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.)

The computer was built from scratch, specs are as follows...

VIA mainboard
P4 1.8 Ghz
120 GB 7200rpm IBM HD
1x 512 pc2100 DDR Ram
52x Sony CD-ROM
32x10x40x Sony CD-RW
GeForce 4 MX 440 64mb
1.44" Floppy Drive

mice, keyboard, etc...

crammed into a case with a P4 power supply... i think it's 350 watts.

It was built for a friend who's going off to college in a few weeks. It worked fine, got the operating system installed (Win2k) and all the software (word processor, etc). Loaded some pictures, set the settings to the person's preference and installed all drivers for everything. Then into a box it went, ready to go.

That was 3 weeks ago.

Hooked it up to let friend know where I had put some files and how to use the burner... a quick tutorial of the new system. The thing is, it won't start.

When powering on, all the lights come on on the case, on the CD drives, and you can hear the hard drive powering on too, all fans spinning and operational. The floppy however, does not beep or light up. The annoying part is the motherboard beeps for a really long time, pauses, and repeats. The monitor never recieves a signal, so it remains in standby. I tried a different floppy and reconnected it, same thing. Long beeeeeep... no POST beep. Everything else lights up / powers up though.

It was working fine and dandy before... superly fast too. Need help! Can't seem to get it up again

Much appreciated, thanks!

I have a Compaq desktop which I have had sitting up for a while, it isn't but maybe 5 years old. I say it's been sitting up for about a year. 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).

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.

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

Hi all..

When I try to boot up my PC there is no signal to the monitor and I do not hear any POST beeps.I try to Any help please.

Answer:No post beep and no signal on monitor

Let's eliminate the obvious first:

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 got an annoying issue with my PC, my PSU died not long ago so I replaced it but that didn't solve the problem. It revealed new ones.

At first, I would only get a flicker of life from the CPU fan, so I reseated everything and removed any excess cables. With only the RAM, CPU and graphics card connected, my motherboard cycled through and beeped once. I thought all was fine, so I relocated my machine to it's usual spot and hooked it up to the monitor. Switched it back on, no cycle, no beep and no display.

I tried a second motherboard, with only one stick of RAM plugged in, the CPU and a graphics card. Still no display and no beep from POST. I have no idea what's going on, I've tried resetting the CMOS on both motherboards, three different graphics cards, having the motherboard out of the case and all the usual checks.

Quite frankly, I'm stumped. I'm thinking it might be my CPU?

For reference my hardware is -

EVGA X58 1366 socket mobo
ASUS P6TD Deluxe 1366 mobo
Intel Core i7 920 CPU
Corsair XMS ddr3 triple channel
750w Coolermaster PSU (modular)
Nvidia GTX 285 Graphics card
Nvidia Quadro 600

Answer:My PC powers up but no signal on monitor or POST beep

If your PSU died it could have taken your CPU out too. You probably don't, but if you do have another CPU try it.

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.

Question: NO signal NO Beep

ok... recently ive had problem with my processor getting too hot. my computer was still operable, but whenever i was burning cds or doing multiple tasks on the computer it would begin to make a buzzing sound and eventually just shut down. so i bought arctic silver for the processor and that helped my problem for about a month, then the buzzing and overheating came back again even worst than before. so i came to the conclusion that i just needed a brand new processor. i bought a new processor and installed it along with the new fan it came with. now when i turn the computer on, the on lights come on, the fans are working too. but usually my computer beeps when i turn it on and it doesnt beep anymore. and my monitor is saying "no signal". before i installed my new processors, i could still boot up properly and do things on the computer, but now i cant do anything. while installing my new processor, are there any mistakes that could have been made to cause all of these new problems?

Answer:NO signal NO Beep

It may be the CPU Fan. Just try plugging in the original fan and then turn it back on
If it works, change over the fan

Also confirm that your Motherboard supports that CPU by checking your Motherboard support page (some info on that h e r e)

And lastly check here: Have a read here: Tutorial: No POST (Power On Self Test)
There is also a link at the bottom of that guide for "Reseating your CPU"

Probably just the fan though

my mobo is a MSI k8n Neo4
my video card is a Nvidia 7900 GS
my power supply is an Apevia 680w Beast Power

about 3 months ago my computer started to get hard to turn on, it would do the normal beeps and stuff but then get stuck at the windows xp loading screen, and I would have to restart it like 5-7 times to get it to acually load up past that screen. after a few weeks of that it stoped giving me a beep all together. Everytime I tried to start it, it would just sit there, the fans would run, the cool cathode lighting would run, the video card ran, the HDs were spinning, the power supply lights up, but theres no beep signal and no video response.

