Ever since the computer was reinstalled due to the harddrive going kaputnik in early December, most times I exit Skyrim it now goes to a black screen for about 5-10 seconds (I haven't actually kept count, but I'd say about 5 seconds or so), then to Windows as normal. Sometimes it doesn't do it, but others it does, and it never used to do it before. Just curious what might cause this, and if it's something to worry about or not? Could it be due to me possibly using higher graphics settings?
