Tip & How-To about Microsoft Windows XP Professional

Windows Device manager conflict

Fully working Device will have no symbol on the respective device so as far as windows is concerned there is no conflict. However if the BIOS shows a Device Conflict Error with the PCI bus you will have a conflict in Windows.




  • A black exclamation point (!) on a yellow field indicates the device is in a problem state. Note that a device that is in a problem state can be functioning.


  • A red "X" indicates a disabled device. A disabled device is a device that is physically present in the computer and is consuming resources, but does not have a protected-mode driver loaded.

  • A blue "i" on a white field on a device resource in Computer properties indicates that the Use Automatic Settings feature is not selected for the device and that the resource was manually selected. Note that this does not indicate a problem or disabled state.
  • A green question mark "?" in Device Manager means that a compatible driver for this device is installed, indicating the possibility that all of the functionality may not be available. Note that this applies only to Windows Millennium Edition (Me).
NOTE: Some sound cards and video adapters do not report all of the resources they are using to Windows. This can cause Device Manager to show only one device in conflict, or no conflicts at all. This can be verified by disabling the sound card, or by using the standard VGA video driver to see if the conflict is resolved. Note that this is a known problem with S3 video adapters and 16-bit Sound Blaster sound cards, or those sound cards that are using Sound Blaster emulation for Sound Blaster compatibility

I would run chkdsk/f on your hdd as errors like this can be caused by system file issues. Go to my computer, right click on drive C and choose properties than tools and then click Check Now. After that run ASC from iobit, a free registry cleaner that actually works!

Dell e520 running Vista fully updated has no sound


Depending on the audio hardware configuration, you may have a hardware conflict.

If you have an expansion sound card (Usually a Soundblaster card in the slots below the video card) then you need to ensure the integrated audio in BIOS is DISABLED.

If you have no expansion card, then ensure the BIOS Audio device is ENABLED.

If integrated and no device found in Device Manager, turn it off in BIOS, reboot then reenable it and see if it is detected.

If issue still continues, try flashing the BIOS and see if that resolves. If no change, you may end up getting an expansion audio card or resintalling Windows to resolve.

Same BS wifi problem as everyone else


Have you tried restoring the computer back a couple of days to see if that clears up the hardware hiccup? You can also go to device manager and uninstall the device and delete the drivers. Turn the laptop off, take the wireless card out. Start the laptop back up and boot it fully....After a few, shut down again. Install the wireless card and restart the laptop. When asked to install the drivers for new device found, say ok, make sure you are online with an ethernet line so windows can go online and load the newest drivers unless you have them on your C drive already.

need to get audio device back into computer


First you should check to see if the audio card is in the Device Manager. If not, try shutting down, unplugging power to PC open case (only if your comfortable doing so), physically remove the sound card and re-fasten it in the respective slot. Reconnect power and go into the BIOS. Once in the BIOS, get to the section of integrated peripherals, and disable the on-board audio. Save and exit, then let it boot up. If you get no "Found New Hardware", open the device manager and see if the card appears in the list. At this time if there is a question mark or an exclamation point, you have either a hardware conflict or an unknown device. If you don't have either of the symbols next to the audio card in the list, try opening your audio properties again and see if the card has returned to the software. If the device is not there, but is on the list in Device Manager, try re-installing the software it came with. If you have the other issues with the symbols and re-installing does not work, there may be something more than what may be the obvious.
