Thanks - yeah I have 'system mechanic' on my machine but that didn't solve the problem - but the program is really good. I have managed to fix the problem its seem that there was two keys in the registry that shouldn't have been there. I did a search on goggle (for code 19) and low and behold there have been a few with the same problem. I would have never found the dodgy keys myself - thanks for the input.
