I was just normally surfing and playing some music then all of a sudden I get bad lag, the system just hanged up, and nothing could be done except the option to log out. I logged out then clicked on the option to shut down. It took a good 5 mins to shut down. Then upon rebooting. The login screen showed up just fine. I typed in my account and now my background picture is gone, all the desktop icons seemed to have got up and left. And when i try to play a music file it doesn't know what program to go to and then it still doesn't play. It shouldnt be a virus because I only had the system up and running for about 2 days now and it was doing alright until just now. Lucky me firefox still works!
