Lenovo Think Centre Intel Q45 Motherboard POST beep code issue.

Question: Lenovo Think Centre Intel Q45 Motherboard POST beep code issue.

Hi, I have a machine at work which beeps 12 times (3 times, 3 times, 3 times, 3 times) then shuts down. When I checked inside there was no RAM it was discusssed that another technician had changed the RAM and I installed a new DDR 3 (1 Gig RAM module).
I now don't think it's the RAM but what else could it be I'm trying to find a good site for trying to identify the beep code, could it be the motherboard or CMOS?

I need help with this issue..A few days ago i was playing Sonic Generations on my PC and my performance was a joke it slows down it had problems playing smoothly and i had 4GB on my Vista 32-bit OS so i always found it odd why my computer was not as fast as the RAM promises to boost its performance so i decided to recap on my issue with the performance and i set it to a very massive Performance dedicated machine and still nothing so i thought back to several things that slow down PC performances and since i had Vista and i simply dont have the money to buy a Windows 7 or 8 "I wouldnt even if i had the money honestly..."So i also did things like open Task Manager to quit undesired running programs in order to dedicate more performance improvements.. this worked from time to time but i sure did not like doing it daily than i remember my last RAM stick "DDR2 1GB" was the last stick i placed in my Motherboard and the RAM was not matching the channels Soo.. i actually removed the old RAM that was in Channel 2 leaving behind 3GB of RAM and then i started playing Sonic Generations the performance was off the chain it was more smoother and ran nicelly but than i remember that the boot up said that the amount of memory reduced and that the RAM sticks did not match so i placed my DDR1s in Channel 2 and DDR2s in Channel 1 the performance was great i loved it sure it was not enough to play the game more stable but it was enough to fully play the game in 720p back than this was not possib...

My Dell XPS 13 (9343) has been non-operational for the better part of 4 months now. This is mostly my fault, as I was scared to bring it in for repairs, fearing a sky-high bill (my warranty expired in early 2016). I will describe the issue and I hope someone may have had my problem before or could offer some advice:
When the laptop is powered on, a yellow light facing the user (usually white to signal start-up) comes on and flashes intermittently. I don't know how to describe the noise that begins to sound other than 'an alarm'. Dell says it is a beep, I say a tornado is about to hit town. Whilst plugging my precious ear drums against this maelstrom, I count 5 beeps (months ago, when the problem had begun there were only 3 beeps *System board failure, says Dell online guide*). The guide I found online shows that this means a CMOS battery failure. 
Does this mean that I need to replace the motherboard? Or simply the CMOS battery? And since my warranty has expired, am I free to safely open the device and replace these myself?
Thanks for the help!

Answer:Beep Code Indicates Motherboard Issue - What to do?

Try replacing the CMOS battery first -- that will cost just a few dollars.
If that doesn't solve the problem, the mainboard needs to be replaced.

Morning all

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

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

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

Answer:Disable (post?) beep code sounds

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

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

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

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

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

Hi guys, this is probably the most helpless i've felt in a long while and i'm hoping you guys can help me out here.

So this is what happened,
1. I've been working on a very old HP Pavilion 6418 desktop which came with a Slot 1 PII - 400 Mhz processor.
2. Managed to purchase a Slot 1 adapter which supported Coppermine processors, installed it and things were going pretty well till this evening.
3. The computer is factory locked with a 100 Mhz FSB and I was desperate to get that up to 133 (to utilise the full potential of the 1 Ghz / 133 processor). Now the interesting thing to note is that the motherboard has only 1 of the 3-pin FSB (FS 2)terminals out of possible 4. The leads 1 and 2 are shorted out on the said terminal.
4. Having read a lot about overclocking and how easy it had been for some guys, I decided to experiment a little, so soldered the 1st & 2nd points of the 3 non existent FSB terminals section at back of the motherboard, i.e. FS 0, FS 1 and FS 3, and decided to take a look, if it was successful. Contrary to my expectations, the computer started but did not sound the system beep, on connecting it to the monitor, there was no display, system beep or the POST screen.
5. Then I removed the solders from the 3 FSB points and tried to check if the computer would come back to it earlier state. Sadly, this time too there was no system beep and when I connected it to a monitor, there was no video, POST screen, etc.

