buying ram?

i went to newegg and went to computer memory section and filled out the form for my computer to find compatible ram.....
i'm not really intelligent when it comes to upgrading computers, so i'm not sure if i buy a 1gb stick or something if it will actually work....

is installing ram sort of a plug-it-in and install type deal? or do i need to do something more?

i also have an old GeForce 4400 graphics card lying around, but i don't have the CDs to install the drivers, i know i can find them online, but will i be able to just swap it out with the other one?

ha! the damn video card worked as soon as i turned on the computer! :)

now all i need is some Ram an i think i'll be set :)

Installing RAM is pretty much plug it in and away you go. Just be careful you put it in the right way round, it has a small notch on the bottom that only allows you to put it in one way anyway, and that it is seated properly. I don't know what specs your computer has or how much RAM you want to get and install, but if it's a fairly modern motherboard you may want to buy a RAM 'kit' which is 2 matched RAM sticks, which might work a bit better. If you are just buying 1 stick then it's pretty straightforward.

If you can find out the model # of your motherboard, you can figure out what type of ram you can use, and how much of it.

In most cases, there are limitations to speeds, sizes and number of slots.

i looked up my computer's model, because it wasn't home-built....

i found what i wanted, but is there a way to be SURE it will work?

Check the information on the website of the manufacturer of the MoBo.
When you find information of the usable RAM u can use it without problems... (I think)

Lookup these information:
Chip / Modul
DDR2-400 / PC2-3200
DDR2-533 / PC2-4200
DDR2-667 / PC2-5300
DDR2-800 / PC2-6400
DDR2-1066 / PC2-8500

To be sure, crack open your case, and look for a part # on the mobo, and use that to verify the info you learned while researching your machines model #

I assume you're not interested in the manufacturer warranty, because opening the case/adding ram may void that...
