This design has an area of wind on the lower edge of the carcass from which the internal fan draws in air (cooling).  Visually check this area for dust accumulation that may block the flow of air, which could be the reason for the "heat up".

The line running across the screen may be a hardware problem, if you see immediately after a restart, while the iMac is still putting into service.

  • NB200 - freezing point arbitrary during any installation of OS

    Hello.

    When I just got NB200 out of the box and began to start the first thing that was the case, was hanged on the XP splash screen before any options. After 15 minutes I reset it and it got a few steps in XP installs where it installs programs. then he kept something with furniture of mouse cursor still for > 1 hr, finally I turned he walks and went up in broken XP situation.
    I use combo reset factory of manul (hold 0, start) but it does not then how do I do it factory reset?

    Now, when I try to install Win7 from a point-to-point arbitrary flash drive (sometimes even before showing the first Setup screen on green looping animation of progress, sometimes when filling out the list of partition, sometimes during the "expanding windows files", sometimes all in "installation", after a reboot) it would be to stop doing whatever it is. Cursor of the mouse is mobile and even, no ceases to animation loop, but there is no activity of HD, no fan activity (i.e. no high CPU load?) and if it "freezes" like than to expand our files, USB key will stop blinking what he does when he's actually progress,

    Interesting that for example it has spent 20 minutes on the extraction of 84% of the files once. While during installation when it is the 'end', it extracted the files very quickly, so I guess this isn't a problem at any time and it is just random.

    How can I fix it?
    Should I ship to Toshiba for repair or replacement (I'm going on vacation so unlikely to be able to use the replacement store in time).

    Hello

    On reset to factory settings, you will find all the information in the user manual.
    This means that if it is not possible to use HARD drive recovery option, you will need to use the Toshiba recovery disc but I guess you don't l t s create, is that correct?
    If not and you want to return to factory settings you need to order a new drive of Toshiba Recovery directly:
    https://backupmedia.Toshiba.EU/landing.aspx

    Depending on your problem with Windows 7 I put t know what could be the reason but it's maybe s material hard work because the XP installation didn't complete successfully. So for me it sounds like that it of not a software problem.

    To be honest in your case, I'd go for the authorized service provider nearest. Technicians can check your laptop and determine if it s a hardware or software problem.
    I guess that your laptop is still under warranty, the repair should be free.

    Good luck, buddy! :)

  • EliteBook 840 G2: Elitebook 840 G2 screen freezing Point

    Videos are not, but its is issued, unless you keep the mouse pointer movement (then it will display the video. Web pages also freeze, you can't scroll down unless the mouse pointer is moved. All this tends to happen when running on the battery.

    Not sure if anyone really cares, but the hardware acceleration IE solution helped some, but only on online videos. Videos played directly from the PC as video WMV Windows media player has always had problems with freezing. If anyone is curious, I finally solved the problem by opting for an Aero theme, then back to the original theme. The only thing that I noticed the change is the basic colors Windwos. Who should not have been laid down that way anyway. I already have an aero theme, but the colors were always fundamental. Make this change to solve all the problems. Don't even have to check the acceleration option in IE either.

  • Freezing point of Skype computer

    Recently updated to Skype and now whenever I am in a call/start one, Skype freezes and also freezes my computer. How can I solve this problem?

    You don't have any physical webcam connected to your computer. Virtual Dxtory and XSplitBroadcaster Video Capture applications are likely to conflict with recent versions of Skype. Try disabling these applications.

    Alternative is to disable the video input in Skype by editing the shared.xml file:

  • Freezing point more of SanDisk SSD drive

    I put a 120 GB Sandisk more SSD in my old laptop, and it now has a problem where it spontaneously freezes for a minute and then working again normally. No error appears in the log when this happens. I upgraded to Windows 10 (starting from Windows 7) and it is always the case.  Actually, it happens much more frequently with Windows 10 he did with Windows 7.  I never had this problem with the original HARD, or with a Samsung SSD Evo drive, so I'm pretty sure that Sandisk is the culprit.

    I installed the Sandisk Dashboard, and it shows no problem with the SSD drive.  Firmware is up to date.

    The material is a Compaq C502US computer with processor Core 2 Duo and Intel 945 Express chipset.

    Thanks for solutions or troubleshooting assistance.

    Hi mc510,.

    My first suggestion is to turn HIPM on your PC, power management can sometimes cause symptoms as you described.

    If you still experience this issue, or if you want to know how to disable HIPM, please contact our support center for more information.

  • BlackBerry Smartphones Blackberry 9360 with clock freezing point Curve every few minutes?

    Hiya,

    I have this problem with my BB C 9360. It does this when I have NO background running application except the ubiquitous five - BBM, MSG, calls browser (do not use!, but it is just there still-_-) and home. There is no white behind the clock widget screen, but sometimes, when she disappears a white creen flashes, like, a second and then my BB starts frantically trying to do things, he was invited to before freezing - it's frustrating and I'm worried - it is barely 2 months old!

