KT4AV Beeping at me on boot-up

I have looked that the troubleshooting guide.
Motherboards making a Siren-sound
If your board is making the sound of a firetruck, BEEP-BOOP-BEEP-BOOP...
Check the folowing:
1. CPU too hot
2. chassis intrusion was enabled in the BIOS
3. PSU is below min/max allowable value
My computer boots up and about 10-15 seconds later it shuts down and beepds at me. Everything inside is new so I'm stumped. Im still kind of new to whole computer building thing but I do know what works with what (Atleast I think I do).
1) CPU can't be hot, it hasnt even had time to heat up
2) Reset BIOS just incase. (Still beeps after 10-15secs)
3) I tryed a 400w PSU and a 300w PSU and both do this same thing.
Any other suggetions other then buy a new mother board.

Check to insure the heatsink is seated correctly, as they will fit backwards, but will not make good contact with the CPU. Make sure the cutout on the bottom of the heatsink is placed over the raised end of the CPU socket.
You would be surprised how fast a CPU heats up without the heatsink properly seated. Powering up a system with no heatsink can kill a CPU in under 5 seconds.

MacBook Pro will sometimes beep 3 times on boot

Shallah
Feb 9, 2014 3:09 PM
This problem started in late January and continues till now. The first time I took it to the Genius Bar the employee opened the back and repositioned the RAM. ( the laptop would sometimes beep 3 times on boot so he thought it was a ram problem). This made it work for about a day then it started crashing again. The second time I went to the Genius Bar the employee erased all my data, with my consent, and restored the makbook to factory settings. This did not help either as the laptop won't even let me use photo booth without crashing. I used to not power off my laptop and let it run in sleep mode for long periods of time. Also I move around with it a lot. What could be causing this issue and how much do you think I will have to pay to get my MacBook Pro fixed. It's a late 2011 model running mavericks and the latest updates. I do not have apple care and the laptop is out of warranty.
I am running osx mavericks. Never spilled anything on it. Have 4 gigs of ram.
MacBook Pro, OS X Mountain Lion (10.8.5)

In addition to BobRZ's advice, try each module in each bay. In rare occasions that is the problem, not the RAM.
Also download from Kelly Computing, Rember and run it overnight or longer. It is a good test to determine if you have faulty RAM or not.

The Tale of the Beeping Macbook - AKA- My Macbook Pro keeps beeping when trying to boot into Snow Leopard Disc's disk utility

Quick back story: about a month ago my macbook was falling and I caught it quickly, I had a game controller in my hand and it lightly hit it whilst I was catching it; the laptop made no contact with the floor, couch etc. Upon reveling in my epic matrix esque catch I noticed it was beeping and the screen was completely black - Horrified I held down the power button for a forced power down and then turned it back on to see that it was fine, along with no visible scars, dents etc to the chassis. Now flash forward to present day, and the macbook pro is only two months old (bought may 4th 2011) and I notice it's got some slightly irregular slow loading points when loading a browser, photoshop, etc. I do the standard disk utility to verify the disc and it says
"Checking volume bitmap.
Checking volume information.
Invalid volume file count
(It should be 537095 instead of 537096)
Invalid volume directory count
(It should be 161641 instead of 161640)
The volume Macintosh HD was found corrupt and needs to be repaired.
Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk."
So I put in the snow leopard disc to go to the disk utility within, reboot the laptop, and it goes to the gray boot screen with the dark gray apple logo and stays there whilst doing the aforementioned beep from my spider-sense catch. Does anyone happen to know what is wrong? Would that tiny tap from my controller when catching it have caused this problem I have now? Is there anything I can do at home to fix this since I can't get to the disk utility on the snow leopard disk? Will Batman ever get out of the Joker's trap? Or am I better off just making a genius bar appointment? Thanks in advance.
-ZRS

Are you using the Snow Leopard disc that came with that Mac? A gray disc that came with a different Mac won't boot yours, and a Retail (white) disc with a version of OSX earlier than the one your Mac came with won't boot it, either.
If you don't have the right disc, do you have an external HD, or can you borrow one?
(By the way, your post shows you're running Tiger; you might want to update that.)

