I have Half Life 2 Ultimate Edition. I have played through Half Life, Half Life 2 and The Lost Coast Episode. My frame rate in the Lost Coast Test was about 170 fps. Whenever I try to play Episode One it will play fine for a few minutes, then become unstable and crash all the way to a BSOD. I can jump ahead to Episode Two and it plays fine, but I don't want to skip Episode One. Since they all use the same game engine I can't figure out why Episode One does this every time.
Any help or suggestions are welcome.
All of my drivers are current, no overclocking, no temperature issues. I can boot into Vista or Windows 7, it crashes to BSOD in both.
Thanks
