A series of random freeze
Suddenly, a series of random freeze :
1/ Dialing a number, any number, receives a message : "call impossible"
Solution : had to reboot
2/ After a call, my correspondent ended conversation, and my screen being black, I had to push button to light it back. Problem is I couldn't end the call on my part.
Solution : had to go in contacts, dial another call, and put an end to it, to finally unblock the screen.
Did you add a new program just before it began. The need to trouble shoot the phone asw you would your computer. Try restoring from and older backup.

IPod randomly freezes when playing tunes
My Ipod 30gb randomly freezes during a song. Sometimes it freezes for a few seconds and sometimes it can freeze for a couple of minutes. It then just carries on playing.
It is not always the same song and can include songs purchased from Itunes as well as CD's downloaded - i.e. it is totally random.
All of the songs play perfectly on Itunes. I have only about half filled the iPid so am not really in the market to upgrade.
It has only started doing this about for the last two months.
Could some dust or something have got into the IPod or could it be a battery issue ( although I try to keep it at full ).
I have downloaded the lastest updates of software ( 1.3 ) and always click on the update software buttom when am synching. I have also done a restore and all the other troubleshooting bits to no avail...
Help....Hi,
Well my friend got me an ipod 20gb 4th gen from ebay.

Listen to the hdd it should just be a smooth wirr if it wirs up and down like mine did (e.g. spin up and then off) its a HDD issues and u need to fix it soon. if under warranty take it to apple or pay to fix it. i have no idea how to solve it but this might help. try this..put it into diagnostic mode by resetting it, and then holding select and the back arrow select all test and it will tell you if has issues.
diognosis test and what they mean
A. 5 IN 1: This runs the following 5 tests at once (J through N as listed below): LCM, SDRAM, RTC, FLASH/CHECKSUM, and FIREWIRE/FW ID. If you have a 3G iPod, at the end of the test, your buttons will now play a series of sound effects.YOU MUST PRESS ALL BUTTONS WHOTH IN % SECS SO IT CAN CHECK THEM
B. RESET: Can your iPod reset? Run this test and find out.
C. KEY: After you start this test, you need to press all the buttons on your iPod within 5 seconds. If you don't do it fast enough, it will fail.
D. AUDIO: Plug in headphones, but don't expect an electronic rendition of Pink Floyd's Dark Side of the Moon. This test checks the audio subsystem. You will see a message that says "0X00000000 DONE" if your iPod passed the test.
E. REMOTE:
This will test your iPod's Remote if you have one. Plug it in or the test result will be "RMT FAIL".
F.FIREWARE: Checks your iPod's FireWire port. A successful completion of the test will return "FW PASS".
G. SLEEP: Will put your iPod to sleep. You will need to reset your iPod to wake it back up.
H. A 2 D: Tests the iPod's power. Your results should look something like this: "3.7V 0X000000E2 CHG OK FW 1 BAT 1". The results will be different depending if your iPod is plugged into your computer, a wall outlet or is just running off battery power.
I. OTPO CNT: Tests your scroll wheel. Results are returned in hexadecimal.
J. LCM: The LCM is your iPod's screen. Keep pressing the "Select" button to toggle through several pattern tests.
K. RTC: Tests the iPod's built-in "Real Time Clock".
L. SDRAM: The RAM memory test. Hopefully it will tell you "PASS"
M. FLASH: Your iPod has built-in Flash memory that stores firmware information. This test will tell you what Firmware version you have installed.
N. OTPO or
Wheel A2D: Tests the A2D (analog to digital) input of your iPod's scroll, touch or click-wheel. You need to reset your iPod to exit this test.
O. HDD SCAN: Scans your iPod's hard drive. This is a great way to see if you have a healthy iPod. This test will take a few minutes so be patient.
P. RUN IN: Tests your iPod's chip sets continuously.
Try all test and try another hard rest and resotre even though you have if game andd no how open ipod dissconnect battery to hdd lead and leavee for 20 mins or discharge ipod and charge then see if it fixes it or clean ipod out being carfull not to break or touch anything
hope this helps.... -
My macbook pro late 2008 randomly freeze
Hi I recently upgrade my macbook pro Late 2008 by adding a 250 go Crucial SSD drive in the main harddrive spot. I also put a 1 To HDD in the place of the super drive.
