Crysis was working perfectly. Then I got to a level right after you kill the first dropship and I decided to take a break. When I reloaded the game I got flickering, but when I look closely, the image when you first begin the game seems to be "burned" into the screen... and when light tries to bloom I can see the frozen image in the background.... I need help!!

HELP!

To be more specific, the game seems to be covered completely by a shadow and when I move it lightens up randomly and shadows form ALL OVER the place. Also, when I look down the sights of the gun, the game blanks out for a second, as in a black screen comes up for a solid second or two before the iron sights/scope is displayed.