I'm hoping you guys can help m... Read more

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

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

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

Last Thursday my computer developed this issue.  It is a T60, purchased on 7/24/06 (warranty expired 7/24/09 gahhh) Anyway whenever I try to boot it up, the beep code of one long followed by two short is triggered.  The Lenovo site showed it could be memory, the screen, or the motherboard. I took it to best buy and they hooked it up to an external monitor, which had no effect, issue still occured.  They switched out the memory and the computer worked.  However, we re-installed my memory (which I had upgraded about two years ago to 2 GB) and the computer worked again.  ????  So it seemed the screen worked fine, as well as the memory.  I took it home and the next time I tried to boot it the issue happened againnnn. So when I hit the power button, all the lights (like Caps lock, battery, power outlet, etc) light up but then just the battery, plug in, and the circle Z looking power one are the only ones that are lit, and the beeeeeeeeeep beep beep is heard.  The screen remains black.  I'm thinking its the motherboard that needs replacing, but could it just be the video card?  Occassionaly, prior to this, the screen would shut off and stay black, but the hard drive would continue running.  I figured this was due to overheating or something, because sometimes it would get extremely hot. So has anyone had this problem before with the same beeps, and know how to resolve it?  How much does it cost to get a moth...

Greetings, I have an A55 8705-01U that I recently installed an Intel dual port Ethernet adapter into. This box is running pfSense and is a backup firewall. The card is an x4 PCI-E and I put it in the x16 slot. It worked fine, I booted and configured the card. All was well. Then, it randomly wouldn't boot. I wasn't near it at the time, so I brought it out and noticed that when booting I receieved a 4-2-3-3 beep code. Looking it up I notice that occurs when placing a graphics card greater than x1 in the (appearently fake?) x16 slot. This was according to support documents HT035838 and HT001908. Now, I don't particularly believe this. Since the card worked perfectly, but then suddenly quit working. My model number (8705) was also not specifically listed in the support documents above. Anyone have any idea if that's the case? Is this a fake x16 slot? Why did it work fine at first, then suddenly stop? Can the 4-2-3-3 code mean something else? Any guidance would be greatly appreciated!

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 just bought a intel desktop board DH67BL so I could update my rig. I put in a new i5 processor that matches the socket also. So I went ahead and put everything together and plugged it in to boot up for the first time and got a beep code. It's three beeps then a pause then three more beeps it continues in this pattern several times. Looked this error up in the book and it had to do with the RAM, I know all the ram sticks work because they worked in my old board that I am now replacing. But I went ahead and did one stick at a time in each slot and got the same three beep codes. The GPU is not in at this time, I left it out to make things easier for narrowing down the issue. After moving the ram sticks around I took out all sticks to see what would happen when I would boot up with nothing plugged in and got the same beep code. So how could I be getting the same beep code with nothing plugged in?? Processor is seated correctly I even unplugged the drives from the SATA ports to see what would happen and still nothing. I'm at a loss this is a brand new board and processor.

Hello.I have problem with my laptop Lenovo G580.I buy this laptop 3 months ago without systems. I have system Win 7 32-bit and 64-bit.Now i ahve problems with laptops and warranty service.Laptop turns on normally sometimes and sometimes not. ( If problems shows, i cut the power off, remove battery wait for few sec, and turn on, sometimes i must do it 3 times)It often happens that the computer will not boot just beeps.The video below, also sometimes blink window.Link 1: 2: thought that it is the fault of the firmware so I reinstalled Windows from 64-bit to 32-bit. It did not work. Flashing window appeared even when installing on a clean drive( second link, window blink on the beginning video), so I think it is rather not the fault of the firmware just the laptop PC hardware.I sent the laptop with cinematics to warranty service and wrote back to me that "after many hour tests, there was no problem" reset bios, swapped RAM and sent him back to me.Already two times I sent the laptop to them. Can you advise me what the problem is? What i can do to solve problem? Sorry for language mistakes. If need more information ples write in this topic.Please help. 

Answer:Lenovo G580 - Beep Code (Problem)

hi Arczi_Ghost,
Welcome to the Lenovo Forums.
From the first video, it looks like there's a problem with the Windows Loader or a system file that's needed to load but fails. Since you already re-installed Windows, this is most likely not an OS issue.
- Windows 7 Boot Process
From the second video, the flickering can be with the display (LCD) or wit hthe GPU / GPU driver. It's a bit early to tell without running some tests.
If you manage to boot Windows, can you try the following:
1. Install Lenovo Solutions Center and run a full hardware scan on the PC.
2.. Alternatively, you can also manually install the following and run a quick test on the unit.
- Lenovo Video Quick Test
- Lenovo Motherboard Bus Quick Test
- Lenovo Memory Test
- Lenovo Storage Quick Test
Edt: Fixed the links 
Let me know how it goes.