Since then, my macbook randomly freeze. I can't see any link to any specific usage. It just happen for no reasons. I had to reboot by holding the power button.
Thanks for your help!

Some or all of the following may be necessary - try in this order:
1. Try resetting your PRAM/NVRAM ( http://support.apple.com/kb/HT1379?viewlocale=en_US ). If everything isn't fixed, then continue to follow the steps here including resetting your SMC ( http://support.apple.com/kb/HT1411 ) if necessary.
2. Use Font Book to eliminate all bad and duplicate fonts.
3. Reinstall (or install for the first time) the .6.1 and .6.2 updates by downloading and installing the combo updater ( http://support.apple.com/kb/DL959 ).
4. Reinstall 10.6 using your Snow Leopard install DVD by installing Snow over Snow using the upgrade method. Test your system after returning to 10.6. If is good there, then you may not want to re-install the.6.1 & .6.2 updates - if you do, then use the combo updater again ( http://support.apple.com/kb/DL959 ).
Still no joy, take it to an Apple Store and ask staff there for assistance. -
Windows7, can't install, random freezes.
Hey!
Just got a new computer, It worked fine in the beginning, no trouble installing Windows 7 Ultimate (32bit). After ~1 day random freezes started... I tried reformatting and reinstalling Windows 7 but the problem came back.
I tried reinstalling one more time but now I can't even install W7. It freezes at random points all the time, sometimes before the installation begins, sometimes when I chose which hdd to use, sometimes while expanding files.
Now I use Windows XP and it runs fine without any freezes but I would like to use W7...
I've tried a different PSU, GFX, DVD-reader and HDDs without any luck. 1 DDR3 in DIMM1 doesn't help, tried them both single channel.
-::- resetting CMOS and I've updated to BIOS 1.4, the problem is still there... but it works like a charm in XP.
-::- 3 different Windows 7-versions (2x32bit 1x64bit) and also Vista 64bit doesn't work (haven't tried 32bit, but I'm sure it won't work)
-::- installing Windows 7 via USB-hdd and it doesn't boot (on my other computer it does, so it's bootable and I'm not doing it wrong)
-::- change from IDE to AHCI setting in BIOS, GreenPower Phase Control(From Auto to Disabled), Intel Turbo Boost Disabled
-::- with only PS2 Keyboard plugged in, no other device, I have nothing in the PCI-slots and not the MSi THX Quantum Wave blablabla connected...
-::- different SATA ports both blue and black, tried IDE DVD-reader.
-::- change DRAM voltage to alot of different values, max 1,65V min 1,4V
-::- load fail safe bios settings
NOTHING OF THIS WORKS... please help me:-)

Any suggestions;D?Quote from: Jack on 16-December-10, 00:56:52
The symptoms don't make much sense, to be honest. Strange scenario you have there. If there was a hardware problem, it would show itself in XP as well. On the other hand: When the system freezes on the Windows 7 Setup level for no apparant reason, it is hard to even blame driver problems of any sort.
Run Memtest86+ to be sure that there are no obvious memory problems behind this.
Also, disable ALL power saving features in BIOS Setup (C-States, EIST, C1E Support, Greenpower/APS features of the board) and also Spread Spectrum.
Have you tried running any more intense stress test applications under XP (Prime95, 3D Mark, Furmark) to check if you can trigger freezes by stressing the components somewhat more?
Do you have any other components to do some swap-out tests (e.g. different memory modules, PSU, video card, CPU)?
I've already ran Memtest and it showed nothing, forgot to write that above:p
Gonna try all powersaving features disabled now and if that doesn't work I'll do some stress tests with XP.
I have PSU, video card, and some hdds. No memory or CPU with same socket...
