Hi I have a DELL inspiron 1300 laptop with 1.5ghz (celeron i think) processor and 250mb RAM (shared graphics memory). TBH its pretty pants, but does what i need of it

I'm looking to upgrade the RAM to maybe 1gb and maybe a faster processor. Can some one please tel me what type of RAM i need and how many sticks (can it be used singular or in pairs) and also what exact processor type i need.

Also a place to buy them from over the internet would be very handy

Thanks for any help

Bri.
