Computer receives an input it shouldn't receive (up-arrow)

Marksel · Dec 22, 2014

So my computer is constantly receiving the up-arrow input, and I can't for the life of me figure out why.

This happends regardless of which keyboard I have plugged in (tried 2), and even happends when there isn't a keyboard plugged in.
The keyboard I use do not have this issue when plugged into my laptop, so keyboards are not the issue.

Some extra information:
Current keyboard: Coolermaster TK Stealth
OS: Windows 7 64-bit
motherboard: a Gigabyte with model: Z87-HD3

I am completely clueless where the problem may be, I'd love to hear your suggestions!

EDIT: forgot to mention, I already tried to delete any old keyboard drivers as well as uninstalled the current keyboard device drivers.

Does your keyboard require an application to designate your key bindings or macro?

plaintuts :

It does not

Can you check on
Control panel>keyboard settings
If anything is a miss or changed

I don't really know what I'm looking for here, it seems normal but this is the first time I've looked at these settings.

Do you see a tab for hardware

Marksel · Dec 22, 2014

yes, it says this device is working propperly

Are you willing to download a third party application to disable certain keys in the keyboard?

Its called keymapper (yeah, the name alone is suspicious) it can disable selected keyboard inputs.

Just to test if the I/O controller is indeed sending key inputs on its own

Installed it, disabled up arrow, rebooted and it is still receiving the up arrow input.

Then that is bad.

Something has messed up with the system registry. Kinda hard to remove because it requires configuring global settings.

Oh, be sure to remove that keymapper (dont trust things that can monitor your keyboard inputs)

Try updating windows and your motherboard drivers

I will have a further look at this tomorow when I have more time, for now thanks for the help and I'll report back once I have my results!

Update: it turns out it was a device called VJoy Virtual Joystick under the HID devices that was causing this, disabled it and everything works propperly now, thanks for the help!
