CPUs are piss easy to install.
It is just a case of dropping it in a slot, putting the fan on top and securing it.
The mother board is a little more tricky, but so long as you are cautious, the
manual should allow someone with no former knowledge to achieve it.
The exe I referred to is, indeed, part of a starforceless install, but it still didn't
like vista as it does not disable all starforce features.
I have since got hold of a copy of SH3 with no starforce at all and it's running
great.
