After a fan failure, Windows is unable to turn off the fan?

My Dell laptop is more than a year and out of warranty, so I was pretty shocked when my brother took an air can to the exhaust port and overspun fan and caused his failure. I bought a fan of alternative qualified from Dell and installed with Arctic Silver costs. However, even with the new fan, he would never turn up. I was looking at the temperatures to pull it up and and eventually shut down the system without even a glance of the fan. I even pulled the fan back out and double checked to make sure that the fan would turn with the applied force (I am an EE, food is very fine-adjustable). He does.

I can control the fan with a 3rd party, i8kfan program. Problem is, the driver is not signed digitally, so it occasionally fails or it shuts down randomly.

So, how does this apply to Windows? Well, as Dell technical support doesn't help if you are no longer under warranty, they don't tell me this - here are the fan control strictly controlled windows, strictly the BIOS or a combination of both? I was wondering if the problem threw a flag in Windows or the BIOS can't disable or something. I see nothing on the fans in my BIOS (another failure on part Dells - shitty BIOS), so I hope there is something small, buried in the windows that might help.

I have no problem using the 3rd party controls. In most cases, this works very well. But there are moments when, particularly under heavy load, the program gets a lower priority, and fan just stops. In addition, the signed drivers beyond boring thing. As a little advanced Windows user, I'd love it if it could be disabled permanently instead of having to switch off whenever I start.

My college got hooked me with a copy of 7, but I was saving it for my office that I'm building. I think that if this is a Windows problem, I'll just reformat this thing at 7 until I get my desktop built, and if all goes well, that will fix problems with fan. Also, I think I still have the Vista disc to this thing also, that's an option. If reinstalling Windows can solve this problem, I will def do this. I don't want to waste time to reformat if it does not solve the problem.

Thanks for the comments!

Hi Matt k,

Fear you must contact Dell technical support as seems to be a hardware problem.

  • Unable to turn off the Magnifier in Win7

    original title: I made every effort using all the instructions I can find to turn off the Magnifier in Win7 and none of them worked.

    I'm unable to turn off the Magnifier in Win7 and asked help available to all sources known to me. I was told to use the ease of access and uncheck Mgnifier.

    Because it did not work.
    Then I tried to use settings in the mouse - did not work.  And there are other approaches - none worked!
    I guess the Magnifier is useful for some, but for me, it's a major nuisance and I would definitely find an approach that would disable it permanently...
    E-mail address is removed from the privacy *.

    I'm curious now. Do you want to say its always active and cannot be turned off, or it appears now and again when you don't want or need?

    Maybe these posts can help?

    original title: don't stop after update

    (1) never install two security systems on the same computer because of the possibility of conflicts like this.  Norton may have similar tools to what you were trying to install.

    During the validation of the subjects as that one, don't forget to post your operating system of Windows and the computer make and model.

    Recovery discs are here with your system?  Alternatively, did you create recovery discs?  Have you created a boot disk?

    (2) by changing the boot order, you can force your computer to boot from a CD/DVD drive, a floppy, or even out of the network drive.  Use the startup disk or recovery disk if you have one.

    If the answer is still no, you need to get the site of the manufacturer of the computer recovery discs. I think that you will be able to order Windows Vista or Windows 7 but Windows XP is rained on many sites and an internet search may be more useful in this case.

  • Unable to turn off the computer, it will restart every time in Windows Vista.

    Original title: portable computer complete crash

    I am running Windows Vista Home Premium on HP Pavilion DV2208e.
    A week using Adobe Photoshop Lightroom, the screen went black and all the lights on the laptop has continued. I tried to stop the laptop by pressing the power button, but it did not work. The only way to stop the laptop was to unplug the power cord. The next morning, that I started it again, with a notice "Windows did not close properly, how you want to proceed.» I opted for "start Windows normally". It seems to work very well, with the expection that the date had re-fixed at the date where Vista was installed first of all a few years ago. Later, when I tried to stop the laptop by choosing from the menu start 'Shut down', the laptop shuts down normally, but then 2-3 seconds more later handed on himself. I tried several times and it's always the same, the way to stop it is by pressing the power button, then whenever it restarts it new note that Windows not stop correctly. Also the black screen crash turned up almost every two days.

