I have tried everything recommended on the EA website. I have an Antec 430 true power PSU, tried NO OC (XP2700), use Geil PC2700 C2 at 2-3-3-7, stock ATI Radeon 9700 pro, XP2000 OS, all the latest drivers upgrades, Cat 3.6 drivers (tried them all), DX9.0b and upgraded the game to 1.6 (I think, the latest) Here is the deal, no matter what I try, nothing changes, the game goes back to Windows with a message"A serious error has occured...." or the computer re-boots. I have tried every imaginable comination, and nothing seems to help. After 10-30 minutes usually (sometimes not for 2 hours, or not at all that night) it does this. I don't know what else to try. Anybody else find a magic cure for this game ? All other games are rock solid, and the OS.