Im pretty sure nothing is loose in my system. I unplugged everything pretty much and just had my powersupply, cpu, and mobo connected, but still no beep signal. I saw a post where someone suggested to unplug the cmos battery for 15secs, I did that but still nothing.

Answer:No beep signal, I think ive tried everything

Beeps are usually video, or memory errors on an MSI.
What do you consider "normal beeps and stuff?"But it appears you may have a hard drive problem, and possibly a cpu fan or thermal paste problem that needs exploration.
There have been a number of problems with the nVidia 7900 GS... When you have more than one problem, they are all difficult to trouble shoot.
I would go back to basics. Does your system have a floppy drive, so you can temporarily disconnect the hard drive.
Or can you use a second hard drive to do a clean install, so you can test all this equipment without the interference of Windows, infestations, and such?

I have a Nf4 Ultra Infinity mobo that I sent back to the manufacture for an rma. They sent it back to me 2 weeks later. The first time i sent it to them was because when i started the computer, the loading screen would get stuck on the Infinity logo. I took the computer to a computer store, they told me the video card AND my motherboard was broken. I went to buy a new video card and sent the mobo in.

Now Im having this problem. I cant seem to start my computer up. On the monitor, it saids "no signal". Plus there is no *beep* when i power the computer on. I upgraded from a geforce 6600 to a 7900 now. I also bought a new psu , (500w). I have a AMD 64 3000 venice cpu. WHat could be the problem.

I just bought a new Lenovo H50-50 yesterday and when I turn it on, there's no beep and my monitor stats "No Signal". The fans are on and the lights show power plus activity. (Hard disk drive indicator blinking). I've tested my monitor on my laptop that it works fine there. It's a small AOC monitor, about a year old and I haven't found that there should be any issues with compatibility there. Maybe it needs a driver, but I can't install anything if I can't see what I'm doing. I've tried restarting and pressing F1, to see if I could make a menu appear - in case it's the OS not loading properly, but my monitor remains blank. Yes - there's the CD that came with the computer, but I fail to see how I am to use it, if I can't get any signal to my monitor. Any ideas would be appreciated, but keep in mind that it's only 1 day old and I obviously don't want to void the warranty.


Go to Solution.

Answer:New H50. No beep. No signal.

Welcome to the Lenovo Community !
I am assuming that you connected the monitor to the on-board VGA connector that is on the back near the additional USB ports?  Are you sure that your model didn't also come with a graphics card that is mounted in a expansion slot on the back near the bottom of the tower?  If so, then try moving the monitor cable to the other VGA connector.
If you have just one VGA connector and it isn't working then I would recommend you contact Lenovo Support for additional assistance with your hardware problem.  Since the computer is brand new, you might consider just returning the computer to the retailer and have them exchange it for another one.

seeking help.
Have a Sony PCV-RS520, past warranty. Working properly last night, this morning, system (from the PC tower) light was on, no signal on monitor. After hard power off of the PC, I tried to restart the machine, (as many had posted before), power on, fans on, just no signal on the screen.

I tested the monitor with my laptop, it works properly. I also tested the graphic card by putting a brand new card in, same problem. I concluded that it's not the graphic card.

I also tried to re-seat the RAMs (2x256) and graphic card, nothing changed. I am not very familar with the PC, so haven't tried to reseat the hard drive, motherboard, etc. I had a bad feeling that this is going to be ugly--besides the money to spend on whatever software, I will probably lose the photos on my hard drives.

Are there any suggestions as to what's the problem? I tried to follow the earlier posting, but didn't seem to see any resolution other than getting a new motherboard or hard drive. Help!

Answer:Power on but no beep, no signal

You mention that you popped another card in to test, and still received to signal to the monitor.

Was this other card you stuck in the same as the one you took out? If for example, you stuck and ATI in when your original card was an nvidia, then you wouldn't get a signal as the drivers are different.

Maybe this is obvious, but just wanted to make sure, as if you are not aware of the above, then it is not safe to rule out that your video card is the problem.

Assuming that the above is OK, and you CAN rule out a video problem, I have another question to help with the troubleshooting.

Does it sound like your system is actually booting into windows? In other words, can you hear your hard drive going nuts as if it is loading up windows?

a few weeks ago when i went to my friends lan paty my pc looked dead when I was finished attaching things and booting it up, there was no signal from the graphics card (both my ati radeon 9550 and onboard one).

When i was booting up again i had the same problem again, but this time clearing cmos did not help me out. When booting up all fans start spinning and all drives work.

