Hi everyone
32-bit operating systems typically recognize only around 3GB RAM. If you have installed more RAM than this, then chances are that BB will not recognize the entire installed RAM. (To check the amount of RAM that is recognized by the OS, type the command free -m or gnome-system-monitor in Terminal.) To add support for the full amount of RAM, you need a Linux kernel that supports PAE (Physical Address Extension). To do this, enter the following commands in Teminal.
sudo apt-get update
sudo apt-get install linux-headers-server linux-image-server linux-serverReboot and re-install your graphic drivers such as Nvidia , Ati,, ecc,,,,
Ps: do this only if you have 4GB Ram or higher .
Enjoy the full power of your pc
