I just built a computer with a MSI K8T NEO2-F motherboard and with a 1gb stick of Corsiar 3200 memory. When I go to start-programs-accessories-system tools-system information it reports 1024mb of ram but only about 200-250mb of available physical memory. Then when i got to control panel and system it says on the general tab that there is only 512mb of ram available. Could there be a problem with the ram or is it something else? Basically the only thing running is system tools that came with the computer and excel.
