No Devices In Device Manager? USB And Sound Don't Work?
Apr 4, 2006
I had to reinstall windows XP because my OS would not load and I got all the drivers reinstalled, diagnostic ran smooth and everything came up working ok etc but my device manager won't recognize anything! The compy says my audio mixers are not there, my USB devices are not working, hardware wizard is not responding, microsoft updates are not working, Dell's driver downloads are calling out for something that isn't there and I really need this fixed ASAP so I can get to my external HD.

I have XP and when I open my device manager, no devices are shown at all. This is not corrected by the usual microsoft help (i.e set services plug/play to automatic).

I changed the system boot in "MsConfig" and now my sound, scanner and my printer don't work. I looked at the device manager to see if there was an error with the soundcard or something, but all devices have vanished from the device manager. I just tried to connect my ipod to the computer, and it said the software can't communicate with the ipod.

All of a sudden, the imaging devices attached to a computer with Windows XP Pro SP2 are showing up under the Unknown category in the Device Manager. The
devices are listed correctly by their names under Unknown, but the software won't communicate with them.Windows can see the devices, but it does not know what type of devices they are. It is only the imaging devices. One is a Canon 4200F Canoscan scanner, the other is a Sony Camcorder, and the third is a hardware capture device (Pinnacle Moviebox). The Canon scanner is a USB 2.0 device, while the other two are attached through firewire ports.

There are a few things that contributed to the leadup to me losing my Device Manager and sound. First, about 3 weeks ago, I bought 2 sticks of Mushkin EM3200 DDR RAM (two 1GB sticks; 2GB total). Installed it, and it disagreed with my board in a big way (apparently it was the voltages or timings). I managed to get as far as "Verifying DMI Pool Data..." before I got one of two error messages: "NTLDR is missing. Press Ctrl+Alt+Del to restart." or "Windows failed to load because the System32 folder is corrupt or missing." In each case, I popped in my Windows XP disc and fixed the boot record from the recovery console (I did not restore the MBR), and it booted right in.
At the time, Windows booted up just fine, but lately I've been having some funky problems. I've got one SATA drive (partitioned into two) which is my boot drive and one IDE drive that I just use for storage. Sometimes, with my IDE drive plugged in on boot, I can't get Windows to load by any means. Sometimes it boots just fine. When it boots fine, and I go into "My Computer" (either via the Start Menu or the icon on the desktop) it takes about 20-30 seconds to actually display anything (I get either the flashlight-over-folder animation or it just doesn't load). With my IDE drive unplugged, I get no such issues.
As well, the first couple of times I restored the boot record, I had no issues with sound at all. Then suddenly Windows started saying I had no sound device (my volume icon had disappeared, and the "Sounds and Audio Devices" menu in the Control Panel showed no output/playback device) although I clearly do have one. The weird thing is, I still got sound. Then I updated my sound card drivers (it's onboard sound; Realtek AC'97, pretty standard fare) and lost sound completely. All I get now is motherboard/PC speaker beeps. So I attempted to check the Device Manager to see if maybe there was just a device conflict. I say attempted because my Device Manager was completely blank. And I mean completely. All it showed was the title bar, menu buttons, and a white page. Nothing else. Zip.Just ran out to work and got an Audigy for $30 thinking it may just have been my onboard sound kicking the bucket. Installed it, booted up and tried to install the drivers. The driver installation program detected no Audigy in my machine (and I thought it wouldn't because Windows didn't pop up with the little "Found New Hardware Wizard" when I booted).

I have lost my sound. The sounds icon in control panel say " no audio devices" AND the sound tab shows all listed devices as working porperly. I have deleted an sound object that allows it in device manager and allowed XP to load wht it will. I still have no sound. I checked for sound services in services and they are started as well.If I load Knoppix and test, my sounds work so I am assumming it is not a hardware problem.

I had some trouble last night and today with getting rid of a virus. Now that it is gone, I am having sound problems (maybe related, maybe not). This morning, when I opened iTunes I got a message that there was no audio device detected. After trying several things, I rebooted. Magically, I could play music again. However, a short while later, I again got an error message telling me that there is no audio device found, even though it shows up in Device Manager as working properly. The problem goes away for a short time after I reboot, but returns. It is Realtek AC 97. Why won't my computer keep recognizing it? (It tried going to Realtek's site to download an update. It has updates for Windows 98, 95, etc., but not for XP. Or at least I couldn't find it.)

