Computer beep during POST

Question: Computer beep during POST

I have put together a barebones kit from Tiger but am having a problem. Upon powering up, I get a long repeating beep. Keyboard lites up when power is turned on but does not activate when computer is booted up, no video. Fans work, fan on AGP card works. CD ROM led is on. I have two SATA HDs plugged directly into the motherboard, not using IDE slots. CD ROM is plugged into the IDE1 slot.

Preferred Solution: Computer beep during POST

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: Computer beep during POST

Beep codes should be identified in the motherboard manual that came with your system. If Tiger didn't send one then check the manufacturer web site.

My Asrock K7S8X, AMD+ 2.1, 512 MB PC has always run fine, but now it starts ok although the fan seems to be racing on, then the post beep, fine, then just as the fan starts to slow and the resultant volume deceases from the aforesaid fan, a second post-style beep occurs. I have a program called MotherBoardMonitor which tells me that the minimum speed for the fan is 2500RPM, my CPU temp is (approx) 47 to 54 , Mobo temp around 31, what could the problem be, i cant find any specific info on the net after hours of looking, thanks for any help, G

Answer:startup-post beep- fan runs hard- 2nd post beep??

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

I built a gaming PC about 3 months ago, Everything ran great, until last night.Now my computer starts up but;No beep, so probably no post test?my monitor searches and then displays "check signal cable"mouse deadkeyboard wont lightWhat does work are fans, dvd drive, lights on Motherboard, lights on PS.Interesting side note is I have to push the CPU cooler fan to get it running. Once started fans stays running. So maybe the CPU heated up and died? Could the CPU be fried? Causing the no post test?Any help would be welcomeThanks

Answer:Computer powers up but no beep(no Post)

Replace that fan ASAP...Also swap in a borrowed PSU of the same or greater wattage...

Yesterday I decided to restart my computer after having it on for a week(it started to slow down noticably.) After shutting down, though, the computer now refuses to boot up. It doesn't get past POST and doesn't beep even if I take out the ram. Also, the power supply has started to make a really loud revving sound(hard to describe exactly, but thats a close description.) This persists even if the power supply is only connected to the MOBO and case fan.

Since computer is down I can't get the exact specs, but I have 2x2gb ram, 1 160gb hard drive 1 250gb harddrive, XON-450X PSU, Nvidia Geforce 8400gs GPU, CD burner, and an intel 2.4ghz quad core cpu.

Edit: I've already tried cleaning the PSU fan and clearing the CMOS. No dice.

Answer:Computer won't boot, no post beep even without RAM

Given the sound coming from the PSU, it sounds like that may be the problem. It doesn't appear to be a board or ram issue or you would expect the beeps at least.
Have you got another PSU you can try in this system as that could be the solution.

I have been using an old dell motherboard from 2004 with onboard graphics and a pentium 4 cpu as an HTPC. It worked fine for several months until the other day when the system froze playing a video. The image stayed on the screen but it was unresponsive. After a hard reset it will no longer post or beep.

The only components on the motherboard are the cpu, a single stick of ram, a case fan mounted to the cpu heatsink, and the hard drive. I tried unplugging the hard drive and all peripherals, i tried removing the ram, and i tried removing the cpu, all attempts had the same results; no post and no beep.

I read on here to replace the CMOS battery if it falls below 3v, so i tested the one it had in it and it was at 2.8v so i went down to radioshack and put a fresh one in it, it tested at around 3.3 volts or something. Still no post or beep.

I tested the system using a different power supply and it gave the same results, so im fairly sure the PSU is not the problem, but there is a very slight chance that PSU is bad, very slight.

