Looking for a new laptop for basic internet usage and basic home computer work. Any suggestions?

I currently have a Dell Inspiron 8200 from about 2002. Want something faster and more powerful for internet use, managing videos and pictures and basic home and internet use. How do the different processors compare. How much hard drive space and memory would you suggest? Would like something light weight for travel.

How to wipe a hard drive without internet connection?

I have an old dell compy and it is without a working internet connection…I would really like to wipe the hard drive and reinstall windows, but all the research I did on the internet was no good (on my desktop, btw). Is there any way to wipe the hard drive then reinstall windows without downloading a program off of the internet?
