[ubuntu-uk] Ubuntu Crashing

[Seif Attar]

Hello,

I have ubuntu 7.10 gutsyx64, installed on a new machine I bought, after
finally getting everything on there, I noticed that it keeps crashing! i
dont know what causes the crash, it doesn't happen when I am using it,
usually happens when I have left it for a while (no suspend used, only
blank screen on idle), when I try to resume my session, the screen works
normally i can move the mouse, see the applications that were already
running, but i cannot start new apps, cannot ssh into the machine,
cannot access apache! now you can imagine how annoying this can be,
especially when it crashed when i am away from home and need to access
it!

Can any1 give me advise on how to troubleshoot this?? I can't run dmesg
and don't know what logs i should be checking since a hard shutdown is
forced!

I did try disabling the nvidia-new driver, thinking it could be causing
the failure, but it still occured!

Thanks in Advance,
Seif A.
