Screen is blank, making funny noise

I have the Imac G.4 plat panel. My computer was fine until yesterday when I turned it on, all I got was a blank white screen. Then it would make a clicking noise.....I do not know what to do??
I keep restarting and the same noise and white screen..
Please Help

If the eject button (or holding the mouse button down after the start-up chime to open the tray) doesn't work then there could be a greater issue than just the screen. If it goes straight to a blank white screen then your only option is to take it to an Apple Authorised Service Provider to have it looked at.
You may wish to look at this user tip (link) which looks at some of the options.
kind regards

CD / DVD drive making funny noises....

Not the most tech savvy of posts I know, but when I insert a DVD disc into my drive, it just whirrrs, and clicks, and after about a minute, spits it out.
Any ideas??
Thanks
MArk

The drive is making funny noises because it's trying to read the disk. If it can't read the disk, it will spit it back out. Try wiping the disk from the center out with a cloth to remove any fingerprints. Hope this helps!

Tecra A2: HDD making funny noises crashing laptop

Today, I turned on my laptop, got into windows, started working when my laptop made a funny noise, like a whoosh kinda noise, n thn my pc froze! i rebooted, but the same thing happened this time on the windows log in screen, i kept rebooting trying to make it work...until it didn't boot n now it just sits on toshiba screen before boot.
The HD LED no longer comes on and i'm stuck on the menu. I opened up my laptop n looked at the hardrive (tho did not touch cos i didn't wanna break it!) n its not loose or anything..but now i can't make it boot, i've tried the recovery cd which i can sometimes get into tho it doesn't seem to work!
Please can soemone tell me how to fix it, preferabley without sending it to Toshiba.

Hi Paul,
It sounds as if your hard drive has failed. Check in your BIOS during the initial POST to see if the drive is being correctly recognised.
You can try to restore the hard drive from the recovery CD (just boot from the recovery CD and follow the on-screen prompts) but this will erase all of your personal data and any programs that you may have installed and return your notebook to its original condition.
If you still have problems then I think you will need to replace the hard drive and re-install your system.

Problem with my iPod classic 160gb - making funny noises, and no download

Hi, At the same point every time i try to put music on my ipod classic 160gb, it begins to make a funny noise, and itunes and the ipod freezes. I have to disconnect it unproperly, and the message "The ipod disk could not be read from or written to", but my old music still remains. So i tried to restore the ipod on my macbook, but i still have the problem.
This is the 4th Ipod classic 160gb i have had, and there has been a harddisk problem with all of them, so this could be the problem, but the funny click-clack sound is new to this one.
Anybody in here have experience with such kind of problems?
Hope to get the problem solved soon.
Oliver Nash, DK.

Unfortunately, when a hard drive starts clicking that means it's going bad. The mechanism is having trouble reading the drive. Since the iPod is mostly just a harddrive and a battery I have a feeling that this is your problem.
watch this video. http://www.youtube.com/watch?v=wMm6c3fr-fU
about 25ss in is where the clicking starts. If it sounds like that, but softer and more muffled since it is a smaller drive that is being enclosed then I think you might be SOL. Maybe if you're iPod is still under warranty you can get a credit and go for a touch and avoid moving parts all together?

Ibook g4 won't go past gray screen, hard drive making whirirng noises

I think I'm in pretty serious trouble here...
I left my 2-yr old ibook g4 running last night downloading a couple of torrents, and woke up in the middle of the night because it was making a loud whirring noise. I tried to close everything, but found that it was frozen. So I just powered it off. I've never had it freeze on me, or otherwise had any problems with it before.
When I turned it on this morning, it would make the initial startup chime, but would not go past the grey screen with the apple. I tried several times, with a couple of slightly different results. The first time I got the apple with the circle underneath. The second time, I got no apple, but the circle with a line through it. And the final time, its just been the apple. And all the while, the hard drive is making a really ill sounding whirr.
I read another post about trying to boot from the install CD, so I inserted the CD & pressed c, but nothing happens, and now the CD won't eject.
Is it possible that it overheated? I got an e-mail about the battery recall, but according to my serial number, mine wasn't one that was being recalled.
Please help!
iBook G4 Mac OS X (10.3.9)

