Understand what you are saying about it crashing across other computers, your conclusions with this recent information make sense. But I would still try it anyway, you can always roll back drivers, you have nothing to lose and it has resolved these sort of issues in the past.


What you are really looking at:

a) Windows update resolves it inc optional windows updates (you already did it).
b) VST reset resolves it.
c) Driver/firmware updates resolves it.
d) Something odd in the actual project (e.g. corrupted project, a plugin on the master bus you forgot about). Try to reproduce the issue in new projects without the default template.

I doubt very much it is a buffers issue but you could try boosting them (inc MIDI buffers), and muck around with your ASIO latency or whatever. That's not what I'd look at first though.

That's it really. Only other advise is always have a backup strategy.
Cheers
