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.

Could you add information about your graphic card and its driver. Another point, you may play with preferences > video > output. you need to restart VLC to apply, Some modes may work better – Sneetsher Feb 13 '14 at 21:36
ATI Radeon HD 7560D video card. Not sure how to find the driver. If it were a video card issue why would it stop working all of a sudden? – Jason Smith Feb 13 '14 at 21:43
ok changing the preferences>video>output worked for me. – Jason Smith Feb 14 '14 at 15:15
Nice to hear that, could you write an answer. – Sneetsher Feb 14 '14 at 15:32

I found a resolution to my issue by going to:

Preferences → Video → Output: Changing from Default to OpenGL
