2 things happen when I attempt a shutdown, sometimes it freezes at the shutdown screen and I have to manually power it off, or I'll tell it to shut down but it only reboots. Though, I am able to shut it off properly when it boots up the second time. I assume it has something to do with a program I am running, because like I said I can shut it off after I reboot it (when I have not run any programs yet). I have heard it may be my antivirus, I have malwarebytes and avira, and avira. Sometimes when I try and shut it down I'll get a message that some random file with a bunch of numbers can't be closed out of, and it'll ask if I should terminate it anyways. I do but then it just results in the same thing it usually does, either the shut down freezes or it just reboots. I can't think of anything that I've downloaded recently that might have affected me, as the last thing I downloaded was some game from steam. I've had my computer built since christmas and this problem has only started since a few days ago. Please help if you can!