The hard drive and fan will spin up, it acts like its going to boot and then it doesnt. I dont have another motherboard that uses the same ram or cpu socket type so i cannot test those components to see if they are working. I dont remember the kind of ram it takes but it was something fairly unpopular and not DDR, so getting more ram will probably be difficult. I have no idea what the socket type is except that it fits a pentium 4 chip and has ... Read more

Dear Friends,I got an old Dell Dimension L866R.  The BIOS seems to be Phoenix.I upgraded the CPU to 1GHz, the Memory to 512M and repalced the hard drive.  However, it always gives me a short beep after POST.  It starts normally, no problem in identifying memory and IDE drives, and the Windows XP is loaded and started with no problem.  However, I can't find a way to get rid of the beep.  I disconnected all second drives, replaced the memory, ide cable, removed all pci cards, etc.  What else could cause the beep?Thanks,Brian

Answer:computer starts well, but a short beep after POST

Is the replaced processor identified in the BIOS? Did you check the beep codes for that model on the Dell site?

My computer has went nuts on me. Never had a problem with it for 3.5 years until yesterday. This is a long story because a lot has happened so I hope you will be patient with me and read it all. lol

Out of the blue yesterday my tower made a high screech sound then froze. I restarted it, backed up all my files because i had a feeling something terrible was going to happen. Sure enough, a few hours later I got a blue screen. I tried several times to get back on and sometimes i would be able to stay on long enough to start a virus scan but most of the time, it would blue screen in the middle. I attempted to do a few system restores but they would not work. I went to bed after a few hours annoyed and exhausted.

This morning starting at 7am, decided to do a windows repair. I got halfway through it and it froze at 34 minutes remaining, rebooted and re-attempted several times but same thing kept happening. I searched google for help and found a solution, i had to go to the command prompt and delete some inf files that were causing the repair to freeze. I did that with no problem and restarted. Thats when all hell broke loose. My computer no longer would make the post beep and windows repair would just restart right after "windows is resuming your repair" or something like that, dont remember the exact words. It would restart over and over in a infinite loop. I tried to boot from cd to maybe format the computer completely but nothing, still did the same thing, also ... Read more

Answer:[SOLVED] Computer went crazy, repair keeps restarting, no post beep

Have you tried running MemTest on the RAM?

This sounds to me like either a HDD fault, or a RAM fault, some where, some files are not being read correctly, either that or the CD you are using is corrupt/scratched.

Try making another XP disk, see if that works.. also did you try just using 1 stick of RAM rather than both of them at the same time?

Try going into your BIOS and resetting everything to the defaults. IF you don't know how to do this just ask :)

Alright, I bought a bunch of new stuff for my computer(case,ram,hdd coolers,heatsink and fan.) It worked for several days until today when i went to turn it on,and it wont POST. The fans spin,and will spin forever if I let them,but it doesnt POST.

I switched out the processor to see if it was that,thank god it wasnt.

I took out all RAM to see if i could pull a beep out of the thing and,nada.

I reseated the processor several times.

The speaker is connected.

I tried several video cards both AGP and PCI in several different slots.

I unplugged everything except for RAM,Video,and Processor.

I reset the CMOS several times.

Nothing seems to work :X

What now?

Thanks much,
Tyler Bello

Answer:Computer doesnt POST,no beep codes,not processor,not video.

Does the motherboard support integrated graphics? If so, try booting without your video card (eliminating another thing).

Other than that, sounds like the motherboard is dead. Got a spare hanging around to test?

I just had the same problem with a friend's system and had to replace the motherboard.

Good Luck!

Hi, I recently built a custom computer and the minute I turn it on, it immediately has 2 short beeps, and 1 loud irritatingly long beep... At first I figured it was because there was no OS installed, however the beep still continued after I installed XP successfully. I can successfully boot up Windows, install drivers/program and there is no visible problems.One thing I did afterwards was go into the bios and loaded optimal performance defaults. Surprisingly, the loud long beep disappeared, but the 2 short beeps continued and instead of the annoying long beep that follows right after, I receive the "successful boot beep" sound that I heard a million times in my previous computers. Dunno how to describe that sound but... its the beep sound that goes off on a successful post I believe.If there is ONE symptom, I found out that in the BIOS menu the keyboard response is EXTREMELY slow. For example, if I press the down arrow key, there is a 3~4 second lag before going down the menu. What does this imply? This happens in both my USB and ps/2 keyboards.Again, no visible problems after boot up but I'm concerned about problems that may prop up later along the road. I still have time to return/replace parts so I'd like to find out exactly what the problem is. Any recommendations?BTW my motherboard is an MSI G31M3-L V2 with an AMI bios. Ram is a Corsair DDR2 PC2-6400 Twin XMS(2gbx2). Listing these because it seems if there is hardware problem, its usually these two th... Read more

