Greetings again.

I installed this fresh Ubuntu 12.10 amd64 two days ago. I got great experiences with Ubuntu some years ago, and I opted to get back.

From the first boot I proceeded to install most of my common packages, and the system randomly crashes. Only the mouse responds to my movements once every 5 or 10 seconds, and at the same time the (default) sound system goes one step further on its buffer. Everything else gets locked up, including the keyboard (even SysRq keystrokes), leaving me with the only option of a hard reboot.
This can occur 15 minutes since its boot, or sometimes when changing tab on Firefox, or playing on Steam. This gave me worse problems when installing nVidia drivers and/or frglx (on Steam demand), losing panels on Unity.

I gave a couple of looks to syslog. The only last entries before reboot are about AptDaemon.PackageKit starting and quitting every 5 minutes. I don't think this one is the killer, but I'll leave it here for extra information: http://pastebin.com/y0dAv34F

I think my nvidia-current drivers are not active right now, and I read they currently give a lot of problems with Compiz (I was using Mint Debian for a month, and the window manager was almost invisible until I set Compiz off).

It can't be CPU temperature problems, since this doesn't happen with any other OS, and I always keep an eye on cpufreq.

Crashes happen also in GNOME, even no-effects.

Somewhere else to look? Or should I immediately try with another flavor or distro?
Thank you beforehand.
