As the description states, I think that the keyboard driver was corrupted by one or more viruses back when I got infected with AV Security 2012 and ZeroAccess, among others.
However, my computer has since been declared clean after a great save by SweetTech.

I may be wrong about the virus being the cause of the problem, but I do know it's a software problem, as the keyboard will work while the computer is booting up, (long enough that I can still put it in safe mode) but as soon as Windows boots the physical keyboard becomes totally unresponsive, even in safe mode.

The On-screen keyboard still works.
I don't know whether a USB keyboard would work or not, as I don't have one.

I hve already tried different keyboards, uninstalling and reinstallng the keyboard driver normally, in safemode, and also reinstalling after rebooting the computer, but it didn't work.

The device status for the keyboard is:
This device cannot start (code 10)

Hi -
This is one of the most common error messages that you will ever get, as it means so many things
Please post a snapshot with Speccy - This way we can see a few devices that are connected -

I downloaded and ran speccy, and when I tried to go online after doing so, the computer crashed, and when it started again, I got a message saying that "windows recovered from a serious error"

The error signature is:
BCCode : 10000050 BCPI : E40C001C BCP2 : 00000000 BCP3 : BF82EBA6
BCP4 : 00000001 OSVer : 5_1_2600 SP :3_0 Product : 768_1

I've copied the error reports, but the files are too big to attatch to this post, is there somewhere else I can post them?

Can you attach them in "zip form", if you think they are too big ??

Save them and > right click on them and > Send to Zip file > then post them back here ??
Was there a Blue Screen event involved in the crash, or just a shutdown or freeze ??

Speccy has never caused me (or 99% of others a crash) so this is unusual - If you can still post it then it would help -
I was going to add another scan, but I would like to see the last result still -

Also since your last Malware removal was about 4 months ago, I cannot say what your current situation is at this time -

Thank You -

I think you have kaspersky installed on your PC.Kaspersky is known to cause issues with keyboard drivers.

Uninstall kaspersky,reinstall your keyboard driver and see if that works

good luck

Hello again, noknojon sorry for the late reply.

The crash was a spontaneous restart of the computer, no blue screen involved, thank goodness.

Second speccy post attempt successful, no errors this time.
http://speccy.piriform.com/results/VqtVPb8SpyUTZ6VX0AynPWY

I was able to upload one of the error report files,
Attached File  sysdata.zip   9.23KB   4 downloads
but the dmp file is 19.5kb after compression, :huh: so I still can't post it here.

Incidentally, windows says it cannot open the dmp file, becaus it needs to know what program created it.
Three questions:
Am I correct in assuming that this is not normal?
Which program should I use to open the file?
and lastly,
Would it be possible to split the file into smaller parts, and post them?

Thanks for the info narenxp, but I'm pretty sure Kaspersky isn't the cause of the problem because the keyboard was already not working before I installed it. (Kaspersky)
Thanks anyway, though. :thumbup2:

Okay, this is wierd.
I bought an old USB keyboard and according to windows it installed properly, but it doesn't work either, even though keyboard properties claims that "this device is working properly".

Anyway, here's the speccy snapshot of the computer that was taken with the USB keyboard connected.

Hi -
Sorry you slipped behind (add a Do Not Forget Me if it happens again) -
Please refer back to the Post #5 above by narenxp --

I bought an old USB keyboard and according to windows it installed properly. It never installed -

From your Speccy report - April 11 showing the newer (just as old) k/board never actually installed -
Antivirus
Antivirus: Enabled Company Name: Kaspersky Lab
Display Name: Kaspersky Anti-Virus Product Version:
12.0.0.374

HID Keyboard Device
Device Kind: Keyboard
Device Name: HID Keyboard
DeviceVendor: Unknown - Location:
<<- This was never installed
Location 0 <<< - - - Missing
DriverDate: 7-1-2001- Version: 5.1.2600.5512
File: C:\WINDOWS\system32\DRIVERS\kbdhid.sys
<<-Try to locate these driver files if you still have the same new k/board
File: C:\WINDOWS\system32\DRIVERS\kbdclass.sys <<- Try to locate these driver files

Did you try to disable Kaspersky (while off line) and see if there was a change ??


From the first Speccy - April 5 -
Standard 101/102-Key or Microsoft Natural PS/2 Keyboard
Device Kind: Keyboard
Device Name: Standard 101/102-Key or Microsoft Natural PS/2 Keyboard
Location: plugged into keyboard port

Driver - Date: 7-1-2001 -Version: 5.1.2600.5512 <<- Note the same driver versions and dates as above
File: C:\WINDOWS\system32\DRIVERS\i8042prt.sys <<- Location of both Driver files have changed
File: C:\WINDOWS\system32\DRIVERS\kbdclass.sys << - - - - " " " " "

Time for a New Keyboard IMO - Not a second hand one from an unknown computer -
Quick EDIT -
Are you sure the 2nd k/board was correctly plugged in, as it is not recognised -

I'm sorry for the extremely late reply, :whistle: but I had given up on getting help from here, and was trying to find help elsewere, and wasn't checking my content (and for some reason yahoo dropped the E-mail notification).

I've decided to try a repair install with XP.


before I try this,I want to back up my data on an externl harddrive, is there any danger of a virus infecting he disk I'm using for backup?

I don't think that is the best option to go for: It seldom is!

Yes, there is always the danger of infecting the backup drive if you are backing up from an infected system. You can be careful in what you chose to backup and minimise the risk that way, but there is no guarantee.

I think the best option at this stage is to un-install Kaspersky and check the result of doing that.
  • Then you may re-install Kaspersky if you wish.
You should of course check that your newly acquired second-hand USB keyboard does in fact work on another system before placing an reliance on testing with that.

I'm not sure I want to reinstall Kaspersky because the copy I have is only good for three installations, and I'm not sure if there are any left (People have been "borrowing" the disk to put it on thier computer.) <_<
I don't think Kaspersky is the problem anyway, as The keyboards quit working weeks
before installing Kaspersky. :shrug:

I've already done a repair install on Kaspersky, and that didn't work.

All of the keyboards work fine on other computers, and the keyboards also work while the computer is starting up, but as soon as Windows starts booting it's as if the keyboards aren't even plugged in. :angry:

That info goes a long way to narrowing down the source of the problem, so thank you for filling in those details.

Once Windows loads, neither USB nor PS/2 keyboards will function.

If it was only the PS/2 connected device that was having a problem, and not the USB, I would have a fair idea of what the problem might be. However, the fact that both PS/2 and USB devices are disabled, has me a little fazed and not knowing exactly where to start looking.

Give me a little time to have a think about this.
