This morning I tried to open a photo in the Photos app and got a File system error. When I tried to open Start, it didn't open, tried Notification bar - same. No big deal, I need to reboot my laptop (this have happened before). During the reboot the keyboard remained lit up in green color, after the reboot, at the PIN screen the buttons didn't work and the backlight was not cycling through colors. I used the on screen keyboard to enter the PIN, in Device Manager the keyboard group is missing. Mouse works, tried rebooting (power button), restart from Start menu, Shut down, Find legacy devices in Device Manager, fix registry errors - all of this failed. I have a wireless keyboard, that I've yet to test if it's working or not (needs to be charged). My laptop is Asus ROG GL553VE.

What Version of Windows is this?  Win 10 64?


File System error indicates a file on the hard drive is not readable.  Could be that the drive is failing or a memory error or some transient fault.  Let's look at the event recorder and see if it gives a clue:


1. Please download the Event Viewer Tool by Vino Rosso
and save it to your Desktop:
2. Right-click VEW.exe and Run AS Administrator
3. Under 'Select log to query', select:

* System

* Application
4. Under 'Select type to list', select:
* Error
* Warning

Then use the 'Number of events' as follows:

1. Click the radio button for 'Number of events'
Type 20 in the 1 to 20 box
Then click the Run button and wait.
Notepad will open with the output log.

Please copy and paste the Output log into your next reply


We can look at the hard drive with Speccy:


Get the free version of Speccy:


(Look in the upper right for the Download
Latest Version button  - Do NOT press the large Start Download button on the upper left!)  
Download, Save and Install it.  Tell it you do not need CCLEANER.    Run Speccy.  When it finishes (the little icon in the bottom left will stop moving),
File, Save as Text File,  (to your desktop) note the name it gives. OK.  Open the file in notepad and delete the line that gives the serial number of your Operating System.  
(It will be near the top,  10-20  lines down.) Save the file.  Attach the file to your next post.  Attaching the log is the best option as it is too big for the forum.  Attaching is a multi step process.

First click on More Reply Options
Then scroll down to where you see
Choose File and click on it.  Point it at the file and hit Open.
Now click on Attach this file.


If the hard drive just lost a sector or two then you can sometimes fix it by opening an elevated Command Prompt:


Win 7: Start, All Programs, Accessories then right click on Command Prompt and Run as Administrator
Win 8: http://www.eightforu...indows-8-a.html
win 10: http://www.howtogeek...-in-windows-10/

or Search for

cmd and when it finds Command Prompt, right click on it and Run As Admin.



chkdsk  /r  C:



hit Enter

It will say it can't do it now and ask if you want to schedule it for the next reboot.


Tell it Y


Reboot and the system should start checking the drive.  This can take hours depending on the drive type and size and the speed of your PC.


Once it finishes it should start windows.


Go back into an Elevated Command Prompt and type:

DISM  /Online  /Cleanup-Image  /RestoreHealth

This will take a while to complete.  Once the prompt returns:

sfc  /scannow

This will also take a few minutes.  

When it finishes it will say one of the following:

Windows did not find any integrity violations (a good thing)
Windows Resource Protection found corrupt files and repaired them (a good thing)
Windows Resource Protection found corrupt files but was unable to fix some (or all) of them (not a good thing)

If you get the last result then:


findstr  /c:"[SR]"  \windows\logs\cbs\cbs.log  >  \windows\logs\cbs\junk.txt


followed by:

notepad \windows\logs\cbs\junk.txt


 Copy the text from notepad and paste it into a reply.


Let's check if some keyboard services are running:


From the elevated Command Prompt:

sc query kbdclass

Normally looks like this:


SERVICE_NAME: kbdclass
        TYPE               : 1  KERNEL_DRIVER
        STATE              : 4  RUNNING
                                (STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN)
        WIN32_EXIT_CODE    : 0  (0x0)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0


sc query kbdhid
        TYPE               : 1  KERNEL_DRIVER
        STATE              : 4  RUNNING
                                (STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN)
        WIN32_EXIT_CODE    : 0  (0x0)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0


If either says it is not running (bold in the above) see if it will start by typing:

sc start kbdclass


sc start kbdhid

Report exact text of any errors.


There is a driver available for Win 10 64.  It controls the keyboard lights and some hotkeys.  Probably won't help but wouldn't hurt to try:




This is a zip so download and save then go to your download folder and right click and Extract All, Extract.  Find Setup.exe and right click and Run As Admin.  Reboot.


Finally there is a file called keyboard.inf  see if you can open it in notepad:


From an elevated Command Prompt type:

notepad c:\windows\inf\keyboard.inf

Once it opens  do  Ctrl + a then  Ctrl + c which will select all of the text and copy it then move to a reply and Ctrl + v.
