Not necessarily. A while back, I had a computer that rebooted at random intervals. When it rebooted, it was like a hardware reset, no error message, no shutdown; the thing would just blink and boot up. In the log files, I could find the point where it booted up. In the minutes leading up to the reboots, there was no unusual activity or error messages.
I determined, by swapping parts with a similar computer, that it was not due to the memory or the power supply. I figure it wasn't due to overheating because it sometimes would reboot within a minute of a cold start. My best guess: something gone wrong on the motherboard. I gave up. That computer is now spare parts.
Edit: Forgot to mention, it failed the same way in Linux or Windows, so I knew the problem couldn't be software.
