How many Mb of RAM do you have? If you have only 32 or 64 MB, you should consider doubling or tripling your RAM. Right-click on My Computer, and one of the tabs should show system information, including mb of installed RAM.

Your computer manual might state the maximum amount of RAM allowed for your particular model. If not, and if you have a Compaq or HP computer, go to www.compaq.com or www.hp.com, click on the Support link and find the link that lets you email a question. They usually respond within 24 hours and and are most helpful. You will need to fill in several blanks including your make, model no. and serial number, so have that information handy.

Then call your local Office Depot, Staples or Office Max store, ask for their computer memory 'expert,' and tell him what brand of computer you have - including processor speed and type of coprocessor (this should be on that system information tab). They will tell you exactly what dimms, simms or sodimms you need and how much money it will cost. Manufacturers of RAM (often Kingston) offer rebates. These stores can usually install the RAM for you at a nominal cost (unless you are a techie and know how to do it yourself-but then you probably would know that extra RAM should solve the problem you are having). Or have a techie friend do it, but be extra careful of electrostatic discharge - one wrong touch and you can blow your entire motherboard (anyway that's what I am told, so I don't fool around).
