I'll go against the trend here and say I've had an absolute sh!tload of BSOD across all the builds.
Some have been due to overclocking, some have been video drivers

Apart from one set of bad Catalyst drivers, Vista remained rock solid while Seven crashed left, right and centre.
On the plus side, with each successive build, the amount of Blue screens has diminished drastically
