Mac keeps FREEZING and screen goes BLACK!?!

My computer freezes up and eventually the screen goes black withe the rainbow waiting mouse. So I restart it manually by pressing the button, and turn it back on again. I login, the old programs come back on. I try to click something. The screen freezes andgoes black again with the rainbow waiting mouse.
This happens everytime.
Repeat. Repeat. Repeat.
-I left it off all night and tried it again in the morning. Didn't work.
-I think it started when I plugged my iPhone 4 in the usb.
-itunes wants to update but I can't do it.
-between restarts, I noticed that there was a software update sign, but my computer kept freezing and turning off.

its a MACBOOK PRO

Satellite L405D-11V - Freezes and screen goes black when watching video

Ok, so I have the Toshiba Satellite L405D-11V, I have had a fault, basically, the computer would freeze at any time and the screen would go black, with the fan and lights still going, this could be on start-up, or a few hours into using the laptop, so I decided to ring up Toshiba's tech support and they arranged for my laptop to be collected and sent off for repairs.
I was able to track the repairs online through the tracking service, and was able to see what they were doing to my laptop, it said that they ordered a part, it was in progress and the repairs were finished.
However, I got the laptop back today, I turn it on, everything is fine, I start using the laptop everything is fine, then I decide to watch a video on youtube, and it freezes again, so, I power off holding down the power button, hoping it was just a one off, I turn it back on, and load up the video again, it freezes and the screen goes black again, after working out that when ever I watch a video or play a game, it causes the computer to crash and freeze like before the repairs. So there is still a fault, but im not sure what to do
Its still under warranty, I purchased the laptop from Comet, but I dont really want to send the laptop off for repairs again and to find it will come back with the same fault, is it worth sending it off again, perhaps seeing if comet will replace the laptop as its still under a year of buying the laptop, or is it just gonna be worth saving all the hassle and buying a new laptop? If this fault has happened to anyone else, I could sure use some help, and if someone could shed a little light as to what might be wrong?
Thanks

Hi buddy,
Did you change something on configuration after you got your notebook back from repair? Did you update a driver or something else?
What operating system you are using on your Satellite L405D?
To be honest its really hard to say why it happens because the technicians test everything to check if your notebook runs properly.
In my opinion you should try updating the display driver. Maybe its causing the issue
If not I would recommend installing Windows from Toshiba recovery disk to restore factory settings. These settings are pretested by Toshiba and should work.
If you still have the problem you must contact the technicians again. I mean you could track the repair online and according your posting everything worked well during repair so in my opinion it shouldnt be a problem to contact the guys exactly.
Explain your problem very detailed. I think everything can be clarified then. :)

Intel Mac freezing and screen going black

Hi,
Has this been happening to anyone else? My Intel Mac was freezing up a lot a month or so ago. It mostly happened while I was using Motion 2, but also while using Firefox or when it was asleep.
I did a clean install of Tiger and only updated to 10.4.9 (I thought the newest OS update may have caused the problem.)
It has froze a few times since then, but not as often. Just now I was working in Photoshop and the Finder and the screen just went black like it was asleep, but would not wake up. I finally did a hard reboot using the power button.
(When it was freezing up about a month ago, usually the screen would freeze up or I would get the spinning beach ball of death.)
After I rebooted the error report alert came up and here is the report:
panic(cpu 2 caller 0x00191931): pmapflushtlbs() timeout pmap=0x4b1700 cpustosignal=0x2

Any advice or suggestions? Call Apple Care again?
Thanks!

