No sound on HP DC7800 since equipped AMD Radeon HD6450 graphics card.

Hello

I just bought HP DC7800 PC with no operating system. I installed Windows XP SP3 with all updates to the OS and an AMD Radeon HD6450 video card. When the OS is on there is no sound. BIOS (v1.32) has Intel HD audio that is enabled. I tried to change settings in the Bios under devices PCI IRQ 5, 10 and 11 - nothing has changed. I installed Microsoft UAA and reinstalled the Realtek audio driver, but still have no audio. Any ideas?

You are the very welcome.

I have a dc7800 CMT

I installed the Radion HD 6570 and lost my whole integrated audio system as you did.

I know where you are in the BIOS, and this isn't in the right place.

Is there a device Options menu, under the Advanced menu.

This is where you find the setting.

See page 10 on the link below. There is no audio menu embedded in the manual because it does not appear when you add an audio or video HDMI card.

    I'm not sure of what you ask for because you indicated that you are sure that it is the CPU but you have what it takes to update the graphics card.   You can use the management tasks (resource monitor) to monitor the CPU usage while the game is active and see if the CPU is limited (more than 70%).

    There is no way to predict how 20 cars will react to? resolution settings and unknown game?

    I'm downgrading my Pavilion 17 f004dx to Windows 7 Pro.  I have the Pro Windows 7 64 bit responsible and all windows updates for it so far.  I'm having a problem with the installation of the video drivers.  For some reason any the AMD Catalyst video driver utility does not see the specific video hardware video card model AMD Radeon HD graphics on the display card.  Windows 7 Pro keeps defining it as the "Standard VGA graphics card".  Does anyone know what it should be showing under display adapters in Device Manager.

    Hello:

    I think I finally found a driver that works.

    None of the other drivers that we tried was the hardware ID for the GPU to your laptop, but this one doesn't.

    This package provides the AMD graphics driver high definition (HD) and Catalyst Control Center for models of laptop computers that are running an operating system supported. For laptops equipped with switchable graphics modes, this package contains the drivers for the two graphics (GPU). Switchable graphics allow users to switch between a graphical power mode (normally used under the power of the battery) and a mode of graphics performance. If the video output high-definition multimedia interface (HDMI) is supported, this package also installs the HDMI Audio Driver.

    File name: sp69161.exe

    You may need to install the driver manually if auto installation does not work.

  • HP 8200 elite CMT: can I use an external power supply for AMD Radeon HD graphics card 7770?

    I have HP 8200 elite CMT CPU in which 320 watts PSU is installed. I want to use AMD Radeon HD 7770 requiring more power (minimum 400 watts power supply) for maximum performance. But the fact is, the higher Watt PSU is not available for my cpu because its cables do not match that. So I ask if I can use the external power supply to power my GPU instead of the CPU power. Will be this harm to my PC?

    Kindly help me to solve this problem.

    Hi DevangS,

    If you use GTA 4, which would actually be the problem. According to PC system requirements for GTA 4 it is only compatible with Windows Vista and Windows XP. Also, the game requires a minimum of a processor clocked at 1.8 GHz and your model has only 1.7 GHz. You try to run an older game on the wrong operating system with hardware that does not meet the conditions required for the game. Change the BIOS or the net won't help with this question.

  • An AMD Radeon 6970 graphics card will be compatible with my desktop computer?

    -INtel Core i7-2600 processor

    -16 GB of ddr3 RAM memory

    -460W power supply

    From now on, I have an AMD Radeon 6850 in my office, but I want to know that if I buy a 6970, if it will be compatible in my office and if not will work properly. Or if he simply does not work.

    Please answer as soon as possible because I need to know whether or not it is necessary to collect money for her for Christmas!

    Thank you!

    Hello

    Make sure that this AMD Sapphire 6970 will adjust.  It is 9.8 "length.  I also checked the length on the Sapphire site.  It's a card double slot.  This map requires a PCI-E power connector 8 pins.

    The Corsair CX600 is sufficient for the video card above.

    You can review the performance comparison between the 6850 and 6970 to this site.  Notice the power for the use of 6970 which means more heat inside your PC.

    The range is not related to the bit depth. You will get the wide range without worrying.

