You would have to buy another stick of ram, if indeed that is the cause.
I would be assuming you only have one stick of ram in there right now. You would need to find out how much ram you have by going to control panel>system (XP)
At the bottom of the system information window that now comes up, you should see your computer's specs. Mine, for example is a p4 2.4 ghz processor with 1 gig or ram (2 x 512 sticks)
Before you buy a stick of ram, you might just want to find out if indeed, you only have one stick of ram in your computer, you'd have to open it up and check it out (probably only if you have 256-512 megs of ram). Then if you do only have one stick in there, depending on how much you want to spend will be how much of a memory of ram you should buy. You can get a 128 meg, 256 meg, 512 meg, 1024 meg, and I think it even goes up to 2 gig sticks of ram. A 512 stick of ram at a regular computer store a year ago costed me $94. If I went to another place that has way cheaper prices, I could have gotten that same 512 stick of ram for only $50. So you'd want to shop around to see what has better prices.
Hoped that helped
