Im having a wierd problem on my laptop. It is not constant, and seems quite random.

I will be typing and it will begin to spam one of three keys, [TAB] T or { , and it wont stop until I turn it off. It has been a problem for a while. I have removed and cleaned the keyboard on the laptop, and cleaned the usb keyboard, no keys are stuck.

I checked for Adware, Spyware and Viruses, but came up with nothing.

Can anyone help me out with this?

Are you sure its not a keybord fault.

It may sound like a software problem. Otherwise it's in the keyboard itself.
