Ever hear a strange noise coming from your computer.Maybe it sounds like a plane about to take off.That's the sound of a fan that needs to be cleaned.You may notice that your computer case has holes in the front and side.These holes allow air to pass through the case.Usually air is pulled from the front of the case over the hard drive past the motherboard and out the back of the case.Usually there are two fans that accomplish this.One fan is usually mounted on the back of the case and the other is in the power supply.Like wise you need to upgrade your system's RAM to make it smooth,fast and cleanmemory offers you just that.
