I have been listening to CD's for the past couple hours on my computer, I just switched CD's and i get this...

I was having problems with low virtual memory awhile ago but have not had any warning notices pop up in the taskbar since i disabled some of my useless start up programs.
I have no idea how director5 player is on my system and if i even need it, I just listen to all my music through windows media player.
I don't know much about computers, But i love when you get messages like this and all it gives you is an OK button...Like, Don't give me any ideas on how to fix the problem or anything
So anybody got any advice on this?
Thanks very much.
