Computers rebooting unexpectedly

[PaulHA2]

I have two computers, both Dells, one less than a year old, one 4 years old. Both running 10.10, the new one with libreOffice, the old one with OpenOffice. Today, they both started rebooting unexpectedly and returning me to the login screen. I did a complete reinstall of 10.10 on the older machine, and after an hour or so, same problem again. The problem only happens (so far) when I'm running the office software, and there are no temperature issues with either machine. It's incredibly frustrating, and weird--two different machines same problem out of the blue, even after a clean reinstall?

The only new software I've installed recently is Banshee and gpodder.

A buggy recent update?

Any ideas?

What are the last entries in /var/log/syslog before your system reboots?

[PaulHA2]

Thanks for the reply. Can you tell me how to get that data?

[Cyclane]

less /var/log/syslog
match the times with the moment your system rebooted and copy/paste that between code tags in the forum.

Okay, got it. Don't know how much you need:
