This sounds suspiciously like a problem I had recently. It may well be
heat releated. Clean the inside of your case of dust, clean the fans on
your processor and heatsink, northbridge and graphics card - dust build
up on fans causes heat not to dissipate properly and your BIOS will shut
the machine down at a certain limit to prevent burn out.
This was my problem my CPU fan was clogged with dust both on itself and
between itself and the heatsink. My machine switched off under load
(playing games or encoding audio/video) due to the extra heat generated
by the CPU load, although the PC case itself was still on. As in your
case, I needed to physically power it off and start it again.
If that fails to solve your problem, boot from either an Ubuntu CD and
select the memtest option, or a memtest86 cd or floppy (from the memtest
website) and do a memory test. Alternatively, if you run Ubuntu, choose
memtest86 from the boot menu. Leave it for a good 24 hours or so to get
heat or uptime influenced problems.
I'd put somebody elses money on a heat issue caused by either dust on
your fans or insufficient airflow and extra heat caused by adding an
