Game crashes and Windows automatically reboots and with increasing frequency. At the beginning I could play 3-4 hours without crashing but now I am lucky if I get a hour. No apparent pattern to it as far I can tell. I have done the usual song and dance you do in these situations - updated the drivers (nvidia), tried different settings, turned off background programs. So far no dice. I think I still have my old graphics card, switching seems to be the last option. Sucks to be in this situation - game is fun otherwise...
