Extremely slow computer

hey all,
My MacBook Pro has been running VERY slow lately. The internet is the slowest of all, and it does not matter what network I am on because it is always slow. Also, anytime I run any program, it sounds as if my MBP can barely run. It becomes really loud and sounds as if it is working very hard. Whenever I want to put it to sleep, it takes around 10-15 minutes for it to finally go to sleep after I push the option. And right before this message, I put it to sleep and closed the lid, and when I opened it, it completely shut off.
All this started happening when I installed some updates a week or so ago. I use this computer for college, and currently, I have 220 GB left with no extra programs on it besides Word, Powerpoint, etc.
Any help would be appreciated Especially since the nearest Apple store is hours away.

Well it sounds like the HD is failing. The first thing to do is back it up immediately.
What you can do first is Disk Utility (Applications-Utilities-Disk Utility) highlight the HD on the left and then check the S.M.A.R.T. status, it should say Verified. If it doesn't without doubt it's in trouble. However it still can say Verified and still NOT be OK. After you have completed Disk Utility then run Apple Hardware Test. If the hard disk has errors then depending on the error it may be able to be fixed however it probably should be replaced.
Once you have run AHT please let us know errors or the results of your tests are.

  • Extremely Slow Computer Shutdown (WinXP with iTunes7)

    I am running WinXP Media Center 2005 (SP2) on an Intel Pentium D-950 with 2 gig RAM. Prior to installing iTunes 7, the duration of the shutdown procedure could be measured in seconds. However, now that iTunes 7 has been installed, the shutdown process takes more than 3 minutes. BTW, if I uninstall iTunes7, then everything goes back to normal. Do you have any ideas for fixing this issue?
    Intel Pentium D 950   Windows XP Pro   Media Center 2005 SP2

    i think we'd better check to see if it's a systemwide issue on the MCE machine, or if it's associated with a specific user account.
    (i'm leaning away from the MCE conflict theory just at the moment, because i haven't seen the flood of reports i'd expect with a general conflict like that ... we'll revisit it if necessary, though.)
    let's try some experiments.
    head into your user accounts control panel and create a new user account with full administrative rights. (there's help documentation on how to do that at the left of the control panel screen.) while you're in that control panel, switch off "fast user switching" in your logging-on preferences.
    now log out of the old account and log into the new account.
    (experiment a)
    first try shutting down the PC from inside the new account.
    does it shut down slowly, or in a more rapid fashion than the usual user account?
    if it shuts down rapidly, let's try another experiment.
    (experiment b)
    launch the PC. go into the new user account. launch itunes. eventually, you'll see a blank library screen. don't be alarmed, your music is in the other library in your other user account.
    shut down itunes.
    (by launching and shutting down itunes, we will have created itunes preference files, and various other things that weren't there before.)
    now try shutting down the PC again. is it still a rapid shutdown, or has it slowed down again for you?

  • Extremely slow computer even after replacing hard drive. Please help.

    The problem started when I upgraded to lion (I think). I also run VMware fusion with windows 7 so maybe a virus? I ran disk utilities, followed suggestions on these communities to no avail. Our IT person and then apple support told me I should replace the hard drive. So I did. I played around a little bit and everything seemed good. Then I did a full restore from time capsule and everything is going downhill again. Any suggestions on a next step?

  • Macbook Pro 2011 extremely slow wondering if hard drive failure

    Hello, I want to start off by saying I'm not a huge computer guru, so that is why I'm coming here first. My Macbook Pro worked very well for a year, and then it has slowed down drastically. I've always been a windows user so mac is kind of foreign to me, but I'm trying to learn.
    Some problems I've encountered are 1. Extremely slow running whether internet related, or just an application. I have checked the activity monitor and nothing is hogging up my memory. 2. Spinning wait cursor (rainbow circle) when I try to do ANYTHING. It takes minutes to start computer once it makes it to home screen. The circle just spins for a few minutes. Even just web surfing it's there. 3. Battery drains from 100% to less than 20% in 30 minutes, which again is annoying. 4. When battery drains the fan turns on and seems to drain battery even faster. 5. I get a lot of random errors forcing shut down of programs. I have ignored this problem for two years by not using my laptop or using it very minimally, but I am going to be needing a laptop again for school and not just my iPad and phone so I was planning on taking my macbook to genius bar, but wanted to check here first since Apple is an hour away. Plus I want to be able to use the piece of equipment that I spent a decent chunk of change on. I used time machine to back up everything today. I know its not a space issue as I have 300+ free GB on hard drive. I have tried to read through similar posts, but its overwhelming so I came here to post my own question.
    I ran disc utility and there were some errors, which were able to be corrected after a couple tries. Computer still slow though when trying to do anything and running rainbow circle.
    In recovery mode I reinstalled OSX
    I was finally able to install updates after completing the above that were not able to be installed before.
    I ran etre check, this is the report that came up:

