Get the serial/model number of your mainboard (motherboard) so you can research the maximum amount of RAM the machine can handle. I had the sales rep at Office Depot look it up for me after I had the model number. It's going to be a Pentium or a Celeron or whatever... Go to start - programs - control panel - system. "General" tab will give you the processor name and amt of RAM. (write that down). Then go to either "device manager" , and find "System board" or or "hardware" then "device manager" and "processor" depending on your o/s. Right click or select properties.
Wait, that doesn't get the details, only driver info. Sorry. I had the box from mine, it was a home built machine and the guy gave me all the boxes and packrat that i am, kept them all. I have some utilities on my machines that give that sort of hardware detail. (I have to count on someone to help us here)
You are going to have a limited number of RAM slots, plus a maximum amount of RAM. SO buy the largest stick (at the correct speed) and put it in the FIRST slot. (Looking down at the machine, the RAM sticks are lined up, they will look like what you have. If the old RAM stick is megs than the new one, remove it carefully - you have to slide the fasteners away from each end first), and put it in the slot behind it. Carefully fit it into the slot until the fasteners slide over the corners and then you will know it is well-seated. Make sure you touch the ram stick to a metal part of the casing to remove the static before you insert the ram. Ram is pretty much plug and play once you know the specs.
I would NOT buy RAM from ebay. It's too easy to break it (like by shorting it out). That is the one thing I would buy new. (on sale of course). They're supposedly not making PC100 (that is a speed) anymoreyou might find it at a PC repair place, used.
Rather than ebay, I'd take it to a PC shop and get a used stick and make them install and boot the machine and see if it recognizes the new total RAM. Shipping costs are a rip-off, and I have had my share of bad luck with more than one seller there... and ebay/paypal always sides with the seller.
Sorry I can't be more help on finding the serial number and speed. Do you know that already? If so, I think you're home free but I do not mind being corrected. So fellow bleepers, please post whatever's needed.
So, you have to know the speed, the max your machine can hold, how many slots you have, and do arithmetic to figure how much you should buy. It comes in sets of 128: next size is 216 then 512 and up. In the old days, I was told you had to have the same size stick in each slot or the machine wouldn't recognize. I found that to be not true in my Pentium 3 that has 3 slots but can only hold 728 megs max. Putting the largest stick in first is the trick: also, the smaller the size the cheaper they usually are. So get the max your machine will hold, at the correct speed (eg PC 100) given the number of slots you have. Sorry I was so wordy this probably could have been a short answer.