BTW:I t started Expanding Windows files and its at 26% atm:D:D:D:D:D::D:D -
Sound Blaster X-Fi Xtreme Gamer Fatal1ty - Computer randomly freezes accompanied by a single be
I just bought my X-Fi Xtreme Gamer Fatalty Pro Series and my computer randomly freezes for up to 0 seconds and I hear a single beep from my internal computer speaker after which my system goes back to normal for about 5 to 0 minutes and then it repeats the same process. I have upgraded all my drivers for my motherboard, including flashing my bios to an updated version, and I ran the creative software auto update from the website and updated the drivers and software and I'm still having the same issue. I am running a Dell XPS 400 system:?Dell DXP05 MotherboardPentium D830 Dual Core Smithfield @ 3.0Ghz2 gigs ramXFX Nvidia GeForce 7900GS 256mb Video Cardand X-Fi Xtreme Gamer Fatalty Pro Series Card?Any thoughts? I've read similar posts however none seem to be the same as my issue.
Hi,
Did this happen right out of the box or do you own the card for some time now?
Just in case, please ensure that the sound card is firmly seated on the pci slot. -
MSI P55-GD65 + Corsair XMS3 CM3X2G1333C9 = Random freezes,buzzes,reboots..
Hello..
My system specs are:
Mobo: MSI P55-GD65
CPU: Intel Core i7-860 (with Megahalems heatsink)
RAM: 2x 2x2GB (dual channel = 8GB in total) Corsair XMS3 CM3X2G1333C9
GPU: ATI HD5770
PSU: Corsair HX520W
The problem I face, is that I get random freezes (sometimes this is accompanied by a loud buzzzzzzzzzzzzzzz coming out of my speakers), or cold reboots. It's not something that is triggered by some specific action (e.g when I run a specific application or something like that), sometimes there are days that I don't get a single reboot, and other days that I get 4-5 freezes one after another..
I read in another forum, that this specific series of motherboards (GDxx) have some trouble dealing with certain memory brands, especially corsair. I don't know if that's true, just throwing it out there if someone has any similar experience to share..
So far I've tested my memory with memtest (overnight 8 hour test, it completed a few cycles), I've tested my cpu with a several hour prime95 small FFT test, which stressed my CPU in 100% for a few hours but that didn't trigger a freeze or a reboot. My temps are perfectly nice and normal..
Reading from Everest, I still use the AMI v1.0 version of the BIOS, but I don't tend to update things that work (there were a couple of times in the past that this only made things worse). I have set my bios settings to auto, do I don't know if I should play around with anything there, I must say though I've always been a bit skeptical about changing voltages or something (never played with overclocking in my whole life), fearing that I could damage anything, or at least lower its "expiration date"..
I hope someone expert can help me out..
PS. I must say this mobo is the second one I got, my first GD65 was replaced, but it had nothing to do with similar issues, I accidentally damaged the cpu socket. I can't seem to recall though, if I had such problems with my first mobo too..Quote

As gcanuck mentioned, in BIOS Cell Menu, Spread Spectrum should be disabled. If not done so, test each RAM stick individually in the primary black dimm slot. DRAM V. maximum is 1.65v's. It also may be that the CPU IMC refuses to cooperate. With only two sticks in the black slots, does this freeze problem continue? Another possibility is that the two RAM kits are of different chips even though they have the same specs. Are the batch numbers the same? Some may have Elpida chips, & the other kit Samsung.

Although another guy in another topic suggested even higher voltages, up to 1.79V (!!!!)
Whoever advised that is a moronic idiot! -
8800 GTX Randomly Freeze, Sound Continues (Card verified to be the issue)
So I just built a new system a few weeks ago:
MOBO: MSI P35 Platinum Rev 1.1
Video: MSI NX8800GTX-T2D768E-HD OC
Core: Intel e6850 Core 2 Duo
Case: Antec P180 Case
PSU: Antec True Power Trio TP3-550
So I can play a game for maybe 2 or 3 days straight(for hours on end), no problems at all.
Then out of nowhere, I get freezing after maybe 5 - 20 minutes of play.
The freeze is a full-video freeze, but the sound continues to play in the background.
I can't alt-tab or ctrl-alt-delete out of it, though I can ping the computer from a different box. There is no BSOD or error message of any kind.
The only way to get out of it is to hit the restart button on the computer.
After I restart the computer, and game, I play for another 10 minutes and get another freeze.
The cycle just continues after that, freeze after freeze.
The next day, I try to play again...and once again no freezes at all for several days.
I am using NVIDIA 162.18 drivers, but I have tried some older and newer ones.
