Why is my brand new 16 GB, i7 21 "iMac so so slow?

I recently bought an iMac 21 "with the following specifications.

21.5 "iMac 4K 2015 retina

Intel Core i7 3.3GHz

16 GB 1867 MHz DDR3

Intel Pro Iris Graphics 6200 1536 MB

Since the first day it worked remarkably slow. Even during the opening of things such as the finder and system preferences.

I currently own a macbook pro so that works 5 times faster than my iMac.

You have any suggestions of why this could be?

Thanks in advance

Where did you bought it leave?

Have you registered.   (It is covered by a guarantee of 12 months).

You have an Apple store nearby?

  • HP Pavilion 17 Laptop Touch t: brand new out of the box HP Pavilion 17 t Touch M7H91AV laptop is so slow

    Last night, I took my laptop HP Pavilion 17 t Touch brand new out of the box and it is so slow.  The startup is slow.  All operations running slow.  The use of the internet is slow.  I tried to transfer files from Carbonite on this new computer and just the process of realization of this installation took me a half hour.  This morning I had to reboot and it took 5 minutes.  I only know enough about computers to be dangerous, so I don't mess with many settings myself.  This performance unacceptible on a new computer.  This is certainly the slowest computer I've ever owned.  All solutions that anyone can offer (as a reminder, I need instructions step by step)

    Hello;

    Let me welcome you on the HP forums!

    I read your post about serious problems with your HP PC brand new and wanted to help.

    Since it is a machine relatively new, instead of hurt for hours to fix yourself, why not just let HP fix it - for free!

    You must contact the HP Customer Support directly so they put you in contact with HP Tech Support to see what they can do on the diagnosis and repair of your machine remotely.

    I did recently, and HP technology was able to remotely access my PC on the Internet and to make the necessary repairs.

    If you live in the United States or the Canada, details are on this page: http://www8.hp.com/us/en/contact-hp/phone-assist.html#section1

    If you live elsewhere, contact details are on this page: http://www8.hp.com/us/en/contact-hp/ww-contact-us.html

    NOTE: once you get through, stay on the line until you are finally able to talk to someone ' one - it can take a while!

    Good luck

  • Brand new Lenovo Ideacentre Y700 not connect to a monitor

    Yesterday, I received the Lenovo Ideacentre Y700 but when I went to put in place, I found that no matter how I plugged the monitor, the monitor showed an error no signal. All the cables (HDMI and VGA) were brand-new and monitor. I've tried literally all of the ports on the thing. So, I don't know why it does not work. Can anyone help?

    Thanks for the reply, but I went to the store I bought it from today, they have latched on to one of them and it did not work while they exchanged it.

  • AccelerometerSt.exe error on the computer Windows 10 brand new

    I have the same problem that many others have with the Application AccelerometerSt.exe error.   BUT, I have a brand new - 1 week old computer and it came with 10 windows already on it.  I have the HP Envy x 360.   How do you intend that to solve the problem.   If you uninstall and reinstall Windows 10, I'll need much more detailed information.   I don't know how to do this - which was the reason why I only watched computers with her already preinstalled.

    Hello

    Try the following.

    Open windows control panel, open programs and features, make a right click the entry for HP 3D DriveGuard and select uninstall.

    When this has completed, restart the laptop.

    When windows has reloaded, download and install the version of DriveGuard on the following link.

  • HP Envy 15 t-as000: brand new HP Envy w / SSD: "Boot Device not found".

    Hello

    I have a brand new (less than 1 week) HP Envy 15 t-as000 w / a 256 GB SSD.  After the impeccable behavior for 1 week, the laptop can be started is no longer.  No boot device is detected.  If I try to run a diagnostic on the hard disk, the BIOS I was informed that it can not detect even a current hard drive (see image)

    I don't know what happened.  I'm very careful with my machines.  He has not been abandoned. It has not been dropped on, or taken any sort of somehow.  I just pressed the power button one day (yesterday) and I see this:

    Thanks for the tips. I followed your recommendations and sent the laptop to HP for replacement (I bought this unit directly to the output from the HP website).

    However, I am frustrated because after all taxes and transportation costs, I had to pay an additional amount of $10.  The total general of the replacement order was $739,79 against $730,90 for the original purchase.  Why am I penalized $ 10 ($8,89 to be exact) for a mistake that was not even my fault?

    Also, I had to pay $24,83 FedEx packaging to send the laptop back.  How was I supposed to know I should have brought the Moose with me to Seattle, WA in Ithaca, NY packaging because the SSD was going to fail in my college dorm?

    So in the end, my HP Envy $730,90 now goes to the identical replacement of cost unit $739,79 + packaging from FedEx $24,83 phone = $ 764,62.

    Bottom line: screw - up HP cost me $33,72!  Not the end of the world but still a ringing sound nice when you're not yet a career with a cushy salary of mickael elite.

