Intel Mac :: Constantly Losing WiFi Randomly While Working
Apr 19, 2012I am running an imac 24-inch Mid 2007 on 10.7.3. Always do the updates and everything seems ok. I have been having problems with connecting, reconnecting after sleep and just losing my connection in the middle of being on wifi. I have replaced my wireless router, I have deleted all previous wifi networks. I have also renewed my dhcp license. Nothing works. To reconnect, I have to continuously go to network preferences, assist me, diagnostics, then continue with the assist me and choose my network and it then reconnects. This is not just waking from sleep. Sometimes just randomly while working on the computer. I have read some things about equipment plugged in and I have an ATT micro cell plugged into 1 ethernet jack in my wireless router/modem, I also have a bluetooth mouse, a printer plugged in USB and a Lacie HD using Time machine.

IMac (Intel) :: Randomly Drops WiFi Connection
Jun 25, 2014I have full Wifi signal and I'm using multiple device on my Wifi which are all stable except the iMAC. We had a power failure a couple of weeks ago and since then the iMac just won't stay on the network. I have to turn wifi of and then back on to get it to join and that mitt lat 10 minutes.

Dec 5, 2010At least, it seemingly randomly turns off. I can be surfing the web or whatever like normal, but then after a period of time the monitor goes black. I can see that the computer hasn't shut off, but it's as though the computer is on its lowest brightness setting. It can be temporarily fixed some times if I lower the brightness all the way via F1, then put it back up, but if it goes up more than 3 or 4 boxes it goes black again.
It also goes black if I were to move the monitor any time during this whole thing. I've heard things like an inverter cable and board, but I have no idea what's going to fix this. This is my only computer, I use it for all my school work, if it breaks permanently I'm screwed.
Software :: Mac Freezes Randomly And Screen Turns Blue
Nov 9, 2009My Mac will freeze at random moments (not while running any particular app or program) and go to a blue screen, after a few seconds it clears up by itself. Sometimes it will happen several times in a row, sometimes 10 - 15 minutes in between.

May 19, 2012This is a strange issue I have had with my Macbook Pro for a while now. Whenever I am in a situation where I am only using my computer for say, listening to music purposes, I like to turn the brightness all the way down. Whenever I turn the brightness all the way down, however, after a few minutes it will go back up 1 pip of brightness on its own. Once I come into contact with the trackpad, however, it goes back down. Then it will go back up 1 pip on it's own again, and go back down when I touch the trackpad. It continues to do this and it's quite annoying.

May 26, 2012My brand new imac randomly disconnects from the internet. We have a BT hub - wifi. I have googled this issue and see that it is relatively common and it is incredibly frustrating. It is fairly simple to reconnect each time but it is driving me mad having to. It generally happens when the computer is asleep but sometimes in the middle of doing something.

Intel Mac :: Screen Just Turns Off?
May 23, 2012I got home to find my mac was unresponsive. I thought it had fallen to sleep so i kept pressing keys on the keyboard and clicking the mouse. Nothing happened, I tried everything. So I turned it off by holding down the power button and turned it back on. But then 10 mins later while using it, the screen just instantly turned off! The iMac was still running, it even had the music still playing in the background from iTunes, but again it was unresponsive to my commands. After 1 minute the music turned into an awful static cry for help. So i turned it off. Here i am again on the Mac after turning it back on, but i'm scared it could just go again any second.Â

Intel Mac :: I3 Mid 2010 21,5 Turns On Periodically
Apr 18, 2012I read a lot about that issue but I found replies about imacs that wont turn on. But my Imac after the problem, turned on one time.
My issue is that my imac was working like a charm. The day before yesterday, at night, i had an automatic update of firefox and after i switched it off normally.
The day after, at morning, I tried to turn it on but it was behaving like it was not attached to the electricity.
I started to read and I found all that solutions so I did the following:
1. Tried other cables (for power supply)
2. Tried other plugs (in different rooms)
3. Put out the ram sticks and cleaned with a blow dryer the sticks and the space inside the imac so the dust goes out.
4. Tried the reset of SMC with no success as it could not be turned onÂ
I tried everything and after I leaved the mac alone, (3-4 hours) and after i just clicked the button and it was on. I left it all night long switched on so that i save my data and I found it on, this morning.Â
So this morning I did everything to reset the SMC. I put it in sleep mode, restart it, shut it down, put out the cable for 15 sec, put it back, wait 5 sec, but it wont turn on again. I know that there are a lot of responses for the same issue, but I didn't find one that the imac turns on periodically.

