When I power up my iMac, I encountered a very loud fan sound in the background that I had never encountered before.This happens despite turning off and powering up again.

I've had problems with my Mac for a while now. First of all, it indicated ram problems with 2 beeps. I later fixed this by moving and changing around modules. It was solved, but now a new problem. The Mac seems to turn on, making its iconic sound for startup, but the screen remains black. After about a half to one minute, the fans go crazy and I have to shut it off. I've tried a few things like holding shift or alt, but that doesn't work as it doesn't even display a white screen.Â
I need to know what to do and I don't really have the time to buy new parts right now. I'm really a windows based pc fixer by the way so I'm new to fixing macs.Â

I just bought my MacBook Pro last week. When I power it up, it makes a loud noise for about a second and a half. I think it's the hard drive starting up or the disc drive. I'm not sure which one, but it's pretty loud, so I was just wondering if anyone else noticed this and if it is normal.

I just bought a new 24 inch 2.66 GHz iMac off of MacMall last week (6 days ago) and it has been working fine up until a day and a half ago. You see, I put the iMac to sleep for a while, and when I woke it up there was a moderately loud (but in no way ear bashing) grinding/whirring sound coming from the left area of the machine under the screen. I now noticed that the longer I have the machine on for, the louder and more annoying it gets. Does anyone know what is there (HDD, fan or what)? Also, is this something I have to worry about or is this an issue all iMac users face? I am new to OS 10.5 and modern Macs. I am really starting to get worried about this, as the machine is almost brand new.

20091009 175820.m4a - 3.78MB OR (in case the first one doesn't work)
When I click on the built-in mouse (whatever it's called), it's a lot louder/snappier sounding and feeling - makes more of a loud clicking sound - then my old Powerbook G4 did. Might I have got one that's a little out of whack or are they all that way? If it's normal, why so "clicky?" These days aren't they able to make things softer/quieter? I also noticed how sharp one of the corners is in the area where the latch (or lack of) is...that center area where you lift up the lid. I like that much better than the old one but does anyone else have the problem of a corner being too sharp?

My G5 has been making more noise at start up. It sounds like one of the fans is making a grinding "rrrrrrhhhh" noise. My living space if very cold and quite dusty (warehouse). I notice it more on colder mornings ( inside temp 45° - 65°F ). Should I refrain from using my machine on cold mornings/nights until the heat is running?

I just got a mac mini on thursday, went on a small trip on friday-sunday. When i came home to my sleeping mac mini and woke it, it made a TERRIBLY loud fan clicking noise. My old PB 12" made this noise after I had dropped it on floor from about 3 feet. I didnt drop my mac mini, i barely used it for 2 hours before i had to leave on my trip. The sound eventually goes away though, once the mini heats up a little i guess. So i'm pretty convinced it's the fan, but why would it suddenly do this?
I was browsing a webpage with Safari when suddenly this really loud screeching sound came from my Macbook Air. I am not talking about the small clicks the HD seems to be doing once in a while. This was a very loud screeching sound, like someone cutting glass with a diamond. I didn't have any other programs on and my speakers were off. The sound lasted for about 2 seconds and got me very scared. I immediately checked the temperatures and fanspeeds but they were all normal (CPU around 45 celcius and fan about 2500 rpm). Now I'm afraid that it was my HD and it will fail on me sooner or later. Everything seems to be work normally now but I already sent all my important documents to another computer.
View 24 Replies View RelatedI recently purchased a 13" 2.26 stock macbook. It's perfect, screen is good (no scrolling issues or purple blues) with no dead pixels, no slanted keys, and no scratches.
I updated the firmware that addresses the SATA 1.5 issue. After the update, I reset PRAM. I held down the buttons till I heard the second or third startup bong.
Here is where it gets funny.
Now, when I reboot or start up my computer, the start up noise is loud. Even with headphones plugged in and also the volume turned to its lowest setting (even with volume turned off). Eventually, to control the startup noise, I had to install the startupsound program in my system prefs as mentioned on other threads and that has seemed to control the startup sound.
I was wondering, if by resetting the PRAM if I have harmed my computer in any way. Should I be worried about deeper issues with my computer since the startup sound was not previously being affected by reducing the volume to zero with headphones plugged in?
I want to tighten the touchpad so it doesn't sound so loud whenever I click on it. But I can't find the correct size allen key for the battery screw. Does anyone here know what is the exact size for the screw for the battery and what type of screw driver to adjust on the touchpad? I know I can use a flat head screw driver, the main part is to get the battery out of the way.

