All of a sudden, when I launch VLC and try to play a video it freezes my whole system including the mouse. The only options I have is to press the power button or use the REISUB series of commands. I noticed that there is sound. I've been checking around the boards and a lot of the posts with issues similar to mine seem to be several years old.
My computer has 10GB of RAM. I have Lubuntu 13.10 dual installed and when I switch over to Lubuntu videos play just fine.
I have already tried checking the Task Manager to find out if there are any processes that are using a lot of memory. Firefox was only taking up about 400MB of RAM and the computer still freezes. Even the Task Manager froze.
