I'm not sure but it may be a hard drive issue (about to fail?), but recently when I watch any movie files, it starts to loop and repeat the last 10 seconds. So it would play fine for about 1 minute and then it would loop back the last 10 seconds. It would do this for the whole movie and I tried viewing other movie files and it did the same thing. It did that with VLC, windows media player or anything else I use. Does this mean it could be a sign of hard drive failure? Nothing else seems to be a problem though (it's not slow loading folders or internet pages etc).
So I'm not sure what this is. Any ideas?
