Nv4_disp.dll is aparrently unsigned when it is!

My DxDiag says: display 1 tab: the nv4_disp.dll file no is not digitally signed, which means that it has not been tested by Microsoft Windows Hardware Quality Labs (WHQL).  You may be able to obtain a WHQL logo driver from the hardware manufacturer. But it is signed and it is authentic. How can I get my PC to recognize it?

Someone told me that I had it after looking through my DxDiag, as I asked him to because that Assassin's creed II hangs on the intro to ubisooft all the time and he says its because I don't sign him... but all other games work fine and it is authentic

Hello

Understand that not all files are digitally signed which could include this Nvidia display dll. I suggest you to focuses on the game with the question and not the dll unsigned.

Step 1: I would say that reduce you the hardware acceleration on your computer and check if it helps.

(a) click Start, click run, type desk.cpl, and then click OK.

(b) click on the settings tab and then click Advanced.

(c) in the performance tab or on the Troubleshooting tab, move the Hardware Acceleration all the way to the right ( Full position).

(d) click OKand then click close.

(e) If you are prompted to restart your computer, click Yes.

Step 2: If the previous step fails then I would suggest that you update the graphics card with the latest drivers from the graphics card manufacturer's website.

    When I put a load on the graphics card, it crashes randomly with this error, on what even the power button does not respond. The leels of heat are fine, CPU History shows that the processors are not maxing out etc. I contacted toshiba and had to format and start over; I did and told me that I must be able to produce the problem with provided packages, such as MS Paint. I don't see how that's possible.

    I do not understand why the answer I got seems totally different response [email protected]_UK obtained his branch of toshiba (they replaced the system board as my only insists that the problem is that the 3d software is 'inconsistent').

    I spoke with a friend at work who suggested trying a 3rd pilot, but that means I need to know the chipset for the geforce go 7300. I don't know how to do this. Can anyone help?

    I bought an extension of 2 years on the warranty of my mobile, but if the local toshiba insists that they investigate not on, I can't really afford a long legal battle and he doesn't seem to be any support from toshiba that can communicate with the technicians who wrote the toshiba card to warn of a possible bug , or who can communicate with the hardware vendors if it's a hardware problem.

    Hello

    Hmmm, I know Toshiba warranty does not cover problems of software 3rd party and it seems that this problem of graphics driver nv4_disp.dll appears only when the graphic card or the driver running at full capacity.

    I read somewhere that the original graphics driver could help, but this is only a suggestion.
    But the problem is that it is not possible to install the original graphics on the laptop driver

    After a deep reflection I ve you know. You may download the original driver of this map on the nVidia site, select the nv4_disp.dll file and replace it with the file placed on the HARD drive.

  • 4 different instances of nv4_disp.dll?

    Hi, since a few weeks I keep getting several messages on blue screen regularly when I end up playing stuff. The most common error message has been about nv4_disp.dll (although I have also recently received an error message about memory management, think about it if you want), so I searched for a solution.

    I seem to be on the path to get there when I found a post here in these forums on a guy with similar problems, except that he had four different instances of nv4_disp.dll. A research of system gave upward the same result as his own, even though I have locations and sizes slightly different files:

    \System32 contains a 6248 KB file,

    \ServicePackFiles\i386 contains a file 4175 KB,

    \SYSTEM32\ReinstallBackups\0008\DriverFiles contains a file of 5917 KB

    and \SYSTEM32\ReinstallBackups\0025\DriverFiles contains a 6195 k file.

    Could someone perhaps explain to me what it is all about offering me a solution? It would be highly appreciated.

    I just did a check on my two memory cards memory, and it turns out that one of them was completely defective. It works fine now without the faulty memory card. : D

  • error message saying a .dll file is missing when I try to acess Mngr.vdmdbg task not found.

    I have uninstalled or deleted my Windows XP Pro VDMDBG.dll because I received error messages after

    I am now using the same IDE on this DIY PC like what I used to have XP Pro running. I ran an upgrade or r disc install to resign the drivers and at the same time you run some programs to uninstall some of the OLD drivers of the motherboard and temporary files, but I must have too deep because now, I have only this error message telling me that a .dll file is missing when I try to acess Mngr.vdmdbg task was not found. Reinstalling the application may fix this problem. Where can I go to download or difficulty this annoyance file or program? Thankx again! -Al

    Sounds messy.

