This question already has an answer here:

I currently use Ubuntu 13.04 on LG X110 notebook After last updating (on 28th August 2013) software doesn't work. It suddenly stops while I'm using it. Hardware still runs: I know because of the noise, but noise it has during doing no operation. Software doesn't work at all: desktop is frozen, mouse is blocked, any keyboard command gives no result. I already uninstalled Xubuntu, in case there was some bug with it, but it just doesn't matter.

Any suggestion?

This question was marked as an exact duplicate of an existing question.

If it is happening to you after installing a different operating system it is probably a hardware problem.

Sounds like you could have a problem with your ram. When you turn on your computer and grub loads, run memtest+ and let it run overnight. If it gives any errors then your ram is the issue and you should replace it.

Thanks. (I use Ubuntu on this notebook since July 2010, however). I installed grub-customizer to have memtest86, because I don't have it at all. but now it doesn't allow me to run grub-customizer. do you know which command may I insert to run the programme via terminal ? – AlexanderFreud Aug 29 '13 at 20:45
So memtest runs without the operating system, so that's why it has to start at the grub loader stage. Another option is to download the program, burn it to a cd, then boot from CD. I've had to do that before – Anake Aug 30 '13 at 11:03
Thanks for answering. I noticed another point: laptop works quite good with at most 70% RAM; suddenly a new process, named zeitgeist-fts, appears and it uses 390-430 MB of RAM and computer stops! Do you know if is it this zeitgeist usefull for something ? (I don't think so because it starts to run after several minutes, not at turning-on) and How could I delete it ? – AlexanderFreud Aug 31 '13 at 9:28
Ok, so you have probably run out of RAM and that's why its frozen. You don't really need zeitgeist so removing it should sort you out. See here:… – Anake Aug 31 '13 at 18:26
I removed zeitgeist (almost all packages) but I remained with no desktop and with no Gedit programme (a part of the -useless- left side bar - I already have Docky). So I installed again zeitgeist packages; but I am still without desktop! Please, what can I do ? – AlexanderFreud Sep 1 '13 at 15:07
