Hi:

 

If you are running a 32 bit operating system like you posted, the maximum memory a 32 bit operating system can 'see and use' is 4 GB.

 

So, 2.99 GB usable out of 4 GB is pretty normal, the 1 GB going to support the shared graphics memory.

 

In order for Windows to 'see and use' most of the 8 GB  of memory, you need to install a 64 bit operating system.
