I recently just purchased 2x 1gb sticks of RAM from newegg, to add on to my original 2gb. This was supposed to give me 4gb of RAM. When I rebooted my computer, I checked my BIOS to see if everything was functioning correctly, and it did say that my computer has 4gb of RAM. However, when I start up Vista, I go to Start > Control Panel > System, and the system information reads that I have 3070mb of RAM in my computer. Is there a reason for this, and can it be fixed?
