hi i have window 7 32 bit with 4gb of ram and my computer says only 3 gb usable does this mean that the 1gb is doing nothing and is their a way to fix this without upgrading to 64bit?
There is no way you can fix that without upgrading to 64 bit, no. However, your product key should still work for 64 bit windows if it's an OEM product key, and you can download a legal ISO and make a USB install key to upgrade.
