    Ubuntu keeps crashing (again after fresh install)

    Hi all,

    My ubuntu box keeps crashing for (to me) unknown reasons. This happend with 12.04 and the problem remains after a fresh 12.10 install. It is very unclear what happens. As soon as the machine start random applications fail and I'm shown a window stating Ubuntu had an error and the application must be closed. It is a different application every time. Then at some moment, sometimes within a minute, sometimes after two days the machine just stops. Sometimes I just get a black screen, other times I get screens as in the photos I attached (different every time) and at other times there is no output to my screen at all anymore.

    I have no idea what information would be needed to tackle this problem but the output of lshw can be found here: LIST OF HARDWARE .

    Normally I would take a look in the logs but another unfortunate part of this problem is that >14GB of system log is created, which is, a lot.

    I have done a memcheck and diskcheck. No errors were found.

    Any hint on how to fix this problem is very welcome.

    Please give a complete hardware description.

    Have you tried the memory test in a live boot?

    There is a link in the topic start to the complete hardware list, I made the link more prominent. I also updated the post with the fact that I did disk en memory checks and that no error were found during.

    It seems you have both Nvidia and Radeon graphics cards. Have you tried removing one of them?

    Actually there is only one graphics card (ati). There are no onboard graphics either.

    Does this happen in a Live CD session with Ubuntu?

    Try a live session with another distro. Does it happen then?

    Are you sure your install media is clean?

    As large as they are, your logs are probably a very valuable resource for troubleshooting this.

    I have not seen this problem in a live session. However, as I mentioned this problem does not occur after a fixes time period. Sometimes it runs for two days without crashes

    My guess would be a hardware failure. Could be the commonly overlooked power supply or simply some connections have come loose.

    Yes that was my guess as well. All connections seem fine. I have replaced the power supply to no avail.
