Computer trouble

So you are saying this is a software issue, not a hardware one?

I don't see how that is possible.

Absolutely. and everyone except MS support agrees that it's impossible.?ÿ

What your computer is hearing when you touch the 9 key, It is not understanding the command and doing nothing.

At least your top number line works.

I'm going to go out on a limb and assume that the keyboards are wireless.?ÿ That being said, when you switch keyboards are you switching the wireless dongle on the computer??ÿ I have found that on my system, if the dongle is on the back of my tower my keyboard acts really goofy.?ÿ If I put it on the front of the CPU then it works fine.?ÿ I surmise it is a signal thing.?ÿ

On a side note, before I switched to an AMD processor this winter I kept the dongle on my monitor.?ÿ The new motherboard will not run the BOIS if the USB is plugged into my monitor.

This seems to be something that HP should fix... are you under warranty?

I don't know a thing about Carbonite ... if it will truly preserve your data and settings... I suggest you duplicate your "backup" in some manner to preserve your Personal Data.

Reinstall of Windows "should be" trivial, hopefully you can create some sort of reinstall DVD or USB to do a fresh install with all the drivers required

anyway, you could confirm the "software fault" theory by booting with Live Linux system to check. no need to install anything or touch your disk drive.
My money is on "this is a Windows bug"

USB Keyboards. Tried different USB ports.?ÿ

Could be a BIOS problem rather than Windows. I which case the fix would be a BIOS update. Scary, but not super complicated. Check Youtube for?ÿ instructions.

Totally believable that an operating system re-install would fix this. I just recently got over some erratic behavior with a Lenovo laptop that was cured by an automatic Windows update. Seems that a previous update had been interrupted, leaving the thing hamstrung in odd ways.

Peter, yes it's on HP warranty but HP support is closed for the virus. I did get DVD's with OS and Driver Recovery from HP.?ÿ

I would make a Windows refresh the last ditch effort overall.

The first thing I would suggest is check with the HP support site to make sure you've installed all of the latest drivers, particularly for input devices. But I would just make sure they were all updated across the board. https://support.hp.com/us-en/drivers/desktops

If that didn't fix it, then you could run some DISM commands from the command line to make sure your Windows installation doesn't have any corrupted files. To do that, click Start, then type CMD; choose Command Line and be sure to run as admin. Then run the following commands in the order provided:

• dism.exe /online /cleanup-image /scanhealth

• dism.exe /online /cleanup-image /startcomponentcleanup

• dism.exe /online /cleanup-image /analyzecomponentstore

• dism.exe /online /cleanup-image /restorehealth

• sfc /scannow

Some of them will take a little while to complete.

If that still doesn't fix it, then maybe consider a soft refresh, where no data is removed but Windows is basically reinstalled. You'll have to reinstall your software though, so make sure you have your keys, etc. handy.

And if that doesn't fix it, you might consider a clean install. The latest update of Windows 10 has a pretty nice setup for that now that will automagically download the latest W10 version from the cloud when it starts the reinstallation process. I just did this for a client and it was super easy.

Thanks, Wendell,

I reinstalled the input drivers. The rest is too scary for me. I may take the keyboard apart and remove the offending key.?ÿ
