My 27 "IMac just started running slow and has a hard time, opening of Yahoo and other sites

My IMac 27 "just started running slow and is struggling to open Yahoo and a few other Web sites. I bought it last August, but he has only started to slow market over the last two weeks. I have reset the pram, restarted with Cmd - R. I restarted in safe mode and as a guest and it still runs slowly. I have used Etrecheck, the only suspect think I wonder on "3.10 GB com.apple.WebKit.WebContent (5). What is webkit?

last week I installed 2 Apple airpot extreme and hard wired two airports and my mac, my wifi I and the entire system is running 5, speed, download upload, and ping 11ms. 8mbps 5.9mbps I uninstalled Silverlight, Lightroom and most of the apps I use, but I can't figure out the problem.  Any ideas on what I can do to get my mac back to the current? I'm about to take my mac at the Apple store because she is still under warranty.

Kind regards

Rick

    Hello, I just upgraded to Photoshop using cloud creative and now when I click on open it crashes just does not reach the start window.

The cost of my monthly subscription increased right here in Australia and I'm facing these questions a lot is that they tested these products before releasing?

  • Running slow and other topics

    Hi all

    I'm looking for some advice on my iMac.

    I bought a 27 "iMac, with the hybrid drive system, 4 GB of NVIDIA GeForce GTX 780 M, 24 GB Ram, 3.5 Ghz i7.  I've had this for about 2 years now, and it is running El Capitan

    For the most part, I love this thing!  However, I had weird problems, and I don't know what to do.

    1. it works TERRIFICALLY FCPX.  That's mostly what I got it for and when exporting and rendering is fast... the interface is slooooooooow MOVE.  For example, I could switch to the razor blade tool, and just have the tools will result in a 2 minutes beach ball (does not whenever... randomly).  This has been the case since the day 1

    2. After awhile, my favorite items are disappearing boxes of import/export.  The shortcut of docs, desktop, downloads, etc... all vanished, leaving only hard drives as options for opening or recording

    3 safari does CRAZY things.  The tabs that I "pin" to the left... all of a sudden stoppage of work... but if I open a new tab and load the page manually, it is fine.  I also get weird freezes, where suddenly I can't scroll or enter nothing... everything just command-tabbing to another program and back which correct... but it happens a LOT.

    4. I also get random "you have run out of memory" messages.  My old iMac i7 must NEVER gave me this message

    5. I get random "gel total ups ' and resets.  I left the room for long periods, only to come back on a machine that completely re-bootred by itself.

    ' 6. I can not disable the Magic Mouse ' slide 1 finger!  When I try, it stays right on!  Not a huge deal, but I ALWAYS accidentally seem to slide backwards while web browsing... even if I do nothing, I moved my finger

    For all this contrast, I recently got a MacBook (the new really thin one), and although it is much less powered, seems to run the operating system faster and without any of the above questions.

    Yes, is there a way to understand what is happening?... or maybe a way to reset the computer (preferably without losing all my data)?

    Ideas, help or similar questions from others would be useful!

  • Satellite M30 slow start, running slow & on most of the time HARD disk activity led

    The question above with my laptop. It is used to run faster than my desktop, but has altered performance. Running XP SP2 and Norton Internet Security and Norton System Works. No error shows when executing the Tests of Norton. Have reformatted the hard drive and reinstalled software but little difference.

    Laptop takes @5 minutes to start. Open Outlook takes 10 seconds. Drive light is on most of the time so I was wondering if the hard drive related.

    Any ideas?
    Thank you very much.

    Try the freeware like HD Tune or HDD Health programs.

  • Help! I ran CCleaner a week ago and now cannot get on a few gaming sites. At the suggestion of a friend I click Start, run, cmd and ping sites and they have not been found.

    Maybe the registry files?

    CCleaner is an excellent program for computer maintenance, but you should never use its registry tools. Because you forgot to tell us which games sites, you can reach, I can't check out them for you.

    If you have used the registry cleaner in CCleaner, see if it has an undo feature and if it does - use it. If not, post back with the URLS of the sites that you can reach. Also tell us what browser you use - IE6, IE7, IE8, Firefox, Safari, etc., and if you do not to sites with a particular browser, what happens when you try with another.

    There was several abnormal stoppages in the last days. A negative stop code may indicate a hardware problem. The precise meaning of the codes is not publicly documented.

    If you haven't already done so, you can try to reset the system management controller. Otherwise, or if the reset has no effect, see below.

    Do a 'genius' one appointment at an Apple Store, or select another authorized service provider. You may need to leave the machine there for several days.

    Back up the data on the internal disks before you turn on your computer to anyone. There are ways to back up a computer that is not fully functional - ask if you need advice.

    If privacy is a concern, delete the partitions of data with the ability to write zeros * (do it only if you have at least two backups complete, independent, and you know how to restore on a blank disc from any one of them.) Do not delete the recovery partition, if it is present.

