People iMacs are turning off. This has been happening to mine for months.Â
I have 24GB of RAM. I expanded it with memory from Crucial's website when I first got it. This problem seems to be getting worse. I come back to my computer to find that it has restarted itself. Â
The iMac is running OS X 10.8.5. The model identifier is iMac13,2.Â

iMac, OS X Mountain Lion (10.8.5), 24GB RAM 2.9 GHz i5

It has just started to turn it self off then re start up on its own about 1 or 2 minutes later and then some times I just can't get it to turn back on again. I think it could be the psu?

I have an iMac G3 which I am VNC'ing in. Its never going to be turned off, and I am never going to look at the screen, so how do I turn it off? I Want to save the CRT, and its not needed. I Know there's a way to actually turn off my MBP's Screen.

I'am holding off till tuesday to wait for WWDC to see if there is any news on Imacs. If there isn't I assume that it will be a quiet update, should i wait for the quiet update or buy one after the conference blows over.
The noise starts immediately after hitting the start button and continues as long as the computer is running.It sounds similar to fan blades rubbing on something. This started while I was using the computer.

I have a 24" 2007 iMac, the first aluminum ones, 4Gb of Ram and a recently upgraded HD to 1Tb (from a 320Gb failed drive). Recently, I have noticed that under some active usage, such as playing World of Warcraft or Excel, the screen will start to turn completely off for 10 seconds, and then back on for 10 seconds. It will continue to do this for about 3 hours, turning on and off every few seconds or 15 seconds. It will mostly turn completely dark but would also sometimes flicker. The curious thing, is that if I continue to keep playing, the screen would cease doing this after about 3 hours and then be completely normal and fine, but the next night.
The symptoms would repeat itself, and would consistently go away after active usage (3 hours or so). Imagine this, as if the iMac itself needs to be "warmed up" for 3 hours before normal usage. It would also appear that if I hit the machine (or tap it), this may sometimes bring a dark screen back to life for a few seconds. I plan to bring it to support, but I just want to get some ideas from you guys as to what this can possibly be.
Some of my guesses:
1) It cannot be software as physically hitting it or my dog barking would affect the rate and speed of the random turn Ons and Offs.
2) It could be a loose connector from my recent transportation of it while upgrading my HD, but then why would it become normal after 3 hours of usage?
3) Maybe something to do with RAM or video RAM? It is faulty, and thus only prolong heavy usage would "run it in" for the session? After not using it for a while, it goes back to its failed state?
I tried googling this right after I bought my new iMac (on black friday). There is a little switch at the bottom of the magic mouse for turning it on/off. My question is every time I turn off my computer should I switch the button to the off position? Is there any benefit from leaving it on/off?

Windows user here that just ordered a 27" QuadCore iMac. Usually on my PC at home, whenever i'm not using it I turn off the monitor but leave the computer itself running most of the time (I run a lot of torrents, VNC, etc). Is there a way to turn off only the display and keep the computer running like I normally would on the PC?
View 7 Replies View RelatedI have a first gen iMac 24 Intel with a dead logic board. However everything works in it. The screen, power supply, isite, speakers. appear to work fine. I got a MacBook Pro to replace it and I wanted to know if there is a way to turn the old iMac into something that is more like the Apple 24� display, even if I need to do electronics work in it.
I am in IT and have access to a lot of dead stuff I can scavenge for parts. I am also an electronic technician, so I should be able to do this. I just don�t know what I need to do.
Hunting down info on this topic has come with that there are controller issues. If I can pull a controller out of another dead LCD display that I happen to have, I can see it working. I can even see the possibility of adding the electronics from a USB hub to pipe USB functions over a DVI cable. And get the iSite and speakers working.
I'm looking to turn my new macbook pro into an external mimic monitor for my new imac. ...like, so that I can move my mouse from the imac screen to the pro's screen. How do I do it? Is it possible to do it wireless?
View 13 Replies View RelatedI've never owned an imac since I don't care for the AIO concept due to the fact that when your computer becomes obsolete, you lose the monitor as well, without any good reason. I really need a new computer, and as usual I'm thinking about the mini. The problem is that they are really slow and I need the hardware of the imac. I figured that buying an AIO, isn't that bad if you can still use the monitor even when the computer's hardware is obsolete. I've summed it up to a couple of questions:
1. Can you use the imac as a monitor for another computer without turning the enitre hardware on? Perhaps you can easily mod it, so that the monitor is the only thing working.
2. As a follow-up question, if something goes wrong with the imac, that isn't related to the monitor directly (i.e cpu, ram, hdd, etc..), could you still use it as a monitor for another computer?
If the answers to those questions are positive, I'll probably get a 27" imac.
I've been using Pc's for the past 30 odd years so am totally new to Mac. I'm doing my best to adapt to this new different OS and so far have found some things more user friendly but others ? I've more or less given up on those as Mac doesn't seem to do those things. These are probably Windows based and I'm assuming Mac has its own alternatives that I haven't discovered yet. Anyway, my immediate problem is this goddamned frustrating situation when I try to re-activate the comp' after waking it from 'sleep'. Sometimes its fine but others, it comes back on but freezes and the only option I have is to turn it off at the switch and do a re-boot!
