This drivers don't work. I can't install the sound, I have installed first the Microsoft Universal Audio Architecture (UAA) Bus Driver, but the sound driver is not good. The wireless is the same, not good. The others I haven't tried. what can I do???

i installed the linked xp drivers for my downgraded C751nr, however while the sound card now works i have no volume controll, is this something that can be easily fixed or should i just run no sound?

Are rest of these drivers (other than audio) working for you?
Please make sure that you have Service Pack 2 installed for Windows XP

Team Zyxware

Service pack 2 or 3 usually contain the drivers you need.

I am having the same problem with the audio driver, the first installs correctly at which point windows recognizes an audio device and prompts for driver installation. I cancel and attempt the second part but it errors with the message: Driver Installation Failed: Could not find MEDIA device for this driver. Thanks for any help

The driver must be different for you.
Normally drivers are common for all C700 series laptops. Kindly try drivers for the same device from other laptop entries in our website.
Let us know what happens

sound drivers and wifi,wireless lan is not working up to now sir.

Please help me get my sound drivers working on my C500 Compaq Presario Notebook

NONE of the drivers worked on my C751NR, except for the Chipset, the Quick Launch buttons and the Touchpad, which gave no errors on install.
Video: PCI\VEN_8086&DEV_2A03&SUBSYS_30D9103C&REV_03
Audio: HDAUDIO\FUNC_01&VEN_14F1&DEV_5051&SUBSYS_103C30D9
Modem: HDAUDIO\FUNC_02&VEN_14F1&DEV_5051&SUBSYS_103C30D9
Network: Realtek 8139 and using standard Windows drivers (not a Marvell).
Wireless: used the ones for AR5006X from
Touchpad: Using ALPS drivers, SP31075

This machine has no card reader.
None of the mentioned hardware IDs are found inside the .inf files of the drivers.

Any clues?

In order to install WinXP on c751nr download chipset driver, video driver and INF update utility from, install them. Then download the UAA driver from (kb111888.exe). Alternatively, you can use Windows Update, it will install the driver automatically. Once that is done, the Device Manager will find sound card and modem and will suggest to install drivers for them - choose the option to install the drivers through Windows Update - both drivers will be installed and will work without any problems. After that install drivers for ALPS - you can find them at the HP site, drivers from a different laptop model will do the trick. Finally, install WiFi drivers that can be found here: - use the latest version of the WHQL signed (that's important, unsigned drivers won't work) drivers for 5006EG. Drivers for the network card are installed by Windows during installation. Looks like this is it - good luck.

Thank you for your support. Really appreciate your effort.

Dear Mikhail,

In case you have, could you please post the links of these drivers which you had mentioned in your comment ? That would be of real help for others.

I may try to find all the links I used for downloading the drivers, but I cannot guarantee all of them will be found. Alternatively, if you could provide some storage space, I could upload all the drivers found in a single shot - it would also be easier for people to download all the drivers needed from one place.

Regards / Denis

Dear Mr. Denis,

thank you for your co-operation. But I am afraid I will not be able to provide you storage space of any kind. If you have noticed, we ourselves are not keeping any drivers with us, as these are the property of the manufacturer and many of these drivers are stored in the ftp servers of the company. We just provide the links pointing to the same. If you could post the links here, it would be really helpful.
I don't think there is a requirement for a second place to store for these files, as they are already present on the web. It is just that we have to spend some time and search for them.

I have win xp home on my new Compaq Presario C713NR. i have all the drivers and it works fine. I have zipped all the files.send me a email at if you need them.

I thought that I had found all the drivers in one location finally. Seems that the Microsoft Universal Audio Architecture (UAA) was going to fix
the audio and modem because seems to have recognized new entries in Device Manager. I tried installing the Audio and Modem drivers from the
this website. Using the following instructions.

After downloading and installing UAA driver, restart the Notebook and then install Audio Driver:

Similarly install Modem Driver:

Both failed with this message as well:
Driver Installation Failed: Could not find MEDIA device for this driver. for the audio
Driver Installation Failed: Could not find MODEM device for this driver. for the modem.

Any ideas? Thanks for all the help.

Same model of laptops can contain hardware of different make. Hence the drivers needed also vary. I believe the hardware in your machine not for the drivers given here. Please try installing alternate drivers of the same series.

