So im at a loss on what to do here

[Ace-o-fire]

So, every now and again, my sound was randomly muting, and the windows search was opening it's self. at first i thought that was the problem, but the more i am exposed to it i feel it is my keyboard. I can be typing or moving around in game and keys will start sticking. or or the sound will mute or the windows search will open. i have noticed one particular set of letters appear when im typing. "asdf". it looks to be copy/pasting those letters extremely fast. i ran my antivirus and spyware multiple times and came up short. ANY help would be much appreciated.

its gotten to the point no where my computer is unusable since i no longer click on icons to lunch items and the system slows to a halt when going through the start menu.

Use a different keyboard. See what happens.
