My wife is playing sims 3 but after playing it for any amount of time it keeps crashing, not at any particular bit it's pretty random, then windows pops up & says , sims 3 is not working & only option is to quit game so all game data is then lost ! There is plenty memory space & we have an updated graphics card, any ideas or answers, thanks rizlaman56 peace
