i have a 4Gb Ram and it's not used all by the computer always only 2.7 Gb is used my question is how can i make the Pc use all the Ram ?.

you can not.
the pc only stores in the ram, it needs to store.

Windows OS decides how memory is used. We cannot change how that works.

All the RAM is always available for it, but if it's not using all of it, that's because it doesn't need to at that moment.

If you have a 32 bit os, some of the 4gb will be carved out of it for fixed buffers leaving less than 4gb available.

Then, windows will keep unused code in ram in anticipation of fast reuse.
It will always have some ram available to use instantly.
It will do this by paging out the least recently used code to make space available.

You can try disabling prefetch and other indexing services. Might be able to save a few MBs is all.

Else You will need to upgrade RAM to more than 4GB if your system supports. Also have to be on 64 Bit OS.
