have a dell ins. 1500 laptop with 8 g Ram. Running win 10. It has always booted in 30 seconds or less. I have been online since 1998 and am ANAL about my pcs. I fix them for all of my friends.So I know all of the things to do. But something has all of a sudden slowed it down last week.NO malware, spyware, etc. I use ccleaner, malwarebytes , and superantispyware. ONLY my AV (avast) starting up. All else disable. Updates done. Turned OFF fast boot, as suggested in some posts.Runs perfectly once booted, but all of a sudden 2 minutes to boot. Suggestions? Fizes? Different software suggestions?? Check my event logs but I have no idea there. Thanks!