This is how I would approach it:
_Initial troubleshooting_ (you've probably done this already – sometimes it is easier to fix the problem without finding the root cause)
- +Disk Utility+. Boot from the Mac OS® X install CD. After the language selection screen, when the main screen comes up, wait until the menu bar at the top of the screen populates. Then select Disk Utility from the menu. More information is available:
http://docs.info.apple.com/article.html?artnum=301170
http://docs.info.apple.com/article.html?artnum=106214
- Reset NVRAM/PRAM. See:
http://docs.info.apple.com/article.html?artnum=2238
_Further troubleshooting_: the following may assist in isolating the cause of the kernel panic.
+If the problem still occurs primarily in only one program+ (such as Motion 2), then uninstall that program.
+If it seems the problem is random now+: did you install any new hardware recently? If yes, then remove that hardware and see if the problem still occurs.
+In System Preferences+, under Sharing, make sure that file sharing, Windows sharing, web sharing, remote login, etc. are turned off.
+Hardware diagnostics+: on some Macs, you can run an Apple® Hardware Test by holding down the '''d''' button while booting the computer from the Mac® OS X install CD. You may see a blue screen with a small icon in the middle. After about 2 minutes, instructions will appear; please follow the on-screen instructions for running an "extended" test. If the Apple Hardware Test finds a problem, then take the computer to the Genius Bar® at the local Apple store, or call AppleCare® again; maybe with the 12GB of RAM you have, some of might be bad. Also, when you visit the Genius Bar or call Apple Care, have a printout of the above (your post) available; additionally, you may wish to write down the kernel panic message again so the support staff or you yourself can compare the 2 error screens and see how they are similar or different. Anyway I strongly suspect a hardware problem but it could be almost anything.
+Open up your favorite antivirus program+ and scan the entire hard drive just to make sure, if you have not already done so.
If all else fails and you need to reformat (you should probably go to the Apple Store to rule out any hardware problems before doing this), then choose the "zero all data" option under "security options" in the Disk Utility program. This erases the entire disk, not just the directory structure.
In conclusion I think you are right about calling AppleCare again but I hope these steps are useful (if they are not a recapitulation of what you already know).

My mac keeps freezing and someone suggested turning off airport. Have no idea what this is or how to do it. Any help gratefully received.

Have anew netgear router and now mac keeps freezing and iphone wont download e mails. Help

Hello TracyOShea,
It sounds like your Mac is becoming unresponsive for no apparent reason. I recommend starting by resetting your computers SMC:
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/ht3964
Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
Then perform a Safe Boot, and then restart the computer again and retest the issue:
OS X: What is Safe Boot, Safe Mode?
http://support.apple.com/kb/ht1564
To start up into Safe Mode (to Safe Boot), follow these steps.
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key.
The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple logo and the progress indicator (looks like a spinning gear).
After the logo appears, you should see a progress bar during startup. This indicates that your computer is performing a directory check as part of Safe Mode.
To leave Safe Mode, restart your computer without holding any keys during startup.
Thank you for using Apple Support Communities.
All the very best,
Sterling

My MacBook freezes & the screen goes black!

My MacBook keeps freezing up and the screen goes black. It happens a lot when the computer "goes to sleep"--it will just go unresponsive. It's weird because even though the screen blacks out, I can still sort of see what is on the screen! The computer is always still running, it doesn't shut off. I have no idea what this means! Can anyone help me??

If this is a new MBP, then make an appointment at an Apple store genius bar and have them fix it for you under the warranty provisions.
Ciao.

My I Mac keeps freezing, and shutting down apps.

Hello,
I have an I Mac, it keeps freezing, and when I open my applications it will shut them completley. (i.e Chrome keeps shutting down by itself, Skype dissapeared and Gimp is just a question (?) mark now )
I tried restarting the computer on safe mode, and I tried restarting it a couple times, after leaving it off for a couple of minutes. My computer has never been this slow and temperamental since I got it in 07. PLEASE HELP.
Is there a way to clean up my disk, or check erros, or just figure out what is causing my computer to act so slow?
I will gladly appreciate any suggestions from the pros!

PLEASE HELP ......

