 Someone reinstalled MS Framework .4 and solved his issues with that, but I have not been able to play with my system since yesterday.

 Thx.  I'll try that.
Not getting any launcher (not anymore anyway) or display driver error messages though - just crashes and then reboots itself - very dramatic.
Sometimes happens within a few minutes of starting a mission, sometimes 20 minutes in.
Can happen anywhere, not just over cities, for example.
Perplexed and slightly concerned, because that's a pretty serious thing for a PC to do!
