I am losing my mind with this problem! I just bought the Sims 2, downloaded it without any diffuculty, but when I run it I can only stay in it for a few minutes before my computer shuts itself off. I can keep my laptop on allnight and it will be fine to work in the morning, but when i try to run software it shuts off. I tried downloading nortin antivirus and in the middle of the system scan it shut off, without fail, all seven times i attempted (so far it had found 19 viruses)... how am i supposed to fix this if i cant even get through a system scan to determine what the problems are?? Should i clean the memory and start fresh? Should I spend money and take it somewhere to be looked at? I know I don't need to play the sims, but i paid for it, and i cant return it, so i want to know how to fix this problem. PLEASE HELP !!!
