My computer will sometimes seize up and in the task manager it says the disk usage is at 100% but nothing is using any disk usage according to it. This will come and go for seemingly no reason. Also when I restart my PC one of 3 things will happen. It will either restart normally, it will say there is a disk error and it will repair it except when I let it repair it's self it never makes any progress, or if there's an update it will say the update didn't complete and will restart itself and redo the process. I know there are things I missed and if further information helps I would probably be able to answer.
