Have a look into Resource Monitor > Memory tab whether there is some hardware reserved (to the left of the colored bar before the green section).

yes i checked and i have 130mb reserved. what exactly is that reserved for and how do i find out what has reserved it .how can i reclaim it if its not for anything important..

My first guess would be that you have an on-board graphic which uses that RAM. Can you tell us your graphic hardware. If you hover over the gray square box in Resource Monitor, it will give you some generic info.

i use an ATI radeon xpress 1150 831mb hyper memory

Yeah, that uses 128MB of your memory. ATI Radeon? Xpress 1100 Series for AMD Notebooks - Specifications
