Hi,

I've just upgraded & bought a new tower consisting of;

AMD 3500+ CPU
GA-K8NF-9 Mother Board
1gig Kingmax DDR400 RAM
Winfast PX6600GT TDH Extreme Version Graphics Card
200gig Seagate SATA hard disk
CD Rom etc etc

I've kept my old Honeywell (FCC ID:AQ6-92K15) keyboard & MX1000 Logitech Mouse. I have XP Home & have used this disk to reinstall Windows after a format heaps of times on the older machine without anything like this problem.

After formatting the new drive & reinstalling XP, my keyboard won't work. If I go to device manager & unistall the keyboard then reboot it works, but if I then reboot again without uninstalling the keyboard it won't work?? :eek:

I have tried this many times & the result is always the same, uninstall & reboot...fine, just reboot....NOT FINE! :mad:

Device manager has a yellow exclamation mark & "right click/properties" is giving me an error stating it couldn't be started & giving me a code 10 error, I've trouble shooted in device manager but to no avail. I've searched the Web without success. I've deleted the keyboard drivers out of C:\Windows\Inf & I've tried using another keyboard....same results.

Would there be anyone who may be able to help, anything is appreciated, I'm at the stage where I will try any suggestions.

Thanks in advance

Short recap and practical next steps for the symptom reported (keyboard works after you uninstall it in Device Manager but fails on the next normal boot). This combination — new GA‑K8NF‑9 board + Windows XP reinstall + intermittent keyboard enumeration — commonly comes down to three things: BIOS USB/legacy settings and BIOS quirks on that Gigabyte board, driver/filter conflicts inside Windows (keyboard class filters), or missing/incorrect chipset/USB drivers. The GA‑K8NF‑9 support/manual shows the BIOS options and driver downloads you should check first. (See the GA‑K8NF‑9 support/manual and downloads.)
(Gigabyte manual and downloads: https://www.gigabyte.com/Motherboard/GA-K8NF-9-rev-1x/support)

Concrete troubleshooting checklist (safe, in-order):

  1. Back up the registry first. Open Regedit and inspect the keyboard class key:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}

    If you see an UpperFilters/LowerFilters value that contains extra entries (leftover filter drivers), remove anything except the normal kbdclass entry — only after exporting a registry backup. This fix is a documented resolution for keyboard driver/filter conflicts. (Microsoft guidance and community examples.)
    (Notes on keyboard class filters: https://learn.microsoft.com/en-us/answers/questions/733453d1-3d54-4a21-8f40-0d69068b243d/keyboard-not-recognized-driver-update-error-with?forum=windows-all)

  2. In Device Manager: View → Show hidden devices. Uninstall all keyboard/HID keyboard entries, uninstall USB Host controllers (if applicable), then reboot and let Windows redetect. If Device Manager still shows “This device cannot start (Code 10)”, follow Microsoft’s Code‑10 troubleshooting (update drivers / uninstall & let Windows reinstall the controllers).
    (Microsoft: Error codes in Device Manager — Code 10 guidance.)
    (See: https://support.microsoft.com/en-us/topic/error-codes-in-device-manager-in-windows-524e9e89-4dee-8883-0afa-6bca0456324e)

  3. BIOS and hardware checks: update the GA‑K8NF‑9 chipset/USB drivers and BIOS from Gigabyte’s downloads page, reset/clear CMOS per the manual, and double‑check the board’s USB/legacy USB settings (these control how USB devices are presented before Windows loads). If you’re using a PS/2 keyboard, plug it in before power‑on — PS/2 ports are not designed to be hot‑swapped. (PS/2 hot‑plug info: https://en.wikipedia.org/wiki/PS/2_port)
    (Gigabyte downloads/manual: https://www.gigabyte.com/Motherboard/GA-K8NF-9-rev-1x/support)

Practical note: several members here (notably and ) pointed at BIOS/USB emulation as relevant; buying a working USB keyboard (what ended up doing) is a valid, simple workaround while you apply the OS/registry fixes above.

Sounds like either a bad keyboard or a bad keyboard controller.

Try using a different keyboard, if that doesn't work you're looking at a new motherboard (though sometimes a USB keyboard works when a PS/2 keyboard doesn't, but that's rare).

I've already tried a new keyboard & the motherboard is brand new already, I only bought it on Sunday with the other items in the machine.

Thanks anyway.

Hey buddy. I found the solution to your problem if you still have it. :D

The fix is to disable USB Mouse Support in BIOS. That will free up the resources the keyboard needs to load properly in Windows. It also does not affect a USB mouse if you are wondering.

I have the same motherboard and searched high and low for a fix becuase I didn't want to return my motherboard (yet again). I've been through 3 power supplys and two motherboards until I finally got a system working properly. I'm now a happy camper!! :)

Hope this works for you.

G'day Ken,

Mate, sounds pretty promising, I do have USB mouse enabled in the BIOS (cause I have a USB mouse). Unfortunately I have solved the problem by purchasing a USB Microsoft keyboard....least it works.

Doesn't really matter because Dad has my old system with my old keyboard which works fine with it.

Really appreciate your response & I'll definately throw that in the memory banks for later use if needed. :cheesy:

Thanks again
Greg.

Just an FYI: You can use a USB mouse without USB Mouse support enabled in the BIOS. I think it's a DOS thing, emulating PS/2 functionality when the BIOS recognizes there's a USB mouse.