Running Windows XP on Emachines ET1161-07. Installed all drivers that I could find, since EMachines does not represent XP. Tried Realtek audio and HD audio, tried Intel, didn't work. Tried NVidia, as it has an NVidia motherboard. Spent too much time on this computer. Can anyone lend a hand? I know it's got something to do with Audio, as there's no audio device detected in Sounds, under Control Panel.Customer has to have computer today.

I had this problem last time when I fresh installed Windows XP Pro on my computer. I don't know the time, but it happens at least 30 days after I reinstall the OS and software. Today, my computer prompted me to install drivers for a PCI Input Device, but I haven't installed any new hardware for months. Basically, I haven't touched the inside of my computer for that long. So why is Device Manager prompting me to install this mystery device? Hardware ID shows that it is from vendor 1102, which is Creative, and I have an Audigy 1. Also, my FireWire port is Code 10, the device cannot start. So I'm thinking the mystery device is the same firewire port. But why show up as a separate device? I tried removing the devices and restarting the computer, but they return to haunt me again. The device properties for the PCI Input Device says PCI SLOT 7, AND I DONT HAVE A 7th slot! Can someone help me, please? Device manager shows my 1394 Net Adapter with a yellow exclamation, and it has code 10, device cannot start. There is an unknown device, the PCI Input Device, which doesn't allow me to install any drivers for it, yet it has the creative Vendor ID 1102. It shows itself as being PCI Slot 7.

I have a feeling that this is simply a case of some registry settings which need adding/modifying/deleting but exactly which ones and what values I do not know. No, I haven't tried re-installing XP.

A friend of mine has a 4 yr. old PC running XP Home with 128Mb of memory. He's had problems with programs aborting recently. I tried to run Device Manager to make sure there were no issues there. It briefly brought the screen up, then it went away. The same thing happened to Task Manager when I tried to see what was running and how much memory was being used. Anybody ever see this behavior before? I might try installing a memory cleaner pgm (ie. Memturbo), but I'm not sure I would even be able to get it to run. The hard drive amd memory seem to have no errors.

Last night I installed ATiTool 0.24 over my 0.25 version (stupidly). I also did a BIOS update and installed Cat6.3 and then AVIVO converter. When I rebooted, I had this new PCI device requiring a driver,but it's an unknown device and doing an auto update helped me.I can't get rid of this pesky PCI device (tried uninstalling but Windows detects it again after restart/boot-up). All my stuff is working, so I don't know where this critter came from?

My computer cannot detect any cd's in my DVD or CD drive. When I open Device Manager the CD/DVD devices have an error. This error: Windows successfully loaded the device driver for this hardware but cannot find the hardware device. (Code 41) Click Troubleshoot to start the troubleshooter for this device.When I run the DriverScan it simply doesn't even have an entry for the drives, probably since it thinks it doesn't even exist at the moment.

Anyone know how I can rename a device in device manager, (or the registry), so it doesn't show #2 after the device.I used the leadtek driver uninstall tool last night. And it removed the drivers I had for this Leadtek Deluxe tuner alright.BUT it also renamed my onboard Gigabit LAN (onboard) to #2 my scanner to #2,
and removed my Nvidia drivers for the video card.And reverted the videocard drivers to MS Nvidia drivers.I managed to fix the scanner entry by uninstalling the drivers, then rebooting and reinstalling the drivers.And I managed to fix the videocard drivers, by reinstalling the Nvidia drivers.So, yup, anyone have any idea how I can change the board LAN, so it doesnt have #2 after it? sing XP Pro SP2

I am running a WinXP SP2 machine, with a Sound Blaster Audigy 2 ZS.One day, during a Windows session, my sound just stopped working. I tried to play a song in Winamp, and got the message: "Device not found. Please select another device in configuration. Error code: 88780078." The window title was "DirectSound output v2.2.12 error".Trying to play a song in Windows Media Player yielded a simlar result: "Windows Media Player cannot play the file because there is a problem with your sound device. There might not be a sound device installed on your computer, it might be in use by another program, or it might not be functioning properly."
