IMac 24 weirdness

My iMac 24 suddenly stopped working this morning. Now it won't boot up at all. I opened it up and noticed that the Number 1 light was on but none of the others were on at all. I believe the number 1 light is the trickle from the power supply right? Anyways the fan isn't spinning either. When I hold the power button in for 5 seconds and then release, then hit the power button again the fan spins 1-2 revolutions and then stops. If I don't hold the power button down for 5 seconds then the fan doesn't spin at all. I reseated the ram too and still nothing. Any ideas?
Thanks!!!!

It sounds like it's time to take it in for repair. You can try some basic resets but I think you have a hardware failure. First try restarting in Safe Mode if you can then try resetting the PRAM and SMC. If it still won't start there isn't a thing we can do for you here but refer you to an Apple Store or AASP.
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.

Imac Weird Clicking Noises

My iMac is making weird clicking noises when i first open a browser and continues sporadically with kinda screeching sounds. Also at start up I get a blue screen now? Has anyone had these similar problems out there and what did you do to fix them?

These clicking noises often come from the hard drive and may indicate that the hard drive is dying.
First, make a backup of your data with Time Machine or Carbon Copy Cloner onto an external drive. Then, open Disk Utility (in /Applications/Utilities), choose Macintosh HD in the sidebar, and verify the disk. What does it say? Also, you can check the SMART status in Disk Utility, selecting the hard drive at the top of the sidebar and looking at the bottom of the Disk Utility window.
If it tells you that SMART has failed or that the disk is damaged, take the iMac to an Apple Store or reseller to get the hard drive replaced

Imacs weird behavior

ok im new 2 apple macs so cut me sum slack if i get it wrong. right i have this mac one of the really, realy old g3 crts i think its either the imac 233mhz or the b version. i dont really know. i dunno the os or anything like that its new to me. you see the problem is when i turn it on it makes that noise from the speakers, and the screen comes on. BUT THEN a little file with a smiley face and a ?tion mark shows up and nothing hapens. it likejust stays with the icon in the centre of the screen. i need help please. also the keyboard lights dont turn on caps lock etc.

Hello and Welcome to Apple Discussions.
Getting the correct version of OS 9 in the UK is going to be a right pain. After that you need to upgrade the firmware, Install more RAM, replace the PRAM battery, upgrade the Hard Disk, locate a suitable copy of Panther (Mac OS 10.3) and install that. Only then will you have a vaguely useful machine. For far far less you can get an iMac DV on ebay.
Take this one for example. The Airport card alone installed in this machine sells for £80 second hand - so you could get an iMac and make a profit. The iMac DV has Firewire so you can connect large fast hard disk and Camcorders direct to the iMac. The iMac DV also supports the very latest Mac OS and takes desktop-sized RAM and Hard Disks and is significantly easy to upgrade.
Getting the 233MHz iMac in to working order isn't too difficult but the outlay on software/hardware probably isn't worth it for such a machine given the availabilty of better machines out there.
The lack of Caps Lock light could also be an indication of further issues.

Help! Battlefield 2 doesn't work on iMac 24"

Hi!
I have iMac 24" with nVidia GeForce 7300 GT, BootCamp'ed Win XP. So, when I try to start Battlefield 2 it crashes straight after the black screen. I suppose just before game's intro. I've seen there in discussions that BF2 works on iMacs with ATI cards or GeForce 7600.
To my surprise I can't find ANY info on this problem except for the list on EA homepage where GeForce 7300 is not included (neither 7600 is). There is not listed any video card of nVidia's 7th generation. There are 5th and 6th which obviously were previous to 7300.
I have installed all latest drivers and directx versions.
Any Ideas?
thanx in advance

Oh, need to add that BF2 works on my MBP but it crashes on iMac. weird...

