ok at the the bottom for my sig ull see my com specs, all id liekto say is this is my 4th day, 1st day mine locked up, but all i can tell you is, i did notice this game does cause ur cpu to runa lil hotter than normal compared to a older ver of the game i found on cnet. so mabey ur prob is cpu cooling, get a new heatsink and get heatsink compound i recomend it. adn no im not lying about my comp spec's , although the only thign that does suck, is my sound card, no game port, and my joy stick (microsoft side winder 3d pro, gameprot ver) so i had to get a midi-usb adapter, and now thrttle dont work, but thats another prob for me to fix later, well all i can tell you is, get a enw heat sink if it's retai and came with one, screw that little piece of crap, get a volcanoe 7 + , ireccomend it for athalon Xp 1500's and up.!!!! take my advise it might work.
