I have some problem with the The Elder Scrolls V: Skyrim. Actually, while playing the game, I get black screen after every 5 minutes of play. After a few seconds it comes back with the FPS dropped to 70 to 20. Now I play on medium at 1680x1080 as that is my recommended setting. But after the FPS drop the lag becomes unbearable so I have to restart the game with the lowest settings available, and that gets me onto about 22-25 fps. Can you guess that what is the reason for this and how this can be resolved?
