kde causes reboot?

My machine (which had 2 cases of RAM problems and exchanged) rebooted again today. I did not see the screen clearly when I pushed return and then it started the rebooting process. here is what is in /var/log/messages:
Code:

that could be causing the core dump? kdeinit4- what is that?
 
Have you tried booting in safe mode or do a single user with fsck after the reboot?
 
kdeinit4 are background processes that KDE4 spawns to launch and manage it's applications. Or something like that :)

It's very unlikely that the kdeinit4 crashes are causing your entire system to reboot. More likely, something else happened to your system that caused KDE4 to crash and also caused your machine to reboot. My guess would be either hardware issues or video card driver problems.
