specs are:

X2 Quad Core Intel Xion 2.5Hz,8GB RAM,Nvidia Geforce 9800GX2,Tyan Tempest i5400XT MoBo,Vista x64,X2 Sata & X3 IDE Drives,7 Case Fans.

Any ideas?

Answer:1 Long Beep, 2 Short Beeps

Had a look around at beep codes. Someone said your MOBO was Phoenix, but none of their codes match yours.
All but one code I found says your code means a "video failure".
What's it showing in Device Manager (Sound, Video and Game Controllers)?
Could try reinstalling drivers.
Any chance you nudged the video card when installing fans? Check that it's seated properly. Pull it out, check for dust, etc, and re-seat.

Just happened last night, the machine went into sleep mode, wouldn't come out, I rebooted and that is the error beeps I received. It has been a great little machine till now. I am in contact with customer support/service in Taiwan, where I bought the machine, but I am wondering if anyone else had problems with this on their R61?  I know the T61 had a lot of problems, and I'm wodnering if it's related? Also, I cannot find my original receipt (company paid for the machine, I'm trying to get them to track back through their accounting receipts...)  but I know I paid for 3 years (2 additonal years warranty) but I have only one year listed online. Worst case scenario, if if thea ccounting team cannot locate the receipt, is it possible to pay for additional warranty, and then have the computer fixed. I do not work at the company any longer, though I still have my machine (nice of them) and I think it will be very expensive to fix if it is a mother board problem.

Dear community members,I hope someone can help me. During a BIOS-update of my R500 (2731-A11), it 'froze' and nothing was reacting anymore.

It stays with a blank screen and beeps (once long,twice short) I have read the hardware manual and it says I have to check RFU System Board, DIMM or LCD. Is there really not another way to do this.

PC 1 ( gforce 8800gt card and a 500 watt power supply )

The LG monitor went off and never came back on. My sister had an old vga Mitsubishi diamond plus 91. I didn't have the funds yet to buy a new one so I hooked that up and everything was fine for about a week or two. Then the monitor shuts off and goes into power saving mode. I assume power supply and it sits waiting for a new one.

PC 2 ( gforce 9800gtx card and a 700 watt power supply )

The LG monitor went off and never came back on. I take the Mitsubishi from PC 1 and a week later, the monitor shuts off and goes into power saving mode.

Yesterday I shutdown my computer and when I went to turn it back on it was not sending a signal to the monitor and the computer bios was letting out a sequence of beeps.

1 Long beep followed by two short beeps.

I consulted my Motherboard manual to find that the beeps meant the graphics card was loose/not in all the way. So I opened it up jostled the card a bit and voila the computer started up and ran without a problem for ten minutes. I restarted it to get some updates and...well same problem back to square one.

It seems as though everytime I take the GC out and put it back in the computer will work but if I don't then it won't work.

Built 2 computers before and havent had this headache.

New ASUS P9X79 pro and a x79 platform processor. I have the recommended brand, type of RAM.

Just completed everything (well much earlier today) . When I power on, it shots off very momentarily, turns back on, flashed a bunch of codes going through its routine. Then I hear one slightly longer beep, followed by 3 shorter ones, then followed after a pause, by a different sounding in tone beep, sometimes its 2 beeps.

The MB manual says for one long and 3 short indicates VGA not recognized, for 4 a hardware fault.

All the fans are spinning to include the video card. Computer stays powered on but nothing on screen. Boot device LED and VGA led is lit. I dont know if that's good or bad as the MB manual only signifies on board LEDs enhance the experience or something useless. I did find out it's bad if the memory led stays on. No memory LED or CPU led on, although they do flash when turning computer on.

Code on boaed is A2 inicating IDE detection, also its stopped at AE legacy boot event before. It runs through lots of codes very rapidly before settling on one and providing the beeps.

I've looked for shorts and made sure the memory and video card were seated properly. Even looked to see if I could tighten the H80 Corsair CPU cooler.

I did try and put in a new video card and the fan would not spin, put the old card back in and fan spins.

