I am using Windows 7 and Ubuntu on the same machine. Earlier I had 3 GB of RAM,but now the Windows is displaying just 1 GB of RAM. Please also find the output of the free command in my Ubuntu :

           total       used       free     shared    buffers     cached
Mem:       1008208     904808     103400       5736      13516     239596
-/+ buffers/cache:     651696     356512
Swap:      3127292      10252    3117040

Has the swap memory consumed my 2 GB of RAM? Will I be able to use the whole of 3GB of the RAM in my Windows?

Update : I tried to run the lshw command and I got the following output :

*-memory

       physical id: 1b
       slot: System board or motherboard
       size: 1GiB

          slot: Bottom - Slot 2

Why it is able to detect the vendor/product name of the bank-1 RAM, why can't it detect the RAM size and other details ? Has my RAM got faulty?
