Hi Fabio. I did run one complete memtest and the result was "no errors". I did that yesterday morning.
I kept on trying to work but the pc frozen more and more frequently. Thus, this morning I have decided to install ubuntu 11.10 (I had 11.04 before the upgrade to 12.04), I have restored my back-up and I am "on the road" again. Once 12.04 will be more stable or the problems will be solved, I will upgrade. Thank you very much for your kindness and patience with me Luisa. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/999270 Title: Ubuntu 12.04 LT frequently freezes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/999270/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
