My iMac makes a continuous beeping noise and a blank screen.

My 2007 iMac is making beeping noises and it's just a grey screen. Nothing is happening. I've tried to restart and unplugged it and still does it. Does anyone know what is wrong and can I fix it myself? Thanks

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

My iMac makes louder whirring fan noises and gets really hot.

Should I go to the service center and have it checked out?

Before you do, do a SMC reset and download and install iStat Pro (Google it) and post the actual temps.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Continuous Beeping noise on Startup and at other times

My iMac is over a year old. I have no idea what is wrong or happening here but below is what happens.
I hear a continuous beeping noise from my iMac at times. I had Firefox open and when it started beeping, a little search bar opened up at the bottom left of the browser so I assumed it was a sticky key on the keyboard so I pressed the spacebar and the beeping stopped and the search bar disappeared. This happened a few more times while I was using the browser.
The other day I started up my iMac and before it opened to the desktop it showed a small iMac HD icon so I clicked it and it started up normally, but then the beeping started so I just hit the spacebar and it stopped. Now I do remember after I turned the iMac on I accidently pressed some keys on the keyboard so this maybe why it showed the HD icon but I don't really know.
Yesterday morning I turned the iMac on and came back to hear it was beeping again. It was just a fast non stop beeping, too fast to count the beeps. It had loaded into the desktop so it was all good apart from the beeping, again I pressed the spacebar and it stopped.
Yesterday afternoon I got more beeping. Beeping is not just on startup it must be something else. I was using Firefox and was trying to scroll down the page, yet it kept jumping back to the top not letting me scroll down. This happened the other day when the beeping started. Anyhow I closed the browser and the beeping starts. I was able to turn the sound down and that got rid of the beeping, turned the sound up and the beeping still there.
I tried this so far...
unplugged keyboard and started up mac = no beeping
plugged keyboard in and started up mac = beeping
Again this morning I turned my iMac on, and beeping happened again, this time I clicked System Prefrences and the beeping stopped. I then clicked the Sys Pref folder red icon to close it and it made a different noise, but closed. I then opened up Firefox and went straight to my bookmarks to find a link, it wouldn't let me scroll down my list of bookmarks either, then the beeping started so I closed Firefox. Then I heard a loud sratchy type noise, it was much louder and hearing this has now made me think, something is not right.
Firefox version - 3.5.3
Mac OS X version 10.5.8
I don't want to set PRAM or those settings yet unless it's needed as I don't know what settings/network etc it will remove or change.
I appreciate any help:) thanks

When listening to nano 6th gen with dock the audio book will make beeping noises and then switch to a song.

While listening to my 6th gen nano on a JBL dock the audio book will make beep noises and then swith to a song on my nano. Any idea? Thanks.

I saw your other post, but thought I would reply here as well. It is all about getting that headset seated all the way. If you can see any silver of the plug, it is not in far enough. Push harder. If it just won't go in, look in there to see if it is blocked. The bottom of the headset port is white, so if it appears all dark at the bottom... something is in there.

Here's the Apple support article on beeps https://support.apple.com/kb/HT1547

HT1349 My computer won't turn on. Makes a low beeping noise that I've never heard but the screen doesn't turn on. The battery ran completely out but I've had it plugged in for 2 hours. Any thoughts?

I have a MacBook pro. After running the battery down, the computer won't turn on. It seems to cycle on but then makes low beeping noises and the battery indicator light blinks along with the beeps. I've had the computer charging for quite awhile. Any thoughts?

UPDATE:
My computer now works but still has the loading bar at startup. Here is some advice for other mac users with the same problem. To get the computer to turn on again (but unfortunately still have the loading bar - you will need to fix this problem seperately) follow these instructions:
Shut down the computer.
Unplug the computer’s power cord and disconnect peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
This is called a SMC Reset and will hopefully get your computer back up and running (at least for the time being!)
Good luck to all those iMacers out there!

Just installing a few updates from the Mac App Store for mountain lion on my 2010 MacBook Pro, during this it made a noise and then the screen and keyboard went off, like it is off. What happened, is it off...or should I just wait it out?

