  • HP Pavilion g6-1301tx Notebook PC/ Not able to install AMD graphic driver.

    My HP Pavilion g6-1301tx Notebook PC 4gb RAM is 2 years old,My original OS was Windows 7 Home basic 64 bits then i changed it to Windows 7 Ultimate 64 bits.
    ERROR......................
    In device manager under display adapter there are two GPUs i.e. Intel Hd graphics 3000 its alright and Standard VGA graphic adapter which contains error (this Device cannot start code 10). I tried to update the driver in device manager itself but it tells ( Windows found the driver for the device but unable to install), I even tried windows update there it shows the driver update but whent i try to install it shows error Code 80070002.
    Because of this im unable to play games and watch hd videos in my laptop.
    Please some one help me to solve this problem.

    Hi:
    The only graphics driver you should install for your model is the AMD graphics driver which will install both the AMD and Intel GPU's.
    If you installed the Intel graphics driver from your PC's support and driver page, that could be preventing the correct AMD driver from installing.

  • Installing AMD graphic driver turns into BSOD

    Hello, I have recently reinstalled Windows on my laptop and now i can't install AMD graphic driver. Whenever I try to install it, my screen switch off ( as usual during installing of graphic driver) and then turns into BSOD with error "atikmpag.sys". After this, I am unable to switch on my computer, because there is always BSOD waiting for me and I have to reinstall windows again. This is happening with Win 8.1 and with Win 7. I have tried many versions(releases) of drivers and many ways to install them. But the result is always the same: BSOD "atikmpag.sys".
    Could u give me any solution for my problem? It is really frustrating. I am not very used to write in English, please excuse me. Regards, Patrik Obrtlík 

    AMD's 'catalyst clean utility' (stand-alone program) is notoriously bad, yes especially for switchable graphics laptops. And have heard some horror stories of that ruining windows installations needing a reinstall DDU, I would argue is perfectly safe however. It is pretty universal generic clean utility which can clean both AMD and Intel components. I use it myself(HP envy 15 with AMD+Intel), though AMD catalyst install manager (from 'uninstall or change programs' list) would work, though I don't think it cleans/removes Intel installations. 

  • 'No AMD graphics driver is installed..'

    Hi, I've recently been receiving this message 'No amd graphics driver installed or is not functioning properly. Please install the amd driver appropiate for your amd software' on my pavilion dv6 and I'm not sure why? When I look in the Device Manager under Display adapters there are 2 graphics cards showing - AMD Radeon HD 7400M Series (which has the following device status 'Windows has stopped this device because it has reported problems. (Code 43)' which I assume is where the problem lies and the other one is ATI Mobility Radeon HD 4200 Series which has the device status 'No drivers are installed for this device.' I have tried disabling each one and looking for updates but nothing seems to work. I recently upgraded to Windows 10 from Windows 7 but the issue was there before the upgrade. Any help would be much appreciated! 

    Then you should not do it by yourself, find a friend who knows what the BIOS is and how to reset it to its default settings and request him/her to help you

  • HP Pavilion dv6t-6c00 CTO Entertainment Notebook PC AMD Graphics driver

    I have been having this problem for over a year (my warranty had conveniently just expired right before this started happening). It first started when I plugged in my computer to my tv through an HDMI cord (which I had done before with no problems). My computer shut down after loading up a game and when I finally got my computer back up and running, it said my AMD graphics card driver was not working properly. Every time I tried to repair or update it through the HP Website via the drivers list, it would crash my computer. After I unstalled the driver completely, it STILL crashes my computer upon trying to  now re install it. I am very frustrated and at a loss, and I know there have been a lot of problems with these drivers in the past. They haven't even been updated since 2011... I built this computer to be a gaming lap top, and at this point it is just a suped up paper weight as there's no point in even having 8GB of RAM or 1TB of hard drive memory if I can't even run my games on it... Has anyone had this problem or found a solution to it?

  • No AMD graphics driver installed

    Hi everyone, I trust all is well. I'm having a bit of a problem on my side. I formated my HP Pavilion dv6-6080ei last night and now that I'm trying to install my drivers I keep on getting the following message: "No AMD grapics driver is installed. or the AMD driver is not functioning properly. Please install driver appropriate for your amd hardware." Your assistance will be greatly appreciated. Kind regards

    Hi: I think that HP only supports your model for 64 bit operating systems. The graphics driver you need is the 5th (last) one listed under the graphics section of the driver page below. http://support.hp.com/us-en/drivers/selfservice/HP-Pavilion-dv6-6000-Entertainment-Notebook-PC-series/5048664/model/5076715 If you get an error that says the driver is for 64 bit only, let me know and I will see if I can find the 32 bit driver you need.

  • Boot Camp - "No AMD graphics driver is installed" error during win8.1 post-install

    I have Macbkook pro early 2011 (i7 2.2ghz, 16 GB RAM, radeon 6750M 1GB)
    I used boot camp utility to install win 8.1 - it completed without any problems.
    When the installation was completed the bootcamp wizard opened automaticaly and this was shoved to my face:

    When I wanted to boot to windows I was constantly welcomed by black screen after the "windows splash-screen-spinning-animation thingy".
    I went to safe mode to see what's going on. It turned out that if I TURN OFF my INTEL HD 3000 driver then I can boot to normal mode but
    the 6750M drivers have yellow exclamation mark (error 43 in details) in device manager. I need that gpu enabled since I do some game developent which requires gpu power. I tried reinstalling ati drivers and looking for new ones on the internet - each of them failed. What could be the problem?
    Can anyone help me out?

