The HD 5450 M dedicated graphics card not recognized DM4t: SOLVED

I never actually had to post on these forums but be long time lurker ive encountered a big problem.  First stop, I have a HP-DM4T-1000 with switchable graphics and a HD 5450 M map.  Until very recently it works fine.  He was a Catalyst update a few weeks ago during which something I messed up, possibly the update got cancelled while underway I remember exactly.  After that Device Manager don't would not show more ATI graphics card and the graphics in switcable would not work.  Catalyst Manager would say that no device is found.  I already tried updating all ATI software and the driver doesn't have a chance to find this card on my laptop.  Only the integrated card works and I'm really eager to play torchlight 2 when it comes out tomorrow haha.

Are there any available advanced techniques to search manually for a graphics card lost on a device without opening it to the top?

Solved by myself, I had to boot into safe mode and the disabled card itself.  All I had to do was then turn it back on, start in normal mode and install the catalyst through ATI/SUPPORT/C: hard disk Control Manager.

    I'm not able to install Windows 7 or an another Version of Windows. Because I don't have the dedicated graphics card (only the onboard integrated graphics card) and found no BIOS option to turn it off, I would like to remove it from the motherboard. Unfortunately, I wasn't able to find out whether or not the ATI graphics card is welded (which this would make very difficult). Thanks a lot for your answers and a better idea to solve the problem.

    To be honest, it won't be easy to solve your problem. Why?
    Many people who have mobile machines the same logic valid for desktop computers. Exchange upgrade or hardware components on mobile units is very limited and you can simply swap the GPU or change the BIOS settings.

    If the GPU is faulty in many cases entire motherboard must be replaced. I don't know what other people will write here, but what you can do is contact the nearest Toshiba service provider and ask for help or advice what can be done about it.

  • Inspiron 3737 - pass fron integrated to the dedicated graphics card

    Hello

    I got Dell Inspiron 3737 with integrated graphics card Intel 4000 and dedicated Radeon HD8670M graphics card.

    Several weeks ago, I discovered this laptop works only with integrated IntelHD4000 (Win7 x 64). I installed the drivers of the latest GPU to dell, but it's not not to solve the problem. I installed older drivers, but also, there is no problem.

    I decided to reinstall windows.  I installed Windows 7 x 64, all the drivers from the dell site in the order which they suggest. But laptop also only use IntelHD4000. In Device Manager shows two graphics GPU Intel HD Family and AMD Radeon HD8670M. Catalyst, AIDA64 and CPU - Z will find only Intel HD 4000. Reference Dell start diagnostic tools and Dell Online Diagnostics found no no problem (all tests was passed).

    I tried to contact the technical support of Dell and got the following response "what did you want us? You are no longer under warranty and it's your problem! ».

    If I understand correctly the video driver installation and switching between integrated and dedicated graphics are global problem. Solve someone has mentioned the problem and how?

    Go into your BIOS by pressing F2 during startup, go to the Configuration tab and check the graphics device option. If she says the UMA chart change to Switchable Graphics and try the installation again.

  • Pavilion 15 e008-sc: dedicated graphics card update

    Hi one just want to ask if possible to modify and update a dedicated graphics card?

    AMD Radeon HD m 8670 is dedicated to my laptop inside. I want to update this to little graphics card more powerful. I don't want to buy a new machine. It is possible on this type of material.

    If so, that will be good? I can put here nvidia or amd graphics chip, it must be?

    CPU: Intel i5 - 3rd generation 3230 m 2, 6 ghz

    RAM: 8 GB

    I think that the processor and RAM are kind a good but the power of the graphics card is somehow a hollow. Thanks for the reply

    Hello

    Unfortunately, the Radeon HD m 8670 is integrated with the system board and is not an evolutionary element - this is the case for virtually all mobile phones as a consumer.

  • Satellite M60: cannot install the latest driver for my graphics card

    Can not install the latest driver for my graphics card
    Satellite M60
    GRAPHICS ATI MOBILITY RADEON X 700

    Hello

    First of all I'm really putting t understand why you start two topics with the same theme. It is often better to have a subject with good content and interesting comments. Am I wrong? ;)

    Anyway, in your case, it is interesting that Toshiba use adapted drivers because of the material. This means that this graphics card is not required to run at the maximum level. Material cooling in laptops is very problematic and high temperature can cause overheating or a material damage. All hardware components are placed on a small square. Graphics card produces a lot of heat and it is not so good for other material.

    When you use graphic driver non-Toshiba card is forced to run faster. That's any use of support laptop manufacturers don t of third party drivers. The fact is that physical protection is a priority.

    I didn t do all the experiments, but according to some reports on this forum, there is how to install the driver of non-Toshiba graphics card.

    Please check this forum and you can find a lot of comments about this. An interesting topic is http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=18063&messageID=66186

  • CQ5110y - new graphics card not detected

    I have a cq5110y that I am trying to upgrade the graphics on.

    I just installed a bigger power supply and is working on the installation of a Sapphire Radeon R7 240, but when I turn on my computer it does not detect the new hardware.  Am I missing a step?  Or is the card DOA?

    The steps to install the new card were quite simple--plug it into the PCI-e slot and connect the monitor.  There was a note to disable any integrated first graphic, so I put the display to PCI-e in the BIOS.  Is that all I had to do to disable the integrated graphics card?  I think that this could be my problem?

    Your Compaq Presario CQ5110Y desktop uses a chipset NVIDIA GeForce 6150SE nForce 430 seems limited to the PCI Express 1.0 version.  PCIe v1.0 is compatible front of PCIe v2.0.  PCIe v2.1 and above is not backwards comptible with your motherboard. Your Sapphire Radeon R7 240 seems to use a PCIe v3.0 card and is therefore not compatible with your computer. Please return the card for a graphic card PCIe v2.0 solve your problem.

    If you have any other questions, feel free to ask.

  • dedicated graphics card problem

    Hi all!

    I have a HP probook 4530 s and after 2 years of using the dedicated graphics card (ATI Radeon 7470) seems to have a problem. I was playing my game, which is a flash game based on chrome and suddenly the screen frozened. I use by default the ATI graphics card because the system supports switchable graphics. So, after this screen frozen, I turned off my laptop and after I turned once again he doesn't want to go through the screen of windows welcome. I went into safe mode, disabeled ati graphics card and after I restarted again, I could get properly into windows. A funny thing is that after that, I reinstalled windows and the first thing is to install the graphics driver. After clicking on restart my laptop frozened again in the Welcome to windows screen.

    Can anyone help me please with this problem?

    Thank you in advance.

    Try from the BIOS, there is something that you can uncheck it from the BIOS and it will work exclusively on the second card, of the processor.

    The thing is that I found the problem and it is verry annoing. I disassembled my laptop to renew the theat conductor paste and I saw that the old spent was melted by the heat by the graphics card and drained on certain components close to, and I know that this dough is a conductor of electricity now so bye bye dedicated graphics card.
