My computer's memory was 2GB and i added 4GB more, but only 2GB is usable. I have tried many time take the Ram out and put it back but i still have the same problem. Can anyone help me?
Sorry my bad English.
The memory limit on 32bit operating systems is 4gb, so you would ov been better off with just another 2gb dim. Try removing the 2gb dim and boot with only the 4gb
Can i just set a new 64bit windows?
As bradscoolio pointed out....it's a limitation of the 32 bit OS. If you want to upgrade the amount of RAM of your system you'll need to move up to a 64 bit OS. You'll need to check your system to see if it's hardware/software ready for 64 bit OS. These links should help explain the differences.

Thank for you help!! My OS is now upgraded to 64bit and it solved the problem.
Excellent! Glad to here you have it fixed. So have you noticed a difference between the two?
Do you notice a huge speed difference? Is it amazingly fast?
You can enable PAE to address up to 64gb of ram.
Go to command prompt, type in BCDEdit /set PAE forceenable
That's all.
Yeah, I noticed that my computer was still fast while i was installing 3 big programs in the same time. Physic memory was used only 80%.