    Hello HPENVYm6-1201TX,
    I have read your post on how your notebook computer is producing an error message in regards to your AMD driver, and I would be happy to assist you in this matter!
    To ensure that the software is installed and functioning properly, I recommend performing a clean boot on your notebook. To do this, please follow this document on How to perform a clean boot in Windows. This should help eliminate software conflicts that occur when you install a program or an update or when you run a program in Windows.
    The next step I suggest is to remove the AMD driver installed on your computer, and install the driver provided on HP's website. If you need to, you can use this document on how to remove software from Windows 8.1. You can find the necessary driver by click on the AMD High-Definition (HD) Graphics Driver.     
    Instead of updating the driver from AMD's website, please follow this document on Using HP Support Assistant (Windows 8) to update the necessary drivers.
    Please re-post with the results of your troubleshooting, and I look forward to your reply!

    Hello @Peeedge,
    Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
    I have read your post on how your notebook computer is not able to successfully install the necessary AMD drivers, and I would be happy to assist you in this matter!
    To successfully re-enable the Catalyst Control Center on your system, I recommend installing the original software and hardware drivers that first came with your notebook. This can be done by following the steps in this document on Using Recovery Manager to Restore Software and Drivers (Windows 7). Once installed, please follow this resource on Using HP Support Assistant (Windows 7) to update the drivers and software.
    Please re-post with the results of your troubleshooting, and I look forward to your reply!

  • AMD Graphics driver issue

    so i installed the newest build and i receive an error from AMD saying there's no driver or isn't responding correctly so i reinstalled the driver for it 3 times and still no success i will attempt to uninstall the current drivers for it and reinstall but
    i need some assistance on this

    Try this: Download AMD Catalyst Omega 14.12 for your Hardware. Extract its content. Go to Control Panel -> Devices manager -> Choose device Update driver for this device -> Give exact pathway for extracted content of Catalyst 14.12 -> Wait until
    driver is installed. Reeboot.
    After reeboot U should have your radeon listed in Device Manager. But there will be no Catalyst Suite. To install it, start normall installation process of AMD Catalyst Omega 14.12 (choose customized install) Thick to instal Catalyst Suite.
    Now U have device and Suite installed. Works like a charm with AMD 7700M, Intel 4000HD switchable graphics & Windows 10 Technical Preview v. 9926
    Best Regards

  • AMD High-Definition Graphics Driver Problem

    Hi
    Okay so I play a game called "The Sims 4", and if any of you are familiar with it then you know what I am talking about when I say I am testing mods out. I was doing this for a couple hours and came across some bad mods, so I delete them. Well I put a few more mods in my game and went in, everything seemed fine, then got out. When I went to go back in an error message came up saying "No AMD graphics driver is installed, or the AMD driver is not functioning properly. Please install the AMD driver appropriate for your AMD hardware." I then proceeded into my game which did not work. So I came onto this site to update my driver and downloaded the "AMD High-Definition Graphics Driver". There was two options both the same name and same description one was a few megabite larger. After then I restarted my computer tried my game out and it still did not work. I then took out the mods I put into my game right before this all went haywire, and my game worked....BUT VERYYYY LAGGY! I was so frustrated with this that I shut down my computer hoping a miricle would happen next time I turned it on....only to turn it on this morning and that SAME error message came up! SO NOW WHAT? How to I unistall the graphics driver I downloaded (becuase I think its making my game laggy and it did not solve the initial problem.
    Any help is appricated! - Lulejojo

    Thank you so much indeed,
    Could you please take some of your precious time out to really answer these questions below of mine?
    Firstly:: I really have run this Utility(amdcleanuputility) to remove all components of the prvious installation of AMD Radeon and Mobile Inte Graphics.
    I was propmted that  tool will do as it is shown below in the screen shot.
    I agreed. Then, it completed. Is 'AMD cleanup utility' recommended by you?
    Then, the graphics adapters in the device manager became as follows:
    Secondly: I think that it is now the point to reinstall AMD High-Definition Graphics Driver_Software Packaging Numbr(SP55092)_Driver Version 8.882.2.3000.
    Thirdly: Moreover, I would be saying that I lost the audio on my System once the (amdcleanuputility) has completed, although its icon is still intact(screen shot below)
    Must I need to reinstall IDT High-Definition (HD) Audio Driver_Sp55094_Version6.10.6345.0????
    Finally::  in your link about downloading the drivers for my product name. I found Driver-Graphics (5) . However, all what I need is the finall one which is an already-downloaded file with me. Could you please let me know what about the other four graphics drivers????????

  • Satellite C855-1JD Amd Radeon Driver

    Good morning,
    When I turned on my computer this morning I received this message:
    "The Catalyst Control Center is not supported by the driver version of you enabled graphics adapter. Please update your AMD graphics driver, or enable your AMD adapter using the Displays Manager"
    My display adapter is an AMD Radeon HD 7610M
    Any help is greatly appreciated!
    Thank you very much in advance.

    Try to uninstall the ATI graphic card driver which is preinstalled on your unit.
    Then visit the Toshiba EU driver page and download the latest available ATI/AMD GPU driver.
    After the installation has finished, reboot the notebook and check the functionality.

  • Graphic driver

    Usually which driver to install to get rid of the problem of not able to change the screen brightness (HP 450 Notebook)

    Hi:
    Usually the Intel one.
    But if your notebook has an AMD/Intel switchable graphics configuration, you only install the AMD graphics driver which installs the drivers for both the AMD and Intel GPU's.
