Thanks people, for helping me, but finally I upgrade my vaio with memory of dana-elec (3rd worldleader memory components wich are 100% compatible with vaio's) and everythings works ok.
FOR CHECKING YOUR NOTEBOOK OR DESKTOP, I SAID CHECKING REALLY THE WHOLE SYSTEM FROM YOUR HARDWARE, SOFTWARE, EVERY COMPONENT WITH EVERY INFO ABOUT IT, CHECK WWW.LAVALYS.COM AND CHECK THERE FOR THE EVEREST HOME EDITION FREE DOWNLOAD, AND THEN YOU CAN SEE EVERY LITTLE DETAIL OF YOUR DESKTOP/ NOTEBOOK!!!