  • In the properties of PC / Hardware list how many times must be A-6-3400 M AMD APU with Radeon HD graphics card?

    My system is a Toshiba laptop Windows 7 Home Edition 64-bit. 282 concerts.  I got a message display and went through the troubleshooting. A message could not be sent to Microsoft. Let me know I had an AMD graphics card problem, but that is as far as the resolution of the problems went. When you open the properties of PC / hardware display I see four lists of my AMD A-6-3400 M APU with Radeon HD graphics card, there is only a display for this laptop I think that the problem would be that there are files repeated unit of AMD.  If there is a problem, how could get rid of the unnecessary quotes? I went to the AMD driver update thru and have downloaded the Downloader driver AMD and then installed the catalyst_mobility_64bit_util.exe.

    Hi TerryDonceel,

    According to the description of the issue, it seems that you see the A-6-3400 AMD M APU with Radeon HD graphics card appears several times under properties PC / hardware.

    It depends on the number of nuclei which is how the processor is divided is indicated in the properties of PC, in your case, there are four virtual cores for the motherboard which is why it appears several times.

  • Three monitors on two AMD Radeon HD7470 video cards

    I just got a Minitour OptiPlex 9010 with 2 dual AMD Radeon HD7470 1 GB graphics cards.  When I placed my order, I told them that I wanted to connect three monitors.  The VGA port has been inactive for other video cards have been installed.  I've been on technical support for more than three hours, when they finally decided to send a tech.  He was released the next day and told me that I needed a split adapter.  I ordered an and he hung up but there was showed the same jobs and I was unable to make changes to the resolution, etc.  Video cards have a DVI and a displayport.  I can connect a DVI monitor and others in the displayport and the monitor then third on the second video card?  Or can I just add another video card to the Tower?  Any help would be greatly appreciated.  Thank you!

    Hi pbondcb,

    You must connect the first monitor to the DVI port and the second for the DisplayPort on the first graphics card. The second monitor must be connected to the DisplayPort with the appropriate cable. You can connect the monitor third DVI port on the second graphics card.  You must enable the display via the Catalyst Control Center under Windows, using the Eyefinity function. The third monitor works only in Windows.

    I hope you find this information useful.

    You can try this AMD card in some other unit and check. If you find the problem with the card, get it replaced.

  • AMD Radeon HD/Intel switchable graphics

    Sorry to be the bearer of bad news, but the situation is that you should not do the upgrade of Win10.  Their upgrade tool has done a really poor job of detecting switchable graphics before the updrade, and as a result, people like you end up with machines that are no longer fully functional.  Same thing happened to me.

    With switchable graphics, the only work pilots come from OEM making machines, because the material is suitable, so having to be engines.  MS does not supply these drivers any more than the video card manufacturers.

    So, without driver HP Win10 for your PC, you're stuck with only two results:

    (1) keep Win10 and faced with the problem of graphs

    (2) to return your PC to the original operating system.

    I chose the second because I prefer a PC with an OS more old where everything worked, to a PC with a new operating system, where things don't work.

Well my laptop is not using the AMD Radeon HD M 7730 driver it's just with the intell 4000 driver.

And when I updated the driver AMD could not perform what be the theme aero worked, but I couldn't launch games or videos.
    I know my English is not so good, but I'll do my best to explain what you need if I get assistance.

    Hi Gubamaharama,

    I answer on behalf of Dell Amogh G.

    Laptops with a switchable graphics feature have two graphics (GPU) - an energy-saving, Integrated GPU and a powerful, discreet GPU. Computers equipped with a power saving GPU Intel and an AMD high performance GPU combine the advantages of low power of a GPU integrated with maximum performance of a discrete GPU.

    By default, a computer with switchable graphics uses the integrated or energy conservation, GPU for most applications. The computer switches automatically to the discreet or high-performance GPU when an application requires more performance. You can configure the applications that require the GPU performance by selecting the application in the Catalyst Control Center software. When an application is configured to use the GPU high-performance computer rocking graphics solutions when the application is started or closed.

    You can check the video below on how to configure the AMD Radeon switchable graphics card:

    cs_setInnerHtml ('video_2c182906-7926 - 4ca 8-9951 - 8b78edf0e5e6', ");

    I hope this helps. Answer please if you have any questions.
