Assuming Your Query Is Related To OS, You Have A Decent Amount Of RAM For A Modern Day Computer. And I Must Say There Is No Limitation On How Much RAM A Computer Has To Have A 32 Bit Or 64 Bit OS. As Long As Your CPU Supports 64bit OS (Which I Guess It Does As Almost All Cpus Sincel The Last Decade Support It).

As You Now Have A 32 Bit OS(I Will Give Example Of Windows As It Is Most Used), You Need To Format Your System Or I Say Install A New OS So You Should Take A Backup Of All The Important Files You Need To Have. Most Commonly We Have More Than One Drive Partition And You Need To Identify Your System Partition So That While New Setup You Won't Accidentally Erase Your Other Drive.

Now You Need To Have A Windows Installation Disc Or Thumb Drive (You Can Watch Youtube How To Create One). Select 64bit Version To Download For Your Setup And Install Windows Using That Done.
