New laptop slowing down already!

I was convinced getting a new computer would solve all my problems. I use it daily and need it to work quickly and efficiently for me. It seems that we may need some new laptop memory or maybe we just got the shaft on buying the wrong computer. I have asked my friends and family that know a lot about computers and am hoping they can help us with the issue. If not, it looks like we will be paying someone to fix it or to install more memory.