MacBook beeping and no longer booting OS X after Boot Camp

So yesterday I used Boot Camp (under 10.5.3) to install Windows XP onto my Mac. I installed it following the exact instructions from Apple. However I was having problems installing the drivers. The install would always hang and never go anywhere. So I restarted and tried to boot to OS X, but it would just hang at the grey startup screen. No Apple logo or anything.
So I went back to Windows and got the drivers to work eventually. However my Macbook started making a weird beeping noise. It is very faint, almost sounds like a PC speaker on old DOS boxes. I had read that it might be harddrive related and ran a test from Disk Utility on the Leopard CD.It came up with no errors. By the way the beep happens under the Leopard CD when running Disk Utility, under Windows, and when trying to boot to OS X, so I think it's beyond the OS level.
Does anyone have any ideas on what might be wrong? Any help would be much appreciated.

Thanks for that clarification ...perhaps it's either the drive or the fan? Those are the only two moving parts that might produce a mechanical sound (and the optical drive as well). Perhaps even a weird vibration? There used to be problems with CPU whine, but that wasn't something that you'd hear as loud as what you're describing. I'd bring it in to your Apple tech. for a check over.

MacBook Pro 8,1 beeps 3 times on boot from FireWire drive: why?

Hi, all,
about the brand spanking new 13" I bought, I immediately wanted to boot the FireWire drive so I could install Snow Leopard. Install disk image was copied to a dedicated partition on the FW drive to speed up install process.
Holding the [alt] key during startup leads to 3 beeps that are indefinitely repeated. I also tried to select the relevant partition in the Control Panel Startup Disk. Same result
Why doesn't it want to start from this image? How can I solve this issue?

In fact, it is a late 2011, not an early 2011 "New Old Stock", so you're correct it shipped with Lion. But, aside from its weird ergonomics (Dynamically-attributed spaces and different gestures from the previous OS X versions), what turned me off was the official complete impossibility to get a physical copy of Lion at a reasonable price, when it is installed. I also wanted the mounted drives to appear at the top left corner in Finder windows, as they did in pre-Lion OS X, instead of the bottom left. I wanted to put back the Firefox profiles in their place... Turns out the Library folder isn't visible in Lion.
Simply put, anything I wanted to do to start on the good foot wasn't possible on Lion.
I went to the Genius Bar, and indeed their own external rescue drive also made the Mac beep. I told them about the Snow Leopard tethered downgrade. They were aware of the method, but there was no Snow Leopard Mac remaining in-store. And with the install DVD causing kernel panics, there was no way to at least try a dual-boot installation (Snow Leopard for mission-critical apps, Lion for playing around with).
To another Apple-approved place I went. The young tech here was willing to perform the downgrade (since it would have cost me $75/hr), and had both Snow Leopard and Lion machines. But I argued that I wouldn't be willing to pay twice since I intend to switch to SSD in a short while. He then tested when booted from a clone, and Snow Leo half-installed on the internal drive (needs one reboot during installation), but it ended up in kernel panic. Same went when he tried the physical Snow Leopard disk after formatting the internal drive, hypothesizing something detected on it may prevent Snow Leopard installer to boot. It immediately went into a kernel panic.
Both techs were actually surprised that this signal came out, instead of a message stating (official) incompatibility, as well as kernel panics.
My hypothesis is there's something in the Snow Leopard installer that accesses the hardware at a lower level during installation, but not during normal execution or Target Mode, hence causing kernel panics in the former.
What else can be tried, or what else didn't go through my mind?

