All of a sudden the computer loses the correct files for the monitor and it falls back on the Generic non Plug and Play monitor driver that only maxes out at 1024 x 768 resolution. I proceeded to uninstalled this driver and attempted for a restart to see whether if this was just a hiccup; I believed Windows should be able to identify the. These are component drivers of the software programs you installed on your computer. To see these hidden drivers, just click on the “View” tab then check the “Show hidden devices” option. After doing this, you should see a new category labeled “Non-Plug and Play Drivers”. Get drivers and downloads for your Dell Inspiron 3442. Download and install the latest drivers, firmware and software. It displays details about the currently installed and connected Plug and Play devices. To view the Non-Plug and Play devices, from the View tab, you have to select Show hidden devices. Right click on Non-Plug and play drivers in Device Manager and select scan for hardware changes, see if is reinstalls the driver. Partmgr is not really hardware, it is a windows core service, I am not sure how to reinstall it either, but I am looking. Best 808 vst.
-->Device Manager lists the devices that are installed in the computer. By default, certain devices are not shown in the list. These hidden devices include:
Devices that have the device node (devnode) status bit DN_NO_SHOW_IN_DM set.
There is a devnode for each device on a machine and the devnodes are organized into a hierarchical Device Tree. The PnP manager creates a devnode for a device when the device is configured.
A devnode contains the device stack (the device objects for the device's drivers) and information about the device such as whether the device has been started and which drivers have registered for notification on the device.
Devices that are part of a setup class that is marked as a NoDisplayClass in the registry (for example, printers and non-PnP drivers)
Devices that were physically removed from the computer but whose registry entries were not deleted (also known as nonpresent devices).
Note
Starting with Windows 8 and Windows Server 2012, the Plug-and-Play Manager no longer creates device representations for non-PnP (legacy) devices. Thus there are no such devices to view in the Device Manager.
Note
Users should never have to view nonpresent devices because a nonpresent device should not have their attention and should not cause any problems. If a user has to view your device when it is not present, there is likely a problem with your driver design. However, during testing, a developer might have to view such devices.

Prior to Windows 8, to view nonpresent devices, you must set the environment variable DEVMGR_SHOW_NONPRESENT_DEVICES to 1 before you open Device Manager, then open Device Manager, and on the View menu, select Show hidden devices.
To permanently set the user environment variable DEVMGR_SHOW_NONPRESENT_DEVICES to 1, use the Advanced tab of the system property sheet. After you set this environment variable, run Device Manager and select Show hidden devices.
