With the investment MS made in drivers
for the Windows 7 installer and via optional Windows Updates, you really only need to seek other drivers if one is missing or performance dictates.
With your bluescreens, I would have troubleshot it thoroughly in error logs then if still a problem tried the mobo maker's chipset - with the ability to roll it back if there was no improvement.
Since you report no continuing problems, I would wait to see how performance pans out. **A small inexplicable exception to this is that NVIDIA chipsets may report a missing "CoProcessor" driver which requires the factory or NVidia chipset to remedy. (Maybe someone from MS will see this one day and fix this oversight)