RAM error beep when trying to boot install disc

I'm trying to re-install OSX in order to get a clean system and upgrade the OS. However, if I try to boot from the OSX Leopard install disc, I get the three RAM error beeps. I bought new compatible RAM (2x2GB SODIMM), tried with one of the old banks, then the other, in both available slots, then the new RAM - nothing helps: Booting the system with no install disc inserted works fine, having it inserted results in the beeps. It doesn't matter if I try straight boot, pressing C, using rEFIt or going for the device's own pre-boot OS selection menu, nothing helps.
I had the screen replaced on warranty a couple weeks ago, but I do not assume that poses a problem. Can anyone help?
Thanks!

Why do you have rEFIt installed?
To be able to multi-boot OSX, Win7, and Ubuntu.
What is your machine and what OS X does it have?
Early 2011 MacBook Pro 15" non-glare screen. 4GB stock RAM.
What's on the disk 10.5 or 10.6?
The disk is Leopard, as far as I can remember. I believe I got Snow Leopard over the App store.
Have you cleaned the disk, use another?
I don't exactly have another disc ... but I tried to image them to a SD card and that gave the same results.
What are you trying to do exactly?
Completely wipe the drive (low-level) to be able to sell the device.

Three 3 Beeps after long resume, boots into OSX just fine. RAM Issue?

Hi everyone,
After about a year or so of experimenting with Hackintoshs with the OSX86 community (MSi Wind and Dell E1405) and an enjoyable experience with my iPhone, I've decided to pick up my first Mac. I ended up with the newer Macbook 2.4ghz. As a veterened PC user who had no problems with Windows, I find OSX to be very user friendly, so this computer has been very enjoyable indeed.
I went ahead and upgraded it to a 500GB HDD and 4GB of DDR3 RAM as soon as I got it, and by this, I mean, I booted it up to ensure it worked, then shut it down, and added the new parts.
I don't remember if this happened on the first bootup when OEM spec, but now, whenever the computer has been asleep for a long time (after I get up in the morning, or when I get back from work), I hear three or so short beeps right before the DVD scanning for a disc. I believe this also happens if the computer has been turned off a while. If I restart or shutdown for a "short period" it does not happen.
I did some research online, and most people say the RAM has a problem, but they all never boot or have major issues.
My MacBook boots, detects the proper amount of System Memory in "About this Mac", and looks to be just fine in System Profiler. I also ran the Apple Hardware Test, and it passed without issue. The MacBook has no functionality issues that most people contribute to bad memory (reboots, funny screens). Basically, if it didn't beep 3 times, I wouldn't have thought anything could be wrong. The only other issue I have is that it doesn't turn on the laptop's display when resuming from sleep (which is very annoying), something others are reporting as well.
The DDR3 I got is OCZ Brand. A silly name, but reputable brand. It looks to use the same brand Micron chips as the OEM Apple. A link to the Memory I purchased is here - http://www.amazon.com/gp/product/B001CNR39U
Does anyone have any insight into what could be causing the MacBook to beep 3 times whenever I boot up after a long time of sleep/off?
Thanks,
Jonathan

Sounds like faulty RAM. Get 'em replaced. I tend to trust Kingston and/or Patriot for my memory needs.
If that doesn't work, then try popping in the stock RAM. If those work, then we know the RAM you replaced is still faulty. Keep retrying. If the stock RAM still beeps, send the machine in for repairs.
Btw, a running joke between my friends, we call OCZ ... OverClockZors =P.