    Basically I'm wondering if anything sticks out in this report. I was thinking it could be a possible hard drive failure. I know my computer has been dropped on the floor at least a few times. Thoughts are appreciated. Thank you for your patience.

    Eab, I feel your pain! I am replying simply to share my similar ongoing experience with my early 2011 17 inch MacBook Pro, running Mavericks with seeming ample hard drive space, [applications requiring less than 100GB, about 200GB data (total drive space of 500GB)] & 4GB RAM. (Disclaimer: I am not a wise or computer-savvy mac guru - simply a fellow traveler who has had a very similar set of problems - apps taking forever to load, rapid battery depletion & super overheated MacBook.  While I am a Genius Bar groupie, getting to the Apple store is, for me, akin to an antarctic polar expedition (i.e. problematic). Having spent endless hours struggling with a similar issue, I offer you a synopsis of my struggle/experience.
    STEPS TO DATE:
    1.Installed several memory utility programs (Daisy Disk &  MacCleanse) system
    maintenance program to regularly and thoroughly empty application caches (Adobe apps & internet browsers being tremendous hogs), identify and remove language elements and other redundant space hogs, etc.   Result: Small, but real improvement when I forced myself to perform a "scan and delete" session every second major computer run (typically about 6-8 hours in length). However, this did nothing to help the problems regularly detected when I run the Disk Utility which almost invariably demonstrates disk permissions that need to be repaired and, with increasing frequency, has demonstrated actual disk errors that require restarting and walking through a disk repair protocol. I did bring it to the Genius Bar where they kindly reinstalled Mavericks which they could do in about an hour versus the several hours that doing this at home requires.  This did identify that my RAM was, on fact, a limitation on the speed at which I could run certain apps.
    2. My next move was to install an additional 4GB of RAM. I bought the new RAM on eBay for about $90 because, with 3 kids equipped with MacBooks & iPhones, I simply couldn't afford the official Apple RAM. I even installed it myself, with the help of a YouTube video. Result: Giant improvement in speed (starting up or switching apps. If I had realized how simple it turned out to be, I would have done it well over a year ago. Some minor improvement in the overheating problem, but persistent problems with disk permissions continually requiring repair and periodic disk repairs (using Disk Utility) required.
    PLANNED FINAL INTERVENTION:
    3. I am purchasing and installing a solid state drive (ssd) and simply chucking the original hard drive, after considerable discussion with my savvier mac friends. It has become clear to me that, sadly, every hard drive has a finite life affected by a variety of factors. I am, in fact, hard on my equipment - running multiple graphic apps simultaneously, transferring massive GBs of data between my laptop, time capsule and an array of hard drives. I will let you know how it goes, but can share that the decision to get a solid state drive followed many conversations with multiple Mac guru-types (in the hope of saving you similar painful tribulations). The cost varies according to the size of the drive, but $400-$500 would buy a reasonable starting size. I am waiting for Black Friday sales, myself. Amazon (where I will likely purchase the ssd) is already offering a number of pre-Black Friday deals.  While I don't really feel like putting out that amount of cash, I reassure myself that a new drive will almost certainly solve the disk errors (with a solid state one offering more durability) & will help me prolong the life of my MacBook Pro by a couple of years hopefully. It beats buying a new Apple MacBook only three and a half years after investing close to $3k for this one!
    I am certain that more experienced forum users could point you to software that could help defragment your drive or may be able to offer other solutions. I've simply had enough of struggling with burning thighs and head-banging behavior triggered by slow performance. I hope this is helpful to you in some small way.  The war is not yet over, but I'm feeling good about the battle plan!

