Ubuntu freezes randomly

[hugolp]

I installed Ubuntu Jaunty formating a Intrepid installation. With intrepid the computer was working fine, but with Jaunty it randomly freezes. I believe is a X problem because when working with the console only it does not happen. Sometimes the computer will not freezes but all the programs will get closed.

I am using the Jaunty i386 (installed from the alternate cd) on a AMD 4200 dual core with 2 Gb RAM and a Nvidia 7100GS.

So far this is what I tried:

1) Installing Jaunty, then trying to update the packages. It never ends, it crashes duing the update.

2) Installing Juanty and installing the nvidia propietary drivers with the gui first, restart and then update the packages, but it crashes again.

3) Then I installed again but this time I use a console and tried to update from there. It crashed again.

4) On the console I killed 'gdm' so X is closed, and then I update. It updates fine (that is why I am guessing its an X problem). But once I go into the system it keeps on freezing randomly.

5) I have downloaded the Nvidia newest stable driver. I installed Jaunty again, from a console killed 'gdm', installed nvidia driver, reboot, in a console again updated the packages, reboot. It freezed again.

I attach my Xorg.0.log

This is getting very anoying and its imposible to use the computer for anything since it could crash at any moment.

I did not find a way to add the report to this bug so I opened a new one: https://bugs.launchpad.net/ubuntu/+source/yelp/+bug/379400

Thank you for submitting the reports!
I've marked this one as confirmed and the other one is attached as a duplicate.
If there is more information needed you will be asked again.

If it is of any use, with compiz off it seems to be behaving better. It stills hangs sometimes, but a lot less frequently.

This bug can be closed. The problems where happening because of a faulty RAM module.

Thanks for letting us know.

This is a Lenovo T61p w/4GB RAM.

Yesterday, the following was logged after I was trying to maximise a window in Firefox (Compiz was running). The system froze, but not hard -- drive light etc was flashing after the GUI froze:
