HELP! Something keeps sending keystrokes through my system!!

Hi!

Here's a problem I've been trying to find advice on the internet about, but nothing I've tried so far has worked. Maybe somebody here will recognize it?

I have an HP DV7-1030eg laptop and am running Vista Home 64 bit, and lately, there has been some invisible force that seems to be sending keystrokes through my system and messing up my volume settings. Here's some things that happen:

- when I use ALT-TAB, the bar (the ALT-TAB window that pops up in the middle of the screen) will just disappear
- IrfanView will suddenly jump to the next picture or quit full screen mode
- screensaver doesn't stay on longer than a couple seconds
- sometimes, my sound volume will drop, shake up and down a bit and then go all the way out. When I open the volume settings, I can see the volume slider wobbling around at the bottom

Needless to say, I checked for viruses and stuff, then I looked for advice online: the ALT-TAB problem seems to be pretty common, esp. with DELL notebooks (?), and people have had the same issue with IrfanView. I hear that removing the notebook's battery will help because there is electric tension building and that triggers unwanted impulses. And it's true, when I remove the battery, the PC becomes more stable - for a short while. Then, the problems reappear.

I checked out the test field in the FilterKeys feature, which emits a clicking sound at every keystroke, and it's clicking like crazy. There's roughly one keystroke a second happening in my system right now!!

Maybe my setup is not properly grounded? I live in an old house with old wires etc. - how do I discharge electrical tension from an object? Or do I have too much stuff connected to my computer that creates an electric field? I have a 2.1 stereo system with ground loop isolator, an external monitor and USB mouse/keyboard.

Any ideas?

Thanks guys!

 

Have you tried to disconnect the connection?

 

try using your laptop somewhere else, front yard, inside a car, etc.

 

Yeah, yesterday I let it run on battery until it was completely drained, then used it with connection a bit more - problem gone. Overnight I had it off and disconnected, and this morning when I turned it back on - again without cable connection - the problem was back. So the tension seems to be building within the laptop itself, even when it's not connected to power.

 

Faulty keyboard?

 

Yes this is a case of a faulty keyboard. You can call up HP, your keyboard will be replaced only if any 2 or more keys in your keypad are non-functional, that too only alphabet keys and number keys. You won't get a replacement for special character keys that have gone bad.