I've had this computer for 2 yrs since I built it. Has a Asus M2N-SLI mobo with athlon 6400 x2. 4gigs ram, Nvidia 9800 gtx, 600W PS. Most of the time runs fine, no signs of problem. Clock's acurate no lost time. Every 2 months or so, in the morning go to boot up and no beep or post. Just runs all fans and everything but never posts.

After first time I figured out when I replaced cmos battery it works fine. But keeps happening every 2 months or so. Any ideas? Battery should last much longer than 2 months. I'm stumped on this one and even my professors at college don't know. One tech support guy said might be a grounding problem with mobo and case. But that sounds weird.

My laptop here is a Dell Inspiron 15, 3000 series. 
The laptop itself works perfectly fine, I am able to get into windows (which I installed myself, it originally came with Ubuntu). 
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.
I took a suggestion and used FN+Power to do Hardware Diagnostics which said nothing is wrong.

What else can I try?


Answer:Dell Inspiron 15 - 3000 series - Beep Beep Beep Pause Beep Beep Beep

I’d suggest that you follow the steps mentioned below and check if the beep pattern repeats.

Switch off the computer.
Disconnect the AC adapter from the system.
Remove the battery from the computer.
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.

If you still receive 3 Beeps on the system then it indicates System board failure.. You will have to replace it on the laptop.
Please let me know the findings.

Problem: Upon system startup, power comes on, but nothing else--no beep to indicated the system has entered POST. After several tries, it will finally beep and the harware will come to life.

Once working it will usually keep working as you'd normally expect as power cycle to work. It's mainly after sever hours of being off and now always, over night that the error occurs--no power to the hardware, until several tries.

I decided, due to recent bugs in my system, to reinstall windows completely by reformatting my hard drive and such. I got all this accomplished, then when windows restarted, it said I needed to restart again (something about USB 2.0), so I did. When I restarted, she went through POST and stopped with a message the said "Verifying DMI data..." and froze. I went into BIOS and verified that all IDE devices, CPU and memory were recognized by my BIOS, and they were. Still, she would not boot passed that same message. If I change my FSB setting to 100MHz (200MHz effective in the AMD world) she goes through POST and gets to the same message but an extension to it: "Verifying DMI data..................update success" then it freezes again.

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 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?).

Answer:No Post Beep

Hello! Welcome to TechSpot!

Could we get the details of these componants?
A shot in the dark---it might be the MoBo.
Yes vid card is needed, unless you have onboard vid.

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?

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?

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.

Hi, I'm new here.

My nephew asked me to look at his PC because I'm the family computer expert

But I can't fix it so my reputation is in tatters. If you can make any suggestions I'd really appreciate it.

It's a desktop PC running Vista, about four years old. When turned on there's no display and it immediately beeps. It's a long beep repeated continuously.

The motherboard is by Foxconn (N15235) and after rooting around their web site I found that this indicates a RAM error.

I replaced all the RAM cards and the cmos battery but to no avail.

Possibly the motherboard is faulty, but I can't test that.

Ideas gratefully accepted.

Answer:POST and Beep Codes

Try to only put in the minimal amount of RAM sticks required (usually two) and if you have another computer that you a verify the RAM in, all the better. If you can rule out the RAM, then it's the motherboard. The memory controllers are complex pieces of silicon and it they are the fault, you'll get the same beep error.

Hey, i got my Gigabyte EP43-DS3L motherboard today, so i put all my hardware in the motherboard, as you do. All working fine in the old motherboard apart from the CPU which was brand new.

