I think you need to know what a motherboard you have.
Then you can google it!
You can free PC Scan programms. They say you the name of your motherboard
Who the heck said 32bit = 4gb of RAM? That's ridiculous.
Anyway, your computer can accept 2 GB of RAM, and has 2 slots for it. You already have atleast 1 of those taken by the RAM stick[s] in there right now. If it's a 512mb (1 half of a GB) then you'll need two buy 2 1gb sticks (1 to put in the new slot, and 1 to replace the old one with) to get the full 2gb available. If it's a 1gb stick in there already, then you'll only have to buy another.
When shopping for RAM, you want to buy DDR 184-Pin Unbuffered RAM. This is the only type compatible with your computer. Unbuffered is sometimes represented as -U. You can search for this term exactly; "DDR 184-Pin Unbuffered RAM".
Here: I even did it for you here. (Don't worry if it's 'for Dell' or 'for HP'. It doesn't matter.)
@PartyPooPer, just because your system is 32-bit and can hold 4GB of RAM doesn't mean that all 32-bit systems can, or that every system that holds 4GB of RAM is 32-bit.
You need to know what RAM model and type the sticks have first. Then you can proceed from there knowing which model and type you're going for in order to finally upgrade to something better that has just the right model and type but also with the highest possible amount of RAM you can place inside your PC. Hope that answers your question.

Also depends what OS your using. XP can USE a maximum of 2 gigs, Vista can USE a maximum of 4 gigs, and Windows 7 i think can USE a maximum of 6 gigs. Go ahead and add in more, but your computer isn't going to use the extra amount. Like don't bother adding 4 gigs of RAM for XP, it will only use 2 gigs.
@Vetle and PPP:
It can work, but it will probably not be worth the extra cost because XP itself uses very little memory and unless you are doing some seriously memory intensive processes. ( eg. large [ I mean REALY large here ], 3D sandbox rendering/loading ) it is not really neccisary.
