Pacman dying??

[eccs19]

Is my Pacman dying on me?  I've just got it together, and been using it for about a month.  I went to play it last night, and after playing for a couple of minutes, it re-booted on me.  I turned it off, and on again, and same thing.  Sometimes it would not totally boot up, but just keep re-booting.  I had to leave, so I left it alone.  Once I got home a few hours later, I fired it up again, and it ran fine.  Anything I should be looking at next time I've got it opened up?

Check the power supply's voltage.  A power supply is easy to replace and can damage your board if faulty.  So it's worth it to buy a new one, regardless.
