Network Adapter Not Showing On Device Manager

Nov 4, 2011

Yesterday I got my friend to download windows 7 on my mac via bootcamp. I got it back today and I tried my wireless at home but didn't work. So I tried LAN line as well, which didn't work either. I went through few sites, they all told me to go on device manager and update my drives. The problem is that i can't find either modem or network adapter on my device manager.

Wireless Mouse Showing Code 10 In Device Manager Window?

Apr 30, 2012

I got this PC 3 weeks ago. For two days now Several of my devices have a Code 10 on start up. For instance my mouse in the Device Manager window has a code 10 and will not work until I use the trouble shooter and it re-installs the driver. I have tried updating the USB drivers as many recommend but there were no updates. I tried Microsoft's fix it, and it was not fixed.

Acer Aspire One D255E Wireless Card Not Showing In Device Manager

Jan 25, 2013

HeI am at wits end here trying to figure out how to fix this pc. A friend came to me with the Acer Aspire One D255E with a wireless internet issue. The PC is Running Windows 7 Starter 32-bit. I immediately thought "well there must be a switch that she turned off" There is no switch on the computer for the wireless card. I thought "well there must be a driver issue, Ill go to the device manager and update the driver for it". Then when I got to the device manager... Nothing shows up for a wireless lan card even existing in the laptop, but I know it does, because A) It's a "net Book" B) she was using the internet last week. So, I thought maybe it's not showing up because thee computer needs the drivers for it first, which is unusual, but since its windows 7 starter I thought it needed a kick in the rear to get it goin. So i downloaded all the drivers for the PC using a different computer, and installed the different drivers to see which one would work. Well none of them worked, and now im sitting here scratching my head on what to do next. I have scoured the web and seen a few other people with issues like this.

Drivers No Longer Visible In Device Manager

Feb 12, 2012

I have recently bought a native instruments kontrol S2 (it's a DJ controller).

If I restart the controller it works fine for a while (can be anything from a few minutes to a couple of hours).

Missing Base System Device And Coprocessor For HP Pavillion?

Feb 25, 2011

I am missing three drivers in my device manager. They are listed under other drivers and when I look at the properties there is no information given as to what its for.The first two say base system device and the third one says coprocessor. None of them can be updated from the manager because it cannot find the drivers online. I believe the first two have to do with nvidea but everytime I try to download the driver it does not work. I have no idea if I am even on the right path. This is the last issue I am having from my windows 7

Cannot Get Device Manager To Uninstall Drivers For Mobile Dongle

Oct 5, 2012

I am having trouble getting my vodaphone dongle for internet access on the road installed. My PC refuses to install the drivers properly. It worked fine but it has been about 9 months since I last used it. I have made sure I have the latest drivers downloaded from vodaphone and when I try the dongle in my sons laptop it installs and works fine. I thought I would uninstall the driver from device manager but when I try to do this it just sits there for hours. I have to end up closing device manager down using task manager. I am running Windows 7 on an HP G62 Notebook.

Coprocessor, Aspire 7530g Drivers

Dec 6, 2009

As I was exploring my Aspire 7530g I stumbled upon an uninstalled component, the "coprocessor".

Device Status:

"The drivers for this device are not installed. (Code 28).."

I did my research and found a mass variety of solutions.

I opened Everest and saught out the unit myself.

nVIDIA MCP77 - Management Unit

I asked my good friend google for some drivers and how to's.

I downloaded and installed the latest drivers to my Nvidia 9400m.

Alas, the effort led me to the same climax of me having an uninstalled CoProcessor.

Am I supposed to install M-board drivers, suggestions?

Device Manager Reports Unknown Device & Explorer Crash

Aug 1, 2009

How do i figure out what driver or even component windows wants software for when in the device manager under other devices it lists an unknown device and windows update cannot find anything.

Oh and is it appropriate for me to use this topic to ask another question regarding explorer.exe as while i am inside a folder i delete (by choosing delete from the context menu in the tree view) while inside that folder on this particular laptop PC explorer. always crashes, collect information, sends it and restarts explorer. I have not experienced this problem on any other pc running any version of windows 7, oh and the same happened with build 7264 x32 and the current install of build 7600 x64.

Windows 7 Usb Camera Device Shows Up In Device Manager But Not Computer

May 31, 2012

Have recently purchased a small usb inspection snake camera with led light and when testing it plugged it into two desktops computers (one xp pro not sure of the other as it was a network work computer) It automatically loaded the drivers and brought up a screen automatically with the realtime image.(no driver disc came with it). However plugging into my windows 7 64bit sony laptop it signals a connection beep, loaded drivers automatically but wouldn't open or show up on my computer disc manager as an external usb source to click on. It does however show up on device manager as a usb camera and when I unplug and replug in it disappears and reappears so I know I have the right camera (not the lap top webcam inbuilt one that shows USB 2 Camera). Have tried updating drivers automatically and uninstalling it etc. Need it to work on the lap top so it can act as the movable screen for it?

Windows 7 Fonts Not Showing In Font Manager

May 3, 2012

I am trying to install 32 barcode fonts (type .ttf) using a batch file. Everything that I have read says that you should just be able to copy the font to C:windowsfonts and then add the appropriate value to the registry at HKLMSoftwareMicrosoftWindows NTCurrentVersionFonts. My batch file does both of these things, however the fonts still do not show up in the font manager (or applications). They do show up if I browse to the fonts folder using cmd so I know they are where they should be. Is there something that I am missing here? These fonts need to be installed on every computer at my company so manually installing them isn't really an option.

Windows 7 Task Manager Not Showing Apps Running?

Sep 27, 2011

Windows 7 Premium 64 bit's Task Manager used to show a bar with pplications/Processes etc., with lists below making it possible to "end-now" some apps and stop some processes at least for a while to save on CPU/Memory usage. There was also provision by a menu bar at the top of Task Manager window to shut down pc etc., from within the task manager.Presently my Windows 7 Premium 64 bit's Task Manager shows only what looks like a list of processes (Not Applications) topped by a head-bar having Name/PID/Description/Status/Group and a selectable button at the bottom right for Services.(I could have uploaded ascreen if this Ask Your Question Form had provided for attachments!).I suspect this change in Task Manager came after some new installs - Windows Updates etc.

Nov 3, 2011

I have my Dell N4010 Inspiron 14R laptop/notebook with the OS of windows 7 32bit Ultimate.

My bluetooth was previously working fine with the driver Dell wireless 365 Bluetooth Driver 6.2.1.100 A00 win 32/64bit R273580. I notice that this past days when i connect my N6120c phone via bluetooth, my laptop didn't have any reaction, when i see my system tray no bluetooth icon was presented, previously there it is. So i manually run the bluetooth through BTTray.exe from CProgram FilesWIDCOMMBluetooth Software, but my laptop didn't react to it. So i look at the device manager and there was no trace of bluetooth, previously there was a Peripheral Bluetooth. So i manually re-install the driver and then its stuck on this page, Activate Bluetooth using Wireless Switch, on the lower right it say Cancel Installation.

I recently installed new software (2 weeks ago) with no problems, until now. I am using a HP Pavilion g w/ Windows 7. I've tried reinstalling the software, but the computer just won't recognize the device.

Should the Ports tree be there? I've already restarted my computer and entered the BIOS menu, and it said my USB Ports were enabled.I've already been to the Registry Editor in Blah-Blah key and entered "3" (was already that way).My ports are just gone. What should I do?
