My computer has 2gb of ram. i am trying to add an identical 2gb chip. When I check my RAm under control panel>System with both chips installed my computer says i have only 2.5gb. With either chip installed it says i have 2gb. Any ideas why it wouldnt say 4gb with both chips installed?

No, this is an XP limitation. In the System Properties does it say Physical Address Extension is enabled?

*EDIT* Scrap that. It seems you have Vista/7. But again, do you have it enabled? If not, check the BIOS if you built the PC, otherwise the only tweaking options you get are the date and time, I am afraid :(

32-bit XP (and all other typical 32-bit OSes) is limited to addressing only 3.25GB of RAM, it cannot see more.

Perhaps he's only aware of the problem occurring for XP.
