Crysis windows 7 64 bit crashes if changes are made?

Hi I got my new computer today and I can't figure out why it's crashing for example it will crash if:

The resolution is changed, in-game keybinds, or anything that will increase or decrease graphics.



But before you say my computer can't handle it or something like that because I know it can't be that lol at very high = maxed settings with 1600 resolution I get no lag at all. I ran windows update and no more updates are left. Please help! TyCrysis windows 7 64 bit crashes if changes are made?
I have crysis on my windows 7 64bit and it's fine something must be wrong with your config file maybe a mod is messing it upCrysis windows 7 64 bit crashes if changes are made?
yes it will crash if you try a higher resolution because your graphics card cannot handle it, you will have to choose a lower one instead
