Hi,

Ran across a weird problem within the last week. My computer will inexplicably start writing z's. At first I thought the obvious- stuck keyboard. Unplugged that (USB), still writing z's. (Confirmed by opening Text Pad and watching the z's scroll.) Then disconnected all USB cords (mouse, joystick, external HD, etc)- still writing z's. This is usually remedied with a reboot, then all appears well.

I've ran AV scans and MBAM scans- no discrepancies.

This issue mystifies me. I may go two hours or two days. I cannot intentionally duplicate it- it just starts on it's own. (Or, more accurately, I notice it when I use a writing/email app or a program that uses the Z key for input, and see/hear the results of a stuck Z.)

Again- this happens even with the keyboard disconnected. I welcome your help and appreciate any info you may be able to provide me. System info below my signature.

Thank you,

czar

It's sleeping... :huh:





Just kidding. :huh:

Seriously, though...that is strange. What happens when you boot into Safe Mode?

Now *that's* funny!

On a reboot- it's fine. I had zero input devices connected, and it was still writing z's (prior to the reboot). I'm starting to think outside the box, and will manually update java, adobe air, flash, etc. I've been a techno freak for awhile and I've never seen something like this.

Thanks again for the chuckle.

I would try deleting your keyboards via Safe Mode from Device Manager then reboot your computer.

Would you do this even though, after disconnecting the keyboard from the USB port, the z's still write? (Which, presently, leads me to think it may not be the keyboard?) I'll try it, but want to be sure you realize that, once started, it writes z's with nothing (input device-wise) connected.

Thanks for the reply,

Yes I would, as it could be a bad driver.
