my iBook seems to get very laggy after playing Halo for say an hour. to the point where i litterally cant play anymore. even after i quit the game, its still laggy. just happened to me a couple minutes ago so im gonna try restarting the computer. also i know that my computer needs more RAM for Halo to function properly. i only have 256mb RAM but this problem doesnt seem to be a RAM problem. does anyone know what could be wrong? *edit* 10 minutes later, without restarting, my computer seems to be better. could it be a problem with overheating? the fan didnt go on and my A/C is on.
