computer upgrade

Few days ago, I heard my daughter Alyssa complaining about her Sony Laptop computer being so slow. I told hubby about it and he said that for a three year old computer that she had, it's quite normal that the system is no longer running like new. All it need is a serious ram upgrade for now or else better to buy new one. I tried surfing on the net hoping to find one compatible RAM for her Sony laptop Computer and glad to came across 4allmemory.com. A one stop shop memory specialist!