This is on a fresh Windows XP Pro SP2 install, with newest drivers, and a few games.
I am under the assumption that the TP3-550 is plenty to run this video card.
It has the 2 six-pin PCI-E leads, and the motherboard accepts an additional 12V molex for additional power.
I also assume that if power was the issue, the freezes would occur at a regular interval.
What could be the issue? How do I go from no freezes at all one day, to every 15 minutes the next? I am thinking driver issues, but this card has been out for quite some time.
I've had the freezes occur in Company of Heroes, Fable, and Warrior Within
GPU Temp is running at 60 idle, 71 - 74C under load.
Though I have had it crash at 61, and 72 so I don't think that temp is the factor.
I know people sometimes have issues with the 8800 series freezing. It just irks me that it works great for days at a time, then randomly freezes.
Do I RMA it? Or just deal with the occasional freeze?Ok,
I now have 2 things. A better description of the problem, and results from a different machine.
I tested my 8800GTX(factory OC settings) on an AMD single core processor, Asus Mobo, and an Antec TP3 - 650 power supply (the same power supply as mine, but 100 more watts).
I ran human head on his box and encountered the exact same result (as below) within 5 minutes.
The nature of this freeze is as follows.
1. Running human head for 5 - 30 minutes at factory settings, causes the crash to happen 100% of the time.
2. Randomly, I will hear the audio pause for a second or two, and the graphics freeze immediately.
3. The music than starts back up, and continues to play, but the graphics remain frozen.
4. The mouse can be moved around the screen, and hitting the cntl-alt-del combo causes the mouse arrow to turn to an hourglass.
5. The hardrive lights continue to flicker.
6. 2 to 3 minutes later, I get a BSOD with a minidump, and the system immediately reboots.
I have yet to analyze the minidump, but I assume that it will be irrelevant.
What irks me is that I was able to verify this issue on 2 systems at this time, and I have already RMA'd the board to msi once. They were not able to verify it, though they say that they ran 3Dmark06 on it over several passes.
My problem is that 3Dmark allows pauses between tests, which may clear the memory, or allow it to cool, or whatever it does. Human head does not have this feature.
So now I have to pay for the shipping, and basically demand a new one, whether or not they can verify it using 3D mark.
The only other thing I can guess is that the True Power 3 550(and possibly the 650), is not powerful enough to power this card.
I would think that the 2X 18A(and 2X 19A on the 650) would be enough though, and my friend was running his test on much lesser system.
I'm out of options, and hope that I am not stuck with this faulty card. -
Mid 2009 13.3" Macbook Pro random freezing issue
Hi all,
I had a 2009 13.3" Unibody Macbook and last week purchased a 13.3" Macbook Pro. I had installed 4GB of RAM in the MB myself, and it had worked fine for the month I owned it.
I backed up my MB with an external USB hard drive using Time machine, restored from this backup on my MBP and moved the 4GB RAM over.
When using the MBP I get random freezes lasting between 1 and 3 seconds, occuring every 5 to 30 minutes.
Could someone please advise a good way to diagnose this problem further? I am guessing it is not the RAM as it worked fine whilst in the MB.I have an update!
I made an appointment with a local Apple Genius Bar and talked to a technian. He said it was neither the RAM nor the Hard Drive at fault.
His only thoughts were that a software issue was the root cause. I have been doing some serious investigating this morning and figured it out. Viewing system.log in Console shows:
SMS::infiniteIntTimerEventHandler ERROR: we have infinite interrupts, disabling
At exactly 5 minute intervals. These correlate with the freezes (to the second).
SMS refers to the Apple Sudden Motion Sensor. I disabled this by doing "sudo pmset -a sms 0" in Terminal, rebooted and everything is fine.
I have no idea why the SMS thinks the Macbook is falling every 5 minutes, but when it occures the hard drive heads are locked down to prevent damage, which is a perfect reason as to why iTunes would crash but Spotify (streaming internet music) does not.
Problem solved!
Edit:
In reply to some questions posted by other members (thank you by the way).
I did install EFI 1.7 update. I did not use the Migration assistance. At some point I will do a fresh install then pick and choose parts from a backup rather than using a full Time Machine Restore. This could still have been the root cause of the issue, but it is hard to tell.