    I tried reinstalling antivirus and did a full scan. Also used ccleaner and décliqués "Automatically restart" in the advanced system settings. But nothing seems to have worked so far.

    In computer management, I can see critical events that seem to correspond to the time when the black screen error occurred. They say the following:
    The last sleep transition was unsuccessful. This error can be caused if the system unresponsive, failed, or loss of power during the transition from sleep

  • Unable to turn off the built-in in Windows 7 Home Premium Administrator account

    I can't disable the built-in Windows 7 Administrator account. I tried to do it via a command prompt with "net user administrator / active: No. ' but all this, after the reboot, is display an error message about the incorrect user name or password and presents the administrator account as an option to login anyway (with an option for"other users"). But if I try to connect to the administrator account a password for log-in, which I did not.
    If I activate the account (again in elevated command prompt), I can connect as administrator normally, without password.
    I can always connect to my own account without worrying, but I would like to know how to solve this problem in any case. Can I avoid the error by removing the password from my account, but I don't want to do that.

    I created a test account Admin attempt to connect to it gives this error:

    "The service user profile Service has no logon.
    User profile cannot be loaded. »

    Ah, the dreaded problem of profile Service. I've seen dozens of times in this forum, but I have no solution for it. If you do a search on Google you will find countless references to it. I invite you to solve this problem first, before you disable administrator accounts.

  • Default configuration restoration changes Windows updates do not turn off the computer

    Step 1 of the 'solution' to this error reads:

    Drag from the upper right of the screen (or if you use a mouse, move the mouse to the upper right of the screen) and then tap or click settings.

    It is impossible to do this step 1 because my computer never stops display failure message to offer a mouse or interactivity, whether... it is in an infinite loop of failure with no way to stop.  Same way as fail-safe after power reset does not work.  There is nothing I can do at all.

    You will then need to repair your computer using a recovery disc or installation media.

    Boot from the media(Instructions are here)

    and then select repair your computer in the first screen that says install now:

    Then follow option 7:

    I recently updated Windows XP and inadvertently acquired auto-snap windows. How this feature can be disabled?

    It can be a good step and should certainly fix this, assuming it was an update or a registry change that caused it) if it is a 3rd party program can continue to be on the system as a repair installation does not interfere with currently installed programs.

  • Unable to turn off the camera RAW JPEGS to destroy,

    I have CS3.

    Some ONLY open with Camera Raw in PS jpeg files, no matter what I do. I just want to open regularly, but I can't get go in ACR and ACR is corrupt somehow the color when it opens them this way.

    In preferences, I have disabled "prefer camera raw" for jpeg (in PS and bridge), but it does not always help.

    The problem is that the color gets ruined when open with ACR, any color space, I choose within ACR during development, the files get a washed appearance and once opened this way can be repaired through normal methods, ala "convert to" or "assign" the right color profile.

    Note that other jpegs do not open with ACR before seem fine and unaffected, they do not open via ACR in PS, they just normally open in PS, and I see the expected "color profile mismatch", if any.

    Also note that files that are themselves ruined by ACR look OK in Bridge and in the preview itself, but once open in PS ACR window, they are totally different.

    Is someone can you please tell me how I can stop ACR to ruin their or just deactivate ACR for good? Thank you. The files are essentially unopenable as they are right now, and I don't see any 'clear' options settings that future versions of PS seem to have development.

    Thank you!

    You uncheck the box for jpeg within the acr dialog box?

  • Unable to turn off the read-only

    I tried to turn off the read-only on a folder in my Program Files (x 86) folder so I can edit a file for a game.  I tried everything I can find on the internet without success.  Here's what I did until now (I'm on an administrator with maximum permissions account):

    1. I tried to uncheck the read-only box.  Whenever I close the properties and reopen, it is checked again.

    2. I tried to run the attrib - r + s function cmd as admin, but nothing has changed

    3. I ran a chkdsk, still nothing

    4 changed property in the security properties, as well as assuring you of my account has full permissions with all of the Program Files (x 86) folder. I then tried again the first 2 steps, is always checked.

    Anything else I can try?

    What you need to do is Notepad opened by right-clicking on the Notepad icon and then selecting run as administrator.

    Then, while in Notepad, open the .ini file.

    Change it and then you will be able to save him.
