I purchased the full version of Bioshock for the PC. It installed ok but I had to turn off most of the options to get it to scroll more smoothly. The problem I have is that when I start playing part two (Neptunes ???), the PC makes a sound like the Hard Disk is struggling, then the screen goes blue, immediately filled with white letters (Almost like the Blue Screen of Death) and then my PC shuts down and restarts. It happens every time at this same spot in the game. My PC: HP Pavilion a1440n 820 Intel viiv (Intel Pentium D (Dual Core)Processor GeForce 7300LE graphics card 2 GB RAM 350 GB Hard Disk OS is Windows XP Home Media Center w/Service Pack 2 I have read on another thread that AVG Antivirus may recognize the install through the internet as a virus threat. It results in the game not being able to be played. It has been suggested that I do a re-install. Anyway, thanks in advance for any help I receive. Cheers!