Open ibook past 45 degree angle and screen goes black

My iBook's screen goes black once it gets opened past about the 45 degree angle. I purchased it in July 2001...is this the life expectancy of an iBook? It has been repaired many times and still has OS 9 (bc the CD drive doesn't work so I can't update it) so is it just old and junked?! Thankfully I have a eMac now, but it's nice to have my laptop available also.
Thanks for any and all help in this matter!
Kelly

Hi, Kelly. Welcome to Apple Discussions.
DT & T Computer Services will repair the inverter cable for you for $125 plus shipping. They also do free diagnostics, so if that isn't what's wrong, they can tell you what is and how much it will cost to fix it.
Good luck.

My mac keeps freezing and every time I turn it on, the screen flashes purple for a second before it starts up.

Can anyone tell me why this keeps happening and how I can stop my mac from suddenly freezing? It's a 15 inch retina display.

Try a reset:
1. Hold the Sleep and Home button down (together) for about 10 seconds
2. Until you see the Apple logo (very important)

Why does my Mac keep freezing and applications not responding?!?

Hello everyone, I have a mid 2009 MacBook Pro, 500gb HD, 4gb ram. The problem is that it keeps freezing. I am writing this on my iPhone because my laptop would probably just freeze up if I even attempted to open an application. The problem is that my laptop won't stop freezing up. As soon as I have any application open, it will stop being responsive, give me the beach ball spinning wheel thing, and I'll use command-option-escape to open the force quit menu (because at this point the mouse usually can me moved around the screen but just makes the system get worse) to force quit what ever applications I have open. Then finder will stop responding, and then nothing will work until I do a forced shut down (hold the power button down) and turn it back on again, where the same thing happens within a minute. I tried repairing permissions and doing a P RAM reset, but have had no success with either. Please help, this is ridiculous, I can barely use my laptop and I need it for school. Thanks,
-Dylan

New iMac Can't See HD and screen goes black then grey then black..etc.

Hi I've got a new 20" Alu iMac and it was working fine for the past 3 weeks. All of a sudden this morning starting it up the screen went completely grey then after a while the apple logo came on (I thought it was eventually starting) then it went completely black (this is normal just before the progress bar jumps in) but this time it didn't! , the screen just went to grey again and the cycle started again and kept going on like this for an hour. I tried starting up from the disk the iMac came with but under disk repair i could not see the HD and trying to reformat the HD it was just named 'Media'. When selecting the drive to format an error came up saying explain it could not be formatted in the selected format!!! There is only 2 options to format the drive.. Mac OS Standard and Unix.. Both did not work. Any suggestions? Thanks

Contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine. It's not clear if that applies under the 90-day warranty.

Mac keeps freezing and crashing

Hi,
I'm on a late 2009 iMac (3.06 Intel Core 2 Duo, 12 GB 1067 DDR3, 1TB HD) with Yosemite. I installed Yosemite a few days ago. Previously I ran Mountain Lion.
While on Mountain Lion the mac suddenly started freezing and crashing. I could still move the cursor, and most of the time my sound kept working (although the screen had frozen I could keep on calling via Skype - music and videos mostly stopped working after a minute or so), but I had to force turn off the mac. Upon rebooting most of the time I couldn't get past the start-up screen with the grey progress bar and Apple logo. The problem persists with Yosemite. There isn't any specific program which seems to cause it - I've had crashes running many different things. It doesn't seem to be a kernel panic: I've had only one instance where the grey letters would show up. Otherwise it just crashes.
I've tried many things to fix it already:
- running DiskWarrior and removing corrupted files
- removing dubious third party extensions
- removing unnecessary login items/Launch Daemons/Launch Agents (after running EtreCheck)
- I ran AHT twice (nothing came up) and Rember once (idem)
- ran recovery mode to verify the disk (nothing came up)
- ran Safe Boot for a while (no crashes), which causes me to believe it's a software-related problem.
I reinstalled Yosemite yesterday. It will only boot into safe mode since. While booting normally I can't get past the white screen.
About three months ago a faulty HD was replaced and RAM (8 GB) was added, both done in an Apple store. I've no reason yet to believe it's hardware-related because every test comes up clean, but I'm obviously not sure.
I don't know what to do next other than bringing it to the store. Any help would be much appreciated. Because I'm in safe mode my EtreCheck report differs from the normal report - if it's helpful to post it anyway, I will.
Thanks!

