Windows 7: Any USB Keyboard repeatedly pressing the 'f' key

04 Jan 2012   #1

Windows 7 Ultimate x64
Any USB Keyboard repeatedly pressing the 'f' key

Yesterday at work, using a keyboard I have been using for a long time now (Typematrix 2030 usb keyboard), while I was researching work subjects on google, my computer had a visual hiccup (as in the screen freezing for about a half-second, then continuing like normal) and within a few seconds acted as if I were holding down the 'f' key. Unplugging the keyboard did not stop this behavior. Holding shift/pressing CapsLock changed the casing from 'f' to 'F'. Likewise any other normal keyboard entry by me was interpreted with no issues. In addition, with wordpad open, and the 'f' characters being printed, actually holding down the 'f' key made them print twice as fast, showing my key was not stuck down. Again unplugging the keyboard changed nothing as well as plugging in another known good keyboard (a co-workers keyboard). Another thing is when I press the windows key down, 'f' characters are entered into the search bar. And when hovering over certain things like the 'show all programs' link, changed the 'f' to a '5' and about half the time, stayed a 5 rather than an f.

So I rebooted into safemode with this keyboard plugged in, and after about 30 seconds the system continues as if the key was being held down. So I rebooted the computer with an alternate keyboard and all seemed well for about 5 minutes. I opened up notepad to see if it would happen and after about 5 minutes it started to press the f key again. The same happening in safe mode with the new keyboard.

the first thing I tried was removing the drivers for all keyboard devices, which did not work (did that in safe mode). So I looked around the office and found a wireless keyboard that syncs with the same receiver as my mouse, and activated that. The problem stopped happening. The next day I brought my personal keyboard from home (the wireless kb I did not like) which is also a USB keyboard worked fine. But I did notice that when plugging in this keyboard it had to install another driver. So I'm thinking that the default keyboard drivers may be corrupt as any keyboard I use that has a different, or specific driver, does not have this issue. As soon as I plug in either of those two keyboards, the problem occurs again as if I were holding down the 'f' key.

So I'm asking, how can I fix this? I do not care for the other keyboards and would like to use my typematix keyboard. They do not offer a specific driver as it uses the default usb keyboard driver. Uninstalling and re-installing the drivers did not help. And using this keyboard at home, in the same OS (Win 7 x64) this error does not occur.

Any help is greatly appreciated. Thanks.
