Computer freezes every hour

I built my brothers computer about 2 years ago and there were no issues. Awhile ago he uninstalled itunes from the C drive and installed it on the F drive. Well when he did this is when the computer started freezing every hour. Whether that was the exact
cause or not, I'm not sure. I tried reinstalling it back on the C drive but it still freezes. I retrieved the admin logs for when the error occurred. There were 5 events. I have them zipped up but I don't know where I can upload them on here. Any help would
be most appreciated, I've spent hours looking for a solution.

Hi, sorry for the delay. It's been a busy couple of days. I was toying with my brother's computer yesterday and this is what I came across. The computer has a Crucial M4 64GB SSD (C: drive) which is used for the OS basically. He also has an external HD (we
will call it F drive). Whenever I unplug the external and manually restart the computer, it restarts as normal. However, when it freezes and I restart the computer by actually shutting down the comp, it doesn't recognize the C drive. It boots to the bios but
I don't have the ability to change the boot order because it doesn't recognize the C drive (the F drive is unplugged). Once I plug the F drive back in and restart the computer, it will boot up as normal. The F drive is purely for programs, everything OS related
is on the C drive.
I also tried to install something from windows update but it got stuck, blue screened (I wasn't able to see what it said) and eventually froze on checking for updates. I'm suspecting it may be a hard drive failure but I'm not 100% certain.
I've never used skydrive so I hope I did it correctly. I just uploaded the zip file. Thank you for all your help.
Here's the link: https://skydrive.live.com/embed?cid=00B26060B7C7843A&resid=B26060B7C7843A%21114&authkey=ACeBr9_aIUXrUfM
There are only 5 events covering 7 mins on one day so no iformation of use in it try it again
Please provide us with your Event Viewer administrative logs by following these steps:
Click Start Menu
Type eventvwr into Search programs and files (do not hit enter)
Right click eventvwr.exe and click Run as administrator
Expand Custom Views
Click Administrative Events
Right click Administrative Events
Save all Events in Custom View As...
Save them in a folder where you will remember which folder and save as Errors.evtx
Go to where you saved Errors.evtx
Right click Errors.evtx -> send to -> compressed (zipped) folder
Upload the .zip file to skydrive or a file sharing service and put a link to it in your next post
If you have updated to win 8.1 and you get the error message "the system cannot find the file specified" it is a known problem. The
work around is to edit the registry. If you are not comfortable doing this DONT. If you are, backup the key before you do
Press Win+"R" and input regedit
Navigate to:

Everything was ok for 4 month. A month ago I've start experiencing freezes 1-2 a day and now it became worse, every hour. I've try to repair disk permissions, repair disk. Does anyone know how to fix this issue?
I read in one of the website that some people fixed this issue updating ssd firmware. But I'm not sure where to get firmware for my ssd.

Sorry I missed that.
This is what I think is happening:

There are two options, keep the Time Machine HDD connected full time or turn Time Machine off and on only when you want to make the backup.

Computer freezes every time i try to copy single song from a cd

my computer freezes every time i try to copy even a single song from a cd onto itunes. I've reinstalled itunes and still have the same problem. i read somewhere that you shouldn't have 'third party extensions' but don't know what what means. Can someone please help in a fashion that you might do for a child? Thanks oh so much!!
pc Windows XP 8gig hd

It may be the drive is set to PIO instead of DMA. I;ll try to descrabe in steps what to do to check this.
1) Goto control panel>system>hardware tab>Device manager
2) Double click IDE ATA controllers
3) Rightclick "Secondary channel" and hit properties this is usually the channel most CD ROMs are on, you system my vary
4) Goto the "Advanced settings" tab and see if it say PIO. If it does goto step 5,
5) Hit "Cancel" and back in the device manager where you see "Secondary channel" rightclick it and hit Uninstall
6) close everything and reboot the PC so windows will load the channel back up in DMA mode

Macbook freezing every hour

I've had my laptop for about a year and a half now and recently its just started freezing every hour and the spinning wheel appears but i can still move the cursor, this lasts for a couple of minutes and then everything starts working fine again. I havnt dropped it or done anything different from how i usually treat it and havnt downloaded any new software recently. Anyone know what might be the problem or how I could fix it? Its pretty annoying when im trying to work.
Thanks

