I have just got my laptop back, new motherboard, new OS install, all good.

But somewhere in my usual reinstall process, the inputting of keyboard characters has become messed up....

Heres some things its doing:

Key:

Z = turning on the caps lock
M = types an m, but the cursor moves behind the m, so out of order messed up words occur
X = x\
T = nothing, pc just sounds a error beep
? = :?
/ = ;/
Delete = hold it down = deletes nothing and just moves along the characters unto stop pressing delete key
Delete = 1 press = deletes intended character, and then the cursor moves in front of the next character, so out of order

Its also changing????
T = works now
M = nothing, pc sounds error beep, then cursor moves back 1 to previous character


What the hell is happening?

I figure it to be a text input of some kind...maybe I've accidentally turned something on....

Anyone please help and tell me where to find this and turn it off, put back to norm?