Macbook pro Keyboard and screen going black, not responding

I have a mac book pro, 15 '', bought april 2012, since two days ago, while i am using it the screen and keyboard are going black, and they don't respond, but i can still listen to music. It only respond if I force the shut down. Help!

Check out KB Articles http://support.apple.com/kb/HT1411 Apple Portables: Resetting the System Management Controller (SMC) and http://support.apple.com/kb/HT1379 Resetting your Mac's PRAM and NVRAM.
If you have AppleCare, call them. Let them deal w/it.

Clicking noise and screen going black

Every so often my iPad makes a noise like it is taking a picture and goes black. After hitting the home button it it back to the slide to unlock screen. I have never dropped my pad so I'm not sure what is going on. I have an iPad 2 that was new in May. Any advice would be helpful.
Thanks!

If you have the time, try the Apple Hardware Test (AHT).
1 Disconnect all external devices from your iMac except the keyboard and mouse.
If you have an Ethernet cable connected, disconnect it.
2 Insert the Mac OS X Install Disc 1 that came with your iMac.
3 Restart your iMac and hold down the D key as your iMac starts up.
4 When the Apple Hardware Test chooser screen appears, select the language
appropriate for your location.
5 Press the Return key or click the right arrow button.
6 When the Apple Hardware Test main screen appears (after about 45 seconds), follow
the onscreen instructions.
7 Apple Hardware Test displays an error code if it detects a problem. Make a note of the
error code before pursuing support options. If Apple Hardware Test doesn’t detect a
hardware failure, the problem may be with your software.
For more information about, see the Apple Hardware Test Read Me file on the

IMAC 20" intel - System freezes and screen goes blue - why??

this just started yesterday - I did not add any programs or update any software recently. I have since added Norton and scanned for viruses.
PROBLEM: my system freezes and the screen goes blue. It does not "wake" back up right away and after it goes blue a few times, it stays blue and I have to hard boot. If I leave the system off for about an hour, I'll get a few hours out of it before this happens.
DIAG: As stated above, I checked for viruses. I also ran all available diagnostics, and am fresh out of new ideas. Since I can't open my iMac without voiding the warrantee, I can't check for any possible burst or bulging capacitors. I disconnected all perperials and still have the same issue.
HYPOTHESIS: I am heavily leaning toward a hardware problem, but before I take the trip to the Apple store, I wanted to reach out to the forum to see if anyone else has had this problem?
This is an early 2006 Intel based 20" iMac that I have been running (24x7) since late August 2006. I never had an issue with my first iMac (pre-Intel).
HELP!!!

Dreaded 90 degree and screen goes black

I have been putting up with my ibook screen going dim whenever you open the screen to 90 degrees for about five months. However, it is now starting to become really annoying because I have to switch the computer off, close the screen and reboot it in order to regain the picture. Does anybody in the UK know anywhere where I can send it to be fixed or indeed how much it costs roughly if I have to send it back to Apple? I believe it is simply a problem of damaged cables that need replacing.
I am starting law school soon and about to invest in a new imac but it would be useful to keep my trusty old ibook ticking over to use in the library etc (it's lasted me 4 years through my degree!). Any advice on this matter very gratefully received!!
Thanks

Here in the U.S. there is a repair shop in Vermont who used to do it for $79.90.
If you take it to Apple, the official Apple Authorized repair is to replace the entire display (at a cost of hundreds of dollars).
You may want to check out this long-standing thread for some idea of what you are up against:
http://discussions.apple.com/thread.jspa?threadID=207731&tstart=0
And even add to it, maybe?
