Re: System reboots between 5 and 10 minutes of viewing video file
Even if it's 5 minutes old, if there's a defective solder joint or a weak component on it, then a full power draw from the CPU + GPU might be enough to cause it to reset. The only way to confirm that the PSU is the source of your reboot would be to substitute a different known-working PSU.

As posted above, the problem is either the CPU heatsink is not doing its job for some reason, or the PSU has a weakness that is triggered by heavy workload.
Could X be implicated? Or screensavers or power-management?