Thanks guys!

Ipod shuffle randomly freezes....please help!!!!
My Ipod shuffle seems to randomly freeze after certain songs, or spots on the shuffle. I dont recall exactly when this first started, but it seems like ive tried everything. I have tried scandisk, defrag, resetting the ipod, updating it to latest firmware, and still nothing. The problem occurs whether or not I am in shuffle mode, or straight play. I would appreciate any help what so ever. I am at my wits end. I dont understand it at all. Scandisk detected no errors. Should I attempt to format it? Please help!!!!
Hello, Chris.
If the problem is corrupt files, there are a couple of things you can try.
Remove the songs from the shuffle's playlist, then refill the shuffle - but don't let the offending song(s) reload; we're trying to overwrite the memory. Then you can let these songs back on. If the problem continues:
If the songs weren't purchased from iTMS, try re-reripping/re-encoding them. Then reload them.
(These steps have worked with all but one song for me. I've never figured out why, probably just coincidence, but I have one song that would only play a couple of times before this started happening again. It's off the shuffle's playlist for good.)
If the songs were purchased from iTMS (and in another post I think you'd indicated they were) you can try to get them replaced or you can go the route of making an audio CD from them and reimporting the songs.
(I've never tried this, and one poster in this forum has indicated it will cause an unacceptable loss of quality.)
Good luck

Hi, I am experiencing random freezing of OSX, First I thought it was related to the latest flash, so I deleted it but the freezing keeps happening. Then I thought it was firefox so I switched to safari 5 but still it freezes.
Now the computer freezes randomly, some times while on the internet, some times while using mail.app, some times just sitting in the finder.
It freezes also every time I try to sync photos to my 3GS in itunes.
It also freezes after Steam is open for a while.
It is a unibody Macbook Pro, 17 inch, early 2009, 2.8 GHz Intel core 2 Duo, 4 GB 1067 MHz DDR3.OSX 10.6.4
If anyone has any ideas how to solve this it'll be much appreciated.I upgraded my MBP 2009 Unibody from the original 250GB HD to a 500GB 7200rpm HD, only to experience the dreaded freezing. Freezes randomly and shows the Beachball for about 30-60 seconds. So, I put my old drive in for a while. Then later, (about3 months), I got another 500GB 7200rpm drive. Installed it, and same problem. So I put it back like it was after having to delete a bunch of stuff to get it below 250GB so I could continue to use it. Later got a 3rd 500GB 7200RPM Drive and SAME PROBLEM! So, I put a 320GB 7200RPM drive and it ALSO has the same problem.
However, each time I did this, I used Disk Utility to copy the data using the Restore command to the new drive. While connected via USB, the drives all worked great. Put them INSIDE the MBP and they give this problem randomly.
I'm really getting sick of it.
Then on August 19, a "fix" was released as a firmware update. I just found this tonight and when I ran it, I was told "This computer does not need this update." So, I guess it's only for APPLE BRANDED Drives, not my other drives. I've tried Fujitsu, Western Digital, and Hitachi drives and they all give the same problems.
Anyone know what I can do to fix this? -
13" Macbook pro random freezing after upgrading hard drive.
i have a 2010 mbp 13" 2.4
I upgraded the hhd from the 250 to a 320 5400 RPM drive i cleared the cache did a clean install of osx 10.6 grabbed all the updates and then rolled my time machine to restore all my files.
But now it randomly freezes for about 4-7 seconds. It's extremely annoying and i can't figure out why. Short of a clean install any ideas on what might fix this?
ThanksThe AHT does test the graphics chips. Run the extended version and see if anything shows up in the form of an error code. Also, there may be a crash log in Console. Try to run something processor intensive so the Mac freezes, and then run the AHT. Heat could be a factor.
Do you have access to an Apple Store? If so, make an appointment at the Genius Bar and bring in your Mac for evaluation. They would probably have a more comprehensive hardware test they could run. If you get any error codes, bring those along.
It sounds like you could have some sort of hardware problem here. Since you are under warranty, it might be time to let Apple diagnose and fix it. It sounds like you may have had video issues during the first week of ownership with the original hard drive, and these may actually be independent of the hard drive.
Good luck!