Bootcamp display problems - aluminium iMac

Hi
I have an aluminium iMac and I have recently installed windows on it. Everything went fine but there seems to be a problem with the display driver?
What happens is that when I'm doing something, the computer seems to freeze (music lags) then the display goes black and the computer runs as normal (the music starts playing normally again.)
I thought it was only when I was playing Counter Strike Source but it happens when I'm not too. Is anyone else experiencing this? Any fixes/ suggestions?
I've tried repairing bootcamp drivers but to no avail.
Thanks

I was having Display Problems on my Intel 20" iMac- weird artifacts, lines, distortion of parts of the screen, weird color patterns, etc... all seemed to happen mostly during viewing video on the computer.
I worried that it was the card itself, and after about 4-5 years of use, was simply going bad-- and some articles and posts I found online seemed to confirm that this was possible--
I kept reading and eventually found posts about using smcFanControl to raise the fan rpm manually to try to keep things cooler in there... It seemed to work somewhat but not really, and the artifacts would continue and the computer itself was hot. The temp was usually constantly around 145F with lots of artifacts and distortion. When it wasn't running video or being used a lot, it would cool down and the artifacts would wane.
I found a step by step guide on ifixit.com to opening the iMac body to replace various components, etc. so I got the bright idea of opening it and blowing it out with compressed air.
It wasn't that hard to open and the guide was easy to follow, I went as far as removing the screen, which exposed one side of the guts and the fans. I blew it all out, it was dusty in there, and a lot of dust came out.
I put it all back and am running a netflix movie- temp is staying at about 125 +- and there are no artifacts...!!
I think I might have actually fixed it-- If you have a mac that is running hot and has weird screen artifacts, behavior, etc... I suggest dusting it and blowing out vents, fans, etc to allow it to run cooler....
Oh, My computer is way out of warranty, and I don't have AppleCare, and everything is backed up, etc... open at your own risk, knowing you will probably void any warranty.

IMac crashed, has a weird screen when I try to boot (which it doesn't). What's wrong?

My iMac 24" (model late 2008, I think I ran Lion or Mountain Lion) froze when I was working in Adobe Photoshop, so I had to manually (using the power button) turn it off and on again. Then, 5 minutes later, working in Photoshop again, the computer froze again. But when I manually turned it off and then tried to turn it on again, it wouldn't boot. The bootup screen freezes when the Apple logo is on the screen and the loading icon appears underneath that. Also, the display acts all weird, which is kind of troubling:
Close up:
Then I tried different keyboard combinations for booting. When I tried cmd + shift ("Safe Mode" or "Safe Boot" I think it's called in English) a loading bar appeared and it loaded all the way until complete. Just when my hopes were up, the loading icon above appeared and it froze again, only then with a different loony pattern:
Does anyone here know what's wrong with my iMac? And what I can do to fix it? FYI: I don't have Apple Care.
Thanks!

The graphics processor or logic board is failing and would have to be replaced if you want to keep using the machine. Apple would probably decline to service it because of its age. An independent service provider might be willing, but the part may no longer be available.

Weird lost access to iMac's desktop via Airport Extreme wireless LAN

This is weird and complicated. I'll try to keep it simple.
1. Two computers on a wireless LAN via Airport Extreme: G4 Powerbook and 20" G5 iMac. The LAN has worked flawlessly and seamlessly for several years, and except for this ONE anomaly, still does.
2. When logged-in to the iMac from the Powerbook, all its files and contents show up normally in it's networked-drive window in Finder,
3. EXCEPT the desktop. And I mean the real desktop which is under my ID under USERS.
4. Searching the Powerbook from the iMac, however, works just fine and shows all of the Powerbook's contents.
Repairs of Permissions on both computers have accomplished nothing.
There is one other peculiar symptom: there was a .wmv movie file sent me by a friend, and I had a copy of it on the desktops of both computers. It sat there, showed up and ran just fine, until one day something curious happened:
The file would show up in the column-view Finder window of the iMac's desktop when I opened it from the Finder Window, but would, after about a second, disappear!
If I try to import, on the Powerbook, some random file into the iMac's Desktop folder, it appears for a brief second and then the folder once again displays as empty.
I have trashed that wmv file, and yet sometimes its name blinks up on the iMac's desktop list (that is, again, the column view display in the Finder window).
This is profoundly weird.
Oh, and there's nothing changed or weird about the SHARING settings. Personal File Sharing is enabled on both computers, as is Printer Sharing, and itunes music sharing is also enabled. All of these continue to work just fine. Firewall is enabled, but always has been.
Owen

Well, when in doubt try all the obvious things FIRST!
I rank Disk Utility from the install disk, did a disk repair, and, well, Bob's your uncle, and all is fine again. Apparently that ghost file screwed up the count of files (I'm not sure what that means, but it seems consistent with a file that would materialize and then disappear, and screw up display of a folder's contents - the folder it was lurking-in invisibly.
Very peculiar, none the less.
Owen
I'll leave this open for another day, if only to see if someone has an explanation for what may have happened, since that might be useful to others, besides satisfying my own curiosity.

