toshiba keyboard inputs faulty

[someroginalusername]

hello,
my/our problem is as follows:
when inputing i, io will appear.
k results in kl
, in ,.
8 in 89

the problem first appeared about six months ago, but went away by pressing the [num] key.

since my knowledge regarding computers is limited, I fear deinstalling drivers, removing keys and the like.
is anyone familiar("famiolioar") w this problem?
do you have any advice?
thanks in advance

You either have spilled something and you have stuck keys, bad connection to the motherboard or a bad keyboard. Replacement keyboards are pretty cheap on ebay, try a new keyboard.