Answer:Not sure on POST long (i thnik, 3 short) then another long

Clarify please:

Then I hear one slightly longer beep, followed by 3 shorter ones, then followed after a pause, by a different sounding in tone beep, sometimes its 2 beeps.

I get you're hearing 1 long 3 short, but what are you saying after that?

On my motherboard the LEDs are a bad sign, I'll assume your's works the same way, but checking in the manual for sure wouldn't hurt. On mine they will blink at the press of the power button, then go dim quickly, that's normal.

Sounds like a VGA issue from what I can understand so far. The Boot Device LED could be lighting up out of necessity due to the POST not being sucessful, given the VGA I would believe gets picked first, and the HDD is what would come after.

I don't follow this:

Hello Geeks,

Oh, my computer is sad. I returned home from a weekend trip to find it still idling but with no internet connection. The cat had tread on the power strip to the modem and turned it off. No big deal, turned it back on but still had no connection to the internet. So I rebooted.

And that was the last time I ever saw my poor PC function. Now I get nothing except one long beep followed by three short beeps and spinning fans. From what I'd read that indicated either a RAM issue or a Video issue, depending on the bios. I am fairly certain I have AWARD bios, so I assumed it was the video. But since I didn't want to think my newish, expensive video card was toast, I removed, cleaned, and reseated everything first.

No dice. So I ordered up a new video card. Still no dice. Grrr. Well, now I'm plus one 500 dollar video card and minus one working computer. All the fans/internal lights were working, so I figured the power supply was still good. Does that mean the Motherboard slot is toast? Should I try a newer PSU? Replace the MOBO?

The video card is enormous and wont really fit into the secondary video slot, and I'm not sure that'd work anyway, though I tried wedging it past the other connections. Couldn't really seat it without risking breaking something else, so I didn't. Not sure how to proceed. Any advice is appreciated.

I was told that all it needed was RAM. I have a ton of Ram sticks. This computer has 3 SDRAM DIMM slots. When I push the power button I get 1 short beep and 2 long beeps.. then nothing happens, no display, not able to get into BIOS or anything. I have tried multiple monitors, I have replaced the video card, I have tried every single SDRAM DIMM stick that I have, I have reset the CMOS with the button and with the battery, I have removed and reinstalled the processor, I have unplugged and reconnected all cables.. still getting 1 beep and 2 long beeps. When I look up the beep codes it seems to be a RAM problem, but I have a hard time accepting that with all of the RAM sticks that I have tried that work in other computers. If anybody can help lead me in a different direction I would be extremely grateful!!!

Ok so ive been here several times over the past 2 or so years with this same issue, and every time I think I have it solved but to no avail. here is the issue:
my computer was working fine one night and in the morning it wouldnt start. I click the power button and everthing sounds fine until Its suppost to give a single beep, but insted it gives me 1 long and 2 short beeps. I have an Award bios, and when I went to check out what this means, it says it:
"Indicates a video error has occurred and the BIOS cannot initialize the video screen to display any additional information"

so im not sure what this means other than the video card is bad. the video card is pretty new and before I go any further i guess I should say that the last time this happend, I fixed it by resetting my cpu. and before you say it, yes I have already tried this.

Answer:1 long beep 2 short? (award bios)


Sounds like the video card bit the bullet :dead:

I've just put together the following system:

Seasonic x850
Gigabyte z87x D3H
G.Skill Ares Series 8GB (2 x 4GB) DDR3-1866
Intel Core i5-4670K 3.4GHz Quad-Core

I'm also running two 8800GTS until I'm able to upgrade them. I suspect they must be faulty as I'm unable to get any video signal from them. When using the on-board video out, I was able to boot the system and all seemed well. I shut-down, but now I am unable to any video, and have one long and three short beeps on power-up. I have tried my GPU's in either slot, have tried on-board display, have reset CMOS, have switched RAM into other slots. If no RAM is inserted, I get multiple short beeps.

