You can start by noting what type of slot/socket it has for the CPU, and/or any model numbers / designations to the mainboard, as well as the manufacturer. THEN perhaps we can look up something appropriate.

If its a part number, a simple google search with this number should show results...otherwise bring it to a local computer store and ask them what you have. Dont worry about feeling stupid. This is actually a very intelligent question.

easy...\n\ngo to kingston.com and use their ram wizard...  No guess work.\n\nAnoosh's suggestion just uses the system info in the registry.  It can be inaccurate.

just open your laptop and bring it to frys or best buy and ask for the ram you want and show them your system...just plug it in where the long boards on the main board are plugged in...it's that easy really...

OOH, No stickers?!!?  There I dunno how you will.  Best way is to ask a computer dealer to try the RAM for you and give you the specs.\n\nOr better, try it at a friend's who's willing to help u out.

The website below has a feature to scan your system and it will tell you exactly what kind of slots you have for both your video card and your RAM.  I've bought RAM from them before, very good service and aftersales.\n\nhttp://www.crucial.com/

Well it depends on what type of RAM you have, not what OS you have.  Check out www.shopper.com or www.pricewatch.com for the latest RAM prices for your type of memory.

go to www.crucial.com.  On the right hand side, there is a program that scans your whole computer.  complete the scan.  It will let you know what your system's capabilities are and what you can add.\n\nEdit - All hardware is NOT compatible.  You need to know what your motherboard configuration is.  If you have an AGP slot and get a PCI-E video card, then it's worthless. Also if you upgrade your ram, you need to get the right RAM or else your computer will go haywire on you.
