My Specs:
Core i5 760 @3.8 GHz
4GB DDR3 @ 1440 MHz
GTX 460 AMP @ 840 MHz

Whenever I install big softwares (like games) it uses up like 95% RAM and only option is a restart after finishing installation. That I can take but it's also happening in crysis 64bit. after 5 min of gameplay 100% RAM gets used up and I have to close the game as it goes to 5 FPS. My crysis 32 bit is corrupt and is not an option. Does this happen to everyone? I cant afford more than 4 GB RAM. Please reply.
 
I don't under stand the 32 bit and 64 bit Crysis? I can install my copy on 32 or 64 and it doesnt have option to pick 32 or 64. I haven't heard of a game using up all the memory to a point to were you have to restart the game.