Weird display problem with iMac 24"

Hi guys, I have a very weird problem with my 24" iMac. For some reason it seems that after approx. 10 minutes using the Mac, whenever I keep a window on top of another window and then I minimize it, it keeps there like a ghost for another 5-10 seconds until it fades away slowly slowly.
Sometimes it's hard to see it however it's very evident when using a white window (such as Safari) on a dark background (not black).
I'm attaching an image split into 2 parts, the 2nd part is shot exactly after I minimised the browser. It clearly shows a faded ghost image on the grey Photoshop canvas.
Here's the pic:
http://www.neilazzopardi.com/imac.jpg
Has anyone ever experienced a problem similar to mine? or am I getting paranoid?
By the way, I bought this Mac, 5 months ago and I don't know whether this problem has been there from the beginning but I only noticed recently while cropping in Photoshop and still seeing the parts I removed away very faded.

den.thed it's not that I took it the wrong way or anything but shouldn't I be doing whatever I like with my iMac?
For the record that is a dark grey Photoshop canvas, which just happens to show the problem much more evidently.
The problem is that it happens on any background (even desktop) with any window, even Adium etc. Their ghost just stays there for a while... I use the iMac for design purposes and it's very annoying especially when cropping a picture and what I just cut out stays there very faded...

Weird screen pattern freezes iMac, can't boot from HD or DVD

I woke up today to find the screen of my iMac black with a sparse pattern of bright pixels on it. I wasn't able to power down holding the Power buton so I unplugged it and left it for a bit before plugging back in. I was then able reboot without any problems. Then a few hours latter a weird pattern appeared across my screen, kind of rolling, animated in spots as seen here:
I powered down, started it up and the screen had this pattern on it:
It froze during startup at the point shown in the photo with the Apple logo. I powered down, unplugged, plugged back in and then tried booting up from my Snow Leopard install disc. It also froze on the logo screen. Another attempt brought up the "You need to restart your computer…" message in different languages shown here:
I figured it was having a kernel panic so I did some searching around and followed instructions on The X Lab - Resolving Kernel Panics page and Apple's Kernel Panic Troubleshooting page. I unplugged everything but my mouse (wireless keyboard) and tried booting into Safe Mode. The screen still had the same pattern but it froze again during startup, the grey progress bar having disappeared.
I can't boot from my hard drive or from a DVD and the pattern is always on screen when I turn the iMac back on. I can't run Apple Hardware Test. I'm stuck but I'm wondering if anyone knows what the cause might be or has any suggestions on how to fix it or even get it to boot up somehow.
I have TechTool Pro and a large flash drive. I'm going to try creating a bootable USB drive with Snow Leopard on it from this backup computer and try to get TechTool Pro on it as well. I'll report back but I'd really appreciate any feedback on this problem.

Some things to report. First, the night before any of this happened, I noticed the fan was running when there wasn't really any reason for it. The computer was idle, no major tasks running. I'm wondering if perhaps the videocard overheated and is causing problems. Perhaps the temperature sensors are screwed up?
Today I got a USB keyboard hooked up and reset the PRAM. Still unable to boot but the pattern on the screen did change from the mess of b&w squigglies above to vertical bars as shown here:
Trying to boot normally or in Safe Mode both result in the spinning wheel freezing and halting startup.
I found powering down then gets weird. It's like it tries to turn on again but can't after a second. Or sometimes it will and the mouse lights up, I can hear the optical drive but the screen stays dark. At that point I need to unplug and try again.
I tried booting from Snow Leopard install DVD during one of these weird cycles and could hear it trying to access the optical drive but I don't believe it even got to the chime stage.
I attempted booting from the install DVD again after unplugging. No luck there but instead of a frozen spinning wheel, it brings up the "You need to restart message…". Other methods don't do this.
Still at a loss to find a reason for this but it appears to be a hardware problem, no doubt the video card based on the screen issues. Does any of this shed any light on what the problem is or (even better) how to fix it?