Thanks

Hi there!
My computer broke down a couple of week's ago and i have been using my laptop meanwhile.
Now i finally got some new parts to my computer.
So the current computer:
AMD Athlon X2 250, 3,0 ghz, AM3, 2MB, 65W
MSI GF615M-P33, Socket-AM3, m-ATX, GeForce 6150se, DDR3, SATA II, GbLAN, PCI-Ex16

Kingston ValueR. DDR3 1333MHz 4GB, CL9, Kit w/two Matched ValueRAM 2GB DDR3
Samsung HD501LJ, 500GB, 7200rpm, 16M
Windows XP Pro 32 bit, right now, will upgrade later to Windows 7 Ultimate.
Huntkey Delcato PSU-422 450W DC Output: "+5V=35A(RED), 12V1=15A(YELLOW), +3.3V=30A(ORANGE), +12V2=17A(YELLOWBLACK), -12V=0.5A(BLUE), +5Vsb=2.0A(PURPLE), PG(GREY)
So the problem is that when i inserted all of my components and then just went to boot it, it gave me 3 beeps and a black screen.
My flatmate has the same motherboard and i tried the RAM, CPU and Video card on it, and it worked fine with one beep and i got a screen and came to BIOS.
I tried his RAM, CPU and Video Card on my motherboard and it still gave me 3 beeps and no screen.
So i have no clue how to troubleshoot anymore.
Tell me if you need anymore information
Please help me!
Thanks in advance!!

IMac 20in makes three beeps and fails to boot?

I have just changed the hard drive on my previously working 20in Intel iMac. The drive was pre-formatted and loaded with Mountain Lion using an external dock. The computer functions when fire-wired to another iMac, showing the doners desktop. Now I hear three intermittant beeps when pressing the start button on the 20in iMac. The screen remains dark. (It is assembled, but I have not fitted the aluminium front bezel or the glass yet). It does not respond to any keyboard commands. The memory moduls have been re-inserted firmly. Help please?

Sounds like a RAM problem:
Beeps on startup:
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images.
5 beeps = processor is not usable

Long short short beep code then no boot when trying to reboot???

I recently ran the recovery CD to get it back to factory condition and the same problems persisted (that I'll describe below) which indicates to me that there's some hardware issue. I've had the same issues before and after recovery was run.
When I start it, it often starts just fine as long as it hasn't been on for at least an hour. It seems to have memory management issues. It hangs up, gets bogged down easily, hangs, crashes, etc. It also seems to run hot. There are quite a few programs that I was able to run when it was working well that it no longer tollerates.
If I reboot after it's been running for a while It makes three beeps (Long short short). The screen goes black, the hard drive spins a little, but that's it. I have to turn it off for about an hour or two before it will actually start up at that point. Keep in mind, it doesn't start out at 100% and deteriorate. It starts out at about 40% of what it used to do and deteriorates from there. In needs to be rebooted about once a day.
Sometimes if it's hibernating, it will make the same beep code when I wake it up (Long short short) and most of the time it won't wake up from there.
So, can anyone tell me what that beep code refers to?
Has anyone else experienced similar problems?
Does anyone know which part is bad and if it's worth trying to fix it?
Thanks!

I am having the same problem....i do believe its a memory problem..??

B75MA-P33 3 beeps 3 times on boot

Hi!
I've just build my new computer (first time building a computer) and it's beeping when powered on. It makes 3 beeps 3 times. According to forum-en.msi.com/faq/article/bios-beep-codes it's "reserved", what does this mean? What could be wrong? Someone would help me out?
Thanks!
Santiago.-
Details: i5 3450, 2x4 GB RAM

Once you verify your system is running fine, (over a period of 2 months or so) you can pull the speaker plug from your motherboard. That way you don't have to hear any annoying beeps. Just be sure to verify the PC is running really well.

G4 mini: RAM 512 beeps 3 times, 1 GB beeps one time - No boot :(

OK, so my little G4 mini had 512 of RAM. I bought a 1GB DDR 333 PC 2700 2100 stick, which should be correct, right?
Well, upon installing, I get a single long beep and the front light flashes three times. I figure, badly seated RAM; try again. No solution there
Went back to the 512. Now it beeps three times and the light flashes four times! :((
OK, "maybe I destroyed something in the process?... Let's try going back to the 1GB" Same as the first time; one beep.
Go back to the 512; three beeps.
Anyone can help me figure this one out? If you need more details please just ask! Thank you in advance.

