just yesterday i was playin nfsu2 . suddenly the game just blanked out and i was returned to the desktop. i tried again but the same thing was happenin after a few seconds of gameplay.then i restarted the pc and it gave me a registry error. after it fixed it restarted again and then at the os startup it started givin registry error. u know the ones which have the close and details buttons. i got fed up and ran scandisk in safe mode. then i ran sfc in safe mode. after that i restarted again in normal mode and the game again blanked out. i uninstalled it and then installed it again. i was also surfin the web on firefox. durin installtion the blue screen of death appeared and it gave me a cache error. then i restarted again and installed it and again the blue screen appeared. finally i got really frustrated and shut it down. this wasn't happenin before and the game was runnin perfectly.the system's config is p4 prescott 2 ghz with 512 mb ram win 98 and 845 gv mobo. before uninstalling nfsu2 i tried to look for the save game file but couldn't locate it. could ne one pls tell me wht's the name of the file so i could back it up if somethin happens again. also could the abnormal behaviour of the pc be due to overheatin?