  • Extremely slow Safari, Mail, Firefox,etc.

    I have been experiencing an extremely slow computer. Safari, Apple Mail, Firefox, Apple App store, iTunes store, any app the requires the internet. Sometimes it takes Google.com 30 seconds to load. Apple Mail routinely times out. After loading a web page and then selecting the back button, it takes over 30 seconds to reload the previous page. I have turned off iCloud.
    I contacted my ISP,  two service calls to check the line and they replaced the cable modem. The results from Speedtest.net were +25Mbps download so their advice was to call Apple.
    I have been getting a Recoverd files folder in the trash when I start up the compter. Activity monitor only shows, activity in Finder, Firefox, and Acitvity Monitor, so nothing else is running in the background.
    Any suggestions? Have I missed something?
    Should I do a Clean Install?
    iMac, 27 inch, 3.4 Ghz Intel Core i7, 8GB memory,  Mac OS 10.8.2
    Thank you.

    Boot into Recovery by holding down the key combination command-R at the startup chime. Release the keys when you see a gray screen with a spinning dial.
    Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with networks that require any kind of authentication other than a WPA or WPA2 Personal password.
    From the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. While in Recovery, you'll have no access to your saved bookmarks or passwords, so make a note of those before you begin, if they're needed for the test.
    Test. After testing, reboot as usual and post the results.

  • Ever since my upgrade to lion 10.7.3, and iCloud, my macbook is running extremely slow. What can I do? It doesn't seem like my contacts are pushing through to the computer from iPhone.

    Ever since my upgrade to lion 10.7.3, and iCloud, my macbook is running extremely slow. What can I do? It doesn't seem like my contacts are pushing through to the computer from iPhone.

    Then your basic issues are: too little RAM, incompatible software, dysfunctional installation.
    Add more RAM or kill as many programs that you use until the computer is running normally.
    See App Compatibility Table - RoaringApps. Upgrade any old software.
    Reinstall OS X:
    Reinstalling OS X Without Erasing the Drive
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Reinstalling OS X Without Erasing the Drive
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list.  Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu.
    Reinstall OS X: Select Reinstall OS X and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    Alternatively, see:
    Reinstall OS X Without Erasing the Drive
    Choose the version you have installed now:
    OS X Yosemite- Reinstall OS X
    OS X Mavericks- Reinstall OS X
    OS X Mountain Lion- Reinstall OS X
    OS X Lion- Reinstall Mac OS X
         Note: You will need an active Internet connection. I suggest using Ethernet
                     if possible because it isthree times faster than wireless.

  • My external HD of 1TB is not being recognized by the iMac and when after a long waiting period it does, the whole computer becomes extremely slow. Do I need any particular add-on to make it workable?

    My external HD of 1TB is not being recognized by the iMac and when after a long waiting period it does, the whole computer becomes extremely slow. Do I need any particular add-on to make it workable?
    Before I updated to OS X Mavericks I was using another external disk that was getting disconnected ocasionally so I bought a new ADATA HD710 portable 1TB Drive and moved the files to it. This new drive which is supposed to be OS X Mavericks compatible takes minutes to show the files especially when opening second and third level folders which has made mu iMac unusable
    What should I do?

    Your Mac should be able to recognize many different types of drives (including Windows-formatted drives) immediately for Reading, provided they are in good working condition and not damaged. There should be no need to transfer to a different type of drive.
    If there is no recognition of this drive, see if it can be seen in Disk Utility.
    If your aim is to transfer the data on it DO NOT use ERASE or PARTITION as these will completely erase all the information on the Drive.
    If the drive is present while the Mac sleeps, it is likely to drop out and not be seen any longer, especially if it is a USB-powered drive.

  • I installed the latest update of iTunes and now my computer is extremely slow and it freezes, What should I do to make it run  as usual?