Really hoping someone can help me as I am pulling my hair out with frustration! Yesterday evening I opened a webpage that automatically opened and instantly closed a pdf page. Instantly AVG detected a Trojan Hider and attempted to quarantine but file was already unable to be found.

Windows Security Centre was turned off, Malwarebytes disabled, all webpages that offered support blocked and the install function of diagnostic tools prevented. Using the AVG log I used the details to locate the folder that had been created and deleted at source. This has allowed access to all webpages and to malwarebites (mbam log can be supplied) and ccleaner both of which I ran. Cookies deleted but nothing else of note.

Everything appears to back to normal, AVG and Malwarebytes coming up clean but Windows Security Centre still can't be opened. I have tried to change settings in services.msc but to no avail. Another forum page advised that remnants of the virus may be causing this (I knew they would be lurking) and advised that only software to pick them up was avast. I ran avast and three blockers were detected and quarantined but with no impact. I have since deleted avast as advised to only keep one AV and AVG is my paid provider.

I am sure that there is still malware hanging about but don't know how to find it or remove and still getting the error 'Windows Security Centre Cannot Be Started'.

Hello all,

I turned my computer on this morning only to receive a beep code in the pattern of:

2 quick short beeps, 6 long ones.

My motherboard is an asus p4p800se.

It should be known that I didn't install anything, I checked all the plugs in the back, removing and re-inserting them along with the pci slots and hdd cables. Of course I did this while the PC was off lol.

Anyways, what's the problem here?

Hey I'm having trouble with my Asus m2n32-Sli Deluxe motherboard booting up. After pressing the power button, the power comes on, drives get power, fans connected to the motherboard turn on, LEDs light up, but then the progress stops. Nothing ever displays to the screen and no beep codes are emitted from the PC speaker. The motherboard uses the Phoenix BIOS. I purchased a motherboard POST card and the code that displays is E0. I haven't been able to find good documentation on this issue or what should be done about it, although I saw something that hinted that it may have to do with the ROM or RAM, but it didn't indicate what action should be taken. Any help is appreciated. Thanks.

The XPS 630i motherboard failed (the Ethernet port and both PCI Express slots were not functioning).
I replaced the motherboard with one purchased on eBay and I used the CPU & memory sticks from the old motherboard, plus the GE Force GT640 video card and the hard drive with the previous installation of Windows7 on it, but then (due to health issues) it sat incompleted for a year. It just needed the waterblock and cooling system installed, which is just recently completed.
When attempting to start the computer, it plays a continuous beep for 25 seconds, pauses for 10 seconds, beeps again for 5 seconds, pauses again for 10 seconds, beeps again for 5 seconds, then stops.
There's no video display.
I realize I may have to reset BIOS / CMOS, yet with no video display, I'm seeking to respond to this beep's meaning, learn what that means first - and then generally how to set up this new installation from here. Thanks, Rob (archer5013)

Hey guys! I bought a y410p a while back. After using it, I placed it down for the night. The battery was low, but I am paranoid about over charging the battery so I didn't plug it in. I came back in the morning to find it dead. Nothing worked at all. No lights came on when I tried to charge it to anything. Tested the power supply with another laptop and it worked. Me and some friend tried the power button thing and still nothing. I gave it to my friend to check out and he said it looked like it was dead. Fast forward 3 weeks. After being on vacation, I just got it back and the charge light comes on and it turns on (can hear/see fan running and keyboard turns on, but it makes a beeping noise. It sounds like it's a long beep then astop/pause then a continuous beep. What's wrong with it???

Answer:Lenovo y410p has strange beep code after it appeared to be dead.

Try clearing the CMOS by doing this.......
1. Unplug the charger / adapter. 2. Remove the battery. 3. Press and hold the Power Button for 15 seconds. 4. Re-install the battery, plug in the charger / adapter if needed and power up the system to see if the problem was resolved.
If the problem continues..... have you tried removing the main battery and then try powering up the laptop just using the charger / adapter as the power source?

I have an issue with startup, every now and again my startup initiates what sounds like 2 long beeps followed by 3 short ones - 'beep-beep' + 'beep+beep+beep' - but from what I've seen, throughout online discussion, it is only 1 long beep followed by 3 short ones. After this tune is played my screen remains blank, and on another attempt of start up the PC runs fine. Any ideas?

