I found myself unable to log on because typing my windows password was impossible ( managed to do it with on screen keyboard )

the problem is that when i press " i " for example it types "]i", when i press u for example it types " hyu " and very strange when i press backspace it prints the time and date ( no idea how this happens ).

Problem goes away after like 2-3 minutes after i successfully logged on and everything comes back to normal.

Shutting down/restart of computer does not fix problem and the problem continues until i log on in windows even if i leave the computer for 10 minutes and come back.
