strong volume after starting the system activity

There is an activity volume on three different computers (iMac 27 "3.2 GHz MacBook Pro 15" 2.8 GHz mid 2009 at the end of 2012 and MacBook 13 "2.26 GHz late 2009) once the system has started. It's worse on the iMac that is the most powerful of the three computers. Less than 10 minutes after startup, the computer reads more than 5 GB of data and written more than 2.5 GB of data (reported by activity monitor). The replies from the computer very slowly. The Finder displays the content of windows after 30 seconds or more. Programs need more than two minutes to start. After about 7 to 10 minutes the heavy disk activity subsides, and the computer is fast.

In the activity monitor, I can see that Spotlight and its mds workers uses a lot of CPU power and drive. They index for about 5 minutes (the progress bar appears in the Spotlight search window). I've already wiped the Spotlight index and rebuilt twice. It does not help. There is no startup item that could break the computers. Why does the system read in so much data? What is it? Is it possible to postpone the reindexing of Spotlight on the system startup? Please do advice generate me SSD to three computers.

  • Error message "the computer restarted unexpectedly or encountered an unexpected error" after starting the system on Windows 7 Recovery.

    While trying to reinstall Windows 7 on my Dell Inspiron 1545 of the reinstall DVD after you have installed a hard drive again, I got this message: error message "the computer restarted unexpectedly or encountered an unexpected error" after starting the system on Windows 7 Recovery. Tried F10, SHIFT F10 and nothing happened. Then I tried a suggestion of virtual Agent to press F8 to get to advance Boot Options, but this option does not appear! Help!

    For Dell cptrs, you will need to press F12 to access the unique Boot Order Menu(= a temporary setting), little after the Dell logo appears on the desktop. U hv only 5 seconds to do, b4 the cptr will automatically initialize to top with the internal HARD disk.

    ....... F12 is usually used to start the cptr since the DVD player or a plugged in USB-flash drive with a Win 7 install or recovery media.

    To permanently change the boot order, you must similarly press F2 to access the full Boot configuration Menu. The default boot device is the internal HARD drive, but this can be changed to DVD player, USB, disk, network drive, etc. F2 is usually used to start the cptr of an external hard drive(= USB HDD) that contains a bootable Linux operating system.

    Any help would be appreciated

    Thanx

    Hello

    For me, it looks like a malfunction of the HARD drive and so the BIOS can not find a bootable device and goes to the last possible bootable option which is LAN.

    The exclamation mark in front of the HARD drive indicates that there is a problem with the HARD drive so I think you need to replace the HARD drive and you need to reinstall the system.

    PS: What laptop do you have exactly?

  • Satellite A100-00N - cannot start the system

    There were 15 months and now when I push the power button to start the system, it will not work.

    There are 2 blue LEDs lighting but the computer won start t. tried to release the battery and configure power but not luck, with the battery also no luck. On Toshiba that works is the button located under the power button (globe photo with the left and right arrows and a photo of a music note in a display of television or something) when I press this button you hear system starts but after a second or 3-4.

    Also tried to remove the memory and hard drive but still no luck.
    Anyone?

    Sorry, but there must be a serious problem, and I don't think that there is nothing you can do. The idea to start the laptop with power running is OK, but if this doesn't work and you see nothing on the screen, it must be a serious problem.

    Of course you do not give any information that you did the last days with your laptop. Maybe you tried to update BIOS?

  • Whenever I start the system complains that the following files are missing, c:\\Windows\System32\igfxpers.exe, igftray.exe and hkcmd.exe.

    Original title: files missing error

    Whenever I start the system complains that the following files are missing, c:\\Windows\System32\igfxpers.exe, igftray.exe and hkcmd.exe. Everything started after I ran scan and scan deleted some files infected. However, I can use the system. Where and how to download the missing files? Or how the system does not deliver messages?

    Simon

    Two of the three files are probably part of the malware infection and not the files infected. The third is probably the same details in this link:
    http://www.Runscanner.NET/file/Hkcmd.exe.html

    To identify what loads when you start using Autoruns (freeware from Microsoft).
    http://www.Microsoft.com/technet/sysinternals/ProcessesAndThreads/Autoruns.mspx

    With Autoruns, you can deselect an item which disables startup, or you can click with the right button on an item, then remove it. If you clear the check box that you can check back for re - activate the element. It is an approach much safer than editing the registry and better than using msconfig. You will find the three points and they will have a description 'file is missing' against everyone. Your antivirus software has removed the files, but not the startup entries in the registry. All you need to do is delete the entry using Autoruns to eliminate the error messages.

    Another useful feature of the program is that you can click with the right button on an item and select search online to get information about the selected item.

  • Unable to connect to wireless internet after formatting the system.

    Original title: Mr

    Hi, please my dell Inspiron gives me a serious problem to connect to any wireless router, I can only use moderm to brose, I can't connect to any wireless network, this happened to me after that I have format the system but all other things work.

    Hello

    Thanks for posting your query on Microsoft Community forum.

    As you mentioned after formatting the system, you cannot connect to a wireless router, I recommend updating the firmware on your router and updates your wireless network adapter drivers, as there might be a chance that the wireless drivers are deleted.

    The majority of connection inside Windows 7 problems have been resolved by installing the latest driver for the wireless card with obtained from the manufacturer. Download and install the Windows 7 compatible drivers and check whether the problem is resolved.

    You can refer to the link provided below to update the drivers from the manufacturer's website.

    DELL drivers.

    If the problem persists, I suggest you try the below mentioned methods and see if it helps you to solve the problem.

    Method 1:

    First of all, I suggest you run Windows built-in network troubleshooting to get the problem automatically detected and corrected.

    See the article below to run the network troubleshooter utility.

    Using the troubleshooter from network in Windows 7.

    http://Windows.Microsoft.com/en-us/Windows7/using-the-network-troubleshooter-in-Windows-7#section_2


    Method 2:

    This problem can also be bound to the adapter, reset, update driver, disabling, re-activating, uninstall and reinstall network adapter can help.

    Follow the steps in the following article to troubleshoot network adapter.

    How can I troubleshoot network adapter?

  • AutorunsDisabled window opens when you start the system.

    Whenever I start my computer (Windows XP SP3), a Windows Explorer window appears showing the AutorunsDisabled folder.  Nothing is in the folder.  I installed Windows XP-KB967715 - x 86 - ENU.exe and MicrosoftFixit50471.msi of Fix - It of Microsoft in the hope of preventing the Windows Explorer window to appear whenever I start the computer.  He still appears every time on starting the system or re - start.  Can someone help me with this problem?  Thanks in advance.

    It's probably in your startup folder. Check. Start, all programs, startup. To remove the open disk (c), open Documents and Settings, open all users or the folder with your name (only in one, try all users initially), open a Start Menu, open programs, open start and if it is delete it.

  • Deleted some files in the windows directory a few reasons, after restarting the system. showing a victim of COUNTERFEIT windows. How to reactivate my windows?

    Hi all

    I bought Lenovo laptop 10 months before staple. Today in my system, a malicious program "Progressive Protection system" is automatically installed. As a result, I searched the Internet and deleted some files in windows directory in C drive. Now after restarting the system, it's popping up a message stating "you are a victim of counterfeit windows. Even I have validated my window in internet with options available always is saying that my window is not genuine. Don't know how to turn it back on. If someone can help with this problem?

    I suspect that the problem is that the malware is still present - a repair installation will not get rid of it.

    @Prad_121

    Please follow the directions for the RDO and run the analysis offline so you can - at least, so we can be reasonably sure that the machine is free of malware.

    Once completed, please post a new report MGADiag.
