According to AMD's tech docs an Athlon 900MHz typically uses about 16
Watts more then a Duron 700MHz CPU, and about 19 watts more then a
Duron 700MHz at full load.
It could be the 250W PSU (12V rail) can't handle the power requirements
of all your hardware and this faster CPU.
btw, the Athlon 900Mhz is a 1.75v part, your vcore is fine.