I read the Apple guides and it look like for after 1999 models:
1 beep = no RAM
3 beeps = RAM did not pass self test
Well, after many changes the 512 started working again, so I don't know what the problems is/was or how to solve it. I'll stay with 512 for now, I guess

Why does computer beep loudly and not boot?

I replugged in computer and turned it on. It will beep loudly with blank screen until I unplug it. Any thoughts? No changes other than unplugging it.

You may have a RAM Issue...

HP ENVY H8-1414 beeps at boot up due to the lack of a UEFI boot source

I recently messed up my Windows installation, due to this I ordered recovery DVDs from HP. Following the instructions I was supplied with, I inserted the DVD into my computer to try to boot off of it. It did not show up in the list of boot sources when I went to the boot menu. I then realized that this likely had something to do with me disabling UEFI boot and using the legacy boot option, so I went into the BIOS to switch it to the UEFI boot option. Now when I turn it on all I get is 6 beeps, which is because my motherboard is trying to boot into a UEFI OS, but there is not one available. So my question is, what should I do now? I can't change it back to legacy boot since that requires Windows (you have to go through Windows to get to the bios) and I can't boot into Windows because it doesn't recognize the reinstall disk as a UEFI enabled device.

COMPUTER INFORMATION: HP ENVY PRODUCT NUMBER: H3Z00AA#ABAMODEL NUMBER: H8-1414 Frank, I do not receive ANY error messages at ANY time. The monitor never comes on. The monitor and graphics card are good as I have chacked them in another system. The MotherBoard does not have on-board video. (Angelica 1.2) I receive 6 beeps, usually indicates video, and then nothing. However, it is not a video hardware issue. I am 100% positive of this as the video card worked previously and works in another system. At boot monitor does not turn on (I have tried multiple monitors and keyboards) I hit F10 and I get 6 beeps, then nothing.At boot monitor does not turn on (I have tried multiple monitors and keyboards) I hit F1 and I get 6 beeps, then nothing.At boot monitor does not turn on (I have tried multiple monitors and keyboards) I hit F8 and I get 6 beeps, then nothing.At boot monitor does not turn on (I have tried multiple monitors and keyboards) I hit F6 and I get 6 beeps, then nothing.At boot monitor does not turn on (I have tried multiple monitors and keyboards) I hit F2 and I get 6 beeps, then nothing.At boot monitor does not turn on (I have tried multiple monitors and keyboards) I hit F12 and I get 6 beeps, then nothing.At boot monitor does not turn on (I have tried multiple monitors and keyboards) I hit ESC and I get 6 beeps, then nothing.At boot monitor does not turn on (I have tried multiple monitors and keyboards) I hit DEL and I get 6 beeps, then nothing. I have tried every USB port on the machine using the same combinations from above.I have tried VGA and DVI outputs.I have removed the CMOS pin from one and two and placed on 2-3 and back to 1-2 after 10 seconds.I have removed the CMOS battery for 5 minutes and then replaced. I have tried placing a UBCD disc in the DVD drive for boot.I have tried placing a Windows 7 Enterprise dvd in the DVD drive for boot.I have tried placing a linux disc in the DVD drive for boot. This has to be a bios issue, I would think. My concern is two things. First, the keyboard does not seem to stay active during boot continuosly. Therefore, I am not sure if the system is getting a key command. I have tried several keyboards and even found a legacy USB keyboard from many many years ago. Same thing with all of them. The system does not have a PS/2 port. I have also tried using several monitors pulling out a legacy 15 inch VGA monitor to a new Dell 24 inch using DVI and VGA. I know the system is not bad and there is no hardware that is bad. I know this with 100% certainty. The system worked, but the harddrive was crashing (internal mechanical issue from within the harddrive). I removed the harddrive and connected to my other system to save data before a complete drive failure. After recovering 90% of the data, the drive completely failed. Therefore, the drive was pulled from a working system.