MSI P35 Neo-F (MS-7360): Computer randomly freezes while playing games
Hi there,
I have reached the end of my technical knowledge right now and I'm not even sure if this area of the forum is appropriate. The problem:
While playing higher-end games like Crysis 2, Anno 1404, Mass Effect 2 etc. my computer randomly freezes and the last few milliseconds of sound are being looped on my speakers (kind of like a buzzing sound).
By "freezing" I mean that my computer becomes unresponsive to any action other than pressing the Reset-Button or holding down the Power-Up-Button (no reaction to Ctrl+Alt+Del, Alt+F4, Alt+Tab, no mouse movement... you get it).
There's no exact timing as to when these freezes occur. The fastest freeze happened after less than a minute of playing a game, slowes one (just today after switching to my newer case with better cooling) took about 2 hours.
This freeze only occurs while my System is under load. No freezes while browsing the web, using office programs, listening to music or watching videos.
System Specs:
Mainboard: MSI P35 Neo-F (MSI-7360)
CPU: Intel Core2Quad Q6600 @2.4GHz
RAM: 4x 1GB DDR2-800 Corsair XMS2
Graphics: Gainward GeForce GTX 560 Ti, 1GB GDDR5 VRAM
PSU: Antec High Current Gamer 620W (upgraded from Xilence XP600, 600W)
New CPU Cooler: Arctic Freezer 13 Pro (upgraded from OEM Intel Boxed Cooler)
New Case: Zalman Z9 Plus w/ 4x 120 mm Fans (Upgraded from a Case with only 1x 250mm side Fan)
2 Western Digital HDD (1x 2TB, 1x320 GB)
1 DVD Reader/Burner (unimportant for that error I guess)
OS: Windows 7 Ultimate 64-Bit
2 Screens: 1x 24" Asus VS248H and 1x 21" LG Flatron Wide W2240T
Since this error is bugging me for quite a while now and since this is not the first forum I'm trying to get help from, here's a list of steps i already took to get rid of it, obviously to no good use:
reinstalled games where the freeze occurred
updated all Drivers (including cleaning old versions in safe mode; also tried older drivers)
updated BIOS to v1.A0
Reinstalled Windows
bought new Case and CPU Cooler to improve Air Flow/Cooling
checked Seating of all components (took out, cleaned, reapplied thermal grease where neccessary, re-inserted)
cleaned old case of dust (obviously no problem in the new case, which is 2 days "old")
ran 7 sequences of Memtes86+ without any errors
ran Prime95 without any errors for about 45 Minutes
ran Furmark for 15 Minutes under full load (burn-in test) without any problems, even though my graphics card hit the 100°C frequency-cut level
ran Furmark and Prime95 simultaneously without any problems
took records of component temperatures and system voltages without noticing anything unusual (at least not after i switched to the newer PSU, which is about 1 Month old - yet didn't resolve the problem)
tested with cyclic removal of 1 RAM device to further rule out RAM malfunction
tested with only 2 RAM devices in dual channel mode (Slots 1 and 3)
tried to reduce RAM clock (800 MHz --> 667 MHz) to no avail
checked S.M.A.R.T. values of HDDs, no issues reported
tested without any background programs
raised/lowered voltages to RAM, CPU and Chipset in BIOS to increase logic circuit stability/decrease heat production
I need to mention: After I transferred my system to the new case, i was able to play longer than average compared to my old case. So I am guessing that improper cooling was part of the problem, yet improving cooling obviously didn't resolve it.
Since these freezes are really annoying and nobody could help me resolve this so far, I'm hoping to find some new ways of narrowing down the problem or even getting rid of it here.

Lets be realistic. A system with a 560TI is recommended to have a around 31Amps under full load, a CX500 would be sufficient.
Have you monitored your CPU and memory utilisation ?
As suggested before, test the GPU in another computer to see if the behaviour is the same.
Whew, I thought for a second there that my common sense had left me when I saw that 60-Amp-Post ^^
Yes, I monitored CPU and RAM usage, there is no recognizeable pattern to be seen and it almost never happens under full load.
I will see if a friend of mine can test my GPU on his computer, and I will test it underclocked right away.