I'm almost sure i connected everything connectly, but when i start up it just spins the fans and LED comes on, the graphics card fan is much faster and louder than previous too.
I don't get any image on my monitor and there are 4 LEDs that say Phase next to them on the motherboard

Phase 1 is green, phase 2 is green, phase 3 is orange and phase 4 is red. I'm not sure if that means anything.

Wnat could be wrong guys? Everythign appears to be plugged in and working, just the motherboard isn't startign up Cheers

I've looked at various documents, that go on about error codes, but cant find what it means. Does anyone know or can link me to a site that's inteligable? BIOS is Phonex ver 6.00pg. I similarly just put in a AGP graphics card & got the same (without doing RAM at the same time). Any advice welcome. Incidentaly it runs XP with 512mb ram in either slot, I've another 512mb to install - it wont boot with that in either slot on its own, or either combination with the existing memory.

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

I have tryed both on 3 boards (actually 6 all to geather) which I can not get to post or make any sound or send a signal to the monitor. These boards are uninstalled. I am using a power supply with Output: [email protected], [email protected], [email protected], [email protected], [email protected], [email protected] from what I have read this is more than enough. The heatsink fan comes on, starts to pol the hardware-keyboard flashes then nothing. I have tryed 1 stick of memory (Kingston DDR 2700) changed slots and with no memory still nothing, no sound. The Athlon MP gets warm as do the chipsets. For wiring I have only a speaker (tryed 3 dif) and an on/off switch. I have built many other AMD systems, however none with an Athlon MP processor. The motherboard I bought to go with the Athlon mp-1200 is a Biostar M7VIZ which states "support for Paliminos" I can not believe none of these boards will post but they do not. Any ideas?

Answer:Power, But No Beep or POST ... UGH!

The least expensive (free ) and quickest test would be to borrow a known good PSU of the same or greater wattage and swap it in there overnight to test...Also if that MBoard has onboard and there is a vid card involved remove the vid card and use the onboard to see if the card may be the culprit...Good Luck and keep us posted.

beeps. I entered the Bios to aid my diagnostics and seeing no issues I exited without
changing any settings. Computer booted normally.

2) Once Windows had booted there was another issue. booting was taking forever and I
quickly found that any processes that started would replicate itself. The programs
would continue replication till the computer's memory overflowed and crashed the

I have the following:
Athlon 2700+ XP
Biostar M7nCD Pro mainboard
512MB RAM DIMMs PC2700 (I believe) x2 (two sticks) (Kingston and Crucial)
Two WD HDDs (250GB each)
Sony DVD+/-R DL burner
WinXP Professional
450w PSU
GeForce 4400ti vid card

I usually leave my PC on for long lengths of time (2-4 weeks at a time), and last night I awoke to my PC making long beeping noises, so when I got up and checked on it it acted like it was shutdown (no lights on case, and monitor light was amber/yellow), but the beeps were still going on... so I shut down the power going to the case and went back to bed. Later today when I got home from work I flipped on my PC and before the monitor even popped on I heard the beep again.. so I waited .. another beep... and no POST... and the beeping continued... (long beep over and over)

So I yanked my master HDD (along with my burner and my video card) out of it and put it into my wife's PC (where I am now), so I could come and ask you all what you thought it was, but before running straight here I stopped by Biostar's site and various other motherboard sites to see what the beeping could mean.
I read that a series of siren-like beeps (hi/low beeps) meant there was something wrong with my heatsink/CPU, and a long beep over and over means that RAM is bad (I guess that is what I read), so here is what I did...

Answer:PC wont POST... will just sit there and beep.

to start out, its not the PSU. A dead PSU will give you nothing at all, at least in my experience.

You're correct in thinking that 5 seconds is short to clear CMOS, i usually put the jumper in clear position and remove the battery for at least 30 seconds-- but it seems you've tried that too.

Have you tried with only 1 stick of RAM (alternate, in case one is the culprit)? Can you get your hands on another stick of DDR RAM that will fit just for testing purposes?

I wouldnt imagine it was a fried CPU, though you might want to pull the heatsink off to check.