What kind of noise?
The only things I can think of that make noise are fans and disks. Fans usually will not cause the computer to shutdown as you describe. My guess is your disk drive died. I hope you made a backup prior to start the ungrade.

PC fails to reboot and shows blank screen after automatic windows updates including SP

Pavilion- a1130n" WINXP ProfessionalC fails to reboot and shows blank screen after automatic install ing windows updates including SP 3

I would love to say that a refresh worked for me however it did not.It takes about 30 Minutes total I was able to trace part of the issue to a Registry Key that was tagging the processor. Because my BIOS manages its own temp gauge and windows is trying to
build on in I had to turn the BIOS one off as well as for some reason I get better funtionality with Visualization off.
I am still dealing with a lag but I was able to get ride of the freeze that made the computer completely useless.

IMac makes a loud beep on start up, won't load past the blue screen and the black ticking dial appears every few seconds in centre of screen.

Urgent help!
Out of the blue my mac lost the mouse cursor even though it had connection so I rebooted only for the mac to make a loud beep on start up then get stuck at the blue loading screen. It won't load past the blue screen. I've tried to reboot holding down the shift key but no change. I've also shut down, unplugged the main for 15 seconds, re plug and wait 5 seconds before starting up again but no change. Does anyone have any suggestions?
PS: I'm not too sure which systems I am running without being able to check in about this mac. I bought my imac in January or February 2011 if that helps.

The power on self-test resides in the ROM of the computer. This test runs whenever the computer is turned on after being fully shut down (the power-on self-test does not run if the computer is only restarted).
If a fault is detected during the test, you will not hear a normal startup chime. Instead, the system will beep as explained below. If you experience one of these beeps, you may call your Apple Authorized Service Provider for additional troubleshooting assistance.
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable

Charger making a beeping noise and not charging.

Hi all, I have a problem with my 6 month old computer. The charger is making a constant beeping noise when plugged in and switched on.
It doesn't charge as well. I don't believe the battery has been overworked yet.
Has anyone any help, advice or tips please.
Thank you. Best regards, Sarah.

Hello
I agree with the user above. You should contact nearest authorized service provider to get a new AC/DC adaptor and let the guys check your notebook. Maybe this problem is related to the notebook too so you should ask for professional help.
If your notebook is only 6 months old, you will get a new adaptor for free I think because its a warranty case.
Good luck! :)

When my computer is playing sound, it makes a loud buzzing noise and the computer locks up

When my laptop Pavilion dv6 less than a year old, computer is playing sound, it makes a very loud buzzing noise and the whole computer locks up. I hit the lock symbol and then swipe my finger again to get out of the website (youtube) or close out the program playing sound or it will do it again.

Hi,
Shut down the notebook. Tap away at f10 as you start the notebook to enter the bios menu. Under the Advanced or Diagnostic tab you should find the facility to run tests on both the Hard Drive and Memory. Post back with the details of any error messages.
If both the above tests pass, try the following.
From the Start Menu, open All Programs, open Accessories, right click the Command Prompt and select 'Run as Administrator'. In to the prompt type the following command and hit enter.
sfc /scannow ( note that there is a space between sfc and the / )
Let the process complete, then type exit and hit enter.
Next, click the Start Menu, click Computer, left click Local Disc C once to highlight it, right click Local Disc C and select Properties. Click the Tools tab and then click the button to 'Check the Drive for Errors'. In the following window make sure both boxes are ticked and then click Start. Part of this process will require a restart to check the drive.
Regards,
DP-K

Battery w/a red line or bolt going through it and a blank screen- HELP

my phone was working and then I went to plug it in to charge, the screen went blank and a battery symbol with a red line through it came on. A Red LED light appeared. I tried to charge it for it was low but still nothing. I took the battery out and back in, charged it and still nothing. I had it charge all night and still the same blank screen w/battery symbol and red line.
do I need a new battery? what can I do to get my screen back and my phone working?? my phone was working prior to this.

Welcme to the Frums
Where did you get your battery? Make sure it is the correct one for your curve and I would take it back. Maybe it was an old stock battery?
