This device cannot find enough free resources that it
can use. If you want to use this device, you will need to disable one of
the other devices on this system. (Code 12) |
Two devices have been assigned the same input/output
(I/O) ports, the same interrupt, or the same Direct Memory Access
channel (either by the BIOS, the operating system, or a combination of
the two). This error message can also appear if the BIOS did not
allocate enough resources to the device (for example, if a universal
serial bus (USB) controller does not get an interrupt from the BIOS
because of a corrupt Multiprocessor System (MPS) table).
You can use Device Manager to determine where the conflict is and
disable the conflicting device.

a bus driver erroneously creates two identically named children (bus
driver error), or when a device with a serial number is discovered in a
new location before it is removed from the old location.
Restart the computer.
On the General Properties tab of the device, click
Troubleshoot to start the troubleshooting wizard. |
| 43 |
Windows has stopped this device because it has reported
problems. (Code 43) |

| 45 |
Currently, this hardware device is not connected to the
computer. (Code 45).
To fix this problem, reconnect this hardware device to the computer. |
The device is not present or was previously attached to
the computer.
If Device Manager is started with the environment variable
DEVMGR_SHOW_NONPRESENT_DEVICES set to 1 (which means show these
devices), then any previously attached (NONPRESENT) devices are
displayed in the device list and assigned this error code. For more
information about using Device Manager to show previously attached
devices, see "Managing
Devices" in this book.
No resolution is necessary. |
| 46 |
Windows cannot gain access to this hardware device
because the operating system is in the process of shutting down (Code
46).
The hardware device should work correctly next time you start your
computer. |
The device is not available because the system is
shutting down.
This error code is only set when Driver Verifier is enabled and all
applications have already been shut down.
No resolution is necessary. |
| 47 |
Windows cannot use this hardware device because it has
been prepared for "safe removal", but it has not been removed from the
computer (Code 47).
To fix this problem, unplug this device from your computer and then
plug it in again. |
The device has been prepared for ejection.
This error code occurs only if the user used the Safe Removal
application to prepare the device for removal, or pressed a physical
eject button. Restarting the computer brings the device online if the
user does not want to eject from the dock.
Unplug the device, and then plug it in again. Alternately, restart
the computer to make the device available.
On the General Properties tab of the device, click
Troubleshoot to start the troubleshooting wizard. |
| 48 |
The software for this device has been blocked from
starting because it is known to have problems with Windows. Contact the
hardware vendor for a new driver. (Code 48) |
Obtain and install a new or updated driver from the
hardware vendor.
On the General Properties tab of the device, click
Troubleshoot to start the troubleshooting wizard. |
| 49 |
Windows cannot start new hardware devices because the
system hive is too large (exceeds the Registry Size Limit). (Code 49)
To fix this problem, you should first try uninstalling any hardware
devices that you are no longer using. If that doesn't solve the problem,
then you will have to reinstall Windows. |
The system hive has exceeded its maximum size and new
devices cannot work until the size is reduced. The system hive is
a permanent part of the registry associated with a set of files
containing information related to the configuration of the computer on
which the operating system is installed. Configured items include
applications, user preferences, devices, and so on. The problem might be
specific devices that are no longer attached to the computer but are
still listed in the system hive.
The solution is as stated in the Device Manager error code text. To
view devices that are no longer attached to the computer, set the
environment variable DEVMGR_SHOW_NONPRESENT_DEVICES to 1. Then run
Device Manager to view, uninstall, and reinstall these devices. For more
information about using Device Manager to show previously attached (NONPRESENT)
devices, see "Managing
Devices" in this book. |
