If you are using two sticks , one could be dead.
Pull them both out. Put one in slot 1 and see if it boots up with 2GB.
Then put the other one in slot 1 and see if it boots.
If they both working sounds like windows is reserving it for something. I know mine does it for the onboard video card. So could check your bios to see if onboard video somehow activated. or if some of your ram is being reserved to your actual gfx card.
Also check max memory setting in bios, my need to reset your bios if something gone loopy.