I was running the two 8800GTS on a socket 775 motherboard that packed-up, and I ordered a second-hand replacement, but I sent it back as I thought it was faulty as I couldn't get any video. There's no way a faulty GPU could damage a motherboard is there? There just seems to be a pattern of me trying the GPU and then being left with no video...

Any suggestions will be most appreciated!

Answer:New Build, one long beep, three short, no video

Check the owner's manual for the board - it should list what the "beep" code means. If you do not have the manual that came with the board, you should be able to go to Gigabyte's website and look it up.

Hope this helps.

Hi all,

Just shutdown my PC and on turning it on nothing happened. Tried a few more times and now it's making a long beep followed by two short ones (though very closely spaced, hardly any gap between them), nothing on screen.

Reading around, it was suggested this might be a video card problem (due to the beep code). I've tried all of the following to no avail:

1) Removing all connected (USB etc) devices
2) Removing everything connected to the mobo (IDE cables, sound card etc)
3) Removing each of my sticks of RAM, followed by both at the same time
4) Removing my video card (no onboard one)
5) Resetting the CMOS

Even with everything I can think of disconnected other than the mobo power, it still beeps. This leads me to think it's the motherboard itself that has gone, rather than the graphics card (I'd expect a different error if I had no graphics card present?). This ties in with my computers rather odd behaviour over the past few months (e.g the odd blue screen, CD drive access on either drive causing it to hard reset after a bit, occasionally not starting until I leave it for a minute...), and I'm totally willing to replace my motherboard, but was just wandering if anyone had any other checks or suggestions to recommend before I go out and buy one?

And if anyone could recommend a good, cheap mobo (all I really need from it is SATA and support for my processor, I'm not too hardcore a user) that would be great.

Answer:1 long beep, 2 short, I think it's the mobo dead?

You MAY POSSIBLY have a problem with bad capacitors. Take the side off the machine and use a bright light to look carefully at the capacitors. The capacitors are small can type objects that should be perfectly flat on the top. If any have "bulging" tops, are leaking a brownish looking fluid, or the capacitors are leaning (not perpendicular to the motherboard) they may be bad.

Attached is a link showing what you should be looking for.

At times as capacitors start to fail boards become very erratic.

For months I have been having that problem, I turn on my PC and I hear this sound I have attached as a zip file. and the PC would not boot. then I would fiddle with the memory and video card making show they are in tight and then it would boot normal, but after some time of using the PC I would sometimes get a blue screen saying dumping and after the dump I would have to restart. or I would just get countless restart. I would have to power off the PS from the switch for a few hrs or over night and the power back on the the restarting would stop.

I also use and Antec EarthWatt 500 and I get the same problem, but a few days ago I noticed that my Antec was making a hissing sound, like it is leaking electricity, but the pc would stay on, until I start to play video games for a while or MAA on Facebook. the hissing would stop after a while but when something gets too hot, the PC would just restart, and keep restarting until I turn the power on from the back of the PS for a few hrs or over night and then it would start again.

I have a Sony VGN-FZ21E the laptop shows no display when turned on and give one long beep and then two short beeps. I've tried connecting a external display but this also shows no picture.

I've changed the RAM and the HHD but the beep still continue, with no display showing.

How do I fix this problem?

Answer:One long beep then two short, no display shown


Those beeps are your BIOS "telling" you something is wrong. In order to work out what it is trying to say, we need to know what BIOS you are running. When your PC boots, it shows a black screen with writing.....something like AWARD BIOS Ver 1.021.

Can you tell us what yours says? Once we know, we can work out what the beeps mean.

I'm bad at computers, so I'm not sure where to put this.

My laptop fell out of my backpack just about a foot above a carpeted floor. I thought it might be OK, but when I turn it on, I hear one longer beep and then two shorter ones. The screen remains black and never displays anything.

"Behind" this black screen I can hear the computer seeming to boot as normal. I hear the chimes when the desktop should come up, and pressing my keyboard volume shortcuts I hear the volume beeps, so the computer itself seems to work, but the screen displays nothing.

