The memory limit on 32bit operating systems is 4gb, so you would ov been better off with just another 2gb dim. Try removing the 2gb dim and boot with only the 4gb

As bradscoolio pointed out....it's a limitation of the 32 bit OS. If you want to upgrade the amount of RAM of your system you'll need to move up to a 64 bit OS. You'll need to check your system to see if it's hardware/software ready for 64 bit OS. These links should help explain the differences.