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

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

As the subject says, I'm in the market for a replacement motherboard for my T61, as it seems it's taken a permanent vacation after a spillage of soda over the palmrest. Seems the only solution is to replace the motherboard. Of course I could spend some more money on a new computer, but I've spent quite a few $$ on this one already, and I like the screen and the 4:3 aspect ratio, and the overall quality of the machine - so... does anyone have a spare motherboard they want to get rid of? I'm also looking for a replacement palmrest, with room for the fingerprint reader, for the same computer, as one of the lid-catches have broken, and the lid doesn't close properly.

I've got a 3-year old Alienware Aurora DDR system:
AMD 2800+ chip
ASUS A7N8X Motherboard
2xInternal 7200RPM HD's - 1x120gb, 1x200gb
"Radeon 9700 pro" (hercules 3d prophet)
DVD-R drive, DVD burner drive
assorted PCI cards, wireless card, firewire, DSL adapter, etc...

When powering up, the system miserably fails POST. It won't boot into DOS or windows, hangs immediately after the hard drives and fans spin up. That first 'beep' that signals all the hardware is working properly never happens.

I've tried everything I can think of to locate the malfunctioning device, I've disconnected/reconnected each device individually and powered up/down - it appears that the problem is with the motherboard or CPU.

I did have an overheat issue 2 years ago associated with a burned-out CPU Heat sink fan, where part of the plastic casing between the heat sinks and the CPU melted, but has caused no issues, potentially until now.

Prior to failing, the system never showed any signs of problem at all, was running fine.

Any suggestions? (i'm thinking i'll need to replace the motherboard, but before I do that I wanted to know if there was something I could check, jumper settings, etc...)

Help is much appreciated,

I'm building a PC with a brand new Asus Crosshair V Formula motherboard, 8gb DDR3-1333, AMD X6 1100T processor, Samsung 64gb SSD for C: and a 1tb SATA drive for storage. Anyway, when the cable for the front audio on the case is connected, the motherboard will not POST. No video, no beep. As soon as the cable is disconnected, everything is fine. I changed the BIOS setting from "HD" to "AC97" and connected the AC97 connector from the front audio cable and this worked for about 3 or 4 reboots, then it stopped POSTing normally. I'm going to look at a possible BIOS update, but I can honestly say, that after building over 300 systems in the past few years, that this is one of the strangest POST problems I've seen.

Any ideas on why the front cable would prevent the PC from running normally? There's nothing plugged in to the front headphone & microphone jacks, so the cable shouldn't matter whether it's connected or not, right?

Weird :confused

Hey, dlb...

That is a strange one - those kinds of symptoms that can make you go nuts...

I wonder if anything is wrong with the jacks themselves - grounding to the case, shorting together, etc...are they built into the case, or are they mounted in an enclosure?

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.

Hi guys,

I have an Asus Z97A Motherboard/GTX 1080/24GB DDR3Gskill/ 500 GB SSD + 1to HDD and recently when i boot my PC i hear 1 long beep then quickly after 3 short beep.. I've searched in Asus website about the meaning of these beep and it's written that it's a Video card faulty..

But well just after these beep my pc is booting well ! and video card working well too, i've no problem playing games.

The strange thing also is that it's making these beep like 1 time every 2 or 3 days as i shut down my pc every night and when i'm going to work.

Do you have an idea of what i can do ??

The symptom:
All fans (case and CPU) will start spinning at power-on, CPU fan will spin at high-speed and then slow down over a period of about 3 seconds, system will not beep, displays nothing on screen, will not POST, enter BIOS or boot. Pressing the reset button does nothing. I have to hold the (case) power button down for 5 seconds to power-off or use the switch on back of PSU. If the case power button button, the system will sometimes restart by itself.

Intel Haswell I5-4440 CPU (box)
Kingston 8Gb DDR1600 + Kingston 4Gb DDR1600
Gigabyte Green Power 550W PSU
Cooler Master K380 ATX Mid Tower

I bought a new motherboard, only to find that that did not fix the problem. I replaced the 4G RAM with an 8G DIMM, which also did not resolve the symptom. I've since noticed that unplugging 8-pin CPU power connector to the motherboard, letting it stand for a few minutes and then plugging it back in and powering-on will result in the PC booting normally once, with all subsequent starts failing again with the same symptom.

Is there a way to easily troubleshoot the PSU and CPU to isolate the problem ?

I have a custom built PC with an Asus M5A78L-MLX motherboard.

