my macbook pro freezes makes 3 beeps and want do anything

Beeps shows a hardware problem, in your case, related to RAM > http://support.apple.com/kb/ht2538

As you can see, it shows that your memory is damaged, so it means that your memory is corrupted or that memory slots have failed. It's not expensive and you can buy memory from OWC or Crucial > http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3

If after installing this memory the MacBook Pro still beeps, there would be a problem with its memory slots, so take your MacBook Pro to an Apple Store or reseller. The logic board has to be replaced by a different one

Three beeps at startup indicates the problems with your system's RAM modules. Have you performed any upgrades on the system, especially RAM upgrades? If so then open the system back up and try re-seating the RAM modules. If one is loose or otherwise not properly seated for some reason then it may result this error. If the problem persists even after reseating the RAM modules, then try replacing them either with originals or with new modules. If at any point you can get the system to load and not make these beeping sounds, then immediately reboot the system into the Apple Hardware Test suite and perform an extended memory test. This will take a while to run, but if there are any errors shown with this test then replace the RAM modules in your system.

Reset the NVRAM.
