Okay.... although buggy, Vanguard has played exceptionally well until Friday night. Nothing changed on my PC software or hardware. However, I am now getting frequent crashes to desktop, lockups, or entire system auto-rebooting. When the system recovers the Window Error is due to a driver issue. However, what driver issue? I haven't updated in atleast a month. Why now am I crashing in Vanguard? I am running AMD x4600+ with 2GB PC5400 memory, ATI Radeon x1600 Pro x16 video card and SOundblaster XFi Soundcard. I have run a full scan. Defaulted to basic settings in game. Scanned my HDD and defragged. Ran NAV. No idea. Any help will be greatly appreciated.
