My laptop has 12 GBs of RAM installed, but it said that only 2.41 GBs of RAM is usable. How do i change this.

Done. It didn't detect any problem but then it still says that that only 2.41 Gigabytes are usable. Im even adding a photo showing the problem. Take a look at the Installed RAM.

No restart button in task manager

another easy way to kill tasks, download and install Winaero Tweaker(free) and theres a setting to add a Kill non responding tasks using the desktop right click menu. When you place your cursor on the desktop anywhere and right click the option is at the top of the list, Very handy and you dont have to go through all those steps and well Winaero Tweaker has alot of cool Windows tweaks. Just posting a different suggestion, Im sure your ok with what was suggested here.
