Hi magjoseki738,
Can you locate the "Unknown Device" in the Device Manager and right-click the device > Properties > Details, then choose "Device Instance Path" from the drop-down menu under "Property".
What is listed?
Please see if this link works:
Unknown Device (Code 28) - All Network Drivers (Code 31)

I'm trying to fix a problem with my Dad's computer, he advised that he couldn't connect to the internet anymore. When I took a look, the Network icon in the system tray says 'Not Connected - No Connections Available'.
After alot of faffing and searching on the net, I stumbled across the Device Manager and found that all of the Network Drivers have a Code 31 error. Then I noticed below these, that there is another error for an 'Unknown Device' which has a Code 28 error. On the Details tab in Properties for the Unknown Device, the Values state '00000040' and 'CONFIGFLAG_FAILEDINSTALL'.
Everything was working fine before, please can someone point me in the right direction?
I have attempted to update the Network Drivers to no avail. Obviously I would try to update the 'Unknown Device' if I knew what an earth it was!
Thank you very much in advance.
The computer is a Dell Vostro 1015 laptop with Windows 7.

2013-05-24T18:45:31+00:00 I have the .evtx file now but need the .nfo file.
Here are the instructions again for providing the .nfo file:
Start > type msinfo32 in the "Search programs and files" box and press "Enter" > File > Save > then save as an .nfo file
Then make the resulting .nfo file available via Windows Live SkyDrive .

2013-05-25T20:20:56+00:00 There appears to be two "problem devices" (bolded):
<Category name="Problem Devices"><Data><Device><![CDATA[Not Available]]></Device><PNP_Device_ID><![CDATA[ROOT\LEGACY_DXKGFILTER\0000]]></PNP_Device_ID><Error_Code><![CDATA[The drivers for this device are not installed.]]></Error_Code></Data><Data><Device><![CDATA[PS/2 Mouse]]></Device><PNP_Device_ID><![CDATA[ACPI\PNP0F03\4&DAE4155&0]]></PNP_Device_ID><Error_Code><![CDATA[This device is not present, is not working properly, or does not have all its drivers installed.]]></Error_Code></Data>
The first one appears to be related to "DXKGFILTER**".**
Has iDisplay ever been installed?
The second one "ACPI\PNP0F03\4&DAE4155&0" may be related to a USB mouse.
Has a Microsoft USB mouse ever been attached to the computer?

Yes, I installed iDisplay, but uninstalled it. Some leftover files? Can they be removed/deleted now?
No Microsoft mouse ever installed. I am always using Logitech wireless mouse and keyboard.

What version of iDisplay was installed?
Also, does any problem device show up in Safe Mode?
