The nameless PSU is probably the cause then. It would work ok with the 
older CPU but can not keep up with 2cores...
I would focus on that, since you already tested memory and the rest of 
the components seem standard.

In ports you will find a few programs for stress testing, e.g.:

math/mprime (in "torture" mode)
sysutils/cpuburn (specifically for CPU stress testing)
