Reinstall issues

My Windows 10, that has been running fine for 2 years, suddenly would not boot. I then got the 10 download from Microsoft with my code and reinstalled it.

It has been a nightmare-sometimes taking 5 minuets or more to boot up and freezes constantly. I did some changes-recommended by Microsoft- and it is a little faster on boot up but still takes forever. Once it finally boots it works fine. Can't think of anything more to do. I reinstalled it with the download from Microsoft and it just made it worse.

Are you trying to install onto existing partitions on the drive, or have you used the install media to do a totally clean installation by deleting all previous partitions and returning the drive to 'unallocated space'.

Its possible you could have a hardware issue such as a failing drive.

Be aware that deleting the partitions will remove ALL your previous data and files. Nothing is left.