Lets keep troubleshooting so we can try to fix this, but keep in mind that Biostar has not had a great name for a number of years now, and I have heard quite a few stories of their Motherboards crappin out.

Go to Solution.

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.

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.

My other topic went unnoticed but I've managed to downsize the problem a bit in the meantime.

Issue: No POST beep thus no display on monitor

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)

Well my main computer quit today. It's an MSI K7N2 Delta 2 platinum with an EVGA GEForce 7800GS card. Athlon 3200+ XP CPU.

It won't POST. No video at all.
I keep getting a long Beep on boot up - I have removed / reseated memory sticks, reseated the graphics card, reset the CMOS (by pulling the jumper).

The manual doesn't describe the DLINK beep code of just 1 long beep. The closest it says is 1 long beep followed by short beeps. I'm not getting short beeps.

I'm getting power, but no video at all.

Basically I need to know if my video card or PSU has failed and what the DLINK error beep is. I have a generic 600W PSU and the system has run for at least 2 years straight - 24/7

I got some beeps the other day when playing a game, but the beeps went away. I have a bad feeling the video card quit on me. Any ideas? I'm thinking PSU might not be giving enough juice now that it's old.

Answer:NO POST - with DLINK beep

Hi Tedster.

Sorry to hear you`re having major problems.

I`m not sure what you mean by a DLINK beep.

My first guess would be either a bad psu/bad mobo.

Disconnect anything not required to boot your system and see what happens.

Hi everyone,I have a problem with four identical pc's approximately 2 years old at work. Pentium 4, celeron 2.2, Bio-star U8668-D motherboard with 256 mb ram. When the pc is powered on all fans come on but get no beeb from computer. I checked all the connections, disconnected cd rom, floppy, hard disc etc. to no avail. I cleared cmos using jumper and managed to get pc to start. If left for a few minutes, it is a hit and miss affair for the pc to start. I have tried to replace cmos battery CR2032 but it has not made any difference. If I try to start, I may have to make 5/6 attempts before I get the beep and post etc.Does anyone here have any suggestions.

Answer:PC does not boot - no beep, no post

I'm surprised that you have identical problems with all PC's. Sounds a bit like a power supply issue... If all your computers are acting in the same manner then is the mains electrical supply up to the job, have you added any other electrical equipment to the office electrical circuities?You could try turning off any piece of equipment that is using the mains supply and then with just one computer switched on, see if you can get this up and running if you can I would consider calling a electrician in to sort out the mains supply.I have in my time overloaded my mains electrical supply (a bungalow that was built in the early 60's so electrics wasn't up to ruining electrical goods of the 90's)turned the tumble dryer on, and blow SWEBS fuse and not my fuse box... Had to have SWEB come out and replace there fuse to get everything up and ruining again...

I went out today and came back and my PC was stuck at the "Last known good configuration screen". I tried to boot into windows using that setting and nothing happened, my PC Just restarted and the cycle began back to that screen again.

I restarted, POST gave me no errors but i was still unable to get into windows, I put my disk in and attempted to repair my installation and once again it wouldn't load, I got to loading necessary files etc (With the bar at the bottom) then the PC restart after that..

I'm thinking it could be a hard drive issue, I've got a spare old hdd i can try, but before i pull apart my PC i thought id ask here.

Answer:PC Won't boot, POST beep is OK!

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.

I recently upgraded my PC case and replaced a DVD-RW, and now on boot-up I am coming-up with a POST beep (at least I assume it is) that I can't find in the list provided by this site. Aside of the new DVD-RW, all of my hardware remains exactly the same.The beep is continuously alternating between a low and high tone, and both tones occur for the same period of time. The strange thing is that despite this beep, my PC appears to function normally and boots/lets me log into Windows XP just fine. After being on for approximately four minutes, the PC shuts itself off.I have isolated the MoBo from my hard drives and DVD drives and the issue still continues. Since it does boot normally, and seems to fail as Windows is finishing its boot process while my RAM is being sucked-up with all of the programs that initialize during start-up, could this be a RAM issue?I am using a Phoenix BIOS.Thanks for your help in advance.