Open your Activity Monitor.app.
Leave it open so that you can see the contents of the window.
Now click the banner for the CPU% so that it is sorted showing the highest usage at the top of the list.
Next step, play the waiting game =) you need to make sure that you can see the list in the Activity Monitor when the time comes around that everything is freezing.
Look at the list, when it freezes up and see what is at the top of the list for CPU usage. Also note what the CPU usage is listed at. (write down the top 5 items and the cpu usage)

Snow leopard freezing every hour at the same time

Hi all,
I've been having freezing problems with my macbook pro. I'm running 10.6.4 and have noticed that every hour to the exact minute, my computer will be unresponsive for approximately 30 seconds to a minute, and then returns back to normal.
The time that it freezes will vary from day to day, ie some days it will freeze at 7 minutes past the hour all day, other days it will freeze at 19 minutes past the hour every hour.
This has only been happening for possibly the last month, and I have no idea what is the cause. I've used console to see if get any error messages, but nothing is coming up. I'm not using time machine. I've tried restoring disk permissions.
I'm not sure whether this is a macbook pro related thing or a snow leopard related problem so excuse me for posting this in both forums.
Please help!

You're likely to need it, sooner or later. If you suspect hardware problems, for example, the +Apple Hardware Test+ on it is tailored to your Mac's hardware. If you can't find it, AppleCare will send you a replacement for a nominal charge.
If the file system on your HD is ok, and the hang occurs at exactly 60-minute intervals, then it must be related to some periodic process running on your Mac.
I'd have expected another message in your logs. There may be something that doesn't show in Console's +All Messages+ selection.
In the Console sidebar, select your system.log file; it's the first one shown in the Files folder. The I/O message should be there; confirm that they occur every hour, and see what other messages are near it in time. Again, if theres's anything dire-sounding, copy and post here.
Also open the various folders, looking for one or more named HangReporter. If you find any, look inside. Each process that generated a log there will be named in the sidebar, along with the date & time. That may provide a clue (please don't copy a whole log here; just the beginning page or so).

Problem - computer freezes every time a 3D game / Wine game is run

Hello. My brother's computer is a quite powerful machine. He would be very satisfied with it if it wasn't for one thing: it freezes every time he runs any 3D game or any game using Wine.
I have tried to do some troubleshooting, but after long time I still cannot find the cause. The problem persists. No update has fixed it yet.
Some 3D games seem to run, some don't. I have tried AssaultCube and it worked, but when I tried Sauerbraten it froze.
Wine games seem not to work at all, or at least that's my general impression. As a test, I tried a freeware DirectX 7 game. Froze straightaway. More complex games of course also froze.
The problem seems to be related either to hardware or to some NVidia-specific stuff. I tried a test run of XP on this computer. It ran when it was a clean install, but when I installed NVidia drivers, it didn't boot again correctly. There was no error description as far as I remember.
I have swapped a power supply to a higher wattage thinking that it maybe was energy starvation that took the system down. No luck.
Output of different commands:
"hwinfo --short": http://pastebin.com/Sj8SbvZy
"lsmod": http://pastebin.com/dtchwqAF

One more thing. Even though it's a 64-bit CPU, I'm running a 32-bit system. Would that create a problem? From what I've read online, it doesn't really seem to make that much of a difference.
Please help me with this. I really don't know what to do.

hello again.
glxinfo looks good and normal
Right.. i have been reading bout similiar issues ..like that of your system freezing..
a reported fix would be to
echo 1 | tee /sys/devices/system/cpu/sched_mc_power_savings
as root
and add it to the /etc/rc.local for it to be applied every boot up..
Link of where i have gotten the info from
https://bugs.launchpad.net/ubuntu/+sour … bug/151382
Apart from that , i have noticed your kernel isnot up to date.. Please run your updates.. the latest kernel in the core repo at the time of writing is 2.6.36.
Hope it works out for you
and if the above doesnt work out..
i would need to see your

