So I yesterday my computer slowed down all of a sudden. I was opening a new window and it was like watching a slide show with how slow it went. I rebooted and I took 15 minuets (normally 2 min). I ran the HP diagnostic tool and everything passed but took it 5 hours to complete. The memory part took most of that time but said it passed. I haven't changed added anything for about 2 weeks.
