• my family vista Device Manager premium is empty!

  Hi This is my first post on this forum.

  Juice IV noticed that my device manager is also empty, its does not do anything, I'm not sure if this has anything to do with a new all in one printer I recently installed, in fact its how I discovered the problem, the scanner driver software refused to install each time I try. also I can't play games when I started with the game in the drive, it says "cannot locate the cd-rom" "Please insert the right CD, select ok and restart the application." This happened for a few weeks now. I googled many fixs to this problem. I also have a lot of programs on my laptop that would be difficult to replace so I want to keep a full reinstall as a last resort.

  It's driving me crazy to this stage and id love to get it repaired.

  Please can someone help me with this?

  best regards steve

  Hi im juice you all informing them that I had to reinstal vista on my laptop unfortunately, a mechanic called registry registry cleaner had caused damage in my registry. I had tried all the points that I have asked or told to do. I have also problems with other programs crashing etc...

  Since then reinstall it my computer worked perfectly.

  I really didn't want to do a reinstal, but the cause of the damage was too severe.

• Device Manager page can not be displayed.

  I'm not able to see the devices and the page can not be displayed in the Device Manager.

  This is the error message you get:

  MMC cannot open the file C:\WINDOWS\system32\devmgmt.msc.

  It is perhaps because the file does not exist, is not the MMC, or was created by a later version of MMC. Perhaps it is also because you don't have sufficient access to the file.

  If so, see http://support.microsoft.com/kb/914231

• Number with the Device Manager appears as empty.

  We went from XP to Windows 7 forum>

  As you may have read in the title, my device manager is empty. Nothing, absolutely nothing is in it.

  Lately, my computer shows this message

  I said to uninstall my drivers in Device Manager", but I found this to be empty.

  Referring to this thread: http://helpdeskgeek.com/windows-xp-tips/device-manager-empty-or-blank

  

  I followed ALL the steps and the steps are already finished!

  Plug-and-Play is already set to automatic,

  

  all services are enabled,

  

  and "everyone, system and RIGHTS of the OWNER" are already there with verified correct variations.

  

  I have no idea what to do now.

  I have dozens of programs purchased on my computer such as Photoshop, Illustrator, FRAPS and a very broad portfolio of my work of graphic design and progress over 2 years.

  Running on Windows 7 Home Premium, with an AMD A6 - 3420 M with Radeon (TM) HD Graphics 1.50 GHz APU

  I've had this computer for 2 years and it was Symantec's Norton running on it.

  I can't really afford to lose all my work and programs, so if anyone can help, it would save my life. Right now I can't provide customers and I am short on time!

  Thank you very much

  Kade-

  You may or may not have checked the following (the screenshots you have included does not show one way or the other).

  1. in the Configuration System (msconfig), you should look at the tab "Services", not the "Startup" tab  However, do not have a lot of confidence in the suggestion to "allow all services" and especially not non Microsoft services, for any reason, previously disabled.

  2. for what is permissions for registry Enum key, your screenshot shows only permissions for "Everyone".  Have you also checked the permissions of the 'System' and 'Advanced' for all screen everyone and system?  Did you get any error messages when you tried to change the permissions, such as the following:

  

  What happened to your system recently - power surge/failure, installed new software or updates, used a system tuner or register cleaner, etc.?

  It is quite possible that Norton herself - or malware - can be at the origin of this problem.  I suggest to first temporarily disable Norton and then redo the steps of registry key permissions.  You can do it in Mode without fail and go into Services and stop the Norton services that may still be running.

  If disable Norton and reset the permissions does not help you, if you did not recently, download, install, update and run these two free programs.

  MalwareBytes AntiMalware

  SUPERAntiSpyware

  Use the free version, not the free trials of "pro" versions  Pay attention during installation uncheck any prechecked boxes that would install some additional third-party programs.

  Do not run the scans at the same time.  Each scan will take a while.  Start one and go do a non-it chore.  Once the scan is finished, leave the program to deal with anything it finds.

  Once done, you can keep or uninstall programs, or both.  If you keep SAS, I suggest to change its default setting does NOT automatically when Windows starts.

• White Win 7 Device Manager screen

  My HP 6v6t laptop running Win 7 Home Premium.  Wireless network works OK, but the network profiles disappeared.  Checking further, called from Control Panel Device Manager page is empty.  Otherwise machine works OK although I'm unable to find a path in network settings: IP, DHCP, etc.  I'm guessing that fix might restore or allow me to establish new wireless networks profiles, Device Manager.

• Device Manager Catagory says "Unknown" instead of "USB controllers"

  

  I have this in my device manager - all my USB devices work OK.

  More I-

  

  It's my network page, but my network connection works OK.

  How can I fix it?

  Dean

  Hi Dean,

  I understand that your USB drives and internet connection works properly but it does not appear correctly in the Device Manager page and the network as appropriate.

  This problem could occur if the drivers were not properly installed or was unable to configure. As a Reader USB usually works if the default driver/generic drivers are present in the system. But as you rightly mentioned that gets listed under USB controllers.

  To better understand the issue, please send us the following information:

  1. What is the brand and model of the computer?
  2. When this problem started?
  3. You did it all changes to the computer before this problem?

  I suggest you follow these steps and see if it works:

  Run the System File Checker

  File system check to determine if the problems you encounter on your computer are caused by one or more system files.

  You can read the following Microsoft article to repair corrupted using SFC tool files. Use the System File Checker tool to repair missing or corrupted system files

  Reference: http://support.Microsoft.com/kb/929833/en-us

  Uninstall device drivers

  1. Press the Windows key + R
  2. Type devmgmt.msc
  3. Right-click on each device that is listed under the category unknown
  4. Uninstall each device and restart the computer

  After reboot, Windows will automatically install the device driver, and you should see the device listed in the appropriate category.
