To keep cooked pasta, you have to put sauce or oil on it first. Do not keep pasta without something on it for more than a very short time or bacteria will grow and it will make you sick. With tomato sauce or something similar on it, it can keep for a few days in the fridge. The general rule of thumb on leftovers is three days. After that, there is a chance of bacteria growing on the food, which makes it not worth the risk. Salmonella, botulism, etc. are serious illnesses which can be fatal. So if in doubt, throw it out. Also, food should never be left at room temperature for more than two hours.
