If you are still having this problem after following the previous steps, you might want to go to the nvidia control panel/change resolution and set your color profile to "YCbCr444" and click apply.Now, launch one of your problem games and see if it still appears Blue. If not, revert back to the RGB profile and click apply and launch the game again. See if it looks "right" like the previous color profile does. If it looks right, turn off computer, turn it on again and launch game again.

Try resetting the color settings using the following steps: Right-click on the desktop Choose Graphics Properties (or choose Graphics Options), and then Graphics Properties... Click on the Color Correction button (or click on the Color tab). Click Restore defaults.
