WampServer

Hi,

I have been using wamp for about a year trouble free. However, yesterday when I went to use it, it stopped working and my mysql root password has been changed I can't log in. Also lately my computer has shut down by itself a few tims and I have been prevented with a blue error screen. I'm a little baffled why wamp is not working, could I have been hacked???

And if so how is this possible???

Thanks in advance for any help.
