On occasion, maybe once every few weeks. Last night Piriform Defraggler said i had 17% fragmentation. I started it and then went to bed. In the morning all was ‘quiet’ on my screen, no mention of a virus, or any stoppage. I ck’d Defraggler and it said 7% fragmentation. Something stopped it from running, a re-boot is all i can think of, but HOW did the re-boot happen?

Thank you, :slight_smile:
