Every time I try and play NTW I start the campaign and go to the tutorial and over many attempts at different points of play my screen goes blank and flashes as if in saver mode and my pc locks up and I have to press and hold the power button to restart it. Any suggestions as to what may be the issue.
Atm I have the following
Itel Core i7 920 @2.66 GHz
6.00 Gb Ram
and 64 bit OS Windows Vista
and my video drivers are up to date
