My laptop has a case of CRS!

My laptop computer memory has a serious case of CRS!  I kid you not!  I really love having the laptop but honestly I have to tell you I barely use it because it just lags, its so slow since Windows Vista is in it.  I have a few folks I know online who absolutely love it, but I just don’t.  Many of my games I enjoy and other programs I have just flat out won’t work.  Heck even it they did I am afraid to add them and make it slower.  So right now it just sits and collects dust but I turn it on once a week to do updates but that’s about it.  I really don’t know if adding more memory will solve the issue or not.  I thought about writing to the computer manufacturer to see how I can go about switching to XP.  I am getting very close to sticking it on eBay!