    If you see a message like this:

    Taskmgr.exe - Unable to locate component
    This application has failed to start because VDMDBG.dll is not found.  Reinstalling the application may fix this problem.

    I downloaded a copy of XP Pro SP3 file you need on my SkyDrive (everyone has a SkyDrive for file sharing).

    You can download it and when you do, place a copy of the file in these two folders (assuming that Windows is installed on your C drive):

    c:\Windows\System32
    c:\Windows\System32\dllcache (this is where XP keeps backups of important files).

    Here is the link to my SkyDrive and you can get the file you need here:
    http://CID-6a7e789cab1d6f39.SkyDrive.live.com/redir.aspx?RESID=6A7E789CAB1D6F39! 311

    When you see the files available for download, you will not see the extension of file (.exe, .dll, .cpl, .sys, etc), but when download you them they will have the right extension.

    When you download the file (especially if you use Internet Explorer), when you get a chance to save the file, it cannot save the file with an extension (for example, .exe, .dll, .cpl, .sys) then you will need to manually add the extension appropriate to the file when you download the file before you save it.

    You can download the file without the extension, and then rename the file to add the appropriate extension.  You do not want to use a file called vdmdbg when the name of the file should really be called vdmdbg.dll (if the downloaded file has no extension, you will need to change the name of the file to add the appropriate extension to make it work.

    You then put the downloaded files in the correct folders on your system.

    PS Microsoft support engineers - "try running sfc/scannow and check if it helps" will not replace the missing vdmdbg.dll file because it is not what sfc/scannow does.  If you want to see an experiment to prove that, let me know because I have a ready-made.

  • Loading of a DLL on RT: Missing Export "DecodePointer" "Kernel32.dll" and 7 error when calling the DLL

    Hi, I recently changed to Visual Studio 2010 and Windows 7 64-bit.

    I have an existing Office RT system running RT 2009.  This system calls a DLL that I already built using Visual Studio .net 2003 and Windows XP.

    Since I've recompiled the DLL I get an error 7 file not found error when I call the RT DLL, even if I simply replaced the old DLL with a new one in the file system so the path has not changed.

    I also noticed that the message on the screen connected to the RT system during startup:

    "achieveworldpeace.dll" load error: lack of export 'DecodePointer' of ' Kernel32.dll'.

    Any ideas on this problem?  It is perhaps as simple as a switch in the compiler?

    Thank you.

    I'm not sure it's a simple switch in the project settings in Visual C. The problem is clearly in the standard C runtime library that gets linked to your DLL and refers to exports of Windows which are not available on the RT system. Don't forget that the RT system is a limited Win32 API emulation.

    I usually avoid these problems using Visual C 6 to create DLLs for LabVIEW projects. The standard library of the C runtimes will not know what Windows API reference more recent exports because they have supported even under Win95. So unless your explicitedly reference code not supported RT APIs you wouldn't have problems. If you do not use the standard C file i/o functions and management of memory in your DLL functions, you can also try to link statically C runtime libraries in your DLL, or vice versa depending on what you have now. It may or may not work. Otherwise there is not much else but by using an earlier version of Visual Studio.

    Ive been trying to install Red Alert: Command and Conquer on my new pc windows 7 and of course he will not play to come with all can't play because its running windows 6.1 and it's a single program of windows 95. then I went through all troubleshooting and change everything to make sure that it works and it actually installed, but when I went to play this message appears and im like why does this happen to me!

    The procedure entry point SMapLS_IP_EBP_12 be found in KERNEL32.dll dynamic link library.

    It of the message, can someone help me?

    Hi BigAl3000,

    Please note that Command & Conquer: Red Alert 3 is the only version compatible with Windows 7.

    Red Alert 2 and red alert are not compatible with Windows 7.

    See Windows 7 compatibility for Command & Conquer: Red Alert for more information.

    To troubleshoot program compatibility issues in Windows 7, try the following methods:

     

    Method 1: Open the program compatibility problems

     

    Most programs written for Windows Vista are also running Windows 7, but some older programs might run poorly or not at all. If an older program does not work, use the program compatibility issues to simulate the behavior of earlier versions of Windows.

