  Go to the website of the manufacturer of your motherboard support and search for Windows 7 drivers for your specific model number.

  If there are Windows 7 drivers, then download to a folder on your drive hard and install all of them, starting with the card mother/chipset drivers, SATA, LAN, Audio, USB, graphics, Webcam, Etc., and so on.

• P 8470 & HP HP 8440 P: upgrading to W10 Pro 64 bit / device Reporting - unknown device manager

  I have recently upgraded to Windows Pro 64-bit 10.  Machines involved are - 8440p & 8470p running W7 Pro 64-bit.

  The Device Manager shows an unknown device - ACPI\HPQ6000\3 & 33FD14CA & 0.

  Could someone tell me what this is in reference to.  Perhaps point to a driver that I could update.

  Thank you / / Jeff

  You are the very welcome.

  The reason why you don't see the driver is because most of the drivers are missing in support pages, which have not worked directly for HP split into 2 companies from 1 August.

  This is certainly the driver you need.  If the version of W7 works, I can't say.

  See if it works.

  FTP://ftp.HP.com/pub/SoftPaq/sp59001-59500/sp59282.exe

  If this driver does the same thing...

  Go to Device Manager and click on the unknown device of 6000 who need pilots.

  Click on the driver tab, click on set to update driver.  Select her browse my computer for driver software option, then at the bottom of this window, let pick me from a list of drivers for devices on my computer.

  Click on disk and go to C:\SWSetup\sp59282\accelerometer and select the HP Mobile Data Protection sensor and see if the pilot goes like this.

  Here's a partial copy and paste of the accelerometer installation information file.

  As you can see the device is supported by the driver.

  But it's the most recent driver is there, I know.

• No monitor showing in Device Manager

  I have a Hannspree 28 "monitor with a hdmi connection to an Asus Radeon 4890 graphics card. This facility works great under Vista Ultimate 32 bit in the default resolution of 1920 x 1200 screens...

  Since I installed Windows 7 64 bit, in a dual-boot scenario, I was unable to get Windows 7 works correctly in Normal mode, it works in safe mode, but only in 1600 x 1200.

  If I try a boot in Normal mode, then the sequence of boot stalls however I can open Win 7 Normal mode if I remove the Radeon 4890 in the element display adapter in Device Manager. Win 7 install the re - install the 4890, but can't do the correct resolution.

  With the latest ATI drivers installed in the card there is no monitor is displayed in Device Manager at all.

  Your help to fix this would be appreciated.

  Hi Debra, Maryam and Aziz (and other stakeholders)

  The problem is almost solved, I say almost because I don't like having unexplained things always happening on my computer! The solution was obtained by marketing the Narrator function and use of inputs keyboard known to explore what was going on behind the BSOD (BlackScreenOfDeath) so that I now have the monitor works in glorious mode of 1920 x 1200.

  The solution actually came from my eldest son, when he asked if there was anything on the Toshiba TV (the other feed on the Radeon 4890). Yes, you have guessed the TV screen showed a perfect desktop but at a slightly lower resolution.

  Using Clone installation I got office showing on the Hannspree in seconds and, after a bit of investigation, I found that Windows 7/Asus Radeon or some another gremlin has decided that the main screen was my TV and that the Hannspree Monitor 2? -I don't know how this can happen.

  Suffice it to say that once I told Windows 7 that no. 2 was in fact my main monitor I could turn off the installation of clone and reset the Hannspree to its native 1920 x 1200 resolution, everything I want to do now is to say the 'system' that the Hannspree is main and monitor no. 1, but if I can't then I can live with n ° 2 - lol.

  Thank you very much for your efforts and I hope that it can match someone elses knowledge of the vagaries of Windows 7.

  Best wishes

• COM3 showing in Device Manager but not in the list of printer port

  I have a Datamax Allegoro printer that uses a USB series converter. The poster converter as installed correctly (in devices and Device Manager) and received COM3.

  When I go to change the player of the printer to use the COM3 port, it is not in the list. How can I get the COM port appears in the list of printer ports?