    I installed the latest update of iTunes and now my computer is extremely slow and it freezes. When I click on the itunes icon, nothing happens, if it opens is a long time afterwards. Most of the time it does not even open, but the computer is very slow. It is a PC desktop running windos xp.

    my final cut is running extremely slow after having for 6 months.  I use external hard drives and save nothing on my computer.  it takes a long time to render now. do you think something is wrong with computer. took it to mac store but they fail to help me.  I have a 13 inch mac book pro 10.6.8 8gb 2.3 gfz intel core i5

    What did Apple tell you about what they did (or did not) find here?
    See if working on the main disk is any faster.
    USB2 is glacial, as I/O interconnects go.  And USB2 disks have been known to fail, or sometimes to drop back to USB1 speeds, too.  FireWire 800 is substantially faster than USB2, but still not as fast as the internal drive connections can provide.
    Put another way, start varying your configuration, and see which configuration changes (still) have the problem, and which don't.

    First, tell Apple about your problems... with details... and hope for an update that fixes your slowness
    Second, Yosemite sometimes has problems, often related to "default" permissions needing to be changed

  • I purchase this approx 6 yrs ago, recently had to purchase Mac OS X Snow Leopard for my daughter new IPOD to work.  But this crazy computer is extremely slow, why??? Please help.  Very fustrated!

    I purchase my Mac approx 6 years, recently purchase Mac OS X Snow Leopard disk for my daughters new IPOD to work, computer is extremely slow, others refuse to use it, why is it slow, I know very little about this computer and have hated it from day one! Please help.  The most I have on this computer would be photos, never downloaded movies, and have approx 40 songs.

    The best option to make it faster would be to manually go through and erase all of the junk (files you never use) from the computer. If you want a much faster way (depending on how many files you have, this can take much longer), you can copy the files you'd like to keep to an external HD and then erase and reinstall OS X.
    Erase and Reinstall OS X using the OS X Install DVD
    Note: This will delete all data on the disk. Back up important files before continuing.
    Erasing and then reinstalling OS X can give you a fresh start, making your computer exactly as it was whenever you received it from Apple. This can solve various problems such as corrupt system files.
    Insert your OS X Install DVD into the computer's built-in disc drive (if applicable) or your computer's external USB disc drive.
    Shut down the computer by going to Apple () > Shut Down…
    Select Shut Down or allow the computer to shut down automatically.
    Plug in the MagSafe power adapter into a power source and then connect it to your Mac if you have not already done so.
    Press the Power Button to turn on the computer.
    Press and hold the D key on the keyboard until the Recovery partition loads. If this does not work, shut down the computer, press the Power Button to turn on the computer, and then hold in the Alt (⌥) button immediately after you press the power button. Then, select the Mac OS X Install DVD to boot from the Mac OS X Install DVD.
    Select Disk Utility and then choose Continue.
    Select your startup disk (Macintosh HD by default) from the left.
    Select the Erase tab.
    Choose the Format pop-up menu and choose Mac OS Extended (Journaled), enter a name for your disk, and then click Erase.
    After the disk is erased, choose Disk Utility > Quit Disk Utility.
    Select Reinstall OS X and then choose Continue.
    Follow the instructions.
    I hope I helped.

  • Anyone having trouble with computer running extremely slow with the color wheel continuously spinning.?

    Updated with Yosemite and think that's when my problems started with my IMac being very slow.  The color wheel keeps popping up and spinning not allowing me to move forward on typing or moving between websites etc.  Extremely slow and never had this problem before Yosemite.  Any real answers to this out there?  I was on the phone with apple support for two and a half hours the other day and it's not made any difference in what the tech had me do to resolve this issue.

    1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
    The test works on OS X 10.7 ("Lion") and later. I don't recommend running it on older versions of OS X. It will do no harm, but it won't do much good either.
    Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
    2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
    There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
    3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
    You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
    In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
    You may not be able to understand the script yourself. But variations of it have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message. See, for example, this discussion.
    Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
    4. Here's a summary of what you need to do, if you choose to proceed:
    ☞ Copy a line of text in this window to the Clipboard.
    ☞ Paste into the window of another application.
    ☞ Wait for the test to run. It usually takes a few minutes.
    ☞ Paste the results, which will have been copied automatically, back into a reply on this page.
    The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
    5. Try to test under conditions that reproduce the problem, as far as possible. For example, if the computer is sometimes, but not always, slow, run the test during a slowdown.
    You may have started up in "safe" mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
    6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.