I did a system update and now my computer freezes every minute

As we speak my computer is freezing at 1 minute intervals. It works fine for 1 minute and then stops anything I am doing (even if not online) and the rainbow circle comes on for another minute freezing anything I try to do. This is continuing as I am typing this, making this a long process. I think it has something to do with my system update.
I did a system update last night and it said it was going to install and restart my computer. But an hour later when I checked on my computer it had been stuck on the outerspace screen with nothing on it so it never restarted and I had to turn it off manually. After I turned it on myself I noticed it acting this way so I thought maybe it was because it could not restart to complete the update proccess so I tried to restart it but the computer would only get stuck on the same screen again. I tried it several times, it wouldn't shut down or sleep either when commanded to. I let it rest all night and this morning tried to restart it again and finally it did but the freezing continued. I don't know what is wrong or what to do. I have to type up a lot of homework and I cannot do it if it freezes on me while typing and if I try to save and it freezes again. Help!
I also looked for more system updates and it said it was already up to date.

No, it is set up to only sync selected books. But I even tried to just remove all books and not sync any and it won't let me do that. It always acts like it is syncing correctly, then all of a sudden all books I'm trying to remove get selected again.
I have a total of 20 books. 9 books are on the phone. I am trying to remove all but one of them and then add one other that currently isn't on the phone. I tried removing the ones I don't want first and syncing with the intention of adding the one I want after the others are removed. It wouldn't remove them. I tried unchecking the box that tells it to sync the books at all and remove everything and when I hit sync it just reverts back to the checked box and the 9 original books.

Computer freezing for hours while repairing from installation disk

My computer has been running slow so I ran disk utility and it said something was corrupted and I needed go through the repair process through my installation disk (snow leopard). It went through and did the repair disk fine. I went and did repair permissions and after a couple of minutes it froze. I could move the mouse, but it had that spinning wheel and wouldn't let me click on anything. I shut it off with the power button. That was last night. This morning I started my computer, and tried repairing the permissions without the installation disk. I was hoping whatever needed to be repaired from the disk was done so already. It said it would take 18 minutes, and 90 minutes later, it still wasn't finished. I stopped the repair and restarted through the disk. It has now been two hours and it has frozen at the same spot but this time the cursor is normal. It says "open error 1: operation not permitted...dingDocumentView.nib/keyedobjects.nib" and then the next one, the one it freezes on, is "permissions differ on applications/system...should be -rwxrwxr-x, they are -rwsrwxr-x." I can't read the rest since it is still frozen (I'm on someone elses computer right now). Any ideas on what to do? My apple care has run out and my only problem right now is that it is running slow, so I don't think I would bother getting it professionally repaired, but maybe my computer is dying?

Others have (in the Mac Pro forum) noticed this bug in Disk Utility on the Intel version install disks. Your easiest fix would be to reinstall OSX on you Macbook disk, boot it, mount the disk image from the USB drive, and use the Migration Assistant to copy over all your accounts and data files.

Does Time Machine wake my computer up every hour?!

I am finding mixed answers...
Does time machine wake up the computer to do the hourly backup?
It seems to do this, as it made eight backups last nite.
if so, what's the sense? any way to prevent this?

Hello all:
I rarely make statements without qualifying them. However, TM does not wake a sleeping computer. If a computer is waking up, something is causing that to happen besides TM.
Barry
Edit: I believe that dwb has a good thought. Go to system preferences>energy saver>sleep and see what you have indicated the system should do.

IBook freezes every hour

while on a public WiFi network. Any public WiFi network - actually I don't have access to private ones. It looks like the laptop momentarily looses connection, then Safari stops responding, then Finder stops responding and then the only solution is reboot. This pattern started sometime at the beginning of the summer. Any ideas?
Eugene

In the meantime, a possible workaround to rebooting is to use one of these lines in terminal...
sudo ipconfig set en1 BOOTP;sudo ipconfig set en1 DHCP
sudo ifconfig en1 down;sudo ifconfig en1 up

Programs keep not responding, computer freezes often, apple mail won't open

Starting yesterday my computer has been running very slowly. it takes almost 15 minutes to start up and then programs won't open or will quit unexpectedly or not respond. Not to mention that my computer freezes every 30 seconds or so. I have 4gb of crucial ram that system diagnostics say is ok. i don't know what is wrong.