  Note: this port was already there, but anyway when I was working on some of the settings (I changed the adapter to use COM1 temporarily as a test, then when I went to change it back, it was gone). I tried to uninstall the driver for the adapter and then re-install again, it did not work.

  Thank you.

  Use system restore to go back to an earlier date at the beginning of the problem. To run system restore, click Start-> programs-> Accessories-> System Tools-> system restore. Click on the box that says show more restore points.

  Good luck.

• Satellite C650-1CR - no webcam showing in Device Manager

  Hello

  I apologize if this question has already been posted. I have a Satellite C650-1CR; PSC08E-029001EN part number; Serial number 7A370192Q. Windows 7 64-bit operating system.

  The webcam, which has worked before, does not now in any program. In MSN it says I have no webcam; in Toshiba Face Recognition, he says camera failed to initialize. I have nothing to this fact - it has just stopped working. If I click on the Toshiba web camera application in the utilities section, nothing happens. The camera does not appear in Device Manager - there is no device images shown.

  I read through the advice here and you have downloaded the driver here, but that does not open. He goes as far as the extraction of the file, but then it will not run or open. I have the latest BIOS (update from Toshiba a couple of days). If I can avoid it, I don't really want to use the recovery disk I have many other things on my laptop that I don't want to lose.

  Any advice or help would be really appreciated. My son just moved to Australia, and it would be great for me to be able to use the webcam. I hope I gave enough information on the laptop and the problem.

  Thanks in advance for any help.
  Linda

  Hey Buddy,

  So if there is no webcam listed in Device Manager, you must check the installed programs in Control Panel > uninstall a program. Usually the webcam software should be in there and if yes remove it. Then, restart your computer.

  To remove all also run a registry cleaner like CCleaner which can remove old registry keys. It s freeware tool is therefore no problem to find using Google. After that you have to reboot your laptop again and then install the latest webcam software from the official page of Toshiba.

  Even after restart and you should be able to use the webcam again. Can you confirm this?

• How many network adapters should I showing in Device Manager?

  I have a connection to another pc at home wireless, NICs (2) listed in the Manager of devices Belkin Wireless USB adapter is one, why I ordo I need each other is NVIDIA nforce 10/100 Mbps Ethernet?

  It seems that your computer has both a wired (10 / 100 Mbps) card (adapter) and a wireless adapter.

  You don't need to have both of them enabled (you have to activate one of them).

  Your wired connection will probably be more Rapids (100 Mbps) as your wireless connection. It will also not be subject to intervention by your neighbors.

  Wireless connections are convenient for portability, but may suffer interference from your neighbor's wireless connections, and/or have degraded performance according to the distance and obstacles that esist between your computer and your wireless router.

  If your computer is a desktop computer, you can consider using the wired adapter and the deactivation of the wireless card.

  If your computer is portable (for example, a laptop computer), then you can use the adapter (activate) the wireless and disable the wired (Ethernet) adapter.

  ACPI-> Advanced Configuration and Power Interface
  ACPI defines hardware and software interfaces that allow focus on the OS configuration and power management to enumerate and configure motherboard devices.
  For example: ACPI is necessary for the standby and hibernation mode.

  Now your question; the new BIOS has been updated and configured to using VISTA.
  It seems that VISTA was not compatible with the previous version of BIOS because the ACPI interface. Now you can install Vista on the laptop, but it seems that you need a driver. Possibly new chipset driver version might help. But as you probably know, the drivers are not available at this time. Unfortunately

• Portege M200 - device unknown in Device Manager

  I did a clean install of Windows XP on my toshiba portege m200 (Tablet). I have most of the devices drivers installed, but there is one that I can't understand. The device manager says I have an "unknown device" on my "Intel 82801 dbm lpc interface controller.

  To resolve this issue go to the device, right click on the unknown device, Manager and then select set to update driver.
  When the Hardware Update Wizard appears, select the advanced option.
  From the next window, select the 'don't search. I will choose the driver' option
  Now, go to the Intel announcement and select good "82801DBM LPC Interface Controller - 24CC.
  Click OK and now it should work.

  Also, be sure you have all the drivers installed from Toshiba Web site:
