X configuration file

Video playback has started causing random reboots.

To rule out hardware failures (memory, CPU, GPU), I ran four different stress
test (listed below), all of which completed without errors.

Reboots occurred from few minutes to up to 30 to 40 minutes from the start of
the video. They have occurred both with mplayer and Adobe Flash Player plugin.

Usually there has been no log files. However, in one occurrence mplayer simply
crashed and the machine didn't reboot. I'll attach those logs in case they are
relevant.