    I looked through forums and other things and everyone says its cos of the apps but I have 1 single extra application on my bb and I actually removed 2 apps it is came with; PPL say it's because of the memory full, but I only have about 300 songs and 100 photos on a 16 MB Memory Card o___O

    He started last week and gradually started from 1 - 2 times per day for 1-2 times every 5 MINUTES this morning, while I was trying to delete some MSG and using bbm surveys

    HELP I don't know what the problem with it...

    in the browser options = clear the Cache, clear the cache in all the other apps that have a cache, also on the home screen press and hold the ALT key and press LG LG then optiions clear log. should accelerate and stop the gel as well

  • BlackBerry Smartphones freezing point and go slowly - do I just a media card?

    I have new Bold 9790 and if I put more than a few apps on it freezes all the time or I get a clock icon and it takes forever to do anything. I just need to get a support card for more storage or I have a more serious problem?

    Thanks in advance.

    Susan

    Yes, I think you should have a sd card, I'm a little confussed why these 9790's do not come with an sd card. like most Blackberry, you need a memory card for saving all your photos and music on, also clear in the browser, facebook, twitter, bb maps and any other application that has a cache, the cache also on the home screen, hold the ALT key and press options then LG LG clear log, it will make your phone run more fast and more fluid

  • iTunes freezes for 30 minutes

    I know there have been various reports of iTunes to different freezing points, but I have not seen a solution for my particular problem.  I was hoping it will go away (I submitted a bug report, but I have not, nor I, a reply), but it seems that my problem is limited to just me... :))

    Whenever I connect an iOS device (iPhone 6 with iOS 9.2.x iPad 2 Air with iOS 9.2.x even an iPhone 4 with iOS 7 and 9.2.x), iTunes has the rotation for about 30 minutes beach ball.  After that, the device syncs properly.  While iTunes if frozen, however, I am still able to access pictures on the device using Photos or Capture of Image, so the device itself is not frozen.  Can I force quit iTunes apparently without additional problems.  If I can do something that seems to have access to the Internet (for example, achats purchases transfer, updated iOS, etc.), then iTunes will freeze again for about 30 minutes before doing what it is supposed to.  Everything seems to work, it's just this long delay which becomes really annoying.

    I don't remember exactly when it started, but I think it was last year or so.  As I said, I kept thinking it's a unique thing and that he would go with the next update of iTunes, but it didn't.  I tried to reset iTunes preferences, but that did nothing.  A new user and a bookstore empty iTunes caused the problem go away, but it's not really what I wanted to do.  Any suggestions for what I can try?

    When you see a beachball cursor, note the exact time: hour, minute, second.

    These must be run as administrator. If you have only one user account, you are the administrator.

    Run the Console application in one of the following ways:

    ☞ Enter the first letters of his name in a Spotlight search. Select from the results (it should be at the top).

    ☞ In the Finder, select go utilities ▹ of menu bar or press the combination of keys shift-command-U. The application is in the folder that opens.

    ☞ Open LaunchPad and start typing the name.

    The title of the Console window should be all Messages. If it isn't, select

    SYSTEM LOG QUERIES ▹ all Messages

    in the list of logs on the left. If you don't see this list, select

    List of newspapers seen ▹ display

  • Windows freeze/thaw when you surf the web

    Hello world

    I had a problem with my PC for some time now and it is really really annoying me.

    When you browse the web with Chrome or Firefox, it freezes for a few seconds (up to 10 at least) constantly then thaws again. If I watch a YouTube video, the picture often freezes for a few seconds but sound keeps going, then it goes back to normal.

    I can play games in 3D without any freezing point, I can use Office and other applications without any problem, it's just web browsing. I tested Internet Explorer as well, but only for a short period and so far have not been able to replicate.

    Initially, I thought it was a problem with Adobe Flash Player, so I uninstalled, rebooted and reinstalled. No change. I can often be on the pages of plain text with no Flash animation and still freezes when entering the URL or scroll to the bottom of the page. I use the HTML5 in Chrome for YouTube Player, so can not see how it can be Flash Player causing the gel.

    Below are the specs of my PC:

    Bicoeur AMD CPU (3.2 Ghz)

    16 GB of DDR3 memory

    Brand new Samsung Evo 120 GB SSD (my old Corsair died)

    1 x WD 500 GB HDD

    512MB Nvidia GeForce 9600GT (old, I know)

    Card mother Gigabyte, with the latest version of the BIOS

    DVD burner

    500W PSU

    I already re-installed a completely new copy of Windows 8 on my new SSD when the old man died, but the problem persists.

    I tried to unplug the DVD drive and the 500 GB HDD to rule them out, but it made no difference.

    I think out my video card and the transition to the car as a test video, but I don't know if this will help.

    The PC was built by myself about 3 years ago, but I'm a little out of ideas as to what could be the cause of this trouble on my PC at home.

    Anyone else have any suggestions? Could it be faulty memory?

    Looks like I solved this myself.

    When to remove my graphics card and turn on/off the PC, I got 3 beeps and no BIOS screen. I looked in my manual of the motherboard and it says error memory, so I removed and re-sitting all of my RAM.

    Tested the PC with only the embedded video, could not fault, so put my old 9600GT back in and everything works fine.

    Before I did this, I booted up a Linux Live USB distro, and I could reproduce the exact same gel I was getting in Windows, so I knew it must be a hardware problem.

    I'll run memtest86 later and make sure that my memory is not faulty.