  • Brand new computer is Super slow facilities issues

    I just bought a computer brand new over the weekend.  I decided to buy HP model: h8-1214.  While the configuration of the computer, I noticed that when it comes to install the programs, the installation process takes forever and I just cant seem to be able to install them.  For example, my Adobe programs.  The computer gives me a very long estimate time.  I tried to leave overnight to install, but the minutes about just get more 100 000.   I tried several times and try other programs, but the time to just estimate accumulates.  I tried to download on my laptop computer and another computer and I have no problem, everything is installed perfectly.  I don't understand why this computer is not take quick installation, like the others.  The windows program and the operating system is the same, so I don't really understand.  I made sure that all updates have been made and still no luck.  Any advice would be appreciated.

    Characteristics of the computer:

    Model: h8-1214

    Windows 7

    64-bit operating system

    Problem solved. I just waited a few days to try again and repeat the steps for Sami, check the updates, disabled firewall and tried to install again. This time, I had no problem.

  • MASTERED OPTION IS GRAYED OUT WHEN YOU TRY TO BURN A HOME PC PREM BRAND NEW VIRGIN DVD + R ON VISTA 32-BIT

    Due to virus I had to rebuild PC using the RECOVERY partition on hard drive. All windows updates have been applied to date (August 2011). Before the virus problem (July 2011) WAS able TO SELECT THE "MASTERED" OPTION WHEN YOU are GOING to USE WINDOWS TO BURN a VIRGIN DVD + r. NEW once AGAIN, this WORKED BEFORE, NOW THE MASTER OPTION IS GRAYED OUT.  I have a brand new DVD + R blank and tried several of them thinking it was the disk (I've used this same brand (magnavox) DVD + R 4 years now never this problem of the "controlled" option is grayed out.) I use the same DVD burner which came with the PC and it allowed me to select the option "Mastered" last month (July 2011). I am using Windows HomePrem 32-bit OS (originial system that came with PC and this allowed me to select the mastered option last month. I applied all the updates Win at present. I have no other problems with the PC. Once again, driving the nail: this WORKED BEFORE, last month on the exact same hardware and the software/OS (Juillet2011), then why this option appears GRAYED out now?  This question has been asked before and 'experts' simply stressed totally USELESS MS pages showing how to select either under control or direct - I DO NOT NEED THIS HELP as I ALREADY KNOW HOW TO SELECT either option and what each is for. Also the other 'fixed' DOES NOT APPLY to this situation. (Do NOT send me to the following links because they DO NOT ANSWER to THE QUESTION: http://answers.microsoft.com/en-us/windows/forum/windows_vista-hardware/burn-a-disk-mastered-is-unavailable-grayed-out/9eb41f09-1778-e011-8dfc-68b599b31bf5?page=1&tm=1312314316719#footer or http://answers.microsoft.com/en-us/windows/forum/windows_vista-sound/mastered-format-option-grayed-out/aee1469f-1095-436c-9f12-acce80c2bb99.) These 2 links DO NOT ANSWER THE QUESTION, so answer the question, do not send us in circles, always looking for the answer.  How SIMPLY THE QUESTION IS: Fix us the radio button for 'Mastered' so that it is NO LONGER GRAYED OUT when you insert a brand new, clean the DVD + R in my DVD burner (same that I had for years, which worked before) on my Vista 32 bit OS HomePRem? I have a host of (222 blank GB) of disk space and a lot of RAM (4 GB) and again I WAS able TO select the "mastered"option before my restoration." Help!

  • Brand new Windows 7 system: battery plugged in, not supported

    I just got a brand new Acer Aspire 5542-1462 with Windows 7 Home Premium pre-installed. I have almost exclusively while plugged operated. Battery in the notification area icon indicates that the battery is at "97% (plugged in, does not support)." How can I get the battery charge? Is there a threshold above which it does not load? Some features of the system if they will help you:

    AMD Athlon II X 2 M300 2.0 GHz
    4 GB OF RAM
    ATI Radeon HD 4200 graphics card
    battery Li-ion 6 cells

    My power profile is balanced with the only change so that everything always remains that plugged while. This is my first Windows 7 machine after years with XP, so I am new to the operating system. I searched around the internet and here and can't find anything.

    Hey,.

    This is how it works:

    1. When you turn on your laptop, if your battery is more than 95%. you will get the message "connected but no charging current.

    2. When you turn on your laptop, if your battery is less than 95%, you will see the message "blocked and charge" until the battery reaches 100% (not 95%). That is why sometimes, even if you see that your battery is at 97% and load, this means before starting your laptop, the battery was less than 95% and reached 97% since then.

    Apart from the above explanation it seems some problems with the mentioned error. So, try the following steps as well.

    1. click on Start and type device in the search for field, and then select Device Manager .
    2 expand the category of batteries .
    3. under the batteries category, right-click in the list of Microsoft ACPI compatible with battery control method and choose Uninstall .
    WARNING : do not remove the Microsoft AC adapter driver or any other compatible ACPI driver.
    4. on the taskbar of the Device Manager, click on Search the hardware changes .
    You can also select Action > search the hardware changes .

    Give that a try!

    Hi John,

    We have several audits of bug:

    ATTEMPTED_EXECUTE_OF_NOEXECUTE_MEMORY (CF)

    This indicates that an attempt was made to execute non-executable memory.