    Method 2: Contact the program vendor or the hardware manufacturer

     

    Contact the program vendor for advice on how to solve the problem. In general, the software vendor's Web site provides a support section that you can use, for example, to search for an error message that you receive from the program.

    Hope this information helps.

  • Error: ' ATL. DLL was not found"when trying to run any application.

    Original title: ATL. DLL was not found.

    I can't run applications in my pc someone in my house could not get into the computer and changed operating system to windows xp, which allows to be decommissioning of this t. Now, I get this message when I try to run an application: the application failed, because ATL DLL is not found, re - install the applicationmight solve the problem, but I get this message after you have re-installed and I don't know what else to do. Slow computer charges and freezing, something he has never done before. Same IE you have a problem, the only thing that works well, it is the remote assistant who helped me to get here and to him intermet, actually all of this with the dll thing started after I deleted the firefox browser because it froze the computer. Unable to restore my recovery utility, I tried a TI ran and told me it is impossible to get it back before I uninstalled firefox.

    Unfortunately, the support engineer technical 'expert' who is hired by the tips from Microsoft to run sfc/scannow will not help you.

    I would say that, as usual, the technical support engineer has not bothered to reproduce the problem and tried their own suggestion.

    If the atl.dll file is missing, sfc/scannow will launch but it does not work.

    It's just another wild goose chaseSupport Engineer.

    A lot of things will not work if the atl.dll file are missing.  System Restore will not work, Event Viewer do not work, you will not be able to get on the Internet, etc., until the file has been replaced.

    You try to run the system restore, you see the following message is displayed:

    Rstrui.exe - Unable to locate component
    The application has failed to start because ATL DLL not found.  Reinstalling the application may fix this problem.

    Try to open the event viewer, you see a message like this:

    MMC could not create the snap.
    MMC could not create the snap.  The snap-in may not be installed correctly.

    Name: Event Viewer
    CLSID: {975797FC-4E2A-11D0-B702-00C04FD8DBF7}

    Running sfc/scannow will be launched, but it will not run if the ATL DLL file is missing and you will see events like this in the event log (when you arrive, it works again):

    The server {8BC3F05E-D86B-11D0-A075-00C04FB68820} is not registered with DCOM within the required time.

    You can't get on the Internet using any browser.

    You have to somehow replace the missing or damaged file.

    The file might really be missing if he has been quarantined (actually deleted) by your antivirus not specified.  If the file is simply missing, you can just replace it and then later determine what happened to the file and decide what to do about this.

    You can search Windows on your system for ATL DLL and replace the missing file.

    THE ATL. DLL file must be in this folder (assuming that Windows is installed on your C drive):

    c:\Windows\System32

    Check and see if you can find the ATL DLL file in this folder, or if he's really missing, you will need to replace it:

    Depending on what applications you have installed, when you search for your ATL DLL system, you can find ATL DLL in several places on your system.  You must be sure get you the correct that belongs in c:\windows\system32.

    The most likely place to find a good copy of Atlant. DLL will be in one of these folders:

    c:\Windows\System32\dllcache
    c:\windows\system32\ServicePackFiles\i386

    Locate a copy of the correct Atlant. DLL from the file in one of these folders and copy/paste in the folder c:\windows\system32.

    Answered in the affirmative if invited to replace the existing file.

    There is a copy of the file on my SkyDrive, you can download a system not affiliated and then copy the file to a Flash DRIVE or a floppy disk and apply it on the afflicted system c:\windows\system32 folder.  Here's how:

    I downloaded a copy of XP Pro SP3 file you need on my SkyDrive (everyone has a SkyDrive for file sharing).

    You can download it and when you do, place a copy of the file in these two folders (assuming that Windows is installed on your C drive):

    c:\Windows\System32
    c:\Windows\System32\dllcache (this is where XP keeps backups of important files).

    Here is the link to my SkyDrive and you can get the file you need here:

    https://SkyDrive.live.com/?CID=6a7e789cab1d6f39&ID=6A7E789CAB1D6F39! 311

    When you see the files available for download, you can not see the file extension (.exe, .dll, .cpl, .sys, .zip, etc.), but when download you them they will have the right extension.