Though one more question regarding that: Should I only underclock GPU Core Clock or both Core and RAM clock? -
Intermittent random freezing (mid 2012 MBP)
For the past year or so my Macbook Pro (mid 2012) has suffered from random freezes which require a hard reset.
Often these will occur only roughly once a week, but in the last couple of days (incidently since updating to 10.9.3, although such bursts have occured in the past and then settled down) it has been happening 4 to 5 times a day, getting to the point of being seriously disruptive.
I have, over the past few months, made several attempts to find the cause in vain. I am an experienced Mac user with a good understanding of computers, and I've never found a problem so mysterious to me. I'll break down first the symptoms and then what I have done to tye and find the cause.
Symptoms: Normally I will first notice that web pages aren't loading, but I can switch apps without problem. However, if I try and close an app or open another, that app then starts to hang. Progressively, everything starts to hang and I can no longer even switch apps, and everything gives me a spinning beachball. Eventually, even sound/music cuts out. Only a hard reset (holding down the power key) saves it.
Diagnosis: I have run all types of hardware checks, from apple's built in tests (fsck), RAM tests such as memtest, and third party testing suites which have checked the HD, RAM, CPU, GPU etc. All of them have come back 100% clean. I have repaired permissions, which also has no effect.
This made me think it could be a software issue. However, the crashes display no discernable pattern, and are completely (as far as I can see) un-reproducible. They have occured while I have been using a wide range of apps, and don't seem to be triggered by any particular action; e.g. they can occur while I am blankly reading a webpage or a pdf document. Further, the console shows absolutely nothing. The log messages appear completely normal, sometimes there are even no messages corresponding to within several minutes of the crash.
I haven't been able to verify if it is restricted to my user name, since generally the crashes are so intermittent I would have to use another username for several days, if not weeks, to really check this - something than is not practical given that I need the laptop to work on.
Does anyone have any idea what could be causing the issue, or anything further I could try to diagnose it? I am reluctant to take it to an applestore, as it is out of warranty and I can't think of any tests they could try that I have not.OGELTHORPE wrote:

An Apple store genius bar appointment and evaluation is for FREE! You have no idea what type of tests they may have, so make an appointment.
Thanks for pointing that out. Until very recently I lived in a country where there are no Apple stores nor Genius bars, so I wasn't aware of that.
I've tried safe boot, but as I said the problem is intermittent enough that it's not clear if it helps, and working continuously in safe boot to see isn't really an option.

Macbook Air 2011 11" - random freezes. Roaming wifi causing it?
I have MacBook Air 11" Mid-2011 (4GB RAM, 128GB SSD, i5). Ever since getting the machine I've experienced random freezes - spinning beachball, screen becomes unresponsive, holding the power button to force it to close being the only thing I can do. The console logs don't show anything that indicates a problem. They just stop logging anything until I restart. I took it to an Apple store Genius while still under warranty and they kept it in for a few days and ran a suite of tests and found nothing.
The problem was completely random and unreproducable. Sometimes it would happen a few times in a row, then nothing for weeks. Also, it was only happening when I was staying in a particular hotel during the week for work. It was Hilton hotel with the wifi being provided by BT Openzone. It would only happen there, never at home, family members house, Starbucks (which also use BT Openzone here in the UK, airports).
I recently made some changes to my home wifi setup and the problem has reappeared, but this time at home. Where previously I just had an Airport Extreme, I have now extended the network over ethernet powerline to a second wifi access point. The second wifi access point has the same SSID as the main network.
All my wireless devices should seamlessly switch between access points as I move them around the house. Our iPhones, iPads and Dell laptop seem to have no problem doing this. When I move away from one access point, once the signal strength drops to certain point, the device connects to the second access point. The MacBook Air also does this, but it seems to freeze if I am in an area where the signals are overlapping. This also describes the situation in the hotel. The BT Openzone hotspots were spread across the hotel. If my room was in an area where the signals from access points were overlapping I would be more likely to experience the freeze.
If I look in the Wifi logs I can see messages stating that some sort of threshold has been reached and the wifi is starting roaming. These messages are always present at the time of the freezes.
Has anyone else experienced this problem? Is it something Apple would fix eventhough I'm now out of warranty? If it could be a hardware problem, would replacing the wifi card myself help?
