Sounds like you are using a 32-bit version of Win 7. 32-bit operating systems can only see 3.25GB of memory. The rest is there, just not directly accessible by the operating system.

This is normal and nothing to worry about. The only way to access all of the memory is to move to the 64-bit version of Windows 7 (or any other OS for that matter).

Good luck!
 
If it really, really is a 64-bit version of Windows then your boot settings may be limiting the amount of RAM that Windows will use. Try this:

- Click "Start", type "MSConfig", press <ENTER>
- Click the "Boot" tab
- Click the "Advanced Options..." button
- Make sure the "Maximum Memory" checkbox is UNchecked.
- Reboot

But if you're running a 32-bit version of Windows then the other posters are correct and these instructions won't help.
