Sony Vaio keyboard issue

[Hodsocks]

I am having a strange issue with a Sony netbook (VPCM12M1E) in that the keyboard seems to have a mind of its own, it used to be an intermittent issue but is more prevalent now. The issue is that if I try to type it enters the letters in capitals, if I press CapsLock it goes back to lower case letters. If I use the numbers, ie. 1234567890 they come out as !"£$%^&*(), whatever I do with CapsLock or NumLock. If I try \,./ I get |<>? However if I boot into safe mode it all seems to work fine.
So far I have restored back to factory, reloaded the drivers for the keyboard and pulled my hair out and there isn't too much left now. Have any of you guys any words of wisdom for me

The replacement keyboards are not expensive. Try a new keyboard. Other than this, the motherboard may be the cause
