hey chesterbigbird. i've been having computer trouble, and one of my friends referred me to you. i thought it was a problem with the graphics card, but after talking to some other simmers, they say the graphics card is fine. while i'm playing the game sometimes, either in live mode or build/buy, but never in CAS, the game will freeze and my screen will turn all one color and i have to do a hard reboot on the computer. then, when i log back on, i have lost progress and have to redo a lot of things. any advice you can give me would be greatly appreciated. thank you!
