Been having a problem for the last 2 days where my computer decides to start randomly pressing keys by itself, meaning the computer mutes and unmutes itself at random times in quick succession, keys become unresponsive whilst others press themselves. At times I've come back to the computer to see 10 folder windows have opened by themselves with searches like 'jkjkjkjkjk' or 'aaaaaaaaaaaaa' open in them. Is this a fault with my mobos keyboard controller?