    Keep your confidential data safe during the repair of the equipment

    Apple recommends that you remove permission to a device in the iTunes store before serving.

  • Several processes that are running on the standard user account because it runs slow and internet does not "."

    Create a user profile for children on PC 32-bit W7 with MS Family Safety.

    Recently they have complained he "runs slow and internet does not work.

    After playing for a little, I realized a ton of processes were running in the background. I couldn't run msconfig to their profile (not administrator) and after some research, I even if the profile has been corrupted.

    I created a new profile, but now the same thing is happening a few days later.

    See below; multiple copies of the same process are running. This happens within 2 m after the log-in and I only started one program.

    I started in safe mode with network and ran Windows defender, Spybot S & D and my virus scanner (all full scans) and turned up nothing malicious.  A few cookies tracking in the web cache, but nothing out of the ordinary.  I searched for the files wlaacmgr.exe and dplaysvr.exe (b/c they do not appear running in my admin profile) but they were found only in windows OS directories.  I understand that they are files of W7 but some maleware recreates.

    Many of them are the same files taking up process on the old profile that I deleted.

    Any help or suggestion as to why I have multiple copies of large processes running on the machine?  As I wrote it, I sign in, seems to be fine for one but 2 minutes a lot of process appear repeatedly and slows down the computer to a crawl.

    These two files listed are not at all on my admin profile and the machine works fine in my admin profile.  Even with open Photoshop, the CPU is only about 50% under my profile.

    Try to check/change the entries in startup with Autoruns from Sysinternals, which should work on the limited account to see its startup items.

  • After the upgrade to the new version of firefox 13.01 I can't play video on youtube and other sites what should I do?

    After the upgrade to the latest version 13.0.1

    I can't open videos from youtube and other sites

    I tried all the solutions, but none works

    I would also consider the following. Recent crashes of some multimedia content (this includes the Youtube videos, some flash games and other applications), in collaboration with Firefox 13 are probably caused by a recent update of Flash 11.3 and/or Real Player browser plugin to malfunction.

    To resolve this problem, follow the steps in these articles in the Knowledge Base:

    Flash Plugin - maintain and troubleshoot

    Adobe Flash plugin has crashed - avoid that it happen

  • Base HP EliteBook 8760w model: computer suddenly starts running slow

    I was playing a game when the FPS started becomes weak, and it is gradually degraded over time. I suddenly realized that my power cord was not connected to the computer, and he was running low on battery so I charged it. After loading, nothing has changed, my browser was slow, staggered games, youtube videos would be in audio delay, then speed up again, just acted really bad. The CPU usage was always about 100% and before all this, my computer has been perfectly fine, extremely fast and usually I would get 144 fps in the game, but now I get 2-12. I tried malwarebytes, safe mode, clean boot, reboot, let it rest overnight, with ca running but no battery, using optimized bios by default, ccleaner clean and ccleaner registry clean.

    I never encountered this problem before, is it a virus or did I burn/break something?

    @Regrettings

    Welcome to the Community Forum of HP.

    A few ideas

    Try a Hard Reset / forced:

    =================================================

    Hard Reset / forced

    • Close running of programs, the browsers and games

    Next

    If you use a laptop

    • Close all your programs and shut down your computer
    • Unplug everything (little unifying for the keyboard / mouse external can stay)
    • Perform the forced reset for your laptop model
    • Start the computer and connect

    OTHERWISE, if you are using a desktop computer

    • Close all your programs and shut down your computer
    • Disconnect devices USB, speakers, other drives useless
    • Unplug the computer thirty seconds
    • Connect the power supply (plug in)
    • Reconnect the devices
    • Start / start the computer and log in

    Reminder: forced reset is a device reset.  The procedure do not destroy your files, or it destroys your Windows installation somehow.  Forced Reset "forces the system to erase and restore the software connections between the BIOS and hardware."

    =================================================

    More...

    • Try to reinstall your game.
    • Take a look at the overall performance from the point of view that the computer is probably not infected - it might be, but maybe it's a coincidence based on timing rather that on a computer running on battery - consider that the system may like to have low maintenance.

    Improving the performance of the system without adding memory (Windows 7)

    • Given the system beating on concern one of the programs that ordinarily would behave himself.  Take a look at the resource monitor - check what is running, how much resources each program uses, and whether these programs that are running are include as expected (not running Amok and steal all the resources).

    Hello

    Case fans will always run so how (speed) is the question.

    Your PC can be covered by the warranty.  Did you check the warranty status?

    Open the PC and use a can of compressed air to blow out all the dust, including the dust of the heatsink from the CPU.  While the PC is open, disconnect and reconnect the connector to the case fan goes to the motherboard to make sure the connection is tight.

    Ensure that the PC to not locked up in restricted airspace.