I've seen this issue before. Try different revisions of the same driver. Try newer and older versions. I had this problem downgrading an HP laptop, and a different revision of the UAA driver solved the issue.

Hi this web is good, but the drivers in my laptop no open

my model is presario C751LA

So, Can you gather all the neccesary drivers for Windows XP Service Pack 2 Professional Edition for this laptop and provide me the links where I can get them?

i finally got my sound to work, but it sounds very muffled, as if its being covered by something... any help?


I dont speak english so I speak spanish...

Hola, de acuerdo con lo leido , algo eh ententido de lo que plantean , y yo tengo el mismo problema con el audio en mi presario c 751 LA , no me reproduce ningun sonido despues de haberle instalado el windows XP , ademas un amigo habia logrado arreglar este problema pero aun seguia teniendo problema con el microfono por que no me funcionaba...

Si alguien puede ayudarme con estos dos problemas por favor....

Yo no hablo español. Se trata de utilizar "google-traducir"

Este es un problema común con todos los HP-Compaq portátiles. Todos los últimos modelos están diseñados para trabajar sólo con Windows Vista. La empresa no admite el uso de XP en cualquiera de sus productos. El problema se produce debido a la incompatibilidad conductor. Todos los ordenadores portátiles más recientes vienen con el hardware más reciente que requieren controladores más recientes. Pero los conductores de XP son mayores de versión.
Una de ellas es usar Windows Vista.
Pero quisiera pedir que usted utilice GNU / Linux. Son muy sencillos de utilizar y disponible para su descarga gratuita en Internet. Algunos nombres incluyen - Ubuntu, Kubuntu, Mandriva, SUSE, etc

Compaq Presario C751LA viene con Windows Vista, ¿verdad?

This is a common problem with all HP-Compaq laptops. All latest models are designed to work only with Windows Vista. The company does not support use of XP in any of their products. The problem occurs due to driver incompatibility. All latest laptops come with latest hardware which require latest drivers. But drivers for XP are of older version.
One suggestion is to use Windows Vista.
But I would like to request you to use GNU/Linux. They are very simple to use and available for free download on internet. Some names include - Ubuntu, Kubuntu, Mandriva, OpenSuse etc.

Compaq Presario C751LA came with Windows Vista, right?

Hello, I have a C751LA with XP SP3 and no audio works. Do you have a solution for this problem? or we have tou change to vista ot linux?....

sorry about my english?




Querido Juan

Yo no hablo el idioma que usted. Pero me acaba de hacer un intento a través de Google-traducir.

Estos vínculos han sido dadas por el fabricante. En general todos los conductores son comunes para Compaq Presario C700 series de ordenadores portátiles. Puede intentar la instalación de controladores para cualquier webcam de otros modelos, disponible en nuestra página web. Pero no hay garantía de que estos conductores funcionan perfectamente con Windows XP

Dear Juan

I do not speak you language. But I am just making a try using Google-Translate.

These links were given by the manufacturer. Generally all driver are common for Compaq Presario C700 series laptops. You can try installing drivers for webcam from any other models, available in our website. But there is no guarantee that these drivers will work perfectly with Windows XP

hola.. bueno postiaba aca porque tengo un compaq presario 751 y le instale windows xp y el microfono no me funciona.. queria saber si alguien tiene una solucion para esto.. saludos y espero respuestas pronto

Well if you all had read the "opening paragraph" it does say that the drivers were not tested. I don't know about you, but whenever I hear or read that I never expect for the item to work.

this is the perfect site....for all the drivers...for the presario c500 laptop

the intsruction are simple and straight forward...YES IT WORKS...

While i have been trying for last three days to find correct connexent xp driver for my c751nr, its all invain. The speakers are working but the built in mic of my compaq presario is not working. external mic does work though. Nobody is writing about the mic problem. I guess the c751nr owners are just testing the speakers. Let me know if the buil in mic is working for you after xp downgrade.


You saved me from hours of googling to find the drivers. Thank you!

wow... thanks..... u save me...

I downgraded my compaq c751nr to XP and i have problem with my VGA and sound what do i do?

I'm also having problems with the VGA. If you find out anything let me know.