Haven't had any replies yet, but I do have some progress to report...
I was able to eject the Panther Install CD1 after all (pressed the eject button immediately after I powered on). Have tried booting from it a couple of times, to no avail. I was, however, able to boot it from my friend's Tiger Install DVD. I went into Disk Utility, as I have read elsewhere and tried to repair my hard disk using that, but got the following error:
"Repair disk failed. Could not unmount disk"
Probably a stupid question, but is it because its not the correct operating system?
I still don't know why it won't boot from my Panther CD.
I have tried to boot in Safe Mode, but all I get is a little folder icon that alternately flashes the finder icon & a question mark.
I purchased my ibook online when I was still living in Canada, but its no longer under warranty and I didn't purchase the protection plan. I am currently living in rural Japan, with absolutely no Apple Stores anywhere remotely close to where I am.
I've also seen elsewhere that I could probably just get a new hard drive, which is fine as I could use the extra space anyway, but does this mean I lose everything that's on my current hard drive??
If anyone has any suggestions, it'd much appreciated!

Fan borked? Making funny noises when it starts spinning up

All -
I'm fairly certain I have to take my PB in for service, but I'd like to verify that first, since my warranty expired two months ago.
For the past two weeks or so, every time I start up a video-intensive application (such as world of warcraft), the fan quickly spins up to high power. That's normal - but it's been making a high pitched buzzing sound that is definitely not normal. It originates in the upper left corner, at about the top of the speaker (which I disabled to verify it). Further, I run multiple desktops, and if I leave the game open but switch to another desktop (using Desktop Manager .5.3), the noise generally subsides in 10-20 seconds. This makes me think it's some sort of fan attached to the video card...? Comments? Thoughts?
Thanks,
Lance

I'm having the same issue, also due to World of Warcraft. I'm used to the fan being loud, but the high pitch sound you mention is definitely not normal. Honestly, it scared me so badly the first time I heard it, I think I actually jumped in my seat a bit. This was about a week ago.
I'm away at college, so with no means of fixing the problem at the moment, I started playing the game at the lowest settings possible (800x600 res, colors at 16-bit instead of 24, etc) That seemed to tame the beast, but only for a short time. In the past two days, I've attempted to start up, low settings as usual, but within a literal minute or two, the fan powers up and the strange sound begins.
I'm still trying to determine how I should go about solving this, (or if the problem is even rooted in the fan itself) whether it be via apple, or on my own, since my warranty also ended about 2 months ago, and I don't have Applecare.
It looks like you posted this a few weeks ago, Corbets... if you see this topic again, I'd appreciate it if you could reply with any information you gathered and/or how you went about fixing the problem... if you have yet.
Thanks,
Pam
Also, if anyone else happens across this topic, how much free advice and/or help can I get if I walk in to my local Mac store with my above problem... before they decide I need to start forking over some cash? I'm a bit nervous in that respect. As I mentioned, I'm currently away at college, and I try to save where I can.

Help! My movie is making funny noises!

I have encountered a problem with imovie 4.0. (on eMac) I have created an almost 20 minute softball video and burned it to DVD. Some of the "natural sound" is there and all of the music is there throuout the entire video. I tried to extract audio from the clips that didn't have audio in the video so the audio would be in a different clip pane. After exporting the audio and locking everything down, all of a sudden a sound swept through my entire video. It almost sounds like the audio is in slow motion or very distant static. I tried everythign in my power to settle down the audio but I don't know what else to do. I've spent over 30 hours working on this video and it would be painful to see it all go to crap. Any suggestions would be greatly appreciated.

Sorry, it has been over a month, I haven't been able to get back into school with summer vacation and all! I got the video to work on the DVD with all the correct sounds I wanted. I originally hadn't converted it to quicktime and just burned the iMovie with iDVD. After like an hour and a half, the quicktime didn't have the gross puking noise and everything is A-OK! Thanks for your help!

Hard Disks making funny noises

Dear Folks, got an odd problem.
Two weeks ago I was running two SATA HDisks - My Primary one being the SAMSUNG below and secondary being a Maxtor. The Maxtor started making this strange intermittent buzzing sound - it is discrete but because my desktop is right beside me I sensed it. It kind of when like this> bzzz .... bzzz ... bzzz ... bzzz after every two secs.
SO i thought it was the driver, Now I just bought a WesterDigital hard drive and lone behold it is doing EXACTLY the same thing. It can't be two fault Hard Disks in a row - especially since the Maxtor worked fine before my new build.
Any ideas?

