As eluded to in this post... 32 bits Win can only "see" 4 GB .... some of that address sace is reserved/used by hardware, like motherboard components or onboard graphics etc. So windows can only "see" 4GB .. minus these reserved components. My laptop is same as you see - I have 4GB in, but it can only reports 3 GB as avail - the rest is used by these reserved components. If you had 64 bit windows, windows can "see" much more and so can use the full 4GB. Cheers Can't find your answer ? Ask !