I've googled and searched, and it seems like it might be a "video problem" or "video card problem" and I've also seen references to computer memory and motherboards. But honestly, I don't know much about computer maintenance and repair, so I'm lost.

Please help me!

It is a Sony Vaio VGN-SZ680 laptop. I don't know a lot about computers, but I'm good at fixing things and following instructions. I have a copy of the SZ680 repair manual, and would really like to avoid the cost of getting it repaired elsewhere if possible. If anyone knows what needs replacement, etc. that would be awesome.

ok, heres my problem, at first games would crash often, then i couldnt even install games, saying a cabnit file is corrupt, or there is a problem with my networking. I took my comp into a shop, they said i needed a new operating system, so i bought windows vista premium 64bit installed it. First I installed wow which worked, then I had to download the patches, after downloading they wouldnt install, saying the download was corrupt, or there were too many errors in wow to reinstall it. I did a chkdsk in the command propmt, says theres nothing wrong with my hard drive, I have dual channel memory, so I bought 2 new sticks of 1g ram to replace them thinking that could be the problem. When i put the new ram in started the comp. it wouldnt boot, just a black screen and gave me the boot code of 1 long beep followed by 2 short over and over. I think that means a bad video card, i took it out, put it back in, same thing, so i used one from a different computer, same thing. does any one know what could be wrong with my comp? its like 3 months old.

Answer:1 long beep 2 short, comp. wont start

Not all Ram cards are compatible.

If you remove the new ram cards does it work?
Or if you just use the new Ram cards, and take out the old ones, does it work ?

I'd say, more likely Ram issue

You may also want to post all your Hardware system specs, including the new ram specs

Hello all,  i own a thinkpad t60 with ATI radeon x1300 graphics card. I read through your complete "T61p exhibiting 1 long and 2 short beep and black screen" thread and I have the same beep problem with my t60. Let me briefly explain you how the beeps occur in my system: My t60 had this problem after I initally formatted my system and this 1 long and 2 short beeps used started occuring. But the strangest fact is that after those beeps and blank screen, the power light in the indicator light group is on along with battery and ac power lights. But then when I repeatedly switched on and off the system, the sequence of beeps dont occur all the time. Then I completely switched off the system and when I booted the next times I started pressing the ESC keys after pressing the on button. Most of the times ( 8 out of 10 times), the first 4 times it produced the same beep codes but after the 5th time, the system turns on.  All those 5 times, I kept on pressing the ESC key once I powered on the system. Also, every time I'd a chance I did run the pc doctor to find any pro blem with the board or video card, but every time it turned out to be fine. So now,every time I turn my system off or use a stanby/hibernate whichever turns the screeen off, on immediate reboot it comes out blank but with the power indicator light on. Here by I also list any changes that I'd made:1. I reformatted the system and only then this started to occur.2. after reformatting lsat time... Read more

Answer:T60 exhibiting 1 long and 2 short beep and black screen

I think your best way of diagnosing this is to remove the new ram and install only one chip, if the problem persists, try the other. If the problem persists, then I'd try booting from a Linux LiveCD (any will do but I'd recommend boot with the option to not change anything on your PC. If you get this same problem when booting linux, then you know it's a hardware problem, in which case I'd remove as much hardware as possible, drives, cards, etc... if it still persists, then you most likely have a bad system board. In this unfortunate event your best option would be a used one. A new one would cost more then the laptop is worth, but used T60 boards are pretty reasonable, I just found one for another member and could probably help you find one to if necessary, but lets hope it's just a ram chip. And by the way, your system is limited to 3GB, but in the chipset, and in your 32bit OS they came installed with. You can install 4GB, but it won't be able to use it all.

The problem: There's no video when I turn on the machine. Everything sounds normal except that there is a long beep and two short beeps when the machine POSTs. There have been NO hardware modifications to the machine for about 8 months.

Manuals I can find online indicate that this is a video error.

