Drivers No Longer Visible In Device Manager

Feb 12, 2012

I have recently bought a native instruments kontrol S2 (it's a DJ controller). I have downloaded the drivers (it connects to PC via a usb 2.0 port) updated my mother board and chipset drivers However after different periods of time the controller freezes and I get a message saying ' usb device not recognised' also when I open device manager the drivers are no longer visible. If I restart the controller it works fine for a while (can be anything from a few minutes to a couple of hours).

My PC is HP P6780-uk
2.8 ghz
4 RAM
AMD phenom 11 4 core
Windows 7 64 bit

Samsung R580 Bluetooth No Longer In Device Manager

Jun 16, 2012

I've had this computer for a few years now and have never had a problem using the bluetooth to connect to my phone until now.

When I tried to first open BTTray.exe I got an error and while trying to fix that I noticed that my bluetooth chip was no longer in my device manager, any ideas on how to fix this?

Admin's Account No Longer Visible For Log-in

Feb 2, 2013

I'm not sure what happened, but this is a new one for me. I was using my mother's laptop and decided to create a new user account for myself. I thought this would be a way of avoiding her complaints and worries of me "messing something up" on her account, i.e., trying to improve her usage of the computer. That's a story for another day. After logging out of my account, I went to log back into hers and found the icon for my account and a blank "other user" icon. I attempted to enter her username (she had no password, at least not that she recalls) but the account pic that shows up in User Accounts doesn't show up and I was unable to log back into her account. I've tried changing my account status and hers, but nothing works.

HDD No Longer Visible In Windows 7 After A Clean?

Sep 17, 2012

Posting this in this forum in case the previous one I had it in was incorrectI did my first home built computer a few weeks ago and finally got around to making my SSD my boot drive (was dormant before and I had a HDD running Windows/programs).I did a clean on the HDD (via diskpart) and then installed Win 7 64 bit on my SSDEverything worked well on that front.However, now when I try to find my wiped HDD in Windows, it can't find it. I look in my BIOS and it finds it, but it's not showing up in the boot selection options (boot selection options are only my SSD, DVD-ROM and USB drives).My goal is to have my boot drive as my SSD and then the rest of my programs on the HDD.[CODE]

Cannot Connect To Internet - Icon No Longer Visible On System Tray

Jan 9, 2012

I have an HP Desktop computer and I cannot connect to the internet. The problem started with my mouse not working well then my keyboard so we replaced them (that was a month ago). Then strange thing started to happen, a ticking sound started to sound every few minutes. Apart from that, the computer seems well and functions properly. Then one day when I tried to turn it on, the screen looks different. I am referring to what I usually see on my screen whenever I turn it on. My pc is running on windows 7 but right now it looks like its on XP. Plus I cannot connect to the internet. The icon is no longer on the systems tray and when I tried to do the following:

System restore
Network troubleshooting

It wont allow me, when I do system restore it will say A volume shadow copy service component encountered an unexpected error. Check the application event log for more information (0x80042302).

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.

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?

No Bluetooth On Device Manager

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.
