• NIC is not in the list of devices Win

  Hi all

  I have a Pavillion Elite 9300 Z running Win 7 (64). It is now about 2 1/2 years. I only rarely use it now since I built a more recent/fast PC last year. When I turned on the Pavilion this morning, I discovered that my internet was not
  work. He had been in the past & I have not changed anything.

  Later, after having checked my connections, I found that my NETWORK card is not in the list of devices Win. At this point, I didn't know what to do. So, I tried to 'Add' a new feature, but way of Win 7 wouldn't let me add a device directly, rather it wanted to 'look' for the devices 'detectable '. After more than 15 minutes of searching without results, I abandoned it.

  I decided to install a driver from HP site. Since this is a .exe file, I thought, it will probably work. But, he didn't, even after reboot, still no NETWORK card in Device Manager.

  Can someone help me solve this problem?

  Hi PieLam. If your NETWORK adapter is not displayed in Device Manager, it has very probably been disabled in the BIOS.
  Here is a link showing how to enter the BIOS. Take a look at the screen shot under 'Advanced menu settings' and note the Onboard LAN option. If you have integrated NETWORK interface, then you need to set the "Enabled".

• Basket PXI in Win 7 Device Manager unknown device

  I'm dealing with a flakey PC that don't become flakey recently, and I don't know why...

  The problem I see is that the PXI basket is a unknown device in Win 7 peripheral Manager.

  Is there some sort of service or the driver available to fix this?

  I am using a third party card that was installed and working on this system for over a year

  and have swapped it out and also swapped the motherboard. I contacted the technical support of the mfg and this error only

  appears when the PXI ((NI PXIe-1065) basket is connected via the NI PXI-PCI8360.)

  How can I fix it?

  Thank you

  

  Hey robojeff,

  I think that what we are looking for is PXI Platform Services (http://www.ni.com/download/pxi-platform-services-15.0/5404/en/).

  It is the main factor that makes the PXI accessible to the computer systems. Let me know if that helps!

  Best,

• Windows 10 Device Manager: "unknown devices", ACPI (Aspire V3 - 112 p)

  After a new installation of Windows 10 (64-bit / Education version) on my Aspire V3-112 p-P5B3, I have yet three "unknown devices" in my device manager and a warning about my 'SDA Standard compatible SD Host Controller'. The first three say «Drivers not installed...» "and display in the 'Détails' tab the" property: device instance path "with the" value: ACPI\INT33FC\n ' (n = 1,2,3). The "SDA". "says"device pending on another device... ". ». So I think that the last problem could somehow be based on the first three problems (?).

  I installed all the drivers on the Acer site for win 10/64 bit.

  I tried to update the drivers in Device Manager... the problems are still there.

  I used the "driver update utility" Intel... the problems are still there.

  I found some clues on the web about "ACPI\INT33FC\n" - but above all, in my opinion, the strange sites for updates of drivers. But somehow, I don't think these pages...

  Someone at - it a solution for this problem? Or the same problem?

  It's a serious thing? Should / can I ignore it? Maybe a future driver updated by Acer?

  Any help is welcome! Thanks in advance!

  ACPI is part of the Intel IO drivers:

  http://global-download.Acer.com/GDFiles/driver/IO%20Drivers/IO%20Drivers_Intel_603.9600.1948.28229_W...

  Sometimes you have to force the installation manually, then go to ACPI peripheral unknow, update/install drivers manually search for and navigate to the folder drivers and let windows choose the good.

• Re: Equium L20-198 - in Device Manager unknown devices

  Hello
  I have a PSL2ZE Equium L20-198.

  I have trouble with the drivers provided by this site everytime I try to install the driver it stops telling me that the chipset is not supported by the program, so I have these unknown devices left to solve

  Ethernet controller
  modem PCI
  SM bs controller
  controller of SB
  VGA controller

  And even if it is a wireless switch (and it works IE turns the light on). I have no software or the details of the installed wireless (standard) whatever it is!
  Not there at - it no utility driver like all the drivers in one of toshiba!

  Thanks to anyone who repiles in advance as this is driving me crazy!

  Hello

  Do you have what OS installed on your Equium L20?

