and I appreciate the help. But evidently I'm an IDIOT. It wasn't hard to do, the card snapped right into place with no problem. But when I plugged everything back in, and started the computer, I get this one long beeeeeeeeeeeep. So I took the card out, read the instructions again, put it back in easily, and still another long beeeeeeeeeeep. Why?I think you may have damaged the memory when installing. Is there any text at all?
BTW could a nice moderator move this to its starting topic. Thanks in advance.It could ALSO be mismatched memory or the wrong type altogether...

Did you check your BOARD specs as to what type of RAM it likes ? ?Will it do alright if you reinstall only the original memory?I am getting the same
idea 'patio'has,mismatched ram. :-?We could probably help if we knew the motherboard and all the specifics of the RAM you put in there. Not just the speed. That's the easy part.well, I realize I have no clue what I am talking about, so please tell me where I find the info about the motherboard? Oh, and I also realize I should probably just hire SOMEONE to do this, but figured I could at least TRY on my own.
My computer is a Medion MD1768DLoad and install aprogram called Everest Home and post a report here...this will tell you more than you'll ever need to know about what's inside that machine.

If you started your post by stating something like "i'm doing this for the first time, how do i" etc. then we can better tell where you're coming from.

Everyone here started exactly where you are right now so don't be afraid at all to ask just make your requests a bit clearer.

And Welcome Aboard !
