Game rarely survives computer hibernation

When I hibernate my computer with the game running, it will usually give me the blue screen of death or stall for a few minutes and reboot upon turning the computer on. I don’t quit the game and turn the computer off if I am not finished because unless you finish the game in one sitting, no experience points are awarded. I can load a saved game, play it though, and it will say that I earned through levels of experience. However, upon returning to the main game screen, it will not give me credit. I could have started at level 8 and earned to level 11, but upon completing the loaded saved game, it will still say level 8. Has anyone else experienced this? Whatever is causing these issues needs to be addressed in the next patch. Loading saved games should give credit for experience points. Please help.
