    Install 64bits if you have 32bits you can have 64bits.

    i think ur miss understanding what im saying cause taking a picture of ur comp with 4 gb of ram doesn't mean, any thing win 32bit is supposed to support up to 3.25gbs..... considering my desktop has 3gb of ram atm and is showing 3gbs.... while a laptop on the exact same os with 3 gbs of ram is showing 2.75.... so that doesn't make any sence

    Plus my freinds computer has 4gbs ram running 32bit, and it reads 3.25, so it doesnt make anysence that it reads 2.75 when i have more then 2 computers around me that read up to 3.25.

    There's two issues here:

    A 32-bit computer has a 4 GB memory address space (2^32 = 4 billion). Everything that the computer accesses needs to be addressed, including RAM, video memory, network, etc. All of these items pull from addressing space, so the maximum amount of RAM on a system is technically 4 GB minus whatever else needs to be addressed. Therefore, the maximum RAM on a 32-bit system varies based on the system.

    Now, there's also the case of graphics cards pulling shared memory from RAM. Anything that the GPU pulls will be unavailable to the rest of the system, and you get reported RAM available equal to the amount of RAM in the system minus whatever the GPU is pulling.
