So recently I bought an Asus g73jh-rbbx05. I bought a couple of games, and downloaded some hardware stuff. I want to keep it as fast as possible. When nov comes round I want to get black ops, and have run it's best. Would it be a good idea to reset it back to it's factory state (pretty much to get rid of the games and hardware that I would never use) or should I manually remove them, and then perform a disc cleanup? What would be the most effective way of maximizing my pc's speed, graphics, and memory that's safe and reliable?
