Re: motherboard fault
I can't believe this discussion is still going. Your system is working and reporting just as it should. You have 4GB installed and it is all being recognized, your version of Windows just can't use it all. Your version of Windows has a 4GB limit and that limit includes all the memory in your system including your video card and every other component that may have some memory (as in your sound card, cpu, even some keyboards and mice). Even Windows itself will allocate some of your memory for special purposes and this allocated memory will no longer be shown as available.
Adding more memory will do nothing.
Upgrading your memory to a faster speed will only give you a mild improvement at best.