    KMODE_EXCEPTION_NOT_HANDLED (1e)

    This indicates that a kernel-mode program generated an exception which did not catch the error handler.

    Verification of error 1E, {ffffffffc000001d, fffff801af0bb63e, fffff801af363800, 2}

    0: kd > fffff801af0bb63e ln
    (fffff801'af0bb600)   nt! KeReleaseInStackQueuedSpinLock + 0x3e |  (fffff801'af0bb670) nt! KeResetEvent

    ^^ The exception is produced in nt! KeReleaseInStackQueuedSpinLock. This routine restores the original IRQL that the operating system saved at the beginning of the call to KeAcquireInStackQueuedSpinLock .

    KeAcquireInStackQueuedSpinLock increases the level of IRQL at DISPATCH_LEVEL level during the acquisition of the spin lock.

    If we check the IRQL at time of accident:

    0: kd >! IRQL
    Debugger saved IRQL for processor 0 x 0-2 (DISPATCH_LEVEL)

    ^^ Very well, we're right on the money in the measure of the level IRQL go... but why an exception occurred here on this pretty normal routine? My guess is we had a DPC/lock and the system deadlocked. It could be both material.

    TIMER_OR_DPC_INVALID (c7)

    This is issued when a timer kernel or deferred procedure call (DPC) is located somewhere in memory where it is not allowed.

    This problem is usually caused by a driver, not to cancel a timer or a DPC before freeing the memory where he resides.

    ---------------------

    1. make sure you have the latest video card drivers. If you are already on the latest graphics card drivers, uninstall and install a version or a few versions behind the last to make sure this isn't a last number one driver. If you have already experienced with the driver of the card later and earlier versions, please try the driver beta for your card.

    2. remove and replace McAfee integrated Windows Defender in Windows 8 for temporary troubleshooting purposes as it is probably cause conflicts:

    Removal of McAfee- http://service.McAfee.com/FAQDocument.aspx?ID=TS101331

    Windows Defender (how put on after the withdrawal)- http://www.eightforums.com/tutorials/21962-Windows-Defender-turn-off-Windows-8-a.html

    3 if the two above fail, return the laptop ASAP for a new replacement brand as then it is a hardware problem. No brand new laptop should be planted in all circumstances.

    Kind regards

  • Brand new Photosmart C410A duplexer jams to each double-sided printing

    I got a brand new HP Photosmart Premium Fax e-All-in-One Printer-C410a Monday. Today is Wednesday, and I have yet to print a two-sided copy successfully. It will print the first side of a page, pull the paper in the duplex unit, display clear paper jam then press O message, and I'll open the duplexer and remove the paper

    Recto pages seem to print very well, but this product every time I try to print double-sided copies - the duplexer has not worked once.

    The jammed paper that I am deleting is not torn or badly crumpled, and since he's out of the box for three days now, I can't believe he would already need cleaning. Is there something obvious that I'm missing, or do I just to cart this thing at the store?

    (It doesn't seem to be relevant to this problem, but the printer connected via USB to an iMac running the latest update of Lion. I upgraded to good Lion before purchasing this printer, so the only drivers I have are the ones downloaded via Apple Software Update.)

    Follow the instructions in cleaning here:

    http://support.HP.com/us-en/document/c02110413

    seems to have solved my problem, at least for now. I'm not clear on why a brand new printer, charge-out-of-the-box if need cleaning to work properly, but if that's all it took, at least, it's a good solution cheap and fairly easy.

  • I have an old Mac Mini with a DVI Port that came with a VGA DVI-adapter.  Tonight, my monitor went down.  Brand new monitor works with that?  Can I use an adapter?  If yes should which adapter I?

    I have an old Mac Mini with a DVI Port that came with a VGA DVI-adapter.  Tonight, my monitor went down.  Brand new monitor works with that? Any recommendations? Can I use an adapter?  If yes should which adapter I?

    You can use any DVI monitor DVI port directly or have any VGA monitor with the power that you adapter. A HDMI monitor might work with an adapter DVI to HDMI in a pinch, but HDMI tends to be more fickle.

    How can I get my serial number or IEMI number for me to make an appointment at a genius bar or get help online when my iPhone brand new completely deserted?

    The IMEI number is printed on the back of the phone, unless it's an iPhone 6. You can also find the serial number by eject the tray of the SIM card on the right side of the phone (insert a paper clip or similar object into the hole). It is in very small print at the bottom of the status bar.

    It should also be in the box the iPhone provided in if you bought Apple or an authorized dealer.

    -do a soft-reset/reboot of the iPad ("force restart" on this page: restart your iPhone, iPad or iPod touch - Apple Support)

    If they don't fix it you tried:

    iMovie and iLife and iworks Apps are free with the purchase of a new device.

    Since Apple is no longer selling the iPhone 5 s, she cannot be considered more for free apps.

    However, just to be safe, disconnect you from the iTunes and App Stores-> Apple ID in the settings on the new iPhone 5 s, then reset the iPhone in now the home and power buttons together for 10 to 15 seconds. Let the iPhone reboot and then sign in with your Apple ID in iTunes and the App Store and try to get the Apps again.
