There are some instances when you need to know what is inside your machine but you just dont know how. Instead of finding those neatly kept manuals (if they are still there) or trying to look into your bios , or locating system information in start menu or or worst opening your machine and physically inspect it , try downloading CPUID and the rest is magic . It is a freeware so no worries on licenses . Heres a snapshot of my Neo machine that I bought last June 2007 . By the look of it , I definitely need a well deserved upgrade !
