Last night I was just getting off the internet and listening to some music in iTunes when my Powerbook G4 decided to go to an all black screen with some text in the top Left-Hand corner of the screen. This is what it says: Darwin/BSD (XXXXXXXX-XXXXXX-Computer.local) (console) login: Just for security purposes I put X's where my name appears and it's asking for a login. I have tried typing my name and then attempting to put a password in, but it won't let me type anything in for the password. All I can do is hit enter and it says Login Incorrect and flashes a quick line of code or something and goes to the blue screen that you see right after your Mac loads up. I honestly don't know what's going on. The only symptoms that I can describe that was happening right before this occurred was that the internet on Safari started chugging a little bit speed-wise. When I went into iTunes and was using the scroll bar to go through my music it was going a little slow too. After that I remember hitting the power on/off button to shutdown and moments later, instead of giving me the option to put the computer to sleep-restart-shut down it just did what I mentioned above. I don't know if this is a virus, if my computer has been hacked or if I'm overplaying this in my mind, but I need the use of my comp this weekend to do work for a research paper and other assignments that have to be completed before class next week. I know this sounds confusing, if someone needs me to post a picture of this to make any sense then i will try to. If anyone can assist me on this, it would be much appreciated.