Answer:POST beep I can't decipher

You probably didn't configure the Master/Slave jumper settings since you didn't mention any of that.

Recently moved, and just before I moved I'm not exactly sure what happened but the electrics (but not the lights) in the house cut out, until housemate did something at the fusebox, so either may have damaged something.

I've reseated RAM and video card, reset CMOS battery and checked cables. Fans and lights come on, if I take RAM out I hear long beeps during POST but still no boot.

Any help appreciated

Answer:no POST beep when booting

Clear the CMOS (using both methods as described below) if you have a power shutdown, that might help you get going.Turn OFF the computer and unplug the power cord.

Hit the ON button (power button) on the case to remove any residual power.

Remove the onboard motherboard battery.

Move the Jumper Cap from pins 1 & 2 (default) to pins 2 & 3. Keep the cap on pins 2 & 3 for ten seconds, then move the cap back to pins 1 & 2.

Reinstall the Battery.

Plug in the power cord and turn on the computer.

Hold down the DEL key and enter the bios setup menu to re-enter data.
Notes: Some motherboards use different key combinations to enter the bios setup menu.

There are also some motherboards that you can simply push a button to achieve the same as moving the jumper from pins 1 & 2 to pins 2 & 3 and then moving the jumper back.

In addition, there are some boards that you simply use a screwdriver to short across the two jumper pins (no jumper), but this serves the same a removing the jumper and replacing it to adjacent pins.

I Tested Video card in another PC, replaced power supply and tested SSD, Still no display. It powers up and stays running. There is no embedded speaker on the Motherboard. I guess that leaves the processor or MB?
I sent the MOBO in for repair, received it yesterday and reinstalled. I am bread-boxing and still no video.
I installed an internal speaker. No post beeps unless both sticks of RAM are out; then I get continuous short beeps. So far new power supply and MOBO. I tried posting with no peripherals. My computer starts, the PS fans run, the heat sink fan on CPU runs... Is there a way to test the CPU?
I took a stick of RAM from another PC, same results

Answer:No Post Beep, No Video

so when you have all RAM out, you get post beep but with RAM in, no beep at all?

Do you have onboard VGA connector you can try?

You sent in the mobo, but did they do anything to it at all?

If you are able, reseat the CPU. Not sure there's any other way to test it other than to swap processors or test your processor on another PC.

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.

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?

OK , no post, no beep, no boot, no clue. I have a hp dc5100 desktop pc. Intel inside 3.2Ghz , 1gig ram, all factor except some upgrade on the ram by a tech quite some time ago. I left my pc on overnight as usuall, next morning nothing on the monitor. I left it on with screensaver, not in hibernation or sleep mode. No response. so I rebooted and nothing, except the following, power light came on with fans , cd led blinks etc, but no video no post, no boot?.

I tried all the troubleshooting guidlines i know and such listed on HPs' site. Ram is good, monitor is good. with all perifials disconected. Mainboard led is on.I tried an external video card. I tried clearing the cmos. made sure connections and cables are good. cpu cooler is warm to touch. video chip warm to touch. I completley disconected all power cables, pulled cmos battery,pulled all jumpers and used the cmos reset button on the mainboard, in various sequences. restored all to original state and still... Pwer up renders no video, no post or beep sequence. P.S. when i try bootup with no ram i do get beeps for memory fault so speaker is working.

I am trying to help with a Dell Inspiron 5100.
The computer was running very slow and I've made a bit of progress resolving that. I think it needs some more RAM and I'm not sure if that could be at all related to the following.
The problem now is that after running for few hours, then shutting down, then trying to turn back on:
1. light comes on indicating computer is on
2. the computer makes 2 beeps
3. screen
4. screen
5. and so on

This does not happen everytime trying to start the computer so I'm really at a loss. I've read about overheating in this model which would seem to make sense but sometimes this will happen after the computer has been off for a day or so.