New iMac display problem(?) - weird colors and grain

Hello,
I'm a fresh mac user, made the switch this monday (August 27th) when my 24" iMac 2.4GHz C2D arrived. After using it for a while, I noticed a handful of dead pixels, and a semi-bright green stuck one. I thought I'd wait and see how disturbing I would find them before raising an issue about them.
Well, yesterday I decided to make my first backup of the whole system to my external 500GB Lacie drive (connected with FW800) using Super Duper!, which to my understanding is a reasonably sturdy and reliable backup application.
During the first backup iteration I started to notice some alterations in color in the top middle part of the display. I then returned to whatever I was doing (not on the mac, I had no other applications running, just Super Duper!), and after a while took another look at the display. The weird colored area had expanded, and the whole display had become somewhat grainy. Also, the backup process had slowed down quite a bit (from ~30MB/s to ~7-8MB/s).
So I cancelled the backup operation and logged out and back in again. No change. Then I restarted the whole system, which booted just fine, with none of the aforementioned problems. Even the second backup iteration went without problems.
Still, it's a new (and with my budget, quite expensive) computer, and if I get this kind of problem during the first week, I cannot continue using it happily in the fear of these problems reoccurring time and again.
I took a couple of pictures of this, one during and one after the problem. The quality of these are quite lousy, they're taken with my Nokia 9500 Communicator.
During the problem:

After rebooting:
http://iki.fi/aita/imac/02_ok.jpg
The images are taken in the same light conditions, but from slightly different viewing points. Note: The first image does not present reflections, it's how the screen looked (actually, in real life it looked somewhat worse)
What do you think?
Could this be a driver related issue or have I received bad hardware?
My drivers and Apple software should be up to date (at least OS X informs me that everything is, and I haven't found newer graphics drivers anywhere).
If anyone has had the same or related problems or know how I should proceed with this matter, I would be grateful.
Thank you in advance!

So far the only fix suggested has been to call apple and get a replacement. I'm still.....still waiting for mine to make it slowly across the ocean from China, so I don't know how the new one is working. I'd call Apple and request a new one.

I'm on a DD-WRT wireless internet service. Could this be causing my iMac to act weird ?

I'm on a DD-WRT wireless internet service. Could this network be causing my iMac to act weird ?

From reading this site and others, looks as if there could be thousands of possiblities/remedies.
I agree. Aside from the very remote possibility that running Java for that "trusted" website allowed some kind of infection--and if it was some kind of exploit, I doubt it would manifest itself in any way you'd notice--there are just too many different things going on for me to give any help.
Why were you thinking it was the router/DD-WRT? What if you connect directly by Ethernet?
Some generic thrings to try.
See if a Safe Boot helps. Shift at the startup chime and give it much longer to boot than normal. Don't open anything, leave it a minute or two and then restart normally.

You could try the shotgun approach and reinstall, but first you must be certain to have a completely reliable backup, in case you need to restore.

please help me

Hello nonnozeus
Welcome to Apple Discussions
That looks like the front glass panel needs to be removed for cleaning.
Your options are to take it to your local Apple Service Provider/Apple Store and have then clean the display and glass panel, if it's no longer under warranty then (DIY) Do It Yourself.

3 weird ALU iMac issues..

My ALU 20 inch iMac has 2 or 3 weird problems which I'd appreciate feedback on...
1. When I run Maintenance or Onyx they both said my start up has a problem and I need to install the original start up disk and have it repaired. I did so, it checked and said there were NO start up issues.
2. After shutting down for 3 days as I was away on holiday, I came back, started her up and there was the sound of the computer's drive being on but no start up process and nothing on the screen. I turned off for a while, did again, and on the third attempt it started up as normal.
3. Most weird of all, after downloading and watching a TV episode from iTunes, my dock disappeared. I put it to sleep and this morning it is still the same. I can only access Mail and Safari through the 'recent item's drop down menu.
Are these things connected? Why on earth does Onyx say I have a problem when the disk says I don't, and where might my dock be....?