    Copy the selected text to the Clipboard by pressing the key combination command-C.
    8. Launch the built-in Terminal 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 and start typing the name.
    Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
    9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
    exec bash
    and press return. Then paste the script again.
    10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. If you don't know the password, or if you prefer not to enter it, just press return three times at the password prompt. Again, the script will still run.
    If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
    11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, a series of lines will appear in the Terminal window like this:
    [Process started]
            Part 1 of 8 done at … sec
            Part 8 of 8 done at … sec
            The test results are on the Clipboard.
            Please close this window.
    [Process completed]
    The intervals between parts won't be exactly equal, but they give a rough indication of progress. The total number of parts may be different from what's shown here.
    Wait for the final message "Process completed" to appear. If you don't see it within about ten minutes, the test probably won't complete in a reasonable time. In that case, press the key combination control-C or command-period to stop it and go to the next step. You'll have incomplete results, but still something.
    12. When the test is complete, or if you stopped it because it was taking too long, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
    At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
    If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
    13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
    14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I may not agree with them.

  • My computer is extremely slow, with the rainbow wheel appearing with every click. It is one year old, and has all the most recent updates. Why is it so painfully slow?

    My computer is extremely slow, with the rainbow wheel appearing with every click. It is one year old, and has all the most recent updates. Why is it so painfully slow?

    That sounds horrible. There are a number of reasons it could occur.
    The first thing to do is ensure you have adequate backups, because what you describe can be a symptom of impending disk failure.
    To help determine the possible causes of this behaviour read the following. None of what follows is intended to fix anything, but it will provide the additional information required to advance troubleshooting. There are four separate parts to it; read everything first.
    Boot OS X Recovery by holding ⌘ and r (two fingers) while you start your Mac. At the Mac OS X Utilities screen, select Disk Utility. Select your startup volume (usually named "Macintosh HD") and click the Repair Disk button. Describe any errors it reports in red. If Disk Utility reports "The volume Macintosh HD appears to be OK" in green then you can be reasonably (though not completely) assured your hard disk is in good working order.
    When it finishes restart your Mac and test again for operation. If it's still not behaving as you expect it should, please post the results of EtreCheck in accordance with the following instructions:
    Apple Support Communities contributor etresoft wrote a very useful app to quickly gather certain system information that may help point to a cause of this problem. Read about it here. It contains a link to download EtreCheck. Don't download it from anywhere else (such as may be found by following the results of an Internet search).
    Click Open - etresoft contributes to this forum frequently and can be considered a trustworthy developer.
    It will take a moment to run as it collects its data.
    Copy and paste its output in a reply.
    Do not be concerned about anything that says "Problem" or “failed” or anything else that may appear in red.
    EtreCheck was designed to remove any personal information (such as your computer's name and serial numbers) but if you see anything that looks like an email address or any other personal information that should not be divulged to others, please delete or obscure that information when you post the reply.
    When you are finished with EtreCheck, quit the program. It occupies very little space, and you can keep it or drag it to the Trash as you wish.
    After completing the above please determine if the problems also occur in "Safe Mode":
    Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
    You must disable FileVault before you can start your Mac in Safe Mode.
    Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
    Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
    To end Safe Mode restart your Mac normally. Shutdown will take longer as well.
    System performance problems for reasons that cannot be isolated to any other cause justify an SMC reset. Be sure to read the procedure carefully and follow all the steps exactly as written, even if they seem inapplicable or trivial.

  • My Windows XP computer becomes extremely slow when I try using iTunes. It cannot connect to iTunes Store. I tried uninstalling and reinstalling iTunes but nothing changes. I cannot use iTunes or sync my iPod anymore. Please help.

    I cannot use iTunes anymore. My computer becomes extremely slow or just freezes. I notice the problem started after I updated iTunes to a new version. I have tried uninstalling iTunes completely from my computer and installing it back, but problem continues. We iTunes launches, it tries to connect to iTunes store, but it doesn't seem to be able to do that either. I can't sync my iPod or play back my music, please help.

    With those symptoms, I'd try the following document:
    Apple software on Windows: May see performance issues and blank iTunes Store
    (If there's a SpeedBit LSP showing up in Autoruns, it's usually best to just uninstall your SpeedBit Video Accelerator.)
