Run with minimal parts, ie one memory module, cpu. hd & gpu.

Was the system overclocked? try a doing a CMOS reset.

if its not a heat issue then ...

try different ram in different slots,
check all your power cables
try a different psu
try a different cpu

if none of that works it suggets mb failure?

if it's just auto shutting down during bootup then must be something from bios telling it too have you tried to quickly jump into bios screen at look at the cpu temp
