Hi John,

Have you checked the PSU so there's no dust clogging the vent holes? The
same problem happened to me with a Decstation where the vents were so
clogged that it looked like there was a filter on there, it wasn't it was
a solid mat of dust! It caused the PSU to overheat and shut down and
still the box was in and air conditioned room.

If this isn't the case I would suggest that you follow the other advice
and check the output of the PSU with a multimeter.

the one thing that keeps men ahead of them.
