I have looked in /var/log/messages, couldn't find anything there,
anyways, it didn't crash today, maybe because I was home all day and was
using it all the time (or the kernel headers update?). It'll probably be
crashed by tomorrow morning, and i'll messages again.

thanks for that, I can't really check this right now, as we are watching
a movie on mythtv (nice) and i dont want to crash it! so I'll check this
later, but I highly doubt that it will work, as not even the num lock or
caps lock buttons work.

It could be a power problem as Michael suggested, I havent disabled
anything in the bios, will try that on next crash. One thing worth
mentioning is that I do notice weird behaviour with my external hard
drive, if i restart the computer, it is mounted normally (/home in fstab
using uuid, XFS), but if i shutdown let the drives power off, and then
power on again, it fails to mount. and i have to manually change tty and
mount it, but since I wasn't planning on powering the machine off often,
this didn't bother me, but maybe it's realted to the hanging? could it
be that ubuntu puts hard drivers to sleep and doesn't get them back on?
maybe, anyways, i'll keep you up to date as soon as i get anything.
thanx for the help.