Hi im just after putting together my new pc but when i turned it on I get nothing, all fans turn on and the green LED on the motherboard is on. Although i get no beep when I get the no memory beep when all memory is removed. Also the first time i turned the pc on the monitor did recieve a signal but it was just a black screen. I then reset the bios and ever since the monitor shows "no signal"

intel e8400 cpu
4gb ddr2 corsair xms2
500gb seagate barracuda hard drive
gigabyte 1gb 4870

I have already tried the following

- Stripping it back to just stick of ram psu cpu and video card
- tryin 1 stick in each of the slots
- Resetting bios
- made sure 2 6 pin connectors were connected
- made sure 4 pin 12v was connected to motherboard
- tried video card in other pci express slot

None of these have worked the only thing i can think of now without coming to the conclusion that one of my components are dead is the the motherboard does not have the correct bios for 45nm processors.

So does anyone have any ideas on what else I could try as I'm completley out of ideas of my own

Also could someone tell me the likelyhood of it actually needing the bios to be updated and if something is dead whats the most likely component

Very propably the BIOS issue. It needs the latest BIOS to support the E8400. Second in propability, your crap quality PSU is causing all this mischief.

Preferably get a bit higher, 550W model from Corsair, or OCZ StealthXtream 600W if you're low on money.

When I switched on my computer for the first time, nothing came up on the monitor... the fans were all working fine... but nothing else it seems... I just got a beep. What could be wrong??? HELP!!! >.<

Will switching the comp on to hear the beep again be bad for it??? Could this be a sign of shorting ect??

The 780i manual has nothing about trouble shooting this . The monitor is definetly turned on, the DVi cable is secured at both ends and I checked inside the GPU is getting power to it and is firmly seated. What am I missing .

Answer:Switched on Comp... Nothing but a beep

what is the beep? It beeps to tell you whats wrong, so figur out the beep pattern then google it.

Please help!Recently I've had a few problems with my PC, namely PSU problems and general system instability. I've changed my PSU and reinstalled XP and have half solved my PC instability problem - I'm now only using just 2gigs of ram even though XP used to run perfectly with 4gigs of ram. This solution worked well until today because my new problem is now my PC just won't boot up - there is now no motherboard ready beep or video signal going into the monitor. The PC has power running through it (fans and cd drives are working) but there is no mb boot up sequence so XP can't even start up.I've tried swapping out the ram and reinserting the VGA card but that hasn't helped. I'm now wondering if my recent system problems have been a symptom of more serious problem, specifically a faulty motherboard.Thanks for reading, and thanks for any help.

Answer:PC not starting - no m.board beep no video signal

Looks like the PSU again, or its popped the Motherboard and or CPU. The old PSU may have damaged the mobo parts when it blew. But I would still try a new PSU first

I have a computer that was working perfectly and after using compressed air it won't give a signal to the monitor, the keyboard doesn't light up (I'm assuming no power to the mouse either), and there is no beep when I start it. Internet cable lights up when I connect it, and the speakers make a "pop" noise like its receiving signal fromt the sound card. I tested the monitor, RAM, and graphics card on another computer and they seem fine...Fans are running okay and I removed the little circular battery from the mother board for half an hour to drain it, but still nothing.

Does this sound like a motherboard problem? I have a K9N platinum and if you suggest it is this, can you recommend a new motherboard (as this doesn't seem to be easy to come by anymore)? Hopefully its not the hard drive...

Thank you for checking this one out....and PS - baby steps are appreciated!

Answer:No monitor or keyboard signal, no beep on startup

Compressed air, not treated by difluoroethane gas or other static electricity preventative, is a very dangerous destroyer of computers... We have seen at least 12 computers destroyed by Compressed Air... one I did myself in my learning days...
Since then, we have run a lot of tests with canned air... All that are not treated are dangerous. All that come from a bench tank are just about guaranteed to destroy a computer system board, CPU, or other critical components...
And the static electricity can flow through several components before it finds a way to ground.

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?

No Post, No Beep. Bad MoBo?

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

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

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

Answer:help! no post beep

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

Question: One Beep on POST

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

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?

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

Hi to all, I have an IBM Aptiva E series 276, which has the AMD K-6 2, and the mother board is an Acer V75M. We have had this comp for at least 4-5 years, bought it brand new. I never noticed before because it is wifes comp, but was on it the other day, and upon startup, no beep code. Asked wife, and she said it has never made a beep on startup. I went to a beep code site for IBM, and it said no beep = power supply. Question is it`s been like this since new, and it is still running, if there is a power supply problem, why is it still running? Was wondering if anyone has run into anything like this before. I mean I hate to replace the power supply, since the comp is still working like it always has. Any ideas appreciated.

