Exit the MATRIX

Guys, maybe you are right. I was focused on the SDD and didn't think it could be a memory problem.

In this moment I have 5 tabs open, Skype, VLC and a PDF reader. The memory in use, according to top:

KiB Mem: 3833472 total, 3651680 used, 181792 free

But according to top, the sum of the % memory of active processes is ~41%