Run the manufacturer testing tools.
If a harddisk is going bad, then it slow down your system to almost a halt.
It could simply be swapping of your harddisk making that sound, Windows does access the harddisk a lot, even when you do nothing.
I ran Western Digital's Data LifeGuard Diagnostics (Quick and Extended test). They both came up as a "PASS" - no more information than that.
What I don't understand is that it is the same problem with my MAXTOR and Wester Digital HD. That can't be coincidence surely?

Dashboard making funny noise?

Hi
Everytime i open Dashboard i hear this music, it has thunder noises this scary music with an evil laugh
i know this is random but i have no idea what this is, maybe some one knows what it is and how i can get rid of it, or how i could reset dashboard itself

Hello shorty:
You could try a couple of things:
Trash these preference files and restart:
com.apple.dashboard.plist
com.apple.dashboard.client.plist
If that does not help, I suspect one of the widgets you have downloaded has something imbedded.

Stuck at Grey Screen, Disk Drive Making Crazy Noises

My wife was using the 12-inch Powerbook (which had always run fine), when she told me a box came up telling her she needed to restart the computer (in several languages). She did, thinking it seemed "official." When she went to restart, the apple logo came on, and then the screen went light grey with lines across the screen. I was afraid maybe it was some sort of virus she got, but Macs don't get those, right?
When I tried to restart with the install disc (even pushing the C button), nothing happened. The disk drive made all sorts of crazy sounds, and I was brought to the same box telling me to restart in a couple languages. I wasn't present when the problem happened initially, so I can't say what might have caused it. After reading other threads, I'm very worried about my HDD. Could a HDD crash have brought that restart screen?
Anything else I can try? Or am I looking at going to the Apple store with a possible hard drive crash?
Thanks for the suggestions/advice.

Welcome to the Apple discussions.
You're getting a kernel panic, which is usually, but not always, caused by a hardware problem. This FAQ may help: http://www.thexlab.com/faqs/kernelpanics.html
When the disk drive makes all sorts of crazy sounds, that's usually an indicator that it's dead. If it's 3-5 years old, that's where they start to fail.
If you have the original OS X disks that came with your system, you can run the Apple hardware test to see if it confirms a hard drive issue. Insert the disk that says 'AHT Version x.x' in small print on the label. Reboot holding the alt key down, choose the Apple hardware test, and when prompted, choose the extended test. Does that give you any messages?

Ipod making funny noises and Sad icon

Instead of the normal hum of my ipod it hums for a second then makes a loud click and then hums for another few seconds then clicks again and so on. It also freezes up on songs and wont play songs. Then when i try to reset it i gets hung in a loop of the apple symbol then the sad icon or sometimes the ! icon. Waht is wrong??

Hi all,
I've been having the same problem, but found that a firm tap on the interior of my car door has rectified it. I'm not sure that Apple would recommend this solution, but it worked for me!
I'm wondering if it's anything to do with the latest software upgrade?
Cheers

Combo Drive making funny noises

My slot drive has been reading disks (both CDs and DVDs) fine, but whenever I insert a disk it makes a series of loud thunks, a few clicks and then a loud whir as the disk starts to spin. The whir continues the whole time the disk is in the drive. When I eject the disk it thunks some more, and I have to grab it right away, or it will get sucked right back in. However, there is no resistance when I pull it out.
My iBook is about 2 years old and the warranty has run out. I verified my permissions and reset the power manager, with no change. Does anyone have any ideas?
Thanks so much,
Elizabeth

I am having the same issue. Can anyone shed light on a solution? Or is a replacement in order?

Re: NB200 - Making noise and screen goes blank

Hi
My notebook is making pitched noise and the screen becomes blank. Please help with this issue.
Thanks

When that happens, does Windows still run in the background? Can you still see a faint image on the screen?
If yes, then the screen may be faulty (I don't think there is an FL Inverter since its an LED Backlit screen).
If no, then it may be the motherboard.

TS3274 My IPAD is on and is making the right noises as I am receiving emails. The screen is blank and I can not get it to turn on. I have tried to turn off and on again which is tricky when there is a blank screen. I have synced my ipad with itunes...

My IPAD has a blank screen. It is on and working because I can hear the ping of my emails arriving. I turned off and on as best I could which is tricky as the screen is blank. I synced with itunes and checked for updates. All ok.
Screen is still blank.
I can reset the ipad but I did this a month or so ago and it took forever and it lost all of my music which then took forever to get back on properly.
SO If I can avoid this I would.
Any help would be so appreciated!!
Thankyou

Try reset iPad (not Restore)
Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears
Note: Data will not be affected.
