Hi,I currently have a P4 1,5Ghz, 256MB RAM and a Geforce 3 64MB and I'm planning to upgrade (certainly the RAM to 512, but I'm not sure yet of the processor or videocard-so any advice on that one would also be highly appreciated), but how do I do that? Do I just go to my local store and ask "please give me 256Mb of RAM"? How do I install it?...looking forward to your replies

"Do I just go to my local store and ask "please give me 256Mb of RAM"?"No--can't do that for the same reason you can't go to a tire shop and pick up any 'ol set of tires. Depending on your system board, the RAM it takes may be different from say, my system. Then there's issues of chip coexistence--you have to be careful mixing and matching certain types of chips.You don't mention whether your P4 is homebuilt, but I'm assuming it's not, since you ask how to install the RAM. Given that, you need to find out what type of RAM is suggested by the mfr. Some mfr's only take RAM that matches their proprietary specs. I ran into this with Dell a few years back--I was trying to upgrade a server in Yuma, and not one store had Dell memory. We had to have it overnighted from Dell--a headache which cost my client some expensive downtime.If you don't know how to install RAM, try to again examine any books that came with your system--somewhere there should be one which explains how. My RAM for instance is easy to install. You ground yourself (very important), push it into the slot (it's keyed so it only goes in one way), and if you do it right, the clips will lock it into place. The RAM upgrade is well worth it. For me and working with FS2004, going from 256 recently to 384--completely different sim, and for the better.

Thanks for your reply JohnSO I found I have 256MB of RDRAM, is that enoough to tell the vender?I also found instructions how to add memory in the Dell solutions guide, so I'm all set now?

If you have a Dell, you need to find out whether Dell RDRAM is required. As I mentioned in my first reply, Dells are famous for taking Dell only RAM. And you can't always trust your local clerk at CompUSA or BestBuy...most of them (those I've met anyway) know what they know from a book or an internal class--not from field experience.
