Hi it seems that updating BIOS has not solved this issue as my Desktop just 
crashed with the new BIOS.
See the requested output here.
$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
L01 v02.65
07/13/2015

What happens is that my desktop completely freezes and the only thing that is 
responding is the mouse pointer.
I'm able to move the mouse pointer, but there is no reaction to any keystroke 
or mouse click in the DE.
Gnome system monitor also stops updating.

Sometimes I'm able to Ctrl + Alt + F1 to the terminal and type my
username and password, but I never get a prompt.

I use sysrq commands to reboot the computer.

After the reboot checking the atop snapshots created around the time the OS 
gets unresponsive shows that kswapd0 is generating high read load on the root 
volume (system_vg-root_lv) and hereby also on the disk containing it (sda) and 
also high system load (PRC | sys   18.59s  | user   0.20s  | ).
The disk and the volume are both 101% busy and there is a heavy read on them: 
MBr/s 362.31 (it is and SSD).
There is also another disk in the computer and there is no load on that.

Memory usage looks like this:
MEM | tot     7.7G  | free  127.4M  | cache   1.3G |  dirty   0.0M |  buff    
0.4M | slab  118.6M

So it looks like kswapd0 is heavily reading the root filesystem or
partition which is generating a high system load and killing the OS.

If you need any additional information just let me know.