Hi All,

I bought my computer about 2 years ago from IBUYPOWER. Never had any issues. Will post specs after the story. So i used to have a GTX 580 but upgraded to a single 680. Then this past weekend i received a second 680(exact same). I was trying to get the hardware in but was having some issues fitting it for some reason. I had to get up and leave for a minute but wanted to make sure i didnt screw anything up (hardware was still not installed). Before i left it i turned my PC on and it was fine. Came back to finish up and managed to fit it and plug in the power cables as well. When i turned my computer on nothing happened. It seems one of the fans tried to turn on but it just stopped immediatly. No beeps nothing except for 2 leds that turned on and stay on as long as its powered up.

So far what i tried to do is just make sure all my wires are in correctly... however everything seems to be in place and nothing seemed to have moved... I am unsure what is causing this.

My specs are:
HAF 932 case
12gb corsair ram
1000 watt PSU coolermaster rated bronze
currently installed GTX 680 from EVGA 4gb FTW
I7 980
MOBO guerilla G1(the leds showing up are the ones right below the ram sticks)

I do not have much build experience but i do no this computer has worked flawlessly prior to this.
If any more detail is needed please let me know.

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.

Merry Christmas...

PC froze, Ctrl+Alt+Delete wasn't working, waited 30 minutes so I disconnected the power cord (on/off didn't work).

It now fails to boot. Turn it on, fans whirring, hard drive spinning, but no beep. Monitor displays 'no signal' (tried a different monitor). A couple days before it got to this stage, it gave me an blue screen (unexpected_kernel_mode_trap), but booted fine after that, not sure if related.

Keyboard and mouse both wired, both unresponsive (though they do power on).

Any questions, I'll try to answer as best I can.

Answer:Desktop fails to boot, 'no signal' from monitor, no beep

Just for future reference when your computer won't shutdown it is best to press and hold the power button for 6-10 seconds until it powers off.

Since the monitor is displaying the no signal message that means it is working. Your video card or video port is not sending a picture. I think I would reset CMOS and see if it makes a difference. Unplug from AC and remove the coin shaped battery for a minute. Then put battery back, plug in and try to boot. See if it makes any difference.

A couple of weeks ago the fan on my graphics card stopped working, it was buzzing a lot and periodically slowing down. I bought a new heatsink for the card, an Arctic Cooling Accelero L2. I installed everything on the card correctly and carefully. Now when I put the graphics card back on the mobo, the red light (the one ON the actual card, not on the mobo) is lit up and my monitor stays black.

The GPU itself worked perfectly fine (even if the fan wasn't working) before I installed this new cooler. I wouldn't use it much while the fan was breaking down so that it wouldn't overheat.

There IS a POST beep on power-up. Just a normal single beep. It recognizes there is a graphics card in my PCI-E slot but the card itself has a red light on it now. I tried swapping different SATA cables, even tried connecting the card to a molex instead. It just won't respond.

The fan on the new heatsink spins fine, however I have the fan connected only to molex power (it comes with a molex cable for direct-to-PSU use in case the fan connector doesn't fit the header, which in this case, it definitely wouldn't). I don't know whether or not that's an issue.

Now prior to all of this happening I had just contracted the Trojan virus Sirefef/ZeroAccess. I don't know if that would affect graphics card power settings.

GPU: Sapphire ATI Radeon HD5770 PCI-E 2.1

Answer:BIOS beep, PC posts, but red LED light on GPU and no monitor signal

Think you answered your own question,

The fan on the new heatsink spins fine, however I have the fan connected only to molex power (it comes with a molex cable for direct-to-PSU use in case the fan connector doesn't fit the header, which in this case, it definitely wouldn't). I don't know whether or not that's an issue.

Pretty sure the card won't initialize if there isn't a fan connected to the fan header. Are you sure that the connector from the fan won't fit on the card? From what I can see it has either a 3 or 4 pin connector (or both depending on which model it is) that should fit on the fan header on the card.

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.

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

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

I can only see the begining splash screen that says ASUS P6T Deluxe V2, after that initial screen, you cant make out much of anything... yikes!

I am trying to build a new system using my athlon mp-1200 or duron-1200 both are basically new and unused. 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:will not post - no beep sounds

could try reseating the vid card and also check the processor for any bent pins and then reseat it.

My memory isn't what it should be! Repeated attempts to increase it fail. The latest when booting I get 1 long post beep (repeated). 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. Yet a friends Pc same mobo works fine with it!

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

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

Answer:Continuous Beep After Post

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

Just seems a little suspicious.

Hi 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 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.

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.

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.

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...

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.

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.

Hi Tedster.

Sorry to hear you`re having major problems.

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

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.

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.

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.

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.

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?
