My computer has been running really slow lately, so I thought I would upgrade it by putting in some more memory. I found a great online store called MemoryStore.com that has memory for almost any computer. Say you need some IBM memory. All you do is choose IBM as the manufacturer of your computer, then click on go. The page will list all of the IBM computer models to you to choose from. Once you find you model, simply click on it and choose “List Upgrades.” You will be told the memory specifications of your model AND they available upgrades. Choose what you like and purchase. Really easy.
