Why is my computer taking so long to boot up?

Episode 1672 (14:41)

David from Wichita Falls, Texas
Windows 10

David turns his computer on, and occasionally, it takes its time booting up. After a few times booting up longer, it will boot up quicker. Leo says the number one culprit is a failing hard drive. The drive may have bad sectors that Windows is having issues reading. Once in awhile could also indicate an update of some sort. Leo says that David should keep an eye on it and if it gets worse, consider backing up your data and getting a new hard drive. Or you could also reinstall Windows first, and see if that repairs the OS. Another thing to do is turn off Windows Fast Start. That can actually slow down boot-up times.
