If you are sure it is not heat related, then I would look at a PSU or MB
issue. Those are tough to troubleshoot without good spares around (or a
multimeter for the PSU). There is one thing I had problems with that caused
intermitten shutdowns and that was a bad SATA power connector on my system
drive. It was cracked and occaisionally would lose contact and the entire
system would shut off. I found it by actually tapping on HDDs and other
components with a small plastic hammer while the system was on (not
banging.... until I finally found the culprit. It is a long shot, but you
could check the power connector on your HDD. I have never heard of a Hiper
PSU so I don't have any idea what kind of quality they are. I always use PC
Power and Cooling PSUs because I just never have had a problem with them.

Well the problem went away after I posted this message on the 7th Dec.
Today is the 12th Dec, and I had an instantious shut down twice in the
past 30 mins. Both were while watching a DVD at full screen, from the
DVD drive. My hard disks are fans were active too.

My 250GB "shares" a molex connector with my DVD-/+RW drive. In other
words a molex lead from the PSU goes into the DVD drive, and then
another molex comes out of that one, which I have put into the HDD. Is
that ok?

Is there any way I can monitor my PSU through windows?

There used to be a great program that showed voltages, temps,
everything, but that's not important now, since it no longer exists for
newer MBs.

Yes, you may be drawing too much current from that particular output
from the PSU. Leave one drive attached and attach the other one to
another power lead that is (preferably) without anything else on it, or
at least has a low wattage device only. Can't hurt and it may be the
problem.

I just went through replacing a MB on my computer which displayed the
same sytoms. Turned out it was "bulging capacitors" on the MB which
caused it to overheat and shut down.

Almost assuredly a heat problem. The question is, what is the cause of the
heat problem. You've not given any information on the CPU temperature, the
motherboard temperatures, nor the room ambient temperature. Without such
information, any replies would be guesses. As in, deteriorated electrolytic
capacitors in the CPU DC/DC downconvertor/regulator, deteriorated thermal
compound between the CPU and heatsink, dirty heatsink fins, failing case and
CPU heatsink fans, ...
