I have a Toshiba Satellite 2675DVD which was running Windows 98 previously. It was running with 64MB RAM, and then it was upgraded to Windows XP (with SP2). I then added a 128MB RAM chip and the OS still says base memory=64MB in the System Information window. The BIOS shows all 196000 kb. Why does XP not recognize the new memory? I upgraded the BIOS to version 7.6 also, no change.
