To take you literally, if all you loaded on your 'vanilla' machine was what you stated, no wonder poser crashed. Come back and post when you've installed all your cpu, gpu, via, bios, etc...etc... drivers, updates and patches... Poser5 is expecting your system to be up to date. More so if your running sr3, so get out there p5's and get your updates<< My system IS up to date. Please don't make assumptions about my hardware.
