so i got some new sticks of ram for a total of 4 gigs, but it is only showing 3.25 gigs in there, i am using a core 2 duo computer which i assumed was capable of reading more than the memory limit for ram. what did i do wrong?

You assumed wrong. Why would a CPU magically be able to "read more then the memory limit?"
3.25GBs tells me you have a 32bit copy of windows. That's all your going to get. You'll have to get a 64bit copy if you want all four gigs. The difference between the two is real world nothing so I wouldn't worry about it to much.
Edit: Just looked at your pic, you have a 64bit copy. Look in your bios for something called memory remap or something like that. It should get you want you want.
Read my edit. You need to flip that setting in your bios. Every bios might call it something else but it should be something similar.
ok, it wont let me edit just about anything in the bios, but i did find something that said that my base memory was 640k, and then my extended or something memory was the rest of it.... how do i change the base memory to something smaller? why is it holding this much memory?
Assuming Jim is right its your bios thats not setup for 64bit. It will run 64bit windows ok, but the memory controller found in your NB located on your motherboard can't. Its a 32bit only controller? Something newer then a 945 will probably allow you to use all 4GB. I vote that you don't worry about it. The performance difference between 3.25 and 4.0GBs is nothing.
