I've been having trouble with my stupid **** computer for the past couple of weeks, it's giving me a bundle of error messages and running extremely choppy and slow. It started about the time when I started having trouble with Windows Live messenger. Whenever I log onto my account I get a message saying "Windows Live have repaired a critical component, you must restart messenger". And now whenever I type cmd into Run I get the following: what's going on? & sorry if this isn't the place to post, I'm obviously computer retarded.
