That is normal and typical.
Some Windows XP machines will read 3.5 GB, but most will only read 3.0 GB even though the memory is good.
If you installed Windows VISTA or Windows 7, they would read all four gigabytes.
There is nothing rong with your computer... The makers just designed for the future by accepting four gigabytes.

You may want to check if there's a newer BIOS for that mainboard, http://www.gigabyte.com.tw/Support/Motherboard/BIOS_Model.aspx?ProductID=2993 .

Some BIOSes have an option for memory remapping which helps in this 4 GB issue, however I didn't see that when I checked that mainboard's manual...
