I have a computer with a 4g ram that's supposed to run all the games I have smoothly and it does. The problem is that they keep crashing. They don't lag or anything just crash suddenly. If a game is loading and I click the mouse it immediately closes and the same happens for other programs and games. The weird thing is I used to play it on a pc with 1.5g ram and none of this used to happen. I feel like this pc can barley run one process at a time. If an update pops up in the tray the game would close. Note: I'm using a 32 bit system so I know that it can't use the whole 4g ram but as I mentioned this didn't happen on another pc with lower ram. Besides I can't upgrade to 64 bit anyway so I didn't see the need to buy more ram.
