it all started when someone gave me a virus on msn since then my computer has seemed to gone from bad to worse. Its got to the point when i turn on my computer it loads up but when it comes to the bright blue log on screen, instead it goes blank and freezes, sometimes it even says no input signal. Then i have no choice but to turn my computer off by the mains and then start it back up where i get the option to go on safe mode and then it works. However this isnt right there must be something wrong with my normal mode. Has anyone got any ideas how to fix this problem ? i cannot get onto the normal mode at all!
