I am having problems playing medal of honor pacific assault. Recently I have purchased a opteron 165 processor for my pc. Since then I have been unable to play this game. During game play at random times/intervals the game will completly lock up, you will hear jittered sound, and I cannot get into windows, I am forced to reboot. I have tried downloading the windows patch for dual cores, I have tried using the win launcher xp, I have tried swapping from either core 0 to core 1 through affinity in task manager. I have tried changing from whql 93.71 drivers to the beta 93.81 drivers. I have tried running the game in its safe mode as well. Nothing has made a difference. Here is my system: AMD Opteron 165 DFI LP UT NF4 SLI-DR Expert Team Extream DDR500 2x1GB SLI 2x EVGA e-Geforce 7800GT 256MB Windows xp pro sp2 (32bit) OCZ Gameextreem 700W PSU Seagate Barracuda 350GB SATA 3.0GB/s Yes, I am an overclocker, however I have tried using bios defaults, no difference. My bios is the most current. My windows system/audio drivers are the most current, from Nvidias website, V6.86.
