What happens if you use 100% of RAM?

If the memory usage is close to 100%, this can slow things down a lot. This is because the computer will then try to use your hard disk as a temporary memory store, called swap memory. Hard disks are much slower than the system memory. You can try to free up some system memory by closing some programs.

How can I make my 4gb RAM usable?

The best possible for this is that maybe you are using a 32-bit version of your Operating system, switch to 64-bit and the problem would be fixed.

Does it hurt to have too much RAM?