What I've tried:

Removing all USB devices (all devices in fact)
Clearing the CMOS
Booting without a videocard
Booting with a brand new videocard
Testing each stick of ram individually in each individual slot

What I'm thinking:
Either the mobo or the PSU are dead. The PSU is <12 months old, and the mobo is ~6 years old, so I think it's more likely the mobo rather than the PSU. However, it's easier to pick up a spare PSU and test it, so I'll do that saturday, but in the meantime, is there anything else I should try before biting the bullet and getting a new mobo/CPU/ram? Nobody makes LGA 775 mobos anymore.

Full specsif anyone's interested:

Mobo: MSI P7N SLI Platinum (6 years old)
CPU: Intel core 2 quad q6700 (6 years old)
Video: XFX ATI Radeon HD 5770 (4 years old), also tried with a Gigabyte Geforce GTX 660 (<1 day old)
PSU: Thermaltake (Purepower?) 500W (~8 months old)
RAM: 4x 2gb sticks I picked up as a shell shocker off of newegg about. Never came with heatspreaders so no real logos/no idea on the manufacturer. (5 years old)
Peripherals: There is a DVD-Rom drive attached (>7 years old)


Answer:1 long and 2 short beeps on POST

I would start with the is a LOW END PSU with less than 70% efficiency...and your GPU requires a minimum of 450W its quite possible that you are simply not getting enough juice to the card. you DO have the 6pin PCIE connector hooked into the GPU right?? Have you checked the voltages being reported in the BIOS?? check those and report back....

POST tone sounds like 1 long then silence though possibly 2 short to follow which would suggest a graphics card problem.

Hello everyone,
I have a Pentium 3 450 mgz, Asus P2B-F motherboard, 512 RAM, 10 gig HDD, Vodoo 3 3000 AGP video card. Recently my girlfriend did the Windows update and ran update the Norton Anitvirus protection. NO other software or hardware update have been done.
She tried turning the computer on and during the POST she heard one long beep followed by 3 short beeps. I also heard the same thing. I looked up the POST codes and it means "Video graphics device not found or video card video memory bad".
I did some research on this forum and found one topic that said to try and reset the CMOS by removing the motherboard battery and jumpers. I removed the battery and hopefully I changed the right jumper. Put it all back to the original settings and still the same beep error.
I then purchased another AGP card, GeForce FX 5500 overclocked, 128 mb DDR AGP 8x/4x. Put it in the AGP slot and it still gave me the same POST beep code.
I do not know what else to do, I know the vodoo3 3000 card is older, but it gave no indications of failure. I cannot even get a boot sequence or BIOS access to check things. Any ideas??

before you are sure that the motherboard has video problems insert the video card into the computer with the case open siting on it's side and don't put a screw in. then try to start your computer. Some motherboards and cases tend to want to pull the cards out. if it doesn't work with both cards then chances are your motherboard is the problem.

Hi, While working on my laptop I got an error message regarding some memory and when I re-started the laptop there was a blank screen with one long and two short beeps. Going through various blogs/ forums and help sections on net and Lenovo website I got to know that this relates to Video board or motherboard error. I have opened my laptop and found NVIDIA graphics card mounted on motherboard which I am guessing must be causing the display error.

so far it looks like a strict hardware problem, not related to updates. however, some manufacturers try to "cheat" with bios updates - they make fan to run at higher speed lowering the mainboard temp. This does not solve the problem per se, it just makes laptop survive beyond warranty expiration date, so you, dear customer, will have to foot the bill.

Hey all,

I just recently got a large hardware upgrade (new mobo, video card, psu, RAM) and have run into problems getting things up and running. Here are my new specs.

Asus P5N-D 750i
OCX GeForce 8800GT 512MB
OCZ DDR2 PC26400 RAM (4GB package)
Corsair TX 650W Power Supply
Note: Using an Intel Pentium D 2.66 mhz processor from old system

I had a friend who is very experienced with installing computer hardware come by and over-see the installation. Everything was double checked that they were installed properly. When we powered on the system we got a long continuous post error beep coming from, i assume the motherboard. We tried disconnecting the RAM (didn't have another stick of working compatible DDR2 RAM to test with) and still got the same thing. My buddy seems to think my CPU may be the problem, as the video card was tested to work fine.