After installing a Sapphire Radeon HD6770 1 GB DDR5 DVI/ HDMI/ DisplayPort PCI-Express Video Card 100328L my computer wouldn't even POST. If I remove the card then it works just fine. The video card had power and was pushed all the way into the PCI-Express slot. My BIOS should be up to date as of December-2011. I have not had any other video card installed on the computer before and have only used the motherboard's built in video capabilities in the past.

I was thinking it may be a conflict between the card and the motherboard and was wondering if there is anything I might do to resolve the issue. The video card's instructions mention that I should disable the motherboard's on-board graphics capability prior to installation but I cannot find anything in the mother board's manual about how to do that.

Any suggestions would be much appreciated.

Answer:Radeon HD6770 wont POST, maybe a motherboard issue?

Welcome to Windows Seven Forums.

Have a look in your BIOS settings - I think this route should get you there:

Bios>Advanced>Chipset Configuration>Internal Graphics>Internal Graphics Mode>Disable

Your computer manual should tell you which key to press to get into the BIOS when you boot your computer.

Answer:Intel DH67BL Motherboard Issue

I'm not sure I understand what you did.

That MB has one (blue) PCI Express 2.0 x 16 discrete graphics card connector, two (black) PCI Express 2.0 x 1 connectors, and one (white) PCI Conventional bus connector.
So I am confused by the statement: "so i plugged it to internal video slot and its working fine ". Maybe you could explain this better?

The MB specs say it has integrated graphics, which I assume is the graphics on the i5 processor. Have you tested that?

And, how did you clean the machine? That may give us some clues as to what could have happened.

This is my first homebuilt rig. I have an Intel D915PBL motherboard with a 3.0 processor. I've been very pleased with the motherboard, except for one nagging problem that has me a bit concerned.

As this processor runs hot for me, I want to use Intel Desktop Utilities to monitor the temperature of my system. I had it all installed and everything was up and running, and then I started getting an error message that said:

"Connection to hardware sensors failed. Click YES to restart application, or click NO to close application. If problem persists after restart, please reboot your system."

I only get it every once in a while when I have the desktop utilities open, but it is kind of annoying. So, I started to look into it a bit more. The name of the service that runs the hardware checking is IDUServ.EXE. I looked in the event viewer and noticed that there were several instances where it was starting and stopping. So, I rebooted and watched for it in task manager. Sure enough, when first booting, it kept appearing and disappearing. After about five appearances/disappearances, it stays put, and the desktop utilities works. If I leave the utilities open though, every once in a while, the connection disappears again, though the service does not actually stop (as seen through the event viewer).

Hello and welcome to Techspot.

It could just be that the software for the intel desktop utilities isn`t very good.

You said that the Everest programme works ok. Again this is a clue.

Maybe you should try the speedfan programme from, and see how it performs.

If that also seems fine, then it`s got to be the intel programme itself.

If you aren`t having any problems with the system itself, then that`s a sign that everything is ok. What temps are you getting?

I recently purchased a refurbished T410 as I always have been interested in Thinkpad's for a while and felt it was time to take the plunge. I have been using it without any issues until I installed Lenovo Update and once I installed it I let it do its thing and update all that it needed to one thing being the BIOS. Once everything updated and it restarted itself I was at my desktop and I could not get a wireless signal only to find out that my wireless adapter wasn?t even being recognized. I pulled up device manager and looked into the issue and saw that it has a Code 52. This message followed: Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52) After doing some research I found out that upon boot you can press F8 and boot into the Windows advanced boot options and select "Disable Driver Signature Enforcement." Once I did this the problem was solved but here is the kicker, this is needed to be done every time you power on the T410 from shut down. Has anyone encountered this sort of problem before or can help me and point me in a specific direction to help fix this issue?


Go to Solution.

Answer:Lenovo Update installed on T410 now have Code 52 on Intel Wireless 6300 AGN adapter

I figured out the problem and long story short what I did was basically go into the device manager find the wireless adapter and then highlighted it.Once it was highlighted I right clicked it and selected uninstall.Then I restarted my thinkpad and upon restart Windows 7 automatically reloaded the drivers to it and then it was back in action and is now in working order.

So I bought a new Lenovo Y5070 laptop yesterday without an operating system since I still have my windows 7 64-bit. Windows 7 64-bit installed without problems. By the time I got to installing my drivers I couldn't get through with installing my Intel Video Driver, therefore couldn't continue to install my NVIDIA driver either. I downloaded all compatitable drivers from Lenovo Support section. When I try to install the Intel Video Driver that I downloaded from the support page, it gives me an error saying: "This computer does not meet the minimum requirements for installing the software." Here are the specs for my laptop - If anyone knows how I could resolve this issue let me know.