  Normally, you can download all the drivers on the Toshiba site. Did you check that?
  http://EU.computers.Toshiba-Europe.com-online decision-making supported Downloads & => Download drivers

  I had a similar error message if I tried to install a new driver from chipset, but it worked if I installed the driver in the Device Manager with the Advanced installation order.

• Device Manager - unknown device + Hig Defintion Audio Device (Point of Exclamation)

  Hello

  I hope that someone can help you. The hard drive on my laptop of HP ENVY TS 15 (product number: E3S19UA #ABA) out crapped and I reinstalled Windows Enterprise 8.1. I downloaded and installed all the drivers from the HP website. When I look at the Panel, I have an "unknown device" and in the audio, video and game controllers, I have an exclamation mark next to the high definition Audio Device.

  I installed the HP Support Assistant and let it do its thing. That has not fixed the problem. When I look at the properties for the unknown device, I see the following in detail: "ACPI\HPQ6007\3 & 11583659 & 0" regarding high definition Audio, I see the following in the general tab:

  This device cannot start. (Code 10)

  {Operation failed}
  The requested operation failed.

  When I try to update the driver software fo the High Definition Audio, I get a message that "Windows has determined the software driver for your device is up to date.

  Don't know where to go from here. Any help or words of wisdom would be greatly appreciated.

  Thank you

  -Val

  You are the very welcome.

  This is defininitely the driver you need and you need to install it manually.

  Run the driver again.

  Go to Device Manager and click on the unknown device needing driver.

  Click the driver tab.  Click on set to update driver.  Select Browse my computer for driver software, and find the folder of the driver that was created when you ran the driver.

  This file will be located in C:\SWSetup\sp66078.  Make sure that the include subfolders is selected and see if the pilot goes like this.

  If this does not work, then back to her browse my computer for driver software window and then select Let me pick from a list of drivers for devices on my computer option, then select Have Disk and browse to: C:\SWSetup\sp66078\InstallFiles\Win8_1\accelerometer and select the HP Mobile Data Protection sensor from the list and see if the pilot goes like this.

  The HD audio device is the audio device Intel HDMI which could not install when you ran the graphics driver, so run it again and if it does not install, manually install the driver using the same procedure that I posted to the 3D driveguard.

  If it doesn't, then I remove the driver and tell you where to get the driver from, as I did for the above device.

• Satellite L555-S7008 - can't install Storage Manager Intel for Win XP

  I installed XP on my laptop.

  Everything works fine except that I can't put in Ahci mode.
  I installed xp in compatibility mode, because I'm supposed to be able to install the sata drivers by running the Intel Storage Manager.

  I tried the version on this Web site as well as one of Intel, and they both stop at the error
  "Your computer is not does not meet the minimum requirements for this software.

  I also collected I can extract the drivers from this package and install them manually.
  but when I try it say drivers extracted successfully, but nothing is extracted.

  Can someone please help me get the Storage Manager to install so I can run the Ahci mode.

  Satellite L555-S7008 belongs to the Toshiba US series.
  You need to download the drivers from the Toshiba driver page we:
  http://www.CSD.Toshiba.com/cgi-bin/TAIS/support/JSP/home.jsp

  There is a nursery of storage Intel:

• Toshiba 40RL933G: software to manage movie on Win 7 PC files

  Hi all.

  I am looking for another software than the Windows Media Player to manage my movies on my pc.

  Reason:
  Sometimes I copy a new film in movie library, or I add a new folder to the library and media Player does not index them. ->, I do not see the new movies in the libraty and so I can't go to my toshiba TV and watch the movie with the network of media Player that is built into the TV.

  Some movies I can see at the end of a few seconds or say in the Media Player "are seeking changes in the news media" then I see new films in the library as well as on the tv when I opened the network folder on my TV. But some movies do not appear even after hours of waitung.

  When I remove the database of media player and rebulid them, for the most part it works and I see all the movies, but it takes each time 30 to 40 minutes.

  I am therefore looking for a media player such as Windows Media Player, which can handle this better.

  I have a Toshiba TV and a Windows 7 PC with Media Player 12.0.7601.18150 40RL933G.

  thany for your help.

  Have you installed the driver for bluetooth model corresponding to the model of wireless card that your laptop is?

  If this isn't the case, you need to.

  If so, it would be impossible for me to determine which device must be the driver.