At a complete loss now.

Well anyways, I decided to break it out and get it going again. I got all my hardware, the CPU, HDD, 1GB DDR2 RAM, and a CD drive. I put everything back in properly and it does not POST beep at startup nor does the monitor get any signal. Anyone have any ideas what could be causing this problem?

Answer:No POST beep or video signal

See if there's anything in this post that helps;

Oh, and did you remember to plug in the CPU (4 pin) power connector..? That can be such a deal breaker.

Sometimes, a PSU can go bad while sitting around. I've had one myself that wouldn't restart after it was powered off. (That said, the caps were whining pretty bad while it was running).

Hey guys,

I have been reading these forums a lot without a proper account, solving various problems. However, with this problem i decided it would be better to ask for some hints towards the possible cause of this.

My system in its current configuration has been working well for over 2 years. Last night, when I shut it down something weird happened: the monitor turned off (entered idle/stand by mode) before the system actually turned off (that's the normal point when the monitor should enter stand by too).
Also, I left it around 5min but it remained in this state, not shutting down. I decided to turn it off manually, believing that it was not much of a problem.
This morning however, when I started it I got no post beep and no video signal. All the components seem to be working normally though(the green led is on, the hard drive led also flashes, cpu & psu fans are ok...). What could be the cause for this?

I tried cleaning and swapping the ram memories and it still doesn't work. If I restart after booting it, still no luck.

Any ideas?

my rough specs:

AMD Athlon 64 4000+ at 2.4 GHZ
4x512MB DDR2
Nvidia GForce 7300 GT
ASUS M2N motherboard

For the first problem I've run into the same with an MS optical type here where you would either end up removing and then reinstalling the software or check for a newer version at the company's support site. You can that type of problem with just about any type of programmable input device.

The second problem especially hearing a beep when pressing a key is typical for reaching the end of a text window and no more letters, numbers, characters can be entered or no place to put anything since no window is open. Generally that's not the board itself but a sound assigned in Windows.

Is there power to your pc and to your monitor, and they are both switched on?
Do you have power lights at both the monitor and the computer?
Have you recently moved /disturbed your computer "setup" /location?
Is it possible some cables may have come loose?
Have you tried the monitor on another (known good) computer?
Have you tried the computer with another monitor?


What were you doing the last time the computer worked properly?
Have you added any hardware or software?
If you turn on the monitor, and then turn on the computer, do you see anything on the monitor at all?
(most monitors today have a start screen made by the maker, before giving you a "signal not detected message and then going dark).

If you see a boot screen from your computer, can you get into your bios?
Can you boot to safe mode?

I've just built my second computer and I keep getting the "process failure" code when I boot. When I boot without RAM, I only get the 3 beep code. These are all new parts.

I have gone through many checklists, double checked all cords are connected, unscrewed the standoffs and pulled the MOBO out to boot. I've tried booting with nothing but the mobo plug and cpu connected, but still the same 5 beep code. I've pulled the CPU out bc I was kinda rough putting the stock cooler on, but no pins are bent or broken. The cpu fan is plugged in and working.

I'm convinced I must have been too rough with the mobo or perhaps either the mobo/CPU was dead on arrival, however unlikely that sounds. How can I diagnose this? I'd hate to have to unnecessarily buy a new part that isn't actually the problem. Any help would be appreciated.

I have an issue with the BIOS POST check that annoys me. The issue is that when I restarting my computer or turn it on sometimes during POST (when a Toshiba logo appears) there is a beep sound signal. Mainly there is no signal but sometimes there is very noise.

So, the question is: Is it a problem in the hardware or is it a problem in the BIOS (by the way, I re-flashed BIOS several times - no result).


Answer:Satellite Pro A - Beep signal during POST

Hi buddy,

That means you get only sometimes a beep code when you start the notebook or does it happen always?

Usually such beep codes mean that there is a hardware problem but I think only an authorized service provider can test this exactly.
What you can do is resetting the BIOS to default settings and if you have two RAM modules, test it with one module only.
