Version 4.2.1 fill my memory pool

Ok here is the thing, since the update of launcher i can’t run the 4.2.1. When i run the old versions everything is fine, only 20% of my RAM is used for the process.

But when i want to execute version 4.2.1, the memory pool starts to fill until my PC freezes.
I captured the next image from the task manager after i kill the process, because if i let it fill the RAM, need to hard reset my PC and i don’t want to do that more times.

I’m already verify the installation, deleted and reinstalled, run as administrator and redo all over again, nothing seems to work.
I had the same installation in my work’s PC, and with so many less RAM and power, there runs just fine.
Please somebody help me, i don’t know what to do now, before this problem i had the error with the launcher that doesn’t showed the right version installed, and i performed the update like 3 times, when the new version was already installed.

Specs of my home’s PC:

  • Processor AMD Phenom II x6 1090T.
  • 12GB RAM 1333Mhz.
  • Gigabyte Nvidia GTX 780ti.
  • Windows 7 Ultimate.