Have you tried opening Mail from the Applications folder. The Dock alias may be corrupt.
Try a restart.
Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.
Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
Isolating an issue by using another user account
If the problem is still there, try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.

MacBook Pro freezes every 15 minutes after Mavericks upgrade

After upgrading to OS X 10.9.3 my computer freezes every 15 or so minutes in the middle of working. The keyboard and touch pad stop working and the mouse curser disappears. I'm using Ableton audio software and the audio will continue playing and looping normally but I loose any control to stop the audio or the program and I can not switch windows or even control volume. The only way to stop it is to hold down the power button and reboot. When restarting I tried pressing the command option +P +R through 3 whole sequences and still once I begin working again it freezes again. This has never happened in the 5 or so years of owning this computer and everything worked great while using lion. Only after installing the new upgrade of OSX did it start to do this. Any help would be appreciated. I live far away from any Mac store or Genius Bar.

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter "BOOT_TIME" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Note the timestamps of the BOOT_TIME log messages, which refer to the times when the system was started. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Select the messages logged before the boot, during the time something abnormal was happening. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
For example, if the system was unresponsive or was failing to shut down for three minutes before you forced a restart, post the messages timestamped within three minutes before the boot time, not after. Please include the BOOT_TIME message at the end of the log extract—not at the beginning.
If there are long runs of repeated messages, please post only one example of each. Don’t post many repetitions of the same message.
☞ When posting a log extract, be selective. A few dozen lines are almost always more than enough.
☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
Step 2
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A crash report has a name that begins with the name of the crashed process and ends in ".crash". A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent of each. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
☞ If you don't see any reports listed, but you know there was a crash or panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
☞ Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

13 in macbook pro (early to mid 2011) : after the update, computer freezes with spinning wheel every 30 seconds first with safari and now with all the applications. I don't have any programs installed and still had good enough memory on the RAM.

After the update of my 13 in mac book pro (early to mid 2011) , it freezes every 30 seconds with the spinning wheel and now it just freezes. Ive never had this problem until I recently updated. Also, I just checked now for available update ( which there was one), the update would process till the last step and it shows it cannot be expanded? Now my computer wont even restart (just have a grey screen with a cursor). Can someone please tell me what the heck is going on with my computer?
I also checked the memory and it showed available memory was over 1.5 GB. I dont have any programms installed and do not have backup yet ( dont really need it anyways)
Problems: first with spinning wheel every 30 seconds and now whole computer just freezes when I restart, it only shows grey screen after the starting sound or it takes about 8 to 10 minutes to restart.
This ALL happened right after the update with google chrome crashing. I know my apple care plan expired so I cant even go to genius bar. Do you guys know how much it would cost to get it fixed ? Or any recommendations I can do to fix this?

My Mac computer freezes after running for 15 min even after seeting the energy saving to 3 hours. Any ideas how to stop the freezing/

Hi Teodorafrombc,
Thanks for visiting Apple Support Communities.
If your computer is becoming unresponsive, you may want to see if specific applications are causing this behavior. Try using the Force Quit menu to check for unresponsive applications:
Using the Force Quit feature of OS X makes an application close, even when it is not responsive.
Important: Normally you should not need to force quit an app to close it. When an app is forced to quit, any unsaved changes to open documents are not saved, so try these methods to normally close the app first:
Choose Quit from the app menu. For example, in Safari, choose Safari > Quit Safari.
Choose Quit by right-clicking or control-clicking on an app's icon in the Dock
You can find the article with these steps here:
OS X: How to quit an unresponsive application using Force Quit
http://support.apple.com/kb/ht3411
If your display is going blank or seems to be going to sleep unexpectedly, try these steps first:
Reset the system
You can reset the Mac's parameter RAM and SMC.
You can find the article with these steps and more information here:
