Leon can you try and start it in "Safe Mode"? I am assuming it is Windows 8! I must admit the smiley face gives me cause for concern, these sort of things appear if you have some serious issues with your computer. Yeah I know it wont boot and that is serious, but I suspect you may have some serious malware infecting your system. Others here are much more versed in computers, and can steer you better.