Hello and thanks for your reply/
The Maintenance version is 1.2.0 and was just downloaded.
It says "the volume needs to be repaired. To repair your start up disk, start up from your OSX DVD..."
No more specific than that I'm afraid = start up volume?
Thanks.

New iMac with 1TB Drive - Weird HDD sound when spinning down/parking

Hi All,
Just got my 24" iMac and love it.
However after 1 day in operation, I noticed something weird about the hard drive (1TB Hitachi):
When powering down the system / putting it to sleep, the hard drive would spin down (obviously). The usual humming pitch would lower until there's almost no sound. However 2-3 seconds afterwards, there is this weird sound that scares me:
WOOOP... WOooop.... wooop... weeeep.. Sounding like the actual disc is unbalanced and slowly coming to halt... like a squeeking wheel only in much lower pitch.
The drive works fine in normal operation - speedy, relatively quiet (as to be expected with a 3.5" drive)... But this sound is really concerning me as I never heard something like this before.
Should I be concerned or can anybody confirm this HD model's behaviour as normal?
(I don't want to be stuck with a dead drive and lost data in 1-2 months)
Thanks,
Tom

I do not have the 1TB drive in my iMac so without hearing the sound it's hard to judge. I have heard drives make sound like you described and there been nothing wrong with it. It may just be the resonance from the drive spinning down. However like yourself I'd be a bit concerned as well. I would start by making sure you have your data backed up then run some diagnostics on the drive.
1. Verify SMART status- Open Applications/Utilities/Disk Utility select the drive on the left then look at the details down at the bottom. Or download and install SMART Utility: http://www.versiontracker.com/dyn/moreinfo/macosx/32454
2. Verify the directory- Open Applications/Utilities/Disk Utility select the drive on the left then click on Verify Disk.
3. Surface Scan- If you have Apple Care install TechTool Deluxe from the disk provided. Run TechTool and select the Surface Scan option. This will check every block on the drive.
If it passes all of the above I would feel fairly confident that the drive is fine but you still might want to give Hitachi support a call and ask them about it. If the noise still really bothers you call Apple support and tell them that the drive is making abnormal sounds and see if they will replace it.

Weird clicking sound, iMac freezes or is dead slow, and turns itself off!

I've had my iMac for a good 3-4 years, during which it has been fitted with a new hard drive.
About a year ago, during watching DVDs, there was a weird click-clack sound for a good 10 seconds which was followed by the freeze. Sometimes it would go off, but sometimes the Mac would turn itself off like it had run out of juice. I thought it might've been a power issue.
Nowadays it almost every time presents this clicking sound, and freezing is inevitable. Sometimes there's no warning, the power just goes off. I have unplugged all devices that are using power ie. iPod, but the problem persists.
Could this be a mere power issue? What can the clicking sound be a symptom of?
I'm doing back-up in case the Mac completely shuts down, but I have hope for the machine yet!
I have few months warranty left, keen to sort this out pronto! All comments warmly welcome.

As I was making the clone with SuperDuper, the process was halted by an error, and I found half of my stuff copied on the external hard drive. It had enough space, but it prompted a dodgy file in 'Frameworks' in the Library which stopped the process. It all looked very benign, and I checked the troubleshooting and it suggested to try again after restarting.
What in fact had happened, was that ALL my music files had disappeared from my hard drive, none of my applications would work on my Mac, even Safari or iTunes, and I was left last night with the blue screen of death. These files were nowhere to be found, ANY of the hard drives.
Ready to chuck the piece.
Thanks for all your advice but this time, it made it worse. I'm getting the Mac a new hard drive as it's still under warranty. As it's the third time I've lost my files, there's hardly a scratch on me.. Taught me not to get attached to things too much.

Firefox installs on my macbook air but won't open - this is weird because it works fine on my macbook pro and imac

I have an iMac, MacBook Pro and MacBook Air. Until recently Firefox worked fine on them all and was my default web browser. Suddenly and with no other indications, FF wouldn't load on my MacBook Air. The opening sequence commences but hangs up with a "loading" indication. I have tried uninstalling FF with CleanMyMac and reinstalling. All is fine until I attempt to open FF when again I get a hang up with the "loading" indication. FF is still working fine on my iMac and MacBook Pro. Weird or what!

I have that problem too! Have anyone figure it out?
Help!!
;)