I guess i should also mention that last week i had a PSU malfunction that may have fried my old motherboard, so there is definitely a possibility that the old PSU also took the processor with it as well... Anyone have similar issues or know what a continuous loud post error beep on an Asus motherboard means? Any help would be greatly appreciated.

Answer:Long continuous post error beep!

Well it depends a bit on what BIOS you have what a continuous beep can mean but in general it means there is a memory error but can mean a system board failure or even a PSU failure.

So what BIOS do you have?

I did somehing stupid (so what else is new) and I have no intention of telling the memory manufacturer what I did.

I have a KD7 mobo (Phoenix Award Bios) and 512 PC2100 RAM. The stupid thing I did was buy a memory cooler at CompUSA on impulse. If you've never seen one it's 2 metal pieces with some kind of heatsink that fit on each side of the stick. They attach with 2 way tape and one side had an additional strip of thermal tape. Then you use 2 clips to hold the thing together and snap it in the usual memory slot.

The trouble was I couldn't get it to fit; even removed the video card for extra work room. I guess it wasn't in tightly enough, no matter how many times I tried to reseat it. Each time I got one long beep, pause, one long beep, pause, etc. and no post. Then I removed the cooler from the memory stick but the result was the same. Maybe I slightly bent it, maybe I messed it up by touching it away from the edges. I really don't know.

Is this beep code a memory error? Is there any way to deal with it short of replacing it? Any suggestions appreciated.

Answer:won't post...long beep...I think it's a memory problem

The PC can boot up to check ram, enter cmos etc, but as soon as it try to get past POST, this beep happen, leaving the screen with pure black with a blinking "_".

I was able to get the PC to boot up with a different hard drive. (replacing ONLY the hard drive)

I also took the hard drive out to run scandisk (windows), chkdsk (command prompt), seagate's seatool test (all test except advance test). No problem detected. (the PC with the problem can also identify the HD)

I plan to go out later to buy some spare DDR3 (have none currently), to test if it really is the RAM; but, it doesn't make sense that I can boot up 100% fine with this same ram with a different hard drive.

It will boot up with the normal beep like everything is ok, until booting hard drive. Also can't boot from usb storage and unable to get to the menu to choose what drive to boot.

I need some help on an issue that is driving me crazy. I have a BioStar M7NCD Ultra motherboard ( )

It was running great with 3 sticks of memory when I purchased this online. I was downloading some stuff off the net and went to bed.

I came back in the morning to a black screen but the PC seemed to be running. No key combo would bring it out of the black screen. So I hit the reset button and I was presented with a single long BIOS beep (stops then repeats) but nothing else.

I have tried the memory in other machines, I have tried the graphics card in other machines - all functioning properly.

I purchased a brand new stick of DDR333 512mb of memory and placed this in the board - same results of the long bios beep.

I have reset the CMOS jumper, I have removed and replaced the battery - same long BIOS beep.

I have tried the normal "tricks of the trade" but still cannot get anything other than the single long BIOS beep, no picture, nothing beyond this beep.

Can anyone offer some help that can get my system back up and running?

Answer:Single long BIOS beep - no post

I had this on an old pc and it turned out to be dodgy RAM, but seeing as urs works fine in another system it cant be that. Maybe the slot itself?

Have u tried changing the keyboard? a stuck one will cause a boot prob.
How is ur PSU? try swopping that if u can.

Other than that i cant help sorry

X200 worked just fine until suddenly without warning the screen froze.  On restart, one long and two short beeps in BIOS.  Removing the hard drive or moving the memory around does not change the situation. I read a long thread on the X61 that has these symptoms due to a defect in the nVidia GPU, and I am wondering if the same GPU is in this X200.Otherwise, what could the probelm be?  Thanks in advance.

First of all, that thread is about T61/p and not X61. None of the X series utilized nVidia graphics, but only Intel integrated ones.
That being said, the board could still go bad.
Try removing the DIMMs and booting with one at the time, alternating slots.
Good luck.