    When you download the file (especially if you use Internet Explorer), when you get a chance to save the file, your browser is unable to save the file with an extension (by example, .exe, .dll, .cpl, .sys, .zip, etc) then you will need to manually add the extension appropriate to the file when you download the file before you save it.

  • Reviews for .dll file loading error when starting the laptop

    After removing an infection from malware Thinkpoint of my laptop and reconstituted at almost normal speed, a notice of a .dll file loading error appears while booting.  What are the options to eliminate that?

    This isn't a lot of information to go, but it's because forums MS Answers does not prompt for information, when a new question is asked.

    Thank you MS Answers, allowing the resolution of simple problems as frustrating and a lot of time as possible.

    Read this and see if it looks like your question and if it is not, let us know exactly what you see and we will always fix it:

    Here are the detailed instructions that protect you and solve your problem in the 'right' way.

    If you do not have a good explanation for the name of the file in a Google search, the chances are good that your system is currently or has been infected by malware.

    A "Cannot find...". ', ' Failed to start..., "Could not load..." ». "Might not work... "" Cannot run ""error loading... ". "or"specific module could not be found"message at startup is usually related to the malware that has been configured to run at startup, but the referenced file has been removed after a malware scan, leaving behind him a startup item or the registry entry pointing to a file that does not exist.
    It might be a removal of malicious software or an application not installed.  The entry may have a curious looking name since it was probably generated at random when the malware was installed. If you search your system for the referenced file, you may not find.
    Windows attempts to load this file but cannot locate because the file has been deleted for most probably during an analysis of the malware. However, an orphaned associate of remainders of startup parameter or registry entry and tells Windows to load the file when you start or connection.
    So you should delete the referenced entry Windows stop trying to load or run the file. It may or may not be included in the registry, but you can find it.  Autoruns (see below) you get the elements no matter where it is.

    You must be sure to solve the problem and not just fix the symptom of the problem by simply relieving your message - system is not a fix (there is a difference).

    If you just locate and uncheck the item in msconfig, which disables the element but does not remove the reference to the element of false starting your computer.   The msconfig program is not a Startup Manager, that's a troubleshooting tool.  Disabling things in msconfig to put an end to the messages and think that your problem is solved is short-sighted and leave behind him a sloppy XP configuration.  Just disable the display of a start-up error message should not count as a 'solution' to the problem.
    If you are comfortable editing the registry, you can find and remove the reference directly from there or remove it using a popular third-party tool called Autoruns.  The problem can always be found in the registry well.
    Before making any changes to your registry by hand or with third-party tools, don't forget to first make a backup of the registry. There is no cancellation or exit without saving the option in regedit.
    Here is a link to a popular registry backup tool:
    You can also use the Autoruns to find the element of start remains little matter where he's hiding.  Autoruns does not install anything on your computer.  It will display all startup locations where the reference may be then you can turn it off or remove it completely.  Here is the download link for Autoruns:
    Run Autoruns.exe and wait that he at the end of the filling of the list of entries.
    When the Autoruns is finished scanning your system, it will say "Ready" in the lower left corner.  Autoruns can be a little intimidating to first if you have never seen it before because it displays a lot of information
    .  You are really interested only a few sections.
    The problem is usually to start the system or the user startup entries, then click the connection tab and see if the startup item is there.
    Scroll through the list and look for a boot entry associated files in the error message.
    If you can't find on the connection tab, look in any tab.
    You can also click file, search to search for logon, or any tab for all or part of the name of the element.
    Right-click on the offending entry and choose Remove.  If you are not sure what it is, you can simply disable, restart and if the problem is resolved and then remove the offending entry.  If you don't see it in Autoruns, you may edit the registry and remove the item from your startup folder it.  Autoruns shall display the same information however.
    Given that your system has or has had an infection, follow up with this:
    Perform scans for malware, and then fix any problems:
    Download, install, update and do a full scan with these free malware detection programs:
    Malwarebytes (MMFA): http://malwarebytes.org/
    SUPERAntiSpyware: (SAS): http://www.superantispyware.com/
    They can be uninstalled later if you wish.
    Restart your computer and solve the outstanding issues.