I had the same problem. You can download the Intel driver directly from Intel. It works and it is newer than the one that comes with your system.You're Looking for 4th Generation Haswell with HD 4600:

I have two hdds and a usb all having the same issue. The first drive is the one that came with the laptop. It still has the same w7 partitions and everything. It has not been changed or modified It's a 320 gb western digital. What happens when I boot is it gets to post and then takes a really long to get past post...if it will at all. Once it gets past post and 'catches' the bootup in to windows is normal and so is function as far as I can tell. The second drive is a 1tb western digital that I installed ubuntu studio on. A few months in, I began to I get ata system bus errors.  I don't exactly remember what the exact error was. It's recently gotten worse such that it won't even detect the 1tb drive.  No boot up at all. The third drive I have tested on it is a usb stick/thumb drive/ that I have various linux iso's on. I also have ubcd and some other tools. I installed the iso's to run as live OS's using yumi.  This drive has a similiar problem as both of the other two. It takes a long time to get past post and once i get to my choice of OS's that I can boot in to, it takes a long time to 'catch'. Once it does, I will some times get the ata errors and get similiar to the ubuntu 1tb drive...but it has not failed completely. I've run the western digital tool data life guard full test (it took overnight) on both drives and there are no errors, so I think the drive is okay. What the heck is goin on?

Answer:Lenovo G575 4383 Motherboard/Boot issue

hi jesusatemybaby,
Welcome to the Lenovo Forums.
Looking at the system boot process, the "ATA system bus" error that you're encountering is possibly due to the CPU/mobo that's not properly initializing hardware components (which explains the long wait times during POST).
One way to verify this is to run a diagnostic on the CPU/Motherboard by using Hot Cpu Tester or similar utility. If you get errors, you may need to consider getting the unit serviced.

Hi, I bought a new G50-45 (from the US), and soon after I started using it, it began to seemingly randomly restart (like a reset button being pushed on a desktop).   I tested the memory using Memtest in the boot menu.  Everytime I'd test the memory, it would restart in the same way after varying levels of testing time.  I tried Memtester for Linux as well, which also prompted the resetting. Next, I tried brand new RAM from the store (the correct type for the machine) and it still reset.   I took it to a technician and they tested the hard drive, and said that it (the hard drive only) tested ok.  They did not determine the cause of the resetting. I also ran a bios update a couple weeks ago, which was successful. Can I conclude that either the motherboard or cpu is bad? Thanks for reading, and as an aside, could someone tell me if there is a service center in Ecuador (where I currently am)?  I'd rather not have to mail the machine.

Answer:G50 Lenovo Restarts During Memtest, Hard Drive Tests Out Ok. Motherboard or CPU Issue?

hi there,
I checked your system G50-45 (80E30181US) and it's possible that the motherboard or the CPU (which is soldered to the motherboard) is causing the restart. Heat could also be a factor in causing the constant restart.
Inside Windows, try to monitor your temps while the system is under load and see if it restart at some point. You could also run a CPU/GPU test to determine while monitoring the heat and see if the machine restarts.
- Lenovo Individual Diagnostic (see CPU Test)
- Heavyload (sample CPU/GPU stress test tool)
Temperature checking:
 - AMD Overdrive or under the Catalyst Control Center
 - CoreTemp (CPU)
 - GPU-Z (GPU)
 - HWMonitor (CPU/GPU)
As for the service center, looking at the International Warranty Lookup page, you won't be able to have the G50-45 serviced in Ecuador as it doesn't have an international warranty there.
However, if you'll be travelling outside Ecuador, the machine can be repaired at the nearest country (as per this site, it's Colombia).

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?

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?

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.

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?).

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.

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)

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.

A couple of days ago, my PC started to restart during the boot-up sequence. The lights flash on the HDD and CD and DVD and then the machine restarts again several times before getting to the POST beep. Once the POST beep has sounded then Windows XP loads as usual.I have checked the connections inside and outside the PC but have not reseated any cards or cables yet. Does this restarting point to a specific component failing? Any help would be great! ThanksPC: OS Win XP Home Sp1. CPU:AMD Athlon XP 3000 2.2GHz.

Answer:Restarting before POST beep

I suspect that as this is happening before anything gets properly loaded that it's something connected with the power supply unit not kicking in properly.

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...