May 22, 2012My AppleCare just ran out a little while ago and now my iMac is starting to shut off. Usually, in iMovie and iPhoto but today if I plug a USB Memory stick in I lose connection to my Bluetooth devices. Yesterday, everytime I tried to open a .pdf file on the USB drive the computer would shut off. I am fairly certain it is the logic board? I wish this had happen a couple months ago then it would have still been covered.

Intel Mac :: 27" Turns Off As If It Short-circuits?
Feb 9, 2012I've only noticed this happening when I'm using Photoshop CS5... I have an iMac 27" with: Â
Intel Core i5
2.8 GHz
16GB MemoryÂ
(Mod identifier: iMac11,3)Â
WHEN I USE PHOTOSHOP, and I use the free transform tool to enlarge (only when I enlarge) an image, the computer turns off completely, instantly without any warning. Just straight to 'OFF' mode. I have to start it again with the power button. No reports of unusual behaviour come up on the screen, it just shuts off as if there has been a power cut. Nothing else shuts off from the power supply, just the iMac so I know the problem is definitely internal (within the iMac).

Intel Mac :: 24" Always Turns Off At Grey Screen In Less Than A Minute, Can't Load Snow Leopard To New HDD
May 25, 2012I put a new hard drive into my iMac 24". I could not install OS X because every time I turned the machine on it would shut down in less than a minute at the grey screen and Apple logo - whether the disk was in the slot or not. I finally was able to install Snow Leopard via firewire from a Macbook Pro. It runs fine - but I can only access the iMac Snow Leopard installation from the Macbook Pro. When I turn on the iMac, it still shuts down every time. The new drive was formatted with the Disk Utility as an external drive - since I couldn't get to it while it was in the iMac. My Snow Leopard disk was a full version, not an upgrade.

Intel Mac :: Sound Randomly Goes On And Off?
Mar 1, 2012I have a 2006 IMac that works perfectly except for one thing. One day last year out of the blue the sound stopped working and I would get the 'not allowed' circle when I tried to adjust the volume. the problem persisted for a week or so, then the sound just came back on. Everything was fine untill a month ago when the same thing happened. I did some research and tried the toothpick trick and everything related but nothing worked, then the next morning the sound was on. Over the next few weeks the sound would go on and off randomly for no apparent reason. It has now been off for two solid weeks and I don't know what to do. Is it possibly a loose connection inside the computer that just needs to be plugged in?

Jun 23, 2014I purchased a new late 2013 27 inch iMac 3.4Ghz i5. The only thing I did after pulling it out of the box was restore Time Machine from my previous iMac. On startup the machine boots as expected, but gets interrupted by the screen turning a dark blue, and the apple logo turning bright red, for about a second or so, then boots as normal, and opens Mavericks. I've spoken to Applecare - they suggested I re-install Mavericks, which I did. The problem is still there. I've done a hardware diagnostics test - no problems. Though I wonder if it could be a faulty graphics card? As far as I'm aware there are no other issues with the iMac. The machine is under warranty but would love to solve this if possible.
View 1 Replies View RelatedIntel Mac :: Freezes And Crashes Randomly
Feb 3, 2012My iMac randomly freezes and crashes on me. Most of the freezes occur when scrolling with my trackpad on websites with Google Chrome. I get the pinwheel and have to use the power button to turn off and on the iMac. I haven't noticed any particular connection to Flash websites or video related sites. It just seems kind of random. I've also been careful to have absolutely nothing else running and it still does not prevent it. Â
Also, from time to time the iMac will crash and go to a solid color screen. Either Blue-Gray, White or Black. It seems to be random colors. When this happens, I have to use the power button to cycle it off and back on again.Â
Some info about my iMac: Model Identifier: iMac7,1 Processor Name: Intel Core 2 Duo Processor Speed: 2 GHz Mac OSX 10.6.8Â
What could be causing this or how can I diagnose the problem? I can give more info if needed.
