glitch

I'm having some problems with my keyboard, if I press the Ctrl key it glitches for some time.

For example, if I press Ctrl and press Tab while it's still glitched the computer shuts down as if i pressed the Power On/Off button. If I press a it "presses" Alt, A and a symbol I can't remember, if I recall correctly it's a currency symbol. If I press Ctrl again it "presses" the ' key.

I'm using Windows 8 Single Language 64 bits with a ABNT2 keyboard. The processor is a Intel Celeron G530 with 2 GB of RAM.
