Hi people, currently I am playing Sims 2 and after 5 or so minutes, my computer starts making siren noises. Once I quit the game, the siren soon stops after. I have also experienced this problem when running other programs such as the ePSXE emulator( a playstation emulator) and Gunz the duel. Can anyone suggest what I could do to stop this noise? I'm thinking the computer is overheating so perhaps I can quit some background program that are running??
