hi i was wondering if there are anything that can speed up and make a computer perform beter. now i know that u can change the speed or how fast the computer runs but that u need to kool it so it doesnt over heat. i will most likely need to buy a fan. but my question is how do u change that. i know that u hit f1 and u change it their but i try it but i dont know where to change it. so if any one could help me that would be great thanx