2 days ago i received my new mac pro 6-core 3,33GHz...now something really weird and super annoying is going on with this computer...From time to time there is this really loud POP trough my speaker. I'm absolutely 100% sure this has nothing to do with my amp. cables or whatever and its definatly a problem with the MacPro, i know because of the following:
Plugged in new cables, removed every installed software, plugged onto different amplifier, when there are absiolutely no audio cables plugged into the computer and when i use the build in speakers of the mac pro i still hear the POP/distortian like sound, and finaly even took it at my friends house and tested the machine there on his audio instalation...problem remained! not knowing what to do next i decided to go and see a very good technician (music instruments and studio recording) and told him about the problem, he imediatly stated that it "could be" because of the harddisk drive giving like electric impulses or whatever that causes the distortion...or that the sound card or audio chip set waking up from sleep and every time it does there is this loud POP?..................
It happens when the MBP wakes up from sleep. The longer it sleeps, the louder it's. Listen for it after the 1st 10 second.

My macbook pro has never made weird sounds. It is 2 and a half years old. It has been dropped twice, but not recently at all. Upper left side of macbook pro made very loud scratching sound as I opened it from sleep. It only did it when I had the laptop at a certain angle. It is still doing it. Im currently backing everything up to an external hard drive. I'm very worried. It was very loud, not the fan, not the usual disc slot movement, not the speakers.
View 5 Replies View RelatedOver the last year I now and again get this strange this happening where the computer would freeze and the fan would come on at full speed and be very loud. It also started happening when I turn off the computer for a while and turn it back on again. It would not start up and the fan would just kick in. The only way I could get it going was to manually turn the machine on and off until it would eventually turn on properly. Sometimes I would have to do this 4 or 5 times.
Then today the computer just turned itself off automatically. No warning, nothing, just click and off like when you have a power cut, but there was no power cut. So I ran a quick hardware test from the OS installation disk and it said that it detected 2 faulty RAM sticks at startup. I was worried it might be a logic board problem but that has come back on the test saying it is okay.
Would having faulty RAM cause the above to happen? And how reliable is the hardware test that comes with the Apple OS installation disk? I am praying it is just RAM and nothing more expensive. I am gonna clean out the fan today, and dust things down a little bit just in case it is a bit of dirt or something, but I would be interested in other people's opinions.
My family just recently upgraded from an old PC to this 27" iMac, during the early part of the summer. While using it over the last little while, I would notice a noise that sounded like a harddrive spinning or possibly some sort of a fan noise. The best way to describe it would probably be as digital noise. It's not incredibly loud, but it's a decent volume, and can get quite annoying. It has a little bit of a squeak to it.
Over the last little while, it's become more constant. When the computer is in use, it'll usually occur quite often. It's quite annoying and obtrusive when I'm watching videos and I'd like to know what it could be.I think our computer is still under warranty, so I'm hoping to find out if it is something wrong, so I can get it replaced.
I've also been wondering if it's a fan, or a regular noise. However, it's so constant that I'm starting to wonder. The other night, I was watching a video and it seemed like it was coming on every 30 seconds for a long span of time. We don't run any memory heavy programs on this computer. If anything, we're just using Firefox, iTunes and/or Messenger. Sometimes Office. There's little to nothing stored on this computer, as it's brand new, so most of its memory is free.
This morning the hard drive on my G5 sounded like it was at 8000 rpm's and there was a message on my screen to shut down the computer using the power button. I did this. Now anytime I try to power back up, I get the white screen with the apple and the "booting" icon, which then goes to a blue screen with the same icon, which then is just the blue screen with my mouse icon floating around. Also, on the random occasion, after booting to the blue screen it takes me to a DOS looking screen that asks for my login and password, of which I have neither.

I have a DP 2.7 G5 Tower and lately I come into my office to find it with dark screens (dual monitor setup), and I am unable to in any way control it by the mouse or keyboard. I imagine it's "hung?" The fans are on full blast and it sounds like it's planning to take off at any moment. I've awakened in the middle of the night by the sound of it and it's in that same state. What to do? I restart it at the power button. I then have to run Disk Utility to verify all the disks and RAID setups.
Anyway, I read about the coolant leaks issues. I started running a temperature monitoring program for the past few months, and its been doing about the same type of pattern since I started monitoring it. Doesn't appear to be unusual. Everything appears to be working fairly well, except for this issue. System is OS X.4.11, and checks out fine with Disk Utility. So far the hard reboots haven't done any damage to my disks, but it worries me greatly. Also the "liquid cooled" aspect worries me greatly.

I was out of town so this description was second hand but the computer has been running a little weird for a while. When I have too many apps open or on a website that has a lot going on...the computer starts revving up until I quit out of everything and let it slow down. I guess while I was gone, this happened but nobody quit out the apps and it eventually turned the screen black. When I tried restarting it sounds like the computer is working but the screen is black so I can't see if it is booting up or not. I took the monitor into the apple store yesterday and it started up right away for them. It's a cinema 23" I think.
